Claims

[Scope of utility model registration request]

The outdoor heat exchanger, throttling device, and indoor heat exchanger are sequentially connected to the compressor via a four-way valve to form a main path, and the compressor discharge side and the outdoor heat exchanger are connected to each other by piping during heating operation. In a heat pump device in which a side passage is provided between the suction side and a solenoid valve that opens during defrosting operation, the side passage connected to the discharge side of the compressor is branched, and one side is used for heating operation of the outdoor heat exchanger. At the time, the suction side is connected to the middle part of the outdoor heat exchanger, and the other is connected to the middle part of the outdoor heat exchanger. 1. A heat pump device comprising electromagnetic valves each of which is controlled to open and close based on the temperature of the piping.
