Abstract:
A refrigerating apparatus comprising: a heat-source-side unit (A); use-side units (B, C); and at least one of heat exchangers (12, 14) contained in each of the use-side units (B, C), heat generated in the heat-source-side unit (A) being supplied to the use-side units (B, C), at least one (12) of the heat exchangers forming a heat-release-side heat exchanger (12) for performing heat releasing operation, the other (14) of the heat exchangers forming a heat-absorption-side heat exchanger (14) for performing heat absorbing operation,the heat-source-side unit (A) including a heating element (3A), a cooling element (5A), a heat absorbing element (3B) for receiving warm heat from the heating element (3A), and a heat releasing element (SB) for receiving cold heat from the cooling element (5A),transfer means (11), the heat absorbing element (3B), the heat releasing element (5B), and the heat exchangers (12, 14) being connected to each other by a liquid pipe (LL) and gas pipes (GH, GL) to constitute a use-side refrigerant circuit (10) through which a refrigerant circulates,wherein, in the use-side refrigerant circuit (10), the liquid refrigerant is evaporated in the heat absorbing element (3B) with the warm heat from the heating element (3A), the gas refrigerant flows to the use-side units (B, C) via the gas pipe (GH) and releases heat in the heat-release-side heat exchanger (12) to be condensed, the liquid refrigerant absorbs heat in the heat-absorption-side heat exchanger (14) to be evaporated, the gas refrigerant flows to the heat-source-side unit (A) via the gas pipe (GL) to be condensed in the heat releasing element (5B) with the cold heat from the cooling element (5A), and then the liquid refrigerant flows into the heat absorbing element (3B).
