Abstract
Disclosed herewith is an air conditioner with a pressure regulation device. The air conditioner controls the number of operated compressors according to load. The air conditioner includes a plurality of bypass conduits for guiding gaseous refrigerant from the outlet sides of compressors to the inlet sides of the compressors. A plurality of bypass valves are arranged on the bypass conduits for selectively opening and shutting the bypass conduits. A control unit controls the opening and closing of the bypass valves so as to control pressure in the inlet sides of one or more started compressors during the starting of the compressors. In addition, a method for controlling the air conditioner is disclosed.
