Estimating the term…
A heat-recovery-type refrigerating apparatus includes a compressor, a heat-source-side heat exchanger, and a plurality of usage-side heat exchangers, and refrigerant is sent from the usage-side heat exchanger functioning as a refrigerant radiator to the usage-side heat exchanger functioning as a refrigerant evaporator, whereby heat can be recovered between the usage-side heat exchangers. Here, a portion of the heat-source-side heat exchanger is configured as a precooling heat exchanger for always circulating high-pressure vapor refrigerant discharged from the compressor, and a refrigerant cooler for cooling an electrical equipment item is connected to a downstream side of the precooling heat exchanger.
A heat-recovery-type refrigerating apparatus including a compressor, a heat-source-side heat exchanger, and a plurality of usage-side heat exchangers which can each individually be switched between functioning as refrigerant evaporators or refrigerant radiators, refrigerant being sent from said usage-side heat exchanger functioning as a refrigerant radiator to said usage-side heat exchanger functioning as a refrigerant evaporator, whereby heat can be recovered between said usage-side heat exchangers;
