Abstract

PURPOSE: To keep the water at a preset temperature and besides, guarantee the lowest pressure so as to improve the performance of the device, by providing a heat pump device with an electric drive control valve between a compressor and a evaporator, and providing it with a bypass passage within the electric drive control valve. CONSTITUTION: It is so controlled as to be close to the set water temperature Ta, by opening an electric drive control valve 7b in case that the set water temperature Ta of a controller 8 is lower than the temperature Tb of water at exit measured by a detection element 8a, and closing the valve in case that the set water temperature Ta is lower than the water outlet temperature Tb conversely. When the capacity required for a heat pump device is small, the capacity is made small by throttling the aperture of the valve and lowering the evaporation temperature and reducing the flow of the refrigerant circulating in the heat pump. In this case, a bypass passage 7b is constituted in the electric motor driven control vale 7, even if the load capacity decreases, and the flow regulator 7a of the electric motor driven valve 7 closes fully by the signal from the controller 8, the lowest flow flows to the bypass passage 7b, so the lowest pressure is secured.
