Abstract (en)

[origin: EP1655553A2] An air conditioner and a method for controlling the same, in which the quantity of a refrigerant supplied to indoor heat exchangers (evaporators) is controlled according to the opening degrees of indoor electric expansion valves and super heating temperatures of the indoor heat exchangers (evaporators), thereby increasing cooling efficiency of the air conditioner. The method includes operating a compressor to compress the refrigerant, supplying the compressed refrigerant, condensed by an outdoor heat exchanger, to indoor units through an outdoor expansion valve, and controlling an opening degree of the outdoor expansion valve according to opening degrees of indoor expansion valves of the indoor units, performing cooling operation, and super heating temperatures of the indoor units to control the quantity of the refrigerant supplied to the indoor units.
