Refrigerating Apparatus and Air Conditioner |
| abstract |
An air conditioner has a refrigerant circuit and a first oil returning circuit. The refrigerant circuit has a plurality of utilization refrigerant circuits each having a utilization heat exchanger and a utilization expansion valve connected to a heat source refrigerant circuit that includes a compression mechanism, a heat source expansion valve and a heat source heat exchanger configured so that a refrigerant flows in from below and flows out from above when the heat source heat exchanger functions as an evaporator. The heat source refrigerant circuit uses a combination of a refrigerating machine oil and a refrigerant that does not separate into two layers in a temperature range of 30° C. or below. The first oil returning circuit is connected to a lower portion of the heat source heat exchanger and returns the refrigerating machine oil accumulated inside the heat source heat exchanger to the compression mechanism together with the refrigerant. |
