20140311177 | REFRIGERATION APPARATUS - A refrigeration apparatus includes a multistage compression mechanism, switching mechanisms, intercoolers, oil separators, and a control unit. The multistage compression mechanism has one high-stage-side compression mechanism and a plurality of low-stage-side compression mechanisms connected in series. The switching mechanisms are connected to blow-out pipes of the low-stage-side compression mechanisms. The switching mechanisms switch between cooling and heating operation cycles. The intercoolers cool refrigerant blown out from the low-stage-side compression mechanisms during the cooling cycle. The oil separators are disposed between the switching mechanisms and the intercoolers. The oil separators separate lubricating oil from refrigerant blown out from the low-stage-side compression mechanisms during the cooling cycle. The control unit controls the multi-stage compression mechanism and the switching mechanisms. Refrigerant from the low-stage-side compression mechanisms passes through the oil separators and intercoolers during the cooling cycle, not during the heating cycle. | 10-23-2014 |
