Air intake structure, exhaust structure, compressor, control method and air conditioner

Abstract

The invention provides an air intake structure, an exhaust structure, a compressor, a control method and an air conditioner. The air intake structure comprises a first air cylinder, a second air cylinder, an air suction pipeline and a first on-off device, wherein the first air cylinder is provided with a first air intake channel, and the second air cylinder provided with a second air intake channel; the first air intake channel and the second air intake channel communicate with the air suction pipeline; and the first on-off device controls on and off of the second air intake channel. The exhaust structure comprises a first air cylinder, a second air cylinder and a second on-off device, a second air supplementing channel is formed in the second cylinder in the exhaust structure, one end ofthe second air supplementing channel communicates with a compression cavity of the second cylinder, and the other end of the second air supplementing channel communicates with the exhaust side of thefirst cylinder; and the second on-off device controls the on and off of the second air supplementing channel. According to the single liquid separation air suction design, in the single-cylinder working mode, frozen oil does not flow back to a liquid separator component through the air suction pipeline, so that the air suction superheat degree is reduced, and the refrigerating capacity of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an intake structure, an exhaust structure, a compressor control method and an air conditioner. Background technique [0002] At present, there are two types of double-cylinder variable-capacity compressors. One kind of double-cylinder two-stage variable-capacity compressor has two working modes: single-cylinder single-stage and double-cylinder two-stage. Cylinder single-stage and double-cylinder single-stage two working modes, mainly through the switching mechanism to control whether one of the cylinders works to change the displacement of the compressor. The switching mechanism is mainly composed of a sliding piece with a slot, a pin, a pin hole, and a spring. By controlling the pressure on the head and tail of the pin, the pin moves up and down to block or release the sliding piece, that is, the cylinder does not work when the sliding piece and the roller are se...
