Title:
COMPRESSOR AND REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/082958
Kind Code:
A1
Abstract:
A compressor (100) and a refrigeration apparatus. The compressor (100) comprises a housing (110), a first air outflow port (112) and a second air outflow port (114) provided on the housing (110), a first cylinder (140) comprising a first working chamber, a second cylinder (150) comprising a second working chamber, the second working chamber being in communication with the second air outflow port (114) via a cavity of the housing (110), a first partition (160) arranged between the first bearing (120) and the first cylinder (140), and a first air vent (180) provided on the first partition (160) and in communication with the first working chamber, the first air vent (180) being in communication with the first air outflow port (112) via an air discharging channel (190), the air discharging channel (190) and the cavity of the housing (110) being not in communication with each other, and the air discharging pressure of the first working chamber being greater than the air discharging pressure of the second working chamber. With the first partition (160) additionally provided between the first bearing (120) and the first cylinder (140), and with the first air vent (180) provided in communication with the first working chamber on the first partition (160) for discharging air, the hermeticity of the first working chamber while discharging air is effectively increased, and the actual displacement of the first working chamber is brought closer to the displacement of a theoretical design, thus increasing the energy efficiency of the compressor.
