Opis

The heat supply system adopted a two-circuit, divided into boiler and network circuits. To separate the circuits, plate heat exchangers RIDAN HHN113-345-TKTM1 on the heating circuit and HHN22-177-TKTM16 on the hot water circuit are provided.
In the boiler circuit, the temperature of the heating water is 110 ° C. Boiler circuit pumps are provided individually for each boiler Wilo IL 100/145-11/2. Three-way valves HFE3 f. "Danfoss" are provided in front of the pumps to ensure a temperature at the boiler inlet not lower than 70 ° C. To protect boilers from thermal expansion, expansion membrane tanks with a volume of 1000 liters are provided in the boiler circuit.
Temperature graph of the heat network 95/70°C. Pumps of the network heating circuit - NL125/200-75-2-12 - 4 pcs (one is a backup). Network pumps with frequency control, maintain a constant pressure at the outlet of the boiler room. Circulating pumps of the DHW network circuit Wilo IL 40/160-4/2 - 2 pcs (one - backup), DHW circulation pumps with frequency control, maintain a constant pressure drop in the supply and circulation pipelines of the DHW network. To regulate the temperature of the mains water, three-way control valves are provided. "Danfoss": - rotary type HFE3 for regulating the temperature of water in the DHW network and saddle type VF3, installed on the supply pipeline of the boiler circuit. Gotowy do wydruku: Nie
