Refrigeration/air conditioning equipment includes a first internal heat exchanger for exchanging heat between a refrigerant to be sucked in a compressor and a high-pressure liquid refrigerant, an injection circuit for evaporating a bypassed high-pressure liquid at intermediate pressure and injecting the vaporized refrigerant into the compressor, a second internal heat exchanger for exchanging heat between the high-pressure liquid refrigerant and the refrigerant to be injected, and a heat source for heating the refrigerant to be injected.
1. Refrigeration/air conditioning equipment comprising: a compressor;a four-way valve;an indoor heat exchanger;a first decompressor; andan outdoor heat exchanger,wherein these components are coupled circularly, and heat is supplied from the indoor heat exchanger,the refrigeration/air conditioning equipment further comprising:an intermediate-pressure receiver disposed between the indoor heat exchanger and the first decompressor;a first internal heat exchanger that exchanges heat between a refrigerant in the intermediate-pressure receiver and a refrigerant...
