The Heat Center consists of: Two 157kW condensing gas boilers providing Tinst 45/40 °C, 115kW air-to-water heat pump at 40% glycol with Tinst 50/40 °C (winter) and Tinst 5 / 10 °С (summer ). The heat pump unit is designed to operate on heating in the transition seasons. Plate heat exchanger Glycol / Water divides the outside of the installation into the chiller from the inside of the installation to the building. (Tinst 45 / 40 °C (Winter) and Tinst 7 / 12 °C (summer), Buffer vessel ensures the operation of the system, preventing frequent start-up of the heat pump stops Water collector and water collector, radiators Fan heaters and hot air heaters. an automatic circulation pump is used to control all circulating pumps and actuators of the three-way valves.The electronic circulation pump performs the movement of the fluid in the heat pump-heat exchanger circle and another in the circulating heat exchanger buffer tank. is fitted with a safety valve, an expansion tank before and after the buffer vessel, a stop valve and a measuring fitting.

For the winter mode of operation, the heat carrier is supplied by the water-cooled boilers with parameters 45 / 40 °С to the internal heating system. The system is two-pipe and the switching from one mode to another is manually by switching the shut-off valve.

The collector is equipped with circulating pumps delivering heat transfer to the individual circles, namely: one circle feeds all consumers who operate in summer cooling operation mode, another circuit feeds pounds for the sanitary premises and the DHW cylinder, and the third one supplies a heat carrier to Air Heaters in a service area.

Circulation pumps, required stop and regulating fittings, filter and return valve are provided on the risers. The fluid is distributed to the consumers through Large Diameters Steel Welded Tubes and Galvanized Pressure Tubes for Smaller Diameters - according to the diagram. Automatic deaerators, drain faucets are provided.

The Ventilation Recuperative Blocks are complete with a heat exchanger section for the outlet in the air duct complete with a drop trap.

A server room is provided with a separate air conditioning split system that will be set to automatic temperature mode and equal annual temperature. Its outer body is located near the wall thermo-panel with a louvre grid and separated from the inside air by a barrier. The indoor unit is for high-wall installation.
