Abstract

PURPOSE: To bring the outdoor unit of a multiple-room type air conditioner into efficient operation in accordance with its load by mounting multipe compressors different in capacity.
CONSTITUTION: On a multiple-room type air conditioner where an outdoor unit 4 is connected with multiple indoor units through pipings 8, a large capacity compressor 1a and a small capacity compressor 1b are arranged in parallel in the outdoor unit and the compressors 1a, 1b are selected and driven separately or together in accordance with the room temperature or the number of the indoor units applied. Therefore, when two indoor units must be used on a normal load, both compressors 1a, 1b will be driven and electromagnetic valves 3 be opened. When load decreases at night, only the large capacity compressor 1a is driven even though both units 7 are working. When one indoor unit is running, either of the compressors 1a, 1b can be switched and used in response to the room temperature.
