Abstract (en)

An air-conditioner having multiple compressors (20,22,24,26) includes: an indoor heat-exchanger (2) disposed indoors and heat-exchanging indoor air; an outdoor heat-exchanger (4,6) disposed outdoors and heat-exchanging a refrigerant with external air; four compressors (20,22,24,26) for compressing the refrigerant to change the refrigerant to have a high temperature and high pressure; and three accumulators (30,32,34) disposed at a suction side of the four compressors (20,22,24,26) and separating the refrigerant into a gas and a liquid to supply a gaseous refrigerant to the compressors (20,22,24,26). Oil can be uniformly supplied to each compressor (20,22,24,26), thereby enhancing reliability of compressors (20,22,24,26), and since the three accumulators (30,32,34) are small with low capacities, their installation space can be easily secured.
