Claim 0:
1. A heat pump device in which a compressor, a gas cooler, a refrigerant heat exchanger, a refrigerant expansion valve, and an evaporator are connected to configure a refrigerant circulation circuit, the heat pump device comprising:
a buffer tank, one end of which is connected to a high-pressure side of the refrigerant expansion valve and arranged to store a refrigerant; and
a first refrigerant pipe, one end of which is connected to the high-pressure side of the compressor and the other end of which is connected to a downstream side of the evaporator and arranged to exchange heat with the buffer tank;
wherein the first refrigerant pipe comprises:
a first control valve arranged between the high-pressure side of the compressor and the buffer tank to control the opening and closing of the first refrigerant pipe; and
a first flow rate regulator arranged between the buffer tank and a downstream side of the evaporator to control the flow rate of the refrigerant.
