Abstract (en)
[origin: US2013213078A1] Obtained is an air-conditioning apparatus capable of having a thin low-pressure gas pipe even when a refrigerant with a low refrigerant density at low pressure is used. An air-conditioning apparatus includes a refrigerant circuit connecting a compressor, a heat source side heat exchanger, expansion devices, and use side heat exchangers with pipes and circulating a refrigerant whose density in a saturated refrigerant gas at 0 degrees C. is 35 to 65% of the density of an R410A refrigerant, and supercooling means (supercooling heat exchanger, expansion device, and bypass) making a liquid temperature sent from the heat source side heat exchanger to the expansion devices be 5 degrees C. or less in a cooling operation.
