A heat source side unit 100 connected to load side units 300 by pipes and constituting a refrigerant circuit, includes a compressor 101 that compresses refrigerant and discharges the refrigerant, a heat source side heat exchanger 103 that serves as an evaporator or a radiator, a gas-liquid separator 116 that separates inflow refrigerant into liquid refrigerant and gas refrigerant, a liquid refrigerant outlet from which the liquid refrigerant flows out being connected to a connecting pipe 404 at a refrigerant inflow side in a case where the heat source side heat exchanger 103 serves as the evaporator, a sixth connecting pipe 125 that connects a gas refrigerant outlet of the gas-liquid separator 116 from which the gas refrigerant flows out to a pipe at a refrigerant outflow side in a case where the heat source side heat exchanger 103 serves as the evaporator, and an expansion device 117 that controls passage of refrigerant in the sixth connecting pipe 125. |
