Title:
COMPRESSOR AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/109609
Kind Code:
A1
Abstract:
A compressor and an air conditioner are provided herein. The compressor comprises a main shaft (1), a first cylinder (2), and a second cylinder (3). The main shaft (1) sequentially passes through the first cylinder (2) and the second cylinder (3) and can rotate therein, so as to compress refrigerants entering the first cylinder (2) and the second cylinder (3). The second cylinder (3) has an inner cavity (31) capable of receiving the main shaft (1), a changeable capacity control cavity (32) connecting to the inner cavity (31) is provided on the side wall of the inner cavity (31), and a sliding vane (33) is provided inside the changeable capacity control cavity (32). The changeable capacity control cavity (32) can be selectively connected to an air inlet and an air outlet of the compressor, so as to change the pressure in the changeable capacity control cavity (32), and the pressure in the changeable capacity control cavity (32) drives the sliding vane (33) to move to abut or separate from the main shaft (1). The changeable capacity compressor can reduce minimum output thereof, providing precise temperature control, reducing power consumption, and realizing energy conservation.
