A refrigeration cycle apparatus comprising:
- a heat source side unit;
- a relay unit;
- and
- a plurality of load side units,
- wherein the heat source side unit and the relay unit are connected by using a low-pressure pipe and a high-pressure pipe, and
- the relay unit and each of the plurality of load side units are connected by using a liquid branch pipe and a gas branch pipe,
- wherein the heat source side unit includes
- a compressor configured to compress refrigerant,
- at least one flow switching valve configured to change a passage of refrigerant based on an operation mode, and
- at least one heat source side heat exchanger, and
- the relay unit includes
- six-way valves or pairs of four-way valves, each of the six-way valves or each of the pairs of four-way valves being connected to each of the plurality of load side units, and
- a gas-liquid separator whose inlet is connected to the high-pressure pipe, and
- wherein each of the six-way valves or each of the pairs of four-way valves is connected to a gas outlet of the gas-liquid separator, a liquid outlet of the gas-liquid separator, the gas branch pipe and the liquid branch pipe connected to each of the plurality of load side units, and the low-pressure pipe.
