The operation of the electrical circuit of the air conditioner. Device and Principle of operation of the Split System Software Scheme Single System Systems

After installation, the air conditioner is connected to the electrical outlet, which is carried out according to the schemes specified both in the internal and external blocks. A detailed description of the stages of this process and the requirements for the mains are usually given in the instructions separately for each device depending on its power.

It should be borne in mind that the electrical circuits of connecting the air conditioner for low-power household and more powerful semi-industrial (commercial) models differ. The first are single-phase, and the second as one-phase and three-phase connection.

There are two methods for washing the split-system: directly through the outlet and by summing up the wire to the electrical tailor. The first option is suitable for household appliances and in case of completed repair indoor. The second method is acceptable for powerful aggregates, as well as for devices of various power at the initial stage of rough repairs. Household models are more likely to be commissioned in the first way, so it will be considered in more detail that it will be more detailed.

As a rule, the wovening of the split system takes place in several stages, which should be strictly followed if the user plans to perform it independently. So how to connect the air conditioner with your own hands without appropriate experience? It is difficult, but quite feasible.

Sequence of work

First of all, the owner of the Split system is obliged to remember the sequence of work. They are held according to such a scheme:

preparation of materials and tools;
study of the air conditioning connection schemes;
laying of inter-block cables - connecting them to the terminals of the internal and external blocks of air conditioner;
connecting the device to the network;
check the parameters of the operation of both modules.

Depending on the internal device, the cable can pass from both the outdoor and room block to the power supply.

Connection and connection of air conditioner inter-block cables

If it is decided to connect the air conditioner to the power grid through the outlet, then you need to make sure that it will endure the upcoming load. If the required parameters are not compliance, the installer should not connect the device to it and must explain to the customer the essence of the problem, as well as offer the output from the position - laying a separate line to the shield.

Here are the basic requirements for the outlet:

The socket must have a grounding or differential relay;
It must comply with the required values \u200b\u200bspecified in the instructions for the split system. The best ratio is the high power of the network and the low power of the cooling device;
Air conditioning is not placed on one line with other powerful devices;
It is forbidden to power the device from the socket if an aluminum wiring is used. To connect the air conditioner through it it is necessary to take a copper wire with the corresponding cross section area;
It is important to make sure that the socket itself is connected through an automatic, which has a distance between contacts of at least 3 mm in an open state;
The work performs only an experienced installer in accordance with the required state and local standards.

Under all the listed requirements, it is embarked on preparatory work on connecting the air conditioner to the outlet with their own hands. First check the presence of the desired tools, and then clean the cable veins with a knife or device for removing isolation. Now switch to the laying of inter-block cables and connect the external unit of the air conditioner, and then internal.

Modern reinforced Euroresets are usually suitable for high-power devices.

The connection is carried out according to the circuits on the blocks on which the terminal blocks corresponding to inter-block cables are indicated. Unconnected cable veins are required to isolate so that they do not come into contact with the current-friendly parts of the air conditioner.

Marking terminals for ON / OFF models of split systems:

1 - power supply compressor;
2 (n) - general neutral;
3 - four-way valve;
4 - fan of the external block;
(land).

Marking of terminals for inverter models of split systems:

1 - nutrition;
2 (n) - neutral;
3 - management;
(land).

In some Chinese economy class aircraft, a separate wire is laid for connecting the temperature sensor.

Wires are connected to terminals. Box with terminals is under the blocks panel. In accordance with the numbering of the wire of the internal module, connect with external contacts.

Stages

Brief Instructions for connecting the air conditioner with your own hands for the inner unit as follows:

Remove the decorative panel from the block.
Remove the protective cover from the connectors and the cord lock.
Put the inter-block cable through the mounting hole in the back of the device.
Prepare the cable to connect, after reading it and removing the insulation.
The stripped ends are inserted into the terminals and tightly tighten with screws. Mustache efforts should be approximately 1.2 nm. Usually, screw clamps are used in terminal pads to connect wires.
The locks are well fixed by the inter-block wire.
Install the terminal cover.

The same brief instruction is suitable for connecting an external unit of the air conditioner by electrical circuit yourself. Instead of the decorative panel, the outer block remove the protective cover and connect it with wires with an internal module through the terminals.

At the very end, they check whether the operation has been done by the connection schemes. Only then you can turn on the device.

Selection Wires for Connection

It is worth remembering what the wire is necessary for connecting the air conditioner, or rather what section is required. Its parameters are indicated in the instructions for each model of the split system individually. The section depends on the power of the device. As a rule, household air conditioners (7, 9, 12, 13 sizes) require a wire diameter from 1.5 to 2.5 mm². Current can be focused: less than 18 A - 1.5 mm², more than 18 A - 2.5 mm².

Also, the wire required for connecting the air conditioner to the electrical outlet is chosen, given the remoteness of the shield. The distance between the instrument unit and the electric shield over 10 meters requires the section from 2.5 mm².

In order to ensure reliable operation of the air conditioner, only copper wires use. For a single-phase connection, a three-core wires (phase-zero-land) are taken, and for three-phase - five-housing.

The wire cannot be laid near gas and heating pipes. The minimum distance between them is at least 1 meter. If necessary, use additional insulation. As a rule, the cable is paved together with the highway in the corrugation and hide in the box or the stroke in the wall.

Cable walls are attached to clamps that are fixed with dowels or screws. When placing communications in the box for their mounting, glue or screws are used. If a hidden wiring is performed, the wires are hiding in the corrugation and fix it to the wall using special clamps.

Circuit breaker

If you plan to power the split system from the panel, then you will need protection devices by one of which is the circuit breaker. It is selected regarding the rated power of the device specified in the technical passport or on the external block. It is advisable to always leave a small stock. For example, start-stop air conditioners have a very high starting current, excavating for 20 A. and although the duration of work is small at such values, after all, it is worth considering it.

You can choose the necessary values \u200b\u200bof the current automaton by the formula: the air conditioner power (kW) is divided into network voltage (220 V) and increase the data obtained by 20-30%.

When connecting the air conditioner to the supply network, it is important to remember that the circuit breaker must have a distance between the contacts in the open state of at least 3 mm for each phase wire. Strictly observe the phase: the phase connection procedure must correspond to the order on the terminal block.

For air conditioners, a circuit breaker of type C is fits. It fully ensures the safety of the engine load and has high response characteristics in the event of an emergency situation.

You need to make sure whether the electrical stopper allows additional equipment to it.

It is worth remembering that both the air conditioner and other household electrical appliances are most reliable to connect through a separate line. With this option, it is not necessary to install a protective shutdown device and a differential relay.

What information can be found in the manual service (instructions)
Service Manual (instruction) contains information related to the maintenance and small repair of a particular equipment. As a rule, you get the service manual for your device when purchasing it. In addition, today there are many Internet resources providing instructions for devices of various models and brands.

What is the scheme?
Schemes and schematic diagrams are an integral part of the electrical industry, as they are a visual description of the designs of certain devices. Schemes are necessary for maintenance and repair of various equipment and electromechanical systems.

Use of manuals (instructions) for repair.
Manuals (instructions) for repair for one or another device are usually issued by independent publishers that are not related to official equipment manufacturers. These are not the instructions that are initially supplied with the acquired technique. Although in general, the information contained in the repair manuals is similar to that which can be found in the usual instruction, there are clear differences between these documents. The fact is that repair manuals provide us with more detailed, full and specific information.

Is it possible to make a connection without attracting specialists and how to do everything?

The main difficulties in my opinion occur when connecting the outer and internal blocks with copper tubes (buying these tubes (I have not met them anywhere in the markets. Maybe I did not carefully search) and their collapse).

Maybe they still missed the highlights, I think in the process of discussion to the whole world CO-form what to install air conditioning.

By the way, I forgot to say the Condishn of the company LG G07LH will be installed in the living room with an area of \u200b\u200b15m2, the outer block will be delivered only to the loggia (because 2nd floor is the possibility of its theft).

It seems to be everything, where to start, probably with the purchase of the necessary additional comlarders:

1. Wire EL. cross section 1.5mm2;

2. Copper tube 3.8 / ќ (for compounding a refrigerant) (diameter 9.52) - I have not met anywhere in the markets;

3. Copper tube 1.4 / ќ (for condensation compound) (diameter 6.35) - I have not met in markets nowhere;

4. Rubber pipes for placing copper tubes (used as isol-tori);

5. Vinyl tag;

6. Pipe with tube (for installation in the wall);

11. Fork for connecting to email. Outlet.

Video instruction "Installing an air conditioner from LG"

Description:
Video instruction "Installing an air conditioner from LG" is represented by R410.com.ua

Air conditioners are the most demanded technique in the hot period of the year. That is why they are widely used in offices, houses, apartments, etc. Air conditioning systems are characterized by the complexity of the installation, so users often seek help from specialists. If you understand the scheme, you can connect.

Installation of the indoor and outdoor unit

In order to ensure a high level of operability of air conditioning systems, it is important to correctly install internal and outdoor blocks. Installation of the indoor unit is carried out on special plates that are supplied complete.

Fastening the mounting plate is made at the installation site of the internal unit of the air conditioning system. In order to ensure reliable operation of the block and prevent condensate leakage, it is necessary to secure the plates correctly. Initially, there are places of holes in the plate on the wall and with the help of the perforator drill holes. They use the dowels. The mounting plate is attached to the wall by screwing the screws in a dowel. The final stage is to install the inner block on the plate.

Installation of the outdoor unit is made from the outside of the building. To ensure convenience when servicing it, the mount is made on the side of the window or under it. Connecting an outdoor unit of the air conditioner is made using a special device that comes in the kit.

IMPORTANT! In order to ensure efficient block operation, an installation is made at a distance of 10 centimeters from the wall.

Features of connecting the route

Many people ask how to connect the air conditioner with their own hands. Perform yourself quite simple - just need to know the air conditioner connection scheme. There is an important role in it, which consists of:

drainage pipeline;
power wires;
equipment management;
freon highway.

Connecting the air conditioner to the power grid requires measurement of the length of Trasi. 30-50 centimeters are added to this indicator. Initially, copper tubes are made, which are cut with a pipe cut.

Attention! When laying copper tubes, apply a hacksaw or a grinder to cut them categorically forbidden. This is explained by the fact that in the process of cutting with such tools, the chips occurs, the hit of which in the air conditioning system leads to its breakdown.

Connecting the air conditioner requires room to be placed in a thermal insulation shell of pipelines before installation, and the holes are closed by plugs to eliminate the possibility of penetrating the inside of dust. All components of the tracks are folded together and fasten with vinyl tape. Next, the installation of the route is made.

After the communications are laid, it is processed to connect the freon highway and electrical wiring. You can independently connect the air conditioner to the power grid - the scheme is included in the kit. It shows in detail the way to connect the air conditioner to the power grid.

IMPORTANT! When installing the electrical system, you need all actions to perform strictly according to the scheme. Otherwise, the air conditioner can burn at the first turn on the short circuit.

The next installation stage is the adjustment of the length of the tubes and the removal of bursts. To this end, the rime is used. The nut do and fragile each edge of the tubes. Then, connect the edges of the tubes to the fittings of the inner and outer block. With the help of a dynamometric key, we highly tighten the nuts.

A WARNING! If the nuts are not tightened enough, they will unscrew a little over time, which will negatively affect the operation of the air conditioning system.

After connecting the route, it is checked for its tightness. The video can be found with tightness checking technology. Next produce moisture and air removal from the system. For this purpose, a vacuum pump is used. Connect it to the service port of the outdoor unit through a manometric corrector. Pumping air and moisture should be carried out for half an hour. The next step is the filling of the contour by Freon.

A warning! In the absence of the tightness of the track, freon leakage can occur - a frequent reason for breakage of air conditioning systems. Connection diagram of the air conditioner compressor will show how to hermetically combined the track.

Features of connecting compressors

Consider in detail how to connect the compressor from the air conditioner BC 1500. Connection is made with regard to:

characteristics of the compressor itself;
used voltage air conditioning system;
air conditioning power systems.

The air conditioning system compressor is started in a few seconds.

Scheme of work

Connecting the air conditioner compressor is a simple task. Any of two compressor outputs are connected to the power supply. The terminal is connected from the third exit. Wiring is connected to the second output. Complete the compressor connection, check the level of its performance. For this, the air conditioning system is activated for several minutes and the degree of heating of the compressor is determined.

Attention! If the compressor heats up strongly and quickly, then it speaks of bad work of wiring. To correct problems, it is changed by places at the outlet of the compressor.

Automotive air conditioning systems have difference from stationary. Therefore, when installing it, the Panasonic air conditioner is used to Lada Grant. The correct connection of air conditioning systems in the vehicle will guarantee it excellent performance.

An example of connecting air conditioning systems

Mobile air conditioner connection is performed in the same sequence as stationary. Connecting to the mains with their own hands is made in several stages. Initially, an electrical panel is set to install a separate automaton designed for air conditioner. Next, connecting the phase wire of a three-core cable having a black or brown color to the phase terminal of the machine. The blue cable wire is connected to the zero tire of the electrical panel. To the grounding wire of electrical wiring is made fastening the yellow-green wire, if available.

IMPORTANT! Connecting electrical wiring should be carried out correctly. Otherwise, you can bring the air conditioning system to a serious breakage or complete failure.

In the absence of grounding, the differential relay is used to protect against electric shock. If you do not know how to connect the air conditioner with your own hands, you will tell you the video about it. With it, you can also learn about the features of the connection of the diffuse relay.

If you want to know how to connect the floor conditioner, then you need to initially install its inner block. For this purpose, a three-phase cable with three wiring of different color is used:

black;
blue;
green.

Sometimes the color of one wiring can be yellow-green. The air conditioner connection power circuit will tell in detail about the installation of the indoor unit. The wire characterized by the presence of a black braid and is connected from the machine to the L-terminal. Wires running from a shield and having blue color connected to the N-terminal. In the internal unit of the device, the wiring of yellow-green coloring to the terminal mass is connected. Connection diagram of Calina air conditioner shows exactly the same installation of air conditioning systems.

Attention! Connecting an external block of air conditioning systems is made according to the same scheme. When installing the outer block, the wiring is used with a cross section - 3x2.5 millimeters.

The output machine is set to the load current in the electric shield. When installing electrical wiring, special tubes are used. If the electrical wiring is laid along with the drainage or near the freon sites, then the corrugated tube is used.

Connect the air conditioning system with your own hands is quite possible. To do this, you need to explore the instructions and all actions to perform in strict accordance with it.

Any air conditioner consists of two different parts of the parts: a refrigeration circuit that performs the air cooling function and the electrical part, controlling devices and contour elements.

This article will consider the electrical circuit of the air conditioner, the options for connecting it to the power supply and how to connect the air conditioner to the power grid.

What is the electrical scheme of the split system

The electrical circuit of the air conditioner is a document in which the location of electronic components is displayed, their connection, as well as information for service centers engineers. All who are more interested in the electrical circuit of connecting the air conditioner, which includes the location of the main devices of the evaporative and condenser block, terminals for connecting blocks between themselves and connecting the power supply.

The main elements here are:

Compressor, with CSR conclusions. The arrow shows the protection installed on the compressor winding
Compressorcapacitor is a condenser, two conclusions are connected to the windings of the compressor unit. The third condenser output is connected to its launcher.
In addition, the fan motor and condenser is indicated on the diagram through which the two windings of the electric motor are connected.
The scheme indicates an electromagnet managing the operation of the four-way valve.

Designations of terminals in the terminal block:

1 (N) - zero.

3 - Power supply to the fan motor when working in small turns.

4 - power supply on the fan motor when it works at elevated circulation.

Separate terminal - Earth.
Main modules and blocks:

The power filter through which the voltage is supplied to the control board.
Control Board - control unit to which all device modules are connected.
The power relay of the compressor power relay is connected to CN 12.
The drainage pump is connected to CN6.
CN 5 terminal bar is responsible for controlling the split system fan.
Conclusions of CN 10 are connected by a stepper motor control grid control.
CN 7 conclusions are responsible for connecting the heat exchanger temperature sensor.
The terminal temperature of the CN15 is connected to the conclusions 1 and 2 of the CN15 terminal.
To the conclusion M 1 and 3 terminal cable CN15 connects the water level sensor in the pallet.
Terminal CN 13 of the control unit is responsible for connecting the device indication unit.

Terminal (on the board is indicated by Terminal) for connecting the cable of evaporative and condenser blocks. Terms L and N - power conditioner from El. Transmissions. You should know that there is a connection of the air conditioner to the electrical outlet through the external block.

With such a connection, you must be guided by the instruction. If the climatic equipment is connected with a power up to 4, 5 kW, the four-tier copper cable with a cross section of 2.5 mm 2 should be used. With a separate power branch, a capacity of 20 A. is required to be installed on the shield.

Connecting conditioner

After them, it is necessary to connect with each other a four-core copper cable with a cross-section area of \u200b\u200bat least 2.5 mm 2. The connection instruction is the schematic diagram, which was considered sufficiently detailed above. The connecting cable can be paved together with the freon highway, and maybe in a separate plastic box.

When laying in one stroke, along with copper tubes, use a corrugated plastic tube for insulation cable.

After the inter-block electrical connection, connect the internal unit to the power supply. Diagram Connecting an air conditioner to the power grid assumesing food, both from the nearest outlet and from a separate line.

An ideal option for connecting enough powerful climate machinery is a separate power line. Such an option will not load the existing lines of the apartment electrical system and will allow power to be powered directly to the inner block of the split system. The power cable gasket from the panel to the indoor unit can be performed on the stroke groove in the wall material or in a special plastic box.

The shield from which the individual power line must be grounded. Connecting the power cable to the terminal shield should be carried out only through an automatic, the power of which should be calculated by the formula: the power of the device is divided into voltage. Add 30% of the reserve to the resulting value.

It should be understood that the power cable of the climate technique can be tested to the outlet only if:

Climatic equipment has a small power.
The domestic power grid is laid with a copper cable with a cross section of at least 2, 5 mm 2.
There are no energy-intensive consumers on one air conditioning branch.
It is assumed temporary.
This electricity branch is equipped with an automatic with an UzO of at least 20 A.

Conditioning options for existing electrolyneys

This question could not be considered, due to the presence of outlets in the room. But, some owners of low-power climatic equipment are dissatisfied with the spent wire from the outlet to the consumer, often across the wall.

If the socket is far enough from the air conditioner, then there is an air conditioner connection option to a power circuit with a switch. I warn you right away: this option is suitable only for low-power climate techniques and this is why: the terminals of the ordinary switch can simply not withstand the current passing through them. As a result, heating, sparking, failover failure (at best) or fire.

Better from the acting socket to label the groove in the wall and pave the power cable in the corrugation to the split system along it, and then build a special outlet with a decorative lining into the wall. The socket must withstand a certain current: if 1 kW is a power, then the socket must withstand 9-10 A; from 1 to 3 kW - 16-18 A; from 3 to 4.6 kW - 20 A; From 4.6 to 5.5 - at least 25 A. The right choice is best trusted by a qualified electrician.

If you decide to connect the air conditioner with your own hands, then do it in compliance with all the safety rules, and in order to completely be sure that the connection process has passed correctly and safely for climate technology and dwelling inhabitants, please contact professionals for help.
