An air conditioner and a method of controlling the air conditioner includes a variable capacity compressor being operated at a maximum capacity in a case of starting an operation of the compressor after an extended stoppage for a lengthy period of time longer than a preset reference time, thus increasing a flow rate of a circulated refrigerant during an initial stage of the operation and increasing a quantity of heat generated from the motor of the compressor to vaporize and forcibly discharge a remaining liquid refrigerant from the compressor during the initial stage. Therefore, the variable capacity compressor of the air conditioner does not require heaters conventionally used for heating the refrigerant during such a stoppage, and so easy designing and production of the compressor is achieved, in addition to a reduction in a production cost of the air conditioner. This air conditioner also accomplishes a reduction in a maintenance cost thereof.

Air conditioner and control method thereof

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.

Air conditioner with a pressure regulation device and method for controlling the same

A component assembling machine driving device and a method thereof are disclosed, in which a cam is used as the principal device for realizing speedy operations, in which a position controller and a sequence controller are capable of monitoring the state of the cam by means of a simple combination of sensors, and in which different operations are carried out simultaneously, thereby achieving speedy operations, but preventing interferences between different operations.
