Air conditioner system

Abstract

The invention provides an air conditioner system. The air conditioner system includes a compressor. The compressor includes a pump body assembly. The pump body assembly includes a first air cylinder and a rotor. A cylinder body of the first air cylinder is provided with a first air suction inlet, a first air exhaust outlet, a first air replenishing inlet and a first air replenishing channel. The first air replenishing channel can optionally communicate with the first air replenishing inlet. The cylinder body is further provided with a first sliding piece and a first sliding piece groove. The first end of the first sliding piece abuts against the periphery of the rotor to divide a compression cavity into an air suction cavity and an air exhaust cavity. When the first air replenishing channel and the first air suction inlet jointly communicate with the air suction cavity, the first air replenishing channel is closed; and/or when the first air replenishing channel and the first air exhaust outlet jointly communicate with the air exhaust cavity, the first air replenishing channel is opened when the air replenishing pressure is equal to or greater than the pressure in the air exhaust cavity, and the first air replenishing channel is closed when the air replenishing pressure is less than the pressure in the air exhaust cavity. According to the air conditioner system, air replenishingand backflow can be avoided, meanwhile, the strength of a sliding piece is ensured, and air replenishing resistance is reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning system. Background technique [0002] The existing two-stage rotor compression mostly adopts the form of two cylinders connected in series to supplement air in the middle. The compression and air supply process is as follows: the refrigerant compressed by the low-pressure stage cylinder is discharged through the exhaust outlet, mixed with the supplementary air, and then enters the high-pressure stage cylinder. further compression. From this process, it can be seen that most refrigerants need to go through two suction and two exhaust processes, and mix with supplementary air in the middle chamber, so there is flow resistance loss and mixing loss. [0003] In order to solve this problem, parallel compression technology came into being. The so-called parallel compression technology is to set up two cylinders with different volumes—the main c...

Problems solved by technology

However, from the point of view of the compression process, the compression process of parallel compression belongs to single-stage compression. When operating in low temperature and ultra-low temperature conditions with a large pressure ratio, the pressure ratio exceeds the range of the general single-stage compression pressure ratio, resulting in the compression process of the main cylinder. Efficiency drops rapidly

[0004] In addition, due to the simple structure and low cost of the single-cylinder air supply technology, it has gradually rece...
