PURPOSE:To provide a heat pump having a plurality of heat sources including a liquid refrigerant transferring and pressurizing means in which a motor for a pump is not required and its small-sized structure can be realized. CONSTITUTION:A liquid refrigerant pressurizing and transferring means comprising a liquid refrigerant transferring unit 9 and a liquid refrigerant storing container biasing means 10 extracts liquid refrigerant from a liquid refrigerant pipe in a main circuit 100 including a compression type heat pump cycle device, stores it, pressurizes it, feeds it to a refrigerant heater 7. The refrigerant heater 7 evaporates the liquid refrigerant under indirect heating got from a second heat source 16 and sends it to a radiator of the main circuit 100. The liquid refrigerant transferring unit 9 is comprised of a closed casing 91 and a refrigerant storing container 92. The liquid refrigerant storing container biasing means 10 comprising a four-way changing-over valve utilizes a pressure difference of gas refrigerant in the main circuit 100, reciprocates and slides the refrigerant storing container 92, thereby performs a flowing of liquid refrigerant and a discharging of liquid refrigerant alternatively between the first pressure container chambers 107 and 108 in the refrigerant storing container 92. |
