摘要
Disclosed herein is a heat pump and compressor discharge pressure controlling apparatus for the same. The heat pump comprises a compressor, indoor and outdoor heat exchangers for condensing or evaporating refrigerant compressed by the compressor according to cooling or heating operation mode, a four-way valve for guiding the flow of the compressed refrigerant to the indoor heat exchanger or the outdoor heat exchanger according to the operation mode, an expansion valve for selectively decreasing the pressure of liquid refrigerant according to the operation mode, a check valve selectively opened or closed according to the operation mode for guiding the flow of the liquid refrigerant to the expansion valve, an accumulator for preventing the liquid refrigerant from entering into the inlet of the compressor, connection pipes, and a heat exchange part for performing heat exchange between the connection pipe connected to the inlet of the accumulator and the connection pipe connected to the indoor heat exchanger.
