Threeway reversing valve IMI hydronic
Threeway reversing valve DN 25 with thermal actuator Heat flow Q = 21000 W Temperature adjustment Δt = 20 K (70/50°C) Solution: Mass flow m = Q / (c Δt) = 21000 / (1,163 20) = 903 kg/h Pressure loss from diagram Δp V = 31 mbar DN 15 (Kvs 2,47)
Reversing valve
A reversing valve is a type of valve and is a component in a heat pump, that changes the direction of refrigerant flow By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa This allows a residence or facility to be heated and cooled by a single piece of equipment, by the same means, and with the same hardware
