HEAT SOURCE SIDE UNIT AND AIR-CONDITIONING APPARATUS
First Claim
1. A heat source side unit connected to a load side unit configured to supply a capacity to a load by a pipe and constituting a refrigerant circuit, the heat source side unit comprising:
- a compressor configured to compress refrigerant and discharge the refrigerant;
a heat source side heat exchanger configured to serve as an evaporator or a radiator;
a channel switching device configured to switch a flow of refrigerant based on a function of the heat source side heat exchanger;
a gas-liquid separator configured to separate inflow refrigerant into liquid refrigerant and gas refrigerant, the gas-liquid separator being configured that a liquid refrigerant outlet from which the liquid refrigerant flows out is connected to a pipe at a refrigerant inflow side when the heat source side heat exchanger serves as the evaporator; and
a bypass pipe connecting a gas refrigerant outlet of the gas-liquid separator from which the gas refrigerant flows out to a pipe at a refrigerant outflow side when the heat source side heat exchanger serves as the evaporator; and
when the heat source side heat exchanger serves as the radiator, the gas-liquid separator and the bypass pipe being connected in parallel to a channel passing through the channel switching device to cause part of the refrigerant flowed from the load side unit to be branched off and bypass the channel switching device.

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.
