Embodiment Construction
[0025] The invention discloses a two-stage compressor, which improves the working energy efficiency of the compressor under different working conditions; the invention also provides an air-conditioning system; and the invention also provides an air-supplementing structure of the air-conditioning system.
[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0027] Such as figure 1 and figure 2 as shown, figure 1 Schematic diagram of the explosive structure of the two-stage compressor provided by the present i...

Disclosed is a dual-stage compressor, comprising an upper air cylinder (102) and a lower air cylinder (101), a middle baffle plate (103) being disposed between the two; a sliding plate groove for accommodating a lower air cylinder sliding plate (104) is disposed within the lower air cylinder (101), the bottom of the lower air cylinder (101) also being provided with a lower flange (105); a tail part closed chamber (14) in communication with the sliding plate groove is disposed at the end of the lower air cylinder (101) nearest to an air inlet thereof; an air control passage in communication with the tail part closed chamber (14) and an air intake port of the lower air cylinder (102) is disposed on the upper air cylinder (102) and the middle baffle plate (103); and an air control locking structure for fastening or loosening the lower air cylinder sliding plate (104) is disposed in the tail part closed chamber (14). During the process of air compensation of the upper air cylinder (102), part of the compensated air pressure flows via the air control passage into the tail part closed chamber (14) to control the fastening or loosening of the lower air cylinder sliding plate by the air control locking structure, thereby controlling whether the lower air cylinder (101) is implementing air suction and compression and controlling whether the lower air cylinder (101) is entering an air compensation operation; the switch of the dual-stage compressor between single and dual-stage is thereby adjusted, and the performance of the compressor is improved. An air compensation system of an air conditioning system and an air conditioning system are also disclosed.
Description
technical field [0001] The invention relates to the technical field of air-conditioning equipment, and more specifically relates to an air-conditioning system, an air-supplementing structure for the air-conditioning system, and a two-stage compressor. Background technique [0002] At present, the two-stage rotary compressor mainly includes a first compression cylinder and a second compression cylinder, and the exhaust port of the first compression cylinder is connected to the suction port of the second compression cylinder to compress the gaseous refrigerant twice. [0003] The existing two-stage compressor only has the function of two-stage + air supply, which can broaden the scope of use of the compressor in low-temperature or high-temperature extreme conditions. However, the energy efficiency at the middle point is low, and the energy efficiency improvement at the rated point is not obvious. Suction air flows in from the main separator, and after the primary compression ...
