PURPOSE:To improve the working efficiency of the heat pump so that the energy consumption can be saved by a control of the operation of a compressor with a pressure of a coolant at an inlet of the compressor. CONSTITUTION:There is provided a coolant pressure detector A at the inlet of the compressor 2 for controlling the operation of the compressor 2. Under this control of the compressor operation, the discharge pressure of the compressor 2 is kept stable. Thus, the working efficiency of the heat pump 1 can be much improved and the energy consumption can be much saved. |
