Description

Technical Field

[0001] The present invention belongs to the technical field of refrigeration equipment, and particularly relates to a compressor and an air conditioner. Background Art

[0002] A conventional rolling rotor compressor mainly consists of two major parts: a compressor body and a liquid receiver. Among them, the liquid receiver mainly consists of an inlet pipe, a filter screen and a filter screen support, a liquid receiver housing, a straight pipe and an outlet elbow pipe. The compressor body mainly consists of a pump body assembly, a motor assembly, an upper cover, a housing and a lower cover. The housing and the upper and lower covers cooperate to form a closed structure, and the pump body assembly and the motor assembly are assembled inside the housing. The liquid receiver is arranged on one side of the compressor body and is fixed on a liquid receiver support on the housing of the compressor body through a liquid receiver pressing plate. Its inlet pipe is connected to the system pipeline, and the outlet elbow pipe is connected to the pump suction hole of the compressor body. The upper cover part is provided with U / V / W three-phase terminal posts, which are connected to an independent control driving device. Under the control and drive of the driving device, the motor drives the compressor pump body to rotate to suck and compress to generate high-temperature and high-pressure refrigerating gas, which enters the system pipeline through the compressor outlet pipe. After being condensed and evaporated by the system pipeline and transformed into low-temperature and low-pressure gas, it then enters the liquid receiver through the liquid receiver inlet pipe. After being filtered by the liquid receiver filter screen, it flows through the liquid receiver straight pipe and the outlet elbow pipe and enters the compressor pump body, realizing the periodic cyclic working process of the compressor and the system pipeline.

[0003] The above-mentioned conventional rotary compressor needs to be equipped with a separate control driving device. The liquid receiver, the compressor body, and the compressor and the control driving device are all independent and separated components, occupying a large space and having a complex assembly, which is not conducive to the development of the air-conditioning system towards small and compact. On the other hand, for low-temperature, especially ultra-low-temperature harsh working conditions, the liquid content of the refrigerant gas flowing through the liquid receiver is too large, causing the compressor pump body to suck liquid, resulting in problems such as a decrease in compressor capacity and reliability issues such as liquid pressing. Summary of the Invention
