REFRIGERATION CYCLE APPARATUS

摘要

A refrigeration cycle apparatus includes connected in series a compressor, an oil separator, a condenser, an expansion valve, and an evaporator, and comprising: a distributor communicating to the oil separator and configured to branch a flow of refrigerating machine oil separated within the oil separator; a first oil return flow path to cause the flow of the refrigerating machine oil branched by the distributor to flow into a suction side of the compressor, the first oil return flow path including an expansion valve; and a second oil return flow path to cause the flow of the refrigerating machine oil branched by the distributor to flow into the suction side of the compressor, the second oil return flow path including an oil tank accumulating refrigerating machine oil and a valve provided between the oil tank and the suction side of the compressor, the distributor having a distributor main body in which an inflow opening port communicating to the oil separator, a first oil return opening port communicating to the first oil return flow path, and a second oil return opening port communicating to the second oil return flow path are formed, the first oil return opening port provided at an upper portion of the distributor main body, the second oil return opening port being provided at a lower portion of the distributor main body.
