ABSTRACT:
A capacity variable device for a rotary compressor and an operation method of an air conditioner having the same are provided. The capacity variable device includes a valve hole in which a sliding valve slidingly inserted is formed at a cylinder, and a bypass hole formed to cross the valve hole and communicating with an intake hole of the cylinder such that resistance of a refrigerant being bypassed is reduced and the operation is performed with its cooling capability lowered. Various operation modes of the air conditioner employing the same are performed and a power consumption is reduced, thus, the efficiency of the compressor is improved. In addition, a structure of the capacity variable device is simplified, thereby lowering a manufacturing cost, simplifying assembly and thusly improving productivity.
