SCROLL COMPRESSOR AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/219660
Kind Code:
A1
Abstract:
A scroll compressor and an air conditioner. The scroll compressor (100) comprises an orbiting scroll member (30) and a non-orbiting scroll member (20) which are engaged with each other to form a compression cavity (1a). The non-orbiting scroll member (20) comprises a non-orbiting member body (21). The non-orbiting member body (21) is provided with a first channel (213) running through the non-orbiting member body (21) in the axial direction, a second channel (214) extending on a side face of the non-orbiting member body in the radial direction, and a third channel with one end thereof being in communication with the first channel (213) and the other end thereof being in communication with the second channel (214). A movable valve plate (40) is provided in the third channel. The movable valve plate (40) controls the first channel (213) and the second channel (214) to be in communication with each other or disconnected from each other according to the air pressure difference between the first channel (213) and the second channel (214). Thus, when it does not need to convey refrigerants to the compressor, the clearance volume for communication of the first channel (213) and the second channel (214) with the compression cavity is reduced, and the performance of the scroll compressor is improved.
