容積可変型ロータリ圧縮機及びその運転方法、並びにそれを備えたエアコンの運転方法
Document Type and Number:
Japanese Patent JP2008508473
Kind Code:
A
Abstract:
In a capacity variable type rotary compressor, its operation method and an operation method of an air conditioner having the same, a plurality of discharge holes are formed, and one of the discharge holes is connected to a bypass hole, which is opened and closed by a sliding valve according to a pressure difference, so as to be selectively connected to an intake hole. Accordingly, a cooling capability lowering rate is increased during capacity varying operation of the compressor, such that the air conditioner can be variously controlled, and unnecessary power consumption of the compressor and the air conditioner having the same can be reduced. Also, by using a pilot valve which is economical and reliable, back pressure of the sliding valve can be speedily and accurately switched. Accordingly, the capacity variable device in accordance with the present invention can be widely used for a compressor or an air conditioner that should perform frequent cooling capability control, and efficiency degradation thereof can be prevented from occurring.
