Abstract (en)

[origin: EP4012290A1] A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a refrigerant flow switching device, an air-side heat exchanger, an expansion valve, a water-side heat exchanger, and an accumulator are connected by refrigerant pipes and refrigerant is circulated. G/A is less than or equal to a predetermined threshold χ, where G [L] is a difference in volume between the air-side heat exchanger and the water-side heat exchanger, and A [L] is a volume of the refrigerant circuit.
