<p>A refrigerating device, wherein, in a heat recovery operation, the refrigerant discharged from a compressor (2B) is condensed in an air conditioner heat exchanger (41), passed through an expansion valve (46), evaporated in a refrigerator heat exchanger (45) and a freezer heat exchanger (51), and returned to the compressor (2B); in an excessive heating capacity operation, a part of the refrigerant discharged from the compressor (2B) is condensed in the air conditioner heat exchanger (41), the remaining refrigerant is condensed in an outdoor heat exchanger (4), all condensed liquid refrigerant is passed through the expansion valve (46), evaporated in the refrigerator heat exchanger (45) and the freezer heat exchanger (51), and returned to the compressor (2B); in the heating in adequate capacity operation, the refrigerant discharged from the compressor (2B) is condensed in the air conditioner heat exchanger (41), a part of the condensed liquid refrigerant is passed through the expansion valve (46) and evaporated in the refrigerator heat exchanger (45) and the freezer heat exchanger (51), the remaining liquid refrigerant is passed through an expansion valve (26) and evaporated in the outdoor heat exchanger (4), and the evaporated gas refrigerant is returned to the compressor (2B).</p> |
