Abstract
Provided is an air-conditioning apparatus capable of performing a cooling and heating mixed operation, including: a heat source unit including a compressor; a plurality of indoor units; a relay unit; a first relay unit-side bypass pipe configured to cause a part of refrigerant, which is discharged from the compressor and flows into the relay unit, to flow between a heat source unit-side heat exchanger and an indoor unit-side heat exchanger; a second relay unit-side flow rate control device provided to the first relay unit-side bypass pipe; and a controller configured to control an opening degree of the second relay unit-side flow rate control device so that, in an operation in which the heat source unit-side heat exchanger functions as an evaporator, a discharge temperature of a discharge refrigerant discharged from the compressor is equal to or lower than a heat-resistant temperature of the compressor.
