Patent ID: 10539343

Abstract:
A heat source side unit connected to load side units by pipes and constituting a refrigerant circuit, includes a compressor that compresses refrigerant and discharges the refrigerant, a heat source side heat exchanger that serves as an evaporator or a radiator, a gas-liquid separator 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 at a refrigerant inflow side in a case where the heat source side heat exchanger serves as the evaporator, a sixth connecting pipe that connects a gas refrigerant outlet of the gas-liquid separator 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 serves as the evaporator, and an expansion device that controls passage of refrigerant in the sixth connecting pipe.
