Embodiment 1

[0035] The compressor of Embodiment 1 further includes an air intake pipeline 700 connected to the first suction port 210 , and a second control valve 800 is arranged on the air intake pipeline 700 . The high-pressure pipeline 900, the low-pressure pipeline 1000 and the switching device 1100, the high-pressure pipeline 900 and the low-pressure pipeline 1000 communicate with the third cavity 283 through the switching device 1100, and the switching device 1100 selectively makes the high-pressure pipeline 900 or the low-pressure pipeline 1000 communicates with the third cavity 283 .

[0036] It should be noted that the first compression cylinder 200 in the first embodiment is a variable displacement cylinder.

[0037] Applying the technical solution of this embodiment, since both the first cavity 281 and the second cavity 282 of the compressor communicate with the inner cavity of the housing 100, the tail of the sliding plate 260 and the head of the pin 290 are in a high-pressure...

Abstract

The present invention provides a compressor and a refrigeration system thereof, wherein the compressor includes: a shell, a lower flange structure arranged in the shell from bottom to top, a first compression cylinder and a second compression cylinder, the first The compression cylinder includes: a cylinder body, a roller and a sliding piece. A sliding piece groove is arranged on the inner wall of the cylinder body. The roller is arranged in the cylinder body. The sliding piece is arranged in the sliding piece groove and cooperates with the roller. There is a first reset part between the slide grooves, a lock groove corresponding to the position of the pin groove is arranged on the slide piece, the end of the slide piece far away from the roller forms a first cavity with the bottom of the slide piece groove, and a second A channel to connect the first cavity with the inner cavity of the housing; a second cavity is formed between the first end of the pin and the sliding piece, and a third cavity is formed between the second end of the pin and the bottom of the pin groove , the technical solution of the present invention solves the problem in the prior art that the capacity-changing cylinder of the compressor is easily overloaded after being unloaded and then restarted.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a compressor and a refrigeration system having the same. Background technique [0002] The structure of the three-cylinder two-stage variable capacity compressor in the prior art is as follows: figure 1 and figure 2 As shown, wherein, the variable capacity switching mode of the compressor is: the pressure at the tail of the pin 2' in the variable capacity cylinder 1' is always low pressure, and the pressure in the sealed cavity at the tail of the variable capacity cylinder slide groove 3' (that is, the head of the pin 2' ) can be either high pressure or low pressure. When the tail of the slider groove 3' of the variable capacity cylinder is connected to the low pressure, the pressure on the head of the pin 2' is equal to that of the tail of the pin 2', and the pin 2' moves upward under the elastic force of the spring 4' and blocks the slider 5', The sliding...
