Abstract

PURPOSE: To suppress temperature fluctuation of a water circulation circuit by providing an electrically driven control valve for regulating the opening of a valve with a control signal from a controller. CONSTITUTION: When the set water temperature Ta of a controller 8 is higher than the water outlet temperature Tb, an electrically driven control valve 7 is opened otherwise the valve is closed thus controlling the water temperature close to the set level. When the capacity being required for a heat pump is low, valve opening is restricted to lower the evaporation temperature thus lowering the flow rate of refrigerant circulating the heat pump and reducing the capacity thereof. Since a lowest opening (20%) is set for the control valve 7, (radiator side load)<(capacity of heat pump) is satisfied when the capacity drops below the lower limit and the water outlet temperature drops below the set temperature of the controller 8 the heat pump is stopped by the controller 8.
