Abstract (en)

[origin: EP3415841A1] A refrigeration cycle device of the present invention includes a refrigerant circuit configured by annularly connecting a compressor, a heat source-side heat exchanger, a pressure reducing device, and a using-side heat exchanger, and through which a refrigerant circulates. The refrigerant is R32. The using-side heat exchanger is a plate-type heat exchanger in which the refrigerant and a liquid exchange heat. The plate-type heat exchanger includes a first channel through which the R32 flows, and a second channel through which the liquid flows. A ratio of a sectional area of the first channel relative to a sectional area of the first channel when R410A is used as the refrigerant is not lower than 0.5. Thus, a highly environment-friendly refrigeration cycle device can be provided.
