Design solution of the block heating unit HCU
Reneco has developed a design solution for a block heating unit HCU, which is designed for a residential building heating system from the city's heating network using an independent scheme for 250-300 kW. Features of such a HCU:
- a finished product that is placed on a frame and is ready for installation at the facility;
- two heat exchangers operating in parallel at 50% capacity each for partial redundancy. The heating system will be able to maintain heat during the heating season in case of failure of one of the heat exchangers;
- frequency-controlled pumps are used - one working, the other backup, the use of which provides for reduced power consumption and flexible operation in the heating system;
- a control panel that includes a weather controller, which allows the temperature of the heating medium to be adjusted depending on the outside air temperature. This significantly reduces heat consumption;
- built-in dry-running protection of the pumps;
- the heating system is powered by the city's heating network;
- recharge in case of leaks;
- the possibility of dispatching and remote monitoring.
- outdoor air temperature;
- outlet and return temperature of the coolant pipeline;
- pump failure;
- heating system coolant pressure below normal.
- heat carrier pressure in the residential building heating system;
- heat carrier pressure in the city heating network supplied to the residential building.
