A heat source side unit (100) connected via a pipe to a load side unit (300) to constitute a refrigerant circuit is provided with: a compressor (101) for compressing and discharging a refrigerant; a heat source side heat-exchanger (103) functioning as an evaporator or radiator; a gas-liquid separator (116) for separating the inflow refrigerant into a liquid refrigerant and a gas refrigerant, wherein a liquid refrigerant outflow port for discharging the liquid refrigerant is connected to a connection pipe (404) on the refrigerant inflow side when the heat source side heat-exchanger (103) functions as the evaporator; a sixth connection pipe (125) connecting a gas refrigerant outflow port for discharging the gas refrigerant from the gas-liquid separator (116) to a pipe on the refrigerant outflow side when the heat source side heat-exchanger (103) functions as the evaporator; and a regulator (117) for regulating the refrigerant passing through the sixth connection pipe (125). |
