To provide a compression type heat pump device capable of reducing drilling costs to utilize underground heat while improving COP by utilizing the underground heat.
This compression type heat pump device is provided with a refrigerant circuit 5 for allowing a refrigerant to successively circulate in a compressor 1 for compressing the refrigerant, a condenser 2 radiating heat from the refrigerant, an expansion valve 3 expanding the refrigerant, and an evaporator 4 allowing the refrigerant to absorb heat, an air heat exchanger 6 in which an object exchanging heat with the refrigerant is the aboveground air, and an underground-heat heat exchanger 7 in which an object exchanging heat with the refrigerant is the underground heat. The refrigerant circuit 5 is constituted to allow the refrigerant after compressed by the compressor 1 to successively pass through the air heat exchanger 6 and the underground-heat heat exchanger 7, and to allow the air heat exchanger 6 and the underground-heat heat exchanger 7 to function as the condenser 2.
