WIPO Patent Application WO/2020/155727
Kind Code:
A1
Abstract:
Provided is a scroll compressor, comprising: a scroll assembly comprising a movable scroll (30, 130, 230), and a fixed scroll (20, 120, 220), with a longitudinal channel (126, H1, H2) which is in communication with at least one of multiple compression cavities (C, C1, C2) being provided at an end plate of the fixed scroll; an injection channel (150, 250a, 250b), which can be in communication with the at least one compression cavity through the longitudinal channel and allows the injected fluid to be injected into the at least one compression cavity so as to increase the capacity of the compressor; a bypass channel (160, G), which can be in communication with the at least one compression cavity through the longitudinal channel and allows the compressed fluid to leak out of the at least one compression cavity so as to reduce the capacity of the compressor; and a switching assembly at least comprising a movable part (170, 210), which is adapted to be controlled so that same can move between a first position and a second position so as to selectively allow the bypass channel to be in communication with or separated from the at least one compression cavity. The scroll compressor has a simple structure, low costs, and high reliability. A climate control system comprising the scroll compressor is further provided.
