HEAT PUMP |
摘要 |
To provide a heat pump capable of operating in a high COP state even if the influx temperature of a medium to be heated flowing into the radiators has increased. An heat pump in which a compressor 1, a first radiator 2, a second radiator 4, an expansion valve 6, and an evaporator 7 are sequentially connected by refrigerant piping to form a first refrigeration cycle, in which a first refrigerant circulates in the first refrigeration cycle, and in which the first radiator 2 and the second radiator 4 are serially connected, a first heat exchange unit that heats the first refrigerant is provided in a refrigerant piping at a refrigerant inlet side of the second radiator 4, and a second heat exchange unit that cools the first refrigerant is provided in a refrigerant piping at a refrigerant outlet side of the second radiator 4. |
