Abstract

The invention provides a compressor, comprising an upper cylinder, a lower cylinder and a lower flange, the upper cylinder, the lower cylinder and the lower flange are arranged sequentially from top to bottom, a middle partition is arranged between the upper cylinder and the lower cylinder, and the lower flange An intermediate chamber is provided, which communicates with the lower cylinder, and the gas discharged from the lower cylinder enters the intermediate chamber; the lower flange is also provided with a first outlet and a second outlet for communicating with the intermediate chamber, and the upper cylinder is provided with an upper cylinder suction port , the exhaust of the upper cylinder is discharged from the exhaust port of the compressor, the lower cylinder is provided with a suction port of the lower cylinder, and the exhaust of the lower cylinder is discharged from the first outlet and / or the second outlet. It also relates to an air conditioner. The compressor and the air conditioner of the present invention cooperate with the system to realize the switching between the two-cylinder operation and the two-stage operation of the compressor, which expands the scope of use of the compressor, enables the compressor to have a larger cooling capacity output under high temperature conditions, and The working condition has a lower thermal attenuation.

Description

technical field

[0001] The invention relates to the refrigeration field, in particular to a compressor and an air conditioner. Background technique

[0002] The current compressors can only operate with two cylinders, or can only operate with two stages. Usually, the two cylinders operate with a large cooling capacity output under high temperature conditions, but the heat attenuation is very serious under low temperature conditions. Restricted, dual-stage operation has low heat decay at low temperatures, but lower cooling output at high temperatures relative to dual-cylinder operation. Contents of the invention

[0003] In view of the status quo of the prior art, the object of the present invention is to provide a compressor and an air conditioner. By setting the first and second outlets on the lower flange, the cooperation system realizes the two working modes of the compressor in two stages and two cylinders. to switch between. To achieve the above object, the technica...
