摘要： It aims, in a heat pump apparatus, to enable to perform switching between high efficiency operation, being efficient, and high capacity operation, having high capacity, according to the state of the load. There are provided a main refrigerant circuit 101 that uses an ejector 4, a first sub-refrigerant circuit 102 that connects a portion between a heat exchanger 2 and an ejector 4 to a portion between a gas-liquid separator 5 and a heat exchanger 3, and a second sub-refrigerant circuit 103 that connects a portion between the heat exchanger 2 and the ejector 4 to an injection pipe 25 of a compressor 1. When the load is about medium, refrigerant is circulated in the main refrigerant circuit 101 to perform an efficient ejector aided operation utilizing the ejector 4. When the load is large, a high capacity injection operation is performed by flowing refrigerant to the second sub-refrigerant circuit 103. When the load is small, a simple bypass operation which prevents degradation of efficiency is performed by flowing refrigerant to the first sub-refrigerant circuit 102.
