Abstract

The invention provides an air intake structure, an exhaust structure, a compressor, a control method and an air conditioner. The air intake structure includes: a first air cylinder is provided with a first air intake channel, and a second air cylinder is provided with a second air intake channel; An air intake channel and a second air intake channel communicate with the suction pipeline; the first on-off device controls the on-off of the second air intake channel. In the exhaust structure, a second air supply channel is provided on the second cylinder, one end of the second air supply channel communicates with the compression chamber of the second cylinder, and the other end of the second air supply channel communicates with the exhaust side of the first cylinder; Two on-off devices, the second on-off device controls the on-off of the second air supply channel. Single liquid suction design, in the single cylinder working mode, the refrigerated oil will not flow back to the liquid separator parts through the suction pipeline, thereby reducing the suction superheat and increasing the cooling capacity of the compressor.

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...
