ROOM AIR CONDITIONER HAVING COMPRESSOR WITH VARIABLE CAPACITYAND CONTROL THEREFOR

摘要

A room air conditioner with a compressor having variable capacity is provided by the invention, with the variable capacity automatically adjusted to balance with the refrigeration load of the space being cooled. A movable valve progressively opens a portion of the compressor cylinder to the suction side of the system so that a progressively reduced volume of active cylinder is available for compression. The volume available for compression is automatically proportioned by a control arrangement which is actuated by the temperature of the space being cooled.
