The best supply ventilation for a cottage. Installation of ventilation in a private house. Frivent ventilation equipment

In most cases, modern private houses are not built from natural "breathing" materials, but from artificially made, completely impermeable to air. Therefore, a self-built or purchased country cottage must be equipped with a ventilation system. This will make life in your home much more pleasant and comfortable.

Varieties of systems

The cottage should start with the choice of the actual type of equipment itself. After all, country houses can have a different layout and area. A modern ventilation system can be:

supply;
exhaust;
supply and exhaust;
supply and exhaust with recuperation.

The correct choice of equipment will make it possible to make the air exchange in the premises as efficient as possible without overspending in terms of electricity consumption.

Supply ventilation system

This type of climate control equipment is usually installed in small cottages. With the use of fresh air ventilation, you can make the air in a country house much cleaner and fresher, often even at no extra cost. Equipment of this type can be:

Channelless... In this case, fresh air enters the premises through the supply valves mounted in the walls.
Duct. It is structurally more complex ventilation of the cottage. Air enters the rooms in such systems through plastic or metal highways.

Exhaust system

This type of equipment is also usually used in small houses or in those built from "breathable" material, for example, the same timber or log. Exhaust ventilation in a cottage can be used both for air circulation and for removing various odors or moisture from the premises. Its main structural element is an installation designed to pump out polluted air from rooms to the street. Most often this is a regular fan. There are only two types of such systems:

Local... Such ventilation is used if the source of pollution is strictly localized. The main task of the equipment in this case is to remove it before it spreads throughout the premises.
General exchange... This ventilation of the cottage covers the entire space.

Supply and exhaust ventilation

It is the most effective used in cottages most often. In this case, both types of installations are mounted - both supply and exhaust. At the same time, air circulates through specially laid highways. Most often, in our time, supply and exhaust ventilation with a recuperator is installed in country houses. With the use of such a system, it is possible not only to make living in the house more comfortable, but also to minimize heating costs.

Ventilation of the cottage when using such an additional device does not lead to overcooling of indoor air in winter. A recuperator itself is a special design that removes heat from the air removed from the premises and gives it to the incoming air.

Features of installation of the supply system

The assembly of this type of equipment is not particularly complicated. Most often, in private houses, not even an air supply unit is installed, but simply valves. The latter are pieces of plastic pipes insulated from the inside with mineral wool. To install them, holes are simply made in the walls. Outside, each valve is closed with a mosquito grid.

In the room itself, special plastic heads with a filter and a damper are mounted on the pipes. These devices allow you to regulate the intensity of the air flow entering the rooms from the street. The result is essentially a cottage. After all, no energy-consuming equipment is used in this case.

The system is, of course, a little more difficult to install in a cottage. In this case, a supply unit is installed in the basement or in the attic. Valves are also inserted into the walls. But in this case, it is not the head that is connected to them, but the highways that supply air to the rooms. The result is a very efficient ventilation system for the cottage.

Features of installation of exhaust systems

The simplest equipment of this type is usually installed in the kitchen - above the gas stove. The hood is attached to the wall either on brackets or on self-tapping screws. Further, it is simply connected to the mains with three wires (phase, zero and ground).

In bathrooms and kitchens, the common is often installed.It is an ordinary riser, embedded in the wall and overlooking the attic or roof. To improve the efficiency of such a system, many homeowners additionally use an exhaust fan. The latter is mounted directly into the outlet of the riser. The procedure in this case is as follows:

If necessary, the ventilation duct that goes into the bathroom or the kitchen expands (but it is better to immediately purchase a device of appropriate dimensions).
The fan is inserted into the duct.
The voids are sealed with polyurethane foam.
The hood is connected to the mains.

At the bottom of the bathroom door, when using such an addition, a hole should be made in the riser for the flow of air and closed with a grate.

Equipment selection rules

When buying a supply and supply and exhaust ventilation system, the owner of a cottage should first of all decide on its performance. You will also need to decide which type of duct to buy. Today there are only two types on sale: rigid and flexible. The second option for self-assembly is best suited. The fact is that flexible air ducts are much easier to pull over the ceilings and behind the sheathing. Indeed, in this case, you do not need to make too many knees and joints.

What should be the performance of the system

The ventilation of the cottage is calculated as follows:

the total volume of the premises of the house is determined (V = S x h, where S is the area in m 2, and h is the height of the ceilings);
the required air exchange rate is calculated.

The latter indicator is determined depending on the type of room. For living rooms, the frequency rate according to the standards should be 1-2 volumes per hour. That is, the obtained result V in this case must be multiplied by 1 or 2.

The technical characteristics of air handling units usually indicate their maximum performance. After connecting the air ducts, this indicator can significantly decrease (by about 20-30%). This must be taken into account when choosing an installation. You should not be afraid to buy equipment that is too productive. All modern air handling units have a fan speed control function. Using it, you can achieve a faster or slower air exchange in rooms.

How to mount a supply and exhaust system

The ventilation methods described above are suitable only for very small cottages or for houses of a large area, but built of wood or foam blocks. In a large residential suburban building of 2-3 floors with brick or concrete walls, complex supply and exhaust ventilation should be installed. In this case, it is necessary first to draw up a project for laying the system highways and determine the location of the installation. Ventilation of this type of cottage is being installed in several stages. When arranging, the following are carried out:

Punching holes in the walls for the valves of the supply line.
Laying of supply and discharge air ducts.
with recuperator and air duct connection.
Installation of a heater.

Supply and exhaust ventilation of cottages: laying of air ducts

The procedure should be approximately the same as in the case of installing the supply duct ventilation system. That is, holes are previously made in the walls for valves insulated with mineral wool. After installing the latter, the supply lines are connected to them. They are pulled through the rooms according to the drawn up project. In rooms, supply air ducts are usually removed at a height of about 30-40 cm from the floor level. The laying of highways is carried out behind the wall cladding and along the ceilings. They are attached to the structural elements of the house with special clamps. At the same time, air ducts are bred to the sleeves using tees.

According to the standards, one outlet of the supply line can fall on 2-3 rooms. In this case, however, the features of the building layout must be taken into account. At the same time, holes covered with decorative grilles should be made in the doors of those rooms where the air ducts do not directly fit.

Exhaust air ducts from the premises are discharged at a distance of 30-40 cm from the ceiling. The ventilation device in the cottage in most cases involves just such an arrangement of the sleeves. This is due to the fact that warm exhaust air, as you know, always rises upward.

Installation of the air handling unit

Actually, the equipment itself, which is responsible for the supply and discharge of air, is most often located in the attic of the house. But sometimes the air handling unit is also placed in the basement of the cottage. Mount this equipment on a level, horizontal, stable surface. The air ducts are connected to the unit through the branch pipes. Which one to which output you need to connect, you can see in the instructions attached to the equipment.

Installation of a heater

Sometimes the ventilation of the cottage is supplemented with this element. Its installation is considered an optional procedure. However, experts still advise installing a heater. This device is intended for additional heating of cold air coming from the street in winter. Among other things, if there is an air heater in the system, ice does not form on the recuperator (which is a sore spot in the supply and exhaust systems).

Installation of this equipment involves connection to the supply line and the power source. In ventilation systems of small cottages, electric heaters are usually used. They are simply plugged into the network. Water models used in systems of cottages with an area of 150 m 2 or more cut into the distribution of the heating system.

What you need to know

You can install supply and exhaust ventilation in the cottage with your own hands if you wish. Technologically, the procedure is relatively simple. But the design of ventilation for a cottage of this type should still be entrusted to specialists. This will allow not only to save on the number of laid air ducts, but also to avoid all sorts of unnecessary problems in the future. The fact is that the slightest mistake in the design can lead to the fact that the system will work ineffectively, and at the same time it will also turn out to be energy-consuming. In addition, all sorts of mistakes when choosing a place for laying highways can cause worse problems, for example, the appearance of a toilet smell in the kitchen or bedroom.

If desired, the supply and exhaust system can be improved by supplementing it with other types of climatic equipment, filters, etc. Simultaneous ventilation and air conditioning of a cottage, for example, can make living in it as comfortable as possible. In this case, special air cooling units are usually used, which come with the system itself.

Features of installation of ventilation in the pool

In residential premises, as mentioned above, the air exchange rate should be 1-2 volumes per hour. For pools, this figure is four. After all, the air in this room is always very humid, which negatively affects the decoration of the walls, floor and ceiling, all kinds of equipment, household appliances, etc.

In order to ensure a comfortable stay in the pool, it is important to properly design its ventilation system. To prevent the ingress of humid air from this room into adjacent rooms, it is necessary to ensure that the amount of exhaust air is slightly larger than the incoming one. In this case, dry streams from nearby rooms, on the contrary, will begin to flow into the pool.

Among other things, it should be mounted in the cottage in such a way that the windows are well blown. Otherwise, in the cold season, the glass will begin to fog up, as a result of which ice will appear on the frames and sashes.

Who develops projects and how much does installation cost?

Self-assembly of the supply and exhaust system is possible. However, in most cases, the owners of cottages still prefer to outsource this work to specialists. It is usually possible to order a cottage ventilation project and installation of a system from the same company that sells this type of HVAC equipment. The cost of work in this case will depend on the productivity of the installation. Below is an approximate list of prices for such a service:

from 300 m 3 / h - 26 800 rubles;
from 700 m 3 / h - 34 600 rubles;
from 1500 m 3 / h - 53 300 rubles;
from 2000 m 3 / h - 71 900 rubles.

For the laying of rigid air ducts, you will have to pay about 350 rubles / m, flexible - 100 rubles / m. Sometimes the lines of the heating system can be additionally insulated. Such work costs about 100 rubles / m.

Conclusion

This is how the ventilation of the cottage is going. This procedure is relatively simple, but requires accuracy and precision. And if an exhaust fan or a supply valve can still be mounted independently, then it is worth taking up the assembly of complex systems with your own hands only in the most extreme cases. It is better to hire specialists to arrange such ventilation.

Indoor ventilation is a collection of ducts, pipes and fans that create air circulation and improve its quality. There are different types of ventilation systems depending on the type of room. To establish a correct and effective system, it is necessary to draw up a competent professional project. Designing ventilation for a cottage is a responsible and complex process that is performed by specialized organizations. But if necessary, you can make the project yourself.

How to calculate air exchange in a private house

There must always be a continuous exchange of air in the room. The process is important both in cold and warm seasons.

First of all, this is necessary to maintain sanitary and hygienic standards, to clean the air from dust, dirt, high humidity. In a sealed room, a "conservation effect" occurs, and all microbes and bacteria multiply at an increased rate.

In addition, by means of air exchange, the process of cooling or heating the room can take place.

The peculiarities of the organization of air exchange in the premises are regulated by the Building Norms and Rules (SNiP).

Distinguish between norms for public buildings, apartment buildings, industrial buildings and general norms and requirements.

In residential premises, ventilation is:

with natural air circulation;
with mechanical (including heating function);
mixed.

Oxygen enters the rooms through windows, vents, wall valves. Removal is usually done through hoods in kitchens, bathrooms, washrooms.

Air exchange rate:

up to 30 m 3 / hour per 1 m 2, provided that 1 person has less than 20 m 2 of area;
from 30 m 3 / hour - if more than 20 m 2.

Air penetrates into kitchens in the same way as into living quarters. But the work of the stoves and the steam from cooking make it necessary to organize enhanced natural draft or install hoods.

Norms for the kitchen: from 60 to 100 m 3 / hour.

In bathrooms, air exchange should be from 25 m 3 / hour, since unpleasant odors and chemicals should be removed. In rooms where linen is washed and dried - from 90 m 3 / hour. Air enters through doors and door slits from adjacent rooms.

In office premises, air exchange is from 60 m 3 / hour per person.

The main requirements for the ventilation system in the room can be distinguished:

full supply of fresh air;
noiselessness;
inflow and outflow;
economical consumption of heat and electricity.

Air inflow into the room is carried out in the following ways.

Through loose fences.

The process is called infiltration. It consists in the flow of air through walls, cracks in window frames and doorways.

Airing.

It is produced by opening windows and doors in whole or in part. Depending on the latitude of exchange, the rate of complete air replacement in the room changes: from 3 to 80 minutes.

Built-in infiltration valves.

They are special holes in the window frame through which air from the street enters. In the absence of these, special valves with a plug are used, which are placed either in the wall next to the window or above the radiator to obtain warm air.

Forced ventilation.

We are talking about the use of fans, heaters, filters, noise-insulating elements.

The air exhaust system is of two types:

natural,
mechanical.

The natural system is used when there is no need to remove large volumes of air. Or when a ventilation shaft is provided in the building structure. Mechanical is used in bathrooms, bathrooms, kitchens, that is, where it is necessary to clean large air flows. To do this, use built-in hoods, electric fans.

Organization of ventilation in a private house

Before proceeding with the installation of ventilation in the house, it is necessary to study the advantages and disadvantages of various systems.

The advantages of the natural system include the following:

installation of additional equipment is not required;
no breakdowns, no need for maintenance;
combination with an air conditioner.

The disadvantage is the lack of the ability to control and speed up the process, as well as the need for the presence of wind to function.

Mechanical system advantages:

work does not depend on weather conditions;
cleaning, heating, cooling air;
control of the amount of processed air.

Disadvantages are high installation costs and the need for constant inspection and maintenance.

The choice of ventilation system will depend on whether the house is inertial or inertialess.

Inertia is the property of a house to maintain a given temperature for a certain time. The higher the degree of inertia, the longer the house remains warm when the heating is off. The inertialess house cools down almost immediately.

Inertial houses take a long time to warm up, as they accumulate and store heat. Therefore, in this case, it is better to use natural ventilation, since the circulation of air from the outside will not affect the rapid cooling or heating.

In inertialess houses, it is better to install a mechanical system, since it will be necessary to quickly either heat up or cool the room.

In private houses, it should be borne in mind that the ventilation device for each individual type of room is different from each other.

In living rooms, it is important to ensure the flow of air by opening windows and vents, installing air valves or through slots. Outflow occurs through exhaust vents in bathrooms, bathrooms and kitchens.

In the kitchen, the inflow is provided by windows and adjacent rooms, the outflow is provided by built-in hoods. The same situation is with bathrooms, lavatories, laundry and ironing rooms.

Home ventilation design involves the use of various types of equipment.

Ventilation and savings

The ventilation system must be correctly designed for each individual room, easy to operate and economical in terms of the use of funds and resources.

In the cold season, together with the ventilated air, a large amount of heat is also discharged, which contributes to an increase in thermal energy consumption and increases the cost of utilities. Such a development as a recuperative ventilation system will help to counter this.

A recuperator is a special heat exchanger that receives warm air, conducts it to cold air, mixes the flows, warms up and returns it to the room. Most of the heat does not leave the room, but is cleaned and returned.

Types of recuperators:

lamellar (air flows touch through the plates without mixing with each other);
rotary (heat replacement occurs by means of a rotor);
with an intermediate conductor (tubes, cavities).

The choice of a recuperator model depends on each specific room and financial capabilities.

Benefits of using a recuperation system:

return of heat and energy;
low cost of equipment;
stable functioning;
significant reduction in the cost of heating.

Experience shows that utility costs are reduced significantly. In addition, the workload of the heating system is reduced, the quality of indoor air improves, which has a positive effect on health.

Design and installation of ventilation in a private house

To make a competent ventilation project for a private house, it is better to apply with an order to, which will take into account the norms of SNiP.

If you have specialized knowledge and skills, you can do the design of ventilation in a private house yourself.

Actions:

determine the norms based on the area of \ u200b \ u200bthe premises;
calculate the size of the air ducts;
draw up a diagram of the location of the air ducts;
designate and prepare places for equipment installation;
to carry out installation and construction.

An important point: do not install high-power networks, as this will cause an unreasonable increase in energy costs.

Ventilation is mandatory:

in bathrooms and bathrooms;
in kitchens, pantries, ironing rooms, laundries;
in garages, basements, boiler rooms;
in living rooms far from the ventilation channel.

Tips for economical installation and use of systems.

Insulate the ducts to prevent heat loss and condensation.
Install systems in bathrooms and toilets that work only when the lights are on.
You should not save on materials, it is better to immediately buy high-quality ones, since they should serve for a long time.
To reduce heat energy losses, it is better to install recuperation equipment.

Providing air exchange in a private house is a complex and responsible process. The microclimate, room temperature in winter cold and summer heat, air purity from dust and bacteria will depend on this. It is necessary to choose the places for the air exhaust ducts wisely, to carry out high-quality installation and to take care of saving resources.

Design and installation of ventilation in private houses

We will help you formulate the terms of reference. We will professionally carry out a ventilation project and installation work with subsequent start-up and adjustment. Complex climatic solutions!

Creation of a ventilation system in a cottage or private house

Construction, finishing, engineering. Among all this is the task of creating a heating, ventilation and air conditioning system in a country house. Trust these sections to us!

Professional engineering company "Project Climate" is:

narrow specialization in the segment of air conditioning, ventilation and air quality control systems
assistance in preparing technical specifications for design
development of professional ventilation and air conditioning projects by in-house designers, including the logic of the ventilation, air conditioning and humidification automation system
work on the object only by full-time employees, the allocation of a project manager responsible for all stages
rich experience in the implementation of objects of varying complexity: from multi-room apartments in residential complexes and country houses to industrial facilities
provision of further support and maintenance services

"Project Climate" is a team of professional engineers capable of realizing a project of almost any complexity. Full-time employees, our own service center, site managers, foremen and proven installation teams over the years.

Trusting an indistinct company or "general construction" would be a categorical mistake: the selection and installation of such systems "by eye" can turn, at best, incorrect work (low efficiency, noise, vibration), at worst - complete unsuitability with the need to rework the entire engineering systems. And it is good if this is clarified before the final finishing of the premises.

The remoteness of the cottage does not matter. We carry out work in Moscow and the whole Moscow region. Including many facilities in the surrounding areas.

Ventilation and air conditioning project

We won't even start without a project. And this is not some kind of ultimatum, no: it just won't work. Neither we, nor your builders, designers, specialists in weak currents. There will be mess and confusion at the facility.

You also need a ventilation project, because this is your insurance against:

sudden "extra work" during installation
inconsistency of elements of other engineering systems: existing and created
terms of work

Ventilation and duct air conditioners.

Axonometry of engineering systems.

Supply and exhaust ventilation system project

Project for duct air conditioners.

We are confident in our technical solutions and designers and readily undertake the implementation of projects: in 95% of cases, we also install engineering systems designed by our department.

The project itself will become the basis for further selection of the main equipment: initially - according to characteristics, when specifying the project budget - according to cost. The project will reflect all the necessary consumables required for the installation of ventilation, including a drawing of individually ordered elements for the object - adapters for grilles, adapters for duct air conditioners (namely, they are often combined with a ventilation system), adapters for diffusers, outlets ...

Variants of ventilation systems for a private country house

The variability of creating ventilation systems is endless, everything depends on the features of the object (features of the building itself, utilities) and design delights.

There are three most common schemes for implementing a ventilation system for a country house:

air supply by installing the air handling unit without forced removal of the air medium. In this case, air can be removed from the premises both through the ventilation shaft and through a separate hose using an exhaust fan
supply and forced removal of air by means of an air handling unit. As a rule, such installations have a recuperator, which provides significant savings due to the transfer of heat to the supplied air due to the removed from the premises
ensuring the flow of fresh air into the cottage using a system based on a duct air conditioner. It is difficult to call it full ventilation, but the supply of air from the street (pre-purified and possibly humidified) to the ducts can be ensured

Ventilation system based on the supply unit

During the construction of any house, a ventilation shaft is laid, which provides a natural exhaust of air from the room (if there is an intake from outside). It remains only to calculate the required volume of air supply to the premises. This is exclusively the task of the engineer when creating a project for a ventilation system for a country house.

Taking into account the number of people in the room, the volume of the premises, the parameters of heat input and other parameters, the required air exchange is determined, i.e. the number of cubic meters per hour of air supplied to the room. Taking into account the expected location of equipment and anchor points, the lengths of the air ducts and bends are calculated. Further, taking into account the resistance, filters and heaters, the required equipment is determined, the supply unit itself, capable of supplying a given volume of air to each room.

Installation of a compact supply unit in the attic.

Country house: small ventilation system.

In this case, the air supply unit is responsible for the air supply, which is a monoblock unit that combines all the elements: a filter, automation elements, a fan, sound-insulating materials, a heater. At some facilities, type-setting ventilation is installed, which functionally represents the same supply system, only all the elements are mounted separately (duct fan with a power regulator, a noise muffler built into the system, a duct heater with sensors and a filter), often remotely from each other - it all depends on the specific object, restrictions and goals.

The air squeezed out of the premises is removed through the ventilation shaft. If necessary, fans can be installed that remove air from some rooms (bathrooms, dressing rooms) forcibly. Check valves with or without electric actuators are installed in the air duct system to ensure the overlap of the channels and prevent reversible air supply.

Ventilation system based on the air handling unit

The air handling unit, in addition to supplying air, ensures its removal and forced output to the outside through separately mounted air ducts. Decorative grilles through which fresh air is supplied and existing air removed are installed at a distance from each other, which guarantees good ventilation of the room.

The use of air handling units with a recuperator is gaining increasing popularity due to its efficiency. The recuperator is a plate heat exchanger that allows you to reduce the cost of heating or cooling: the exhaust air transfers a significant part of its heat (up to 85-90%) to the supplied one.

A recuperator in a supply and exhaust ventilation system is a preservation of up to 80-85% of heat. In other words, a significant reduction in heating and air conditioning costs when the ventilation system itself is operating all year round!

But, as a rule, as part of the system, there is still a heater with temperature sensors and regulation of heating power: it allows you to additionally heat the air and prevent the supply of a low temperature air mixture. By the way, in summer, the picture is different: the already cooled air blown out partially cools the supplied air, which reduces the cost of air conditioning the whole house!

Ventilation system based on duct air conditioner

In the overwhelming majority of cases, customers ordering the installation of ventilation systems also install air conditioning systems. Air conditioning in a country house and a cottage can be of different types: the usual wall units, ceiling, floor. But one type has the ability to take in and supply fresh air from the street - these are ducted air conditioners that can also provide completely hidden installation, i.e. without visible communications: only decorative grilles.

The duct air conditioner, although it does not provide a full-fledged inflow, but only mixes (up to 30% of its performance) air outside the building, but still improves its quality, while cooling or heating the room.

Duct air conditioners with fresh air supply: air duct connection.

Establishing a duct with fresh air from the street in the duct air conditioner.

The supply ventilation duct is supplied to the split duct system.

The removal of the surplus can also be realized either by means of an existing air shaft, or forcibly by means of an exhaust fan.

Installation of ventilation systems

Installation of ventilation systems is a complex and responsible process, because most of all units and communications are sewn up and hidden during repairs. It is almost impossible to dismantle, replace, reconfigure after the completion of the repair without partial destruction of the walls or ceiling, and it is also wrong to leave a malfunctioning system: somewhere there will be a lack of inflow, somewhere on the contrary there will be wind blowing, or excessive noise in the channels when the system is working ventilation will not let you fall asleep and rest.

An attempt to involve a non-professional company in this process is fraught with reworking not only the ventilation system in the whole house, but also repairs as such, which is why much attention is paid to the preliminary process of designing ventilation and air conditioning.

But even a little to mount is technically correct and competent. It still needs to be made to work correctly. And effective. All this ultimately affects the economy and reliability: you have been creating a system for more than one year! The automation system is responsible for the management, which can only be created by a professional engineering company! After all, it can include such elements as:

humidification or dehumidification system
carbon dioxide monitoring system
heating of the supplied air during the cold season

Work with professionals! Let's try to start cooperation at least with a call from our manager and drawing up a preliminary commercial proposal.

Types of heating, ventilation and air conditioning (HVAC) systems of a cottage, a frequent country house

Choosing a specific type heating, ventilation and air conditioning (HVAC) systems depends on many factors: there is gas on the site or not, the desired air quality, the customer's financial capabilities, the availability of energy-efficient solutions.

We will reveal the main types of systems used by specialists Detail Engineering.

Type 1. High-temperature heating of a cottage, a private country house, natural ventilation, wall split air conditioning

Heating, ventilation and air conditioning project for the cottage. High temperature heating by a radiator system.

Heating system cottage, private country house works at the expense of a gas boiler, the type of wiring is collector. Pipes made of cross-linked polyethylene of a high degree of cross-linking Pex -a. Radiators or convectors are provided as heating devices. The underfloor heating system is located in the bathrooms and kitchen. Ventilation system natural with valves installed on the windows. Each room of the cottage is equipped with a humidifier and purifier.

This solution is the simplest and most economical. Capital costs are minimal. At the same time, it will be warm in winter and cool in summer.

Type 2. High-temperature heating, supply and exhaust ventilation, duct air conditioning of a cottage, a private country house

Heating, ventilation and air conditioning project for the cottage. Supply and exhaust system with fresh air admixture into ducted air conditioners.

Heating of a cottage, a private country house a gas boiler with the ability to regulate individual circuits: heat supply to ventilation, warm water floor, pool. Design radiators or convectors can be used as heating devices. Ventilation system- mechanical supply and exhaust with central humidification and good filtration. Conditioning cotteja or private country house- channel based on multisplit or VRV systems. Underfloor heating is provided in the bathrooms and kitchen.

Duct air conditioning can be combined with supply ventilation. Such a solution will significantly increase the level of comfort and have a beneficial effect on the design, because in the serviced premises, with proper design and installation ventilation and air conditioning systems (HVAC) of the cottage, private country house the noise level will drop to 20-25 dB. The cost of duct air conditioning, mechanical supply and exhaust ventilation is higher than that of wall-mounted multisplit systems and natural. Also, the system allows you to regulate the temperature and humidity of the premises, to receive air of a higher quality.

Type 3. Hybrid heating, supply and exhaust ventilation, passive air conditioning of a cottage, a private country house

Heating, ventilation and air conditioning project for the cottage. Fan coil passive cooling system

To improve efficiency and reliability heating systems of a cottage, a private country house the installation of two boilers is envisaged: a conventional high-temperature one and a condensing one. The high temperature boiler serves ventilation system private country house, ducted fan coil units, swimming pool. A low-temperature condensing boiler is most effective at low temperatures of the coolant; with the help of an underfloor heating system, we shut off half of the heat losses of the house. Ventilation - mechanical supply and exhaust with a high degree of filtration and central humidification. Air conditioning system of a cottage, a private country house- due to cold water from the well. The cost of this type is approximately the same as the previous one, however design and installation this type is more labor intensive. When air conditioning a large area, the system benefits from both capital and maintenance costs.

Type 4. Energy efficient heating of a cottage, a private country house. Ventilation with recuperation. Air conditioning - duct fan coil units

Heating, ventilation and air conditioning of the cottage. Type 4. Energy efficient system.

If there is no gas on the site, then the optimal design solution for a heating, ventilation and air conditioning (HVAC) system cottage, private country house is the installation of a geothermal heat pump. Warm floors with a minimum installation step cover part of the heat loss of the room. The rest of the heat loss is assimilated using 2 or 4-pipe duct fan coil units. Air supply and intake from the serviced premises is carried out through the air duct network. Temperature control of the cottage is per room, humidity is centralized. Ventilation - supply and exhaust with heat and moisture recovery. This type heating, ventilation and air conditioning systems cottage, private country house is energy efficient and is very common in Epropus. In Russia, with low gas prices, operating costs are approximately equal, therefore, the main advantages over traditional heating, ventilation and air conditioning systems are: safety, unity of heating, ventilation and air conditioning, and the absence of radiators.

Features of heating, ventilation and air conditioning (HVAC) for a cottage, a private country house

When designing engineering systems for heating, ventilation and air conditioning of a cottage, a private country house, it is important to take into account several features:

noise pollution;

From the point of view of noise for a cottage, a private country house, a single HVAC system is optimal, where fresh air is mixed into the ducted air conditioning system. By installing silencers after the supply unit, at the supply and intake of ducted air conditioners, noise pollution can be minimized.

minimal impact on design;

For a private country house, the presence of only two, and sometimes one, decorative lattice in the premises, minimizing the sinks has a beneficial effect on the design.

minimum power consumption;
high level of automation and ease of use.

DetaiL EngineenG develops projects, supplies equipment and materials, installs and commissions systems: heating, ventilation, air conditioning, water supply and sewerage for cottages, private country houses of varying complexity, taking into account the individual characteristics of the object and the personal wishes of the customer.

For a comfortable stay in a cottage, it is important to ensure good air circulation. The ventilation of the cottage has a special scheme and must be developed by qualified specialists. The owners of future housing can be offered several options for the air circulation system - natural, combined and forced. It is important to remember that the design of the cottage and the ventilation system is interconnected, so the process takes place simultaneously.

Types of ventilation for cottages

Natural ventilation saves electricity, but it has some drawbacks. To ensure full air exchange, it is necessary to prepare an outflow system in the form of ventilation ducts. The draft level is achieved only by the corresponding length of these channels, therefore the option is suitable for two-storey buildings and more.

For single-storey houses, it is recommended to choose a combined type of ventilation. In this case, fans are installed at the inlet of the mines - the air flow remains natural, and the exhaust works with the help of fans. For a uniform inflow and outflow of air masses, it is important to correctly select the power of the fans relative to the area of the premises.

Forced ventilation is used if the previous options are ineffective. Filters, fans, valves, coolers and heaters are used to equip the duct network system. The system can work automatically according to preset parameters.

Purpose of ventilation

Modern cottages are built from heat-shielding materials that ensure high tightness, but prevent natural air circulation. The problem can be solved with high-quality ventilation, which provides the following indicators:

creating comfortable living conditions;

fresh air is supplied to all rooms;

vapors and exhaust air are removed;

interior items and housing are preserved;

there is no stagnation of air, moisture does not accumulate;

mold or mildew does not appear;

the air is cleared of disease-causing impurities.

There are structural differences between the ventilation of a cottage and any apartment, so the organization is carried out differently. The differences lie in a simplified filtration system, autonomous equipment can be installed in the cottage, it is enough to correctly place all the elements and the relationship with communications. Specialized rooms require a special ventilation mode.

It is necessary to take into account the special nuances of system design:

frequency of use;

climatic features of the area;

the purpose of all premises;

total area of the structure.

These are important points that must be taken into account in order to create high-quality and highly efficient ventilation in a building.

The basics of natural and forced ventilation

Natural ventilation of a country house is the simplest option. It is based on natural conditions and the use of temperature and pressure differences inside. A natural draft appears, which ensures air circulation, removing waste streams from the building, which are replaced with clean ones. For air intake, special valves are installed in the form of openings with closed grids. They do not create drafts, but provide the necessary air flow. These valves can close if it is very cold outside. Additionally, they can be equipped with filters, humidity sensors and sound attenuators, and can work in automatic mode.

Waste masses are removed by a system of pipes, outlet openings are placed in the most polluted rooms. The air is removed by means of a draft, for which the pipe outlet is placed at a height of at least 0.7 m above the roof, the hole is covered with an “umbrella” that protects the system from the ingress of sediment, debris, small animals and birds.

Such a system has its advantages:

low cost;

noiseless functioning;

no costs during operation;

simple installation.

The disadvantages of the system are dependence on weather conditions, heat loss in the cold season, lack of control of the outgoing and incoming masses, inefficiency if there is a pool or sauna in the cottage.

In case of ineffective or inappropriate ventilation, a forced type is used, for which high-tech equipment is used:

filters, fans, valves;

air coolers and heaters;

duct network.

The system simultaneously brings clean air into the house at a comfortable temperature and removes the already exhausted air. The parameters can be set in advance, which allows the system to work automatically. The installation of the system is carried out with the installation of the ventilation unit inside the room. The air ducts are laid with the installation of all components, the system is being prepared for operation. The installation of equipment in each case is considered individually, the placement of the unit, components and air duct is agreed with the customer. The most economical and technologically advanced option is a supply and exhaust ventilation system with a recuperator. A special recuperator takes heat from the removed heated air, and then heats up fresh air coming from the street.

This is an effective method of airing premises; the operation of the system does not depend on various natural factors. But the system itself is quite complex, so appropriate specialists should develop it. It is important to develop a competent wiring of all highways, diameter and length, to pick up all the elements. Periodic maintenance is required, but this allows us to provide a favorable and comfortable living environment with a full guarantee.

Ventilation design

Any project for future ventilation is carried out with the obligatory consideration of the air exchange rates for each individual room and in general for the entire building. In accordance with the norms and requirements, air exchange must comply with the following indicators:

room 3 m 3 / h for each 1 m 2 of living quarters;

bathroom, lavatory, shower room 25 m 3 / h;

combined room 50 m 3 / h, 25.

The parameters are indicated for the temperature in the cold season, the temperature inside the room is 16-25 ° C.

The cottage ventilation project is developed by specialists at the stage of building design. For this, a technical assignment is drawn up, it takes into account the following points:

building architecture;

number and function of rooms;

area of premises;

additional objects that affect the movement of air;

the number of permanent residents.

The calculations determine the capacity of the system for each room separately and for the entire building as a whole. This parameter depends on the rate of air exchange of rooms and the maximum number of people in one room.

The proper functioning of ventilation is given special attention when designing smart home systems. Source restate.ru

After the creation of the project, the installation of ventilation can be carried out, on which only specialists should also work. The process itself takes place in several stages - the preparation of the scheme and the project of the house. In this case, all other communications and systems must be taken into account. Installation and design of ventilation in country houses is a rather complicated procedure and mistakes cannot be made here. Otherwise, they will not be able to meet their goals. For example, a ventilation system requires preparatory actions:

determination of the power of electric networks, their laying and possible reduction of energy consumption;

the ability to install special equipment, as well as the arrangement of air ducts;

selection of equipment taking into account the characteristics of the premises and operating conditions;

installation of all selected equipment.

Conclusion

Professional ventilation will make living in a cottage safe and comfortable. The system will constantly function for the benefit of the person.

Using modern equipment, you can control the flow of fresh air or set the system to operate in automatic mode.

Such systems allow you to make your stay as comfortable as possible at any time of the year and in a variety of weather conditions. In addition, a high-quality ventilation system allows the air to be purified from pathogens and microorganisms. This is a very important indicator, especially if there is a small child in the house. The correct calculation of ventilation is a rather difficult task, the solution of which must be dealt with by professionals.
