Radiator counters-distributors, individual accounting. Radiator meters-distributors, individual metering Kit for mounting the meter-distributor on cast-iron sectional radiators

The Indiv 5 meter and its improved modification Indiv 5r are radiator distributors that allow you to organize heat metering for each individual apartment. These devices are intended for buildings with vertical heating distribution, 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 by the AMR software provided by the management company on whose balance sheet the house is located.

Installing a Danfoss heat meter on a radiator is not very difficult. The device is mounted on the surface of the heating equipment using a 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 on equipment, we are waiting for you on our website.

Devices for the distribution of thermal energy electronic INDIV-5, INDIV-5R, INDIV-5R-1 are designed to measure the temperature of a heat-receiving metal plate fixed on the surface of a heater and present the measurement result as a cumulative total in the form of an integral over time (formula /1/), proportional to the heat energy supplied by the heating device.

Description

The principle of operation of devices for distributing electronic thermal energy INDIV-5, INDIV-5R, INDIV-5R-1 is based on measuring the temperature tm of a heat-receiving metal plate fixed on the surface of the heater. The measured temperature is used to calculate the temperature difference At =(tm - 20) °C and calculate the time integral. The device displays the obtained dimensionless integral value, on the basis of which the relative share of the heat transfer of this heater in the collective heating system can be calculated. Electronic heat distribution devices INDIV-5, INDIV-5R, INDIV-5R-1 are shown in Figure 1. All modifications have an identical appearance.

Picture 1.

The design of devices for distributing electronic heat energy INDIV-5, INDIV-5R, INDIV-5R-1 is a non-separable plastic case with a transparent display window on the front wall. The temperature sensor is located either inside the housing near the rear wall and is connected to a heat conductor, which is pressed against a heat-receiving aluminum alloy metal plate during installation, or on a fastening washer of a remote cable 1.5 or 2.5 m long. The heat-receiving metal plate is equipped with holes for fastening to heater surface. Versions INDIV-5R and INDIV-5R-1 have a built-in radio module (transmitter) for transferring recorded data to the system radio network via unidirectional radio communication (wireless M-Bus compatible with EN 13757-3 and EN 13757-4 standards). Versions INDIV-5R and INDIV-5R-1 differ in the composition of the mounting kit.

Devices for the distribution of thermal energy electronic INDIV-5, INDIV-5R, INDIV-5R-1 include a power source and a microprocessor with a quartz oscillator that measures the resistance of the temperature sensor, the necessary calculations and control of the alphanumeric liquid crystal display.

Time in hours.

Special mounting kits are provided for fixing electronic heat distribution devices INDIV-5, INDIV-5R, INDIV-5R-1 with an internal thermometer on heaters of various designs. During installation, the housing is fixed on a heat-receiving metal plate with a special seal-latch, which excludes unauthorized access to the distributor's organs and fastening elements. The remote thermometer washer is attached to the heater with a screw and closed with a protective cover, and the housing is installed on the wall of the room.

The display of the device in the measurement mode performs an automatic change of readings and displays the following values ​​(in brackets, the duration of the indication in seconds is indicated):

Current slew rate of displayed sample (2 s)

Display test (all included) (0.5 s)

Display test (all off) (0.5 s)
