Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/1998/006983
Kind Code:
A1
Abstract:
An air conditioner which comprises a refrigerant circuit (1), in which a refrigerant flows through a compressor (2), a condenser (3), a heat exchanger (10) for supercooling, a first expansion mechanism (4) and an evaporator (5) in this order. The refrigerant circuit (1) allows the refrigerant discharged from the compressor (2) to be condensed in the condenser (3), and allows the refrigerant condensed to be supercooled by the heat exchanger (10) for supercooling. After pressure reduced in the first expansion mechanism (4), the refrigerant is evaporated in the evaporator (5) to be sucked into the compressor. Use of nonazeotrope refrigerant as the refrigerant can increase improvement effect of a refrigerating capacity due to supercooling as compared with the case where a single refrigerant is used.
