Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138052
Kind Code:
A1
Abstract:
This refrigeration cycle device is equipped with a refrigeration circuit through which a refrigerant circulates and which is configured by connecting in a circular arrangement a compressor, a heat-source-side heat exchanger, a decompression device, and a usage-side heat exchanger. The refrigerant is R32. The usage-side heat exchanger is a plate-type heat exchanger wherein a refrigerant and a liquid exchange heat. The plate-type heat exchanger includes a first flow path in which R32 flows and a second flow path in which liquid flows. The cross-sectional area of the first flow path has a ratio of 0.5 or greater with respect to when R410A is used as the refrigerant. Thus, it is possible to provide a refrigeration cycle device that can achieve environmental sustainability.
