Abstract

A compressor includes a housing (101) and a pair of rotors (110). The pair of rotors (110) is disposed in the housing (101). A compression accommodating cavity (105) is formed between the pair of rotors (110) and an inner wall of the housing (101). The housing (101) is provided with a housing fitting surface (135) facing exhaust ends (122) of the pair of rotors (110). At least one auxiliary exhaust port (312, 313) is provided in the housing fitting surface (135). The at least one auxiliary exhaust port (312, 313) is configured to be capable of being opened and closed. When the at least one auxiliary exhaust port (312, 313) is opened, the compression accommodating cavity (105) can be in communication with a compressor exhaust port (142) by means of the at least one auxiliary exhaust port (312, 313). The shape of at least part of an edge of the at least one auxiliary exhaust port (312, 313) conforms to the shape of profiles of teeth of the pair of rotors (110). The at least one auxiliary exhaust port (312, 313) is configured to be opened or closed according to an internal volume ratio of the compressor and a system pressure ratio, such that the internal volume ratio of the compressor and the system pressure ratio match each other.
