Claims

[Scope of utility model registration request]

A heat pump system consisting of a heat pump refrigerant circuit consisting of a compressor, a heat exchanger on the user side, a heat exchanger on the heat source side, and a throttling device, in which the throttling of the throttling device can be controlled or the piping constituting the refrigerant circuit A first bypass pipe is provided to bypass the expansion device, and in the case of the heat source side heat exchanger, two heat source side heat exchangers, a first heat source side heat exchanger and a second heat source side heat exchanger, are provided from the user side heat exchanger side. The heat source side heat exchangers are connected in series, and a second throttle device is provided on the piping between the two heat source side heat exchangers, and this second throttle device is controllable, or this second throttle device is A second bypass pipe is provided on the pipe to bypass the two heat source side heat exchangers and transfer the refrigerant sent from the user side heat exchanger from the second heat source side heat exchanger to the first heat source side heat. A third bypass pipe has a switching valve that sends the refrigerant to the exchanger, and a switching valve that bypasses the refrigerant sent from the second heat source side heat exchanger to the first heat source side heat exchanger to the pipe connected to the compressor. A heat pump system with a defrosting function that is equipped with a fourth bypass pipe.
