Radiator counters-distributors, individual accounting. Heat metering with apartment distributors Heat meter for apartment indiv 5

counter distributor Indiv 5R Danfoss comes with a reader unit with an installed radio module that operates at an authorized frequency of 868.95 MHz. This system is used for wireless access to the meter and for remote transmission of accumulated readings to network nodes in INDIV AMR automated measuring radio systems. The distributor device determines the percentage of the total heat energy consumed by the house, measured through the collective general house heat meter, attributable to a specific radiator.

The principle of counting readings is the distribution of the general building processed heat energy based on the readings of individual metering devices installed on separate radiators.

The INDIV 5R distributor meter is easy to install as it has a compact size and a universal mount. Installs on almost any type heating systems. Various mounting kits are available for attaching the distributor. During installation, the case is fixed to the mounting plate of the thermal adapter using a special latch seal, which prevents unauthorized access to the device and fasteners.

It collects consumption readings in several stages, starting from the last control date up to the indication of the worked coefficient for the year. Continuous testing to ensure ease of use with storage and transmission of error messages. Displays the checksum of the results, both current and for a specific day.

Heat distributors are still not widely used in our country, although in Europe they are used in industrial scale, since the 70s, and the number of installed heat distributors is in the tens of millions. We do not yet produce these devices, although we already have experience in their use.

The principle of operation of distributors.

The photo shows a thermostatic regulator and a radiator installed in the apartment. The distributor every 3-4 minutes measures the surface temperature of the radiator at one specific point and records the temperature difference between the surface of the radiator and the air in the room into a non-volatile memory. As a result, heat corresponds to the amount of heat given off by the radiator over the past period, measured in conventional units. It is conditional, the readings of the heat distributor during recalculation are multiplied by radiator coefficient, corresponding this type and size heater.

At the same temperature on the surface of a large and small radiator and at the same temperature in the room, the readings of the distributors will be the same, but will a large heater give off more heat? To take this situation into account, the radiator coefficient is used. Each manufacturer has tables of radiator coefficients for their devices for all types of manufactured radiators. Radiator coefficient tables include computer programs for the recalculation of payments, and the coefficients are automatically taken into account in the calculation.

But what about our homemade radiators or battery assemblies, when the residents themselves add sections to the existing radiator, while some of them practically do not heat. There is only one conclusion, you will have to get rid of homemade products.

The cost of a heat distributor and payment for heat.

The cost of a heat distributor is about 10 times less than the cost of an apartment heat meter. Distributors are easily installed on any type of heating devices. This is the main advantage. Due to this, the cost of a set of devices for an apartment is acceptable even if there are several risers in the apartment.

Heat distributors are suitable for all heating systems.

Calculation of payment for heating according to the readings of the heat distributors is the distribution of the total amount paid to the heat supplier between individual apartments in proportion to the readings of the radiator distributors. At the same time, the residents of the apartments monthly, during the year, make payments at fixed pre-calculated and approved rates, and settlements with the heat energy supplier are made according to

Once or twice a year, readings are taken in apartments, and the total amount is distributed according to the readings received. For each tenant, a balance is drawn between the amount of his payments at provisional rates and his estimated payment. The amount received is used to offset payments for heating for the next year.

Thus, in the presence of any type of individual heat metering devices, payments for heating are made dependent on actual heat consumption in apartments.

Finally, let's compare the costs of installing radiator thermostats and heat distributors.

Equipment and costs, Price per piece (at the rate of $ 1 - 60 rubles)

• Distribution sensor for individual metering INDIV-3 with visual reading from the LCD display
• Sensor-distributor for individual accounting INDIV-3R with remote wireless data transmission (radio)
• Installing a thermostat and measuring sensor
• Annual apartment settlement services

In the table, the costs for the installation of radiator thermostats and heat distributors

Calibration interval of heat distributors is 10 years. Apartment heat meters- 5 years.

The payback period for installing heat distributors and radiator thermostats for two-room apartment 1 year, with a service life of a thermostat of 30 years, and a heat distributor of 10 years. For economical residents, this period will be even shorter.

Remember the basic rules for organizing apartment accounting using heat distributors:

• on heating appliances without fail thermostatic controls must be installed.
• At least 75% of the heated premises must be equipped with thermostats and heat distributors in the building.
• the actual cost of thermal energy for heating a residential building should be made by a common house heat meter.
• in the housing organization, recalculations of payments for residents should be organized according to the readings of common house and apartment meters.

Counter Indiv 5 and its improved modification Indiv 5r is radiator distributors, allowing to organize heat accounting for each separate apartment. These devices are intended for buildings with vertical wiring heating, that is, for almost all modern multi-storey buildings.

Operating principle

The Indiv 5 heat meter measures and registers the temperature difference between the radiator and the air in the room. The temperature sensor is built into the Danfoss Indiv 5 case. The air temperature is programmed as a constant value of 20° C. This averaging introduces a certain error in the readings of the Danfoss Indiv 5, however, this is not such a serious problem. But the rest of the calculations will be made with maximum accuracy, even if the Indiv 5 distributor meter is covered with thermal insulation.

The data is displayed on the LCD screen. With how to take readings of Indiv 5, there will be no problems even for a person who is far from technology. The monitor alternately displays:

• up-to-date information;
• data on the results of the previous time period;
• end date of the current Danfoss Indiv 5r cycle;
• calibration factor;
• checksum, etc.

All calculations are automatically carried out software AMR provided to the management company that owns the house.

Installing a Danfoss heat meter on a radiator is not very difficult. The device is attached to the surface heating equipment using the mounting kit. It is important to strictly adhere to the Indiv 5 manufacturer's instructions regarding installation rules for specific devices. Sometimes a situation arises when it is not possible to fix the radiator meter distributor Indiv 5 on the surface of the battery. In such cases, you will have to install a remote sensor with a connecting cable and turn off the built-in one. This solution is usually intended for units with a casing.

The price of the Indiv 5 dispenser installed on the counter will not hit your budget too hard. However, it is worth purchasing a device only when the housing company has organized an appropriate recalculation according to the readings of individual and common house metering devices. To do this, it is necessary that such regulators and distributors stand in at least half of the apartments. If you are interested in where to buy Indiv 5r in Moscow and other useful information equipment, we are waiting for you on our website.
