WIPO Patent Application WO/2021/014644
Kind Code:
A1
Abstract:
This air conditioning apparatus includes: a refrigerant circuit that has a compressor, a refrigerant flow path switching device, a heat-source-side heat exchanger, a restriction device, a heat transfer medium heat exchanger, and an accumulator connected by refrigerant piping, and that circulates a refrigerant; a heat transfer medium circuit that has a pump, the heat transfer medium heat exchanger, a heat transfer medium flowrate adjusting device, and a load-side heat exchanger connected by heat transfer medium piping, and that circulates a heat transfer medium; at least one bypass pipe which is provided in the refrigerant circuit so that the refrigerant discharged from the compressor bypasses the heat-source-side heat exchanger and/or the heat transfer medium heat exchanger; a bypass opening/closing device provided midway along the pipe line of the bypass pipe; and a control device that controls the bypass opening/closing device so as to execute a start control function by which a significantly superheated low-pressure gas refrigerant is made to flow into the accumulator.
