Abstract:
Disclosed are a heat-source-side unit and a refrigeration air conditioner, both of which enable the effective utilization of tanks or the like and also enable highly efficient recovery or the like.
Specifically disclosed is a heat-source-side unit (100) which comprises a compressor (101) and a heat-source-side heat exchanger (104), and also comprises a coolant circuit which is formed by the pipe connection between a load-side throttle device (202) and a load-side heat exchanger (201). In the heat-source-side unit (100), the coolant circuit is provided with an oil tank (110) for feeding a refrigerating machine oil that is lost by the washing of the coolant circuit into the compressor (101) to refill the refrigerating machine oil.
