Air conditioner refrigeration system and liquid reservoir thereof

Abstract

The invention discloses a liquid reservoir which comprises a lower reservoir body and a filter barrel, wherein a refrigerant inlet and a refrigerant outlet are formed at the lower end of the lower reservoir body; the filter barrel is matched with the inner wall of the lower reservoir body to form a liquid flow cavity; the filter barrel comprises a barrel wall made of a filter material, an upper liquid flow barrel and a lower liquid flow barrel; the upper liquid flow barrel and the lower liquid flow barrel are arranged at two ends of the barrel wall and communicated with each other; the lower liquid flow barrel and the liquid flow cavity are communicated with the refrigerant inlet and the refrigerant outlet respectively; and a refrigerant is at least filtered once in a process of flowing from the refrigerant inlet to the refrigerant outlet. The invention also discloses an air conditioner refrigeration system with the liquid reservoir. The refrigerant flows into the liquid flow cavity from the refrigerant inlet, further flows through the filter barrel and flows out from the refrigerant outlet, thus impurities in the refrigerant are stopped in the liquid reservoir, and an aim of filtering the refrigerant is achieved. According to the liquid reservoir, the filter barrel, instead of a non-woven cloth, is utilized as a filter part for the refrigerant, so that the own filter precision of the liquid reservoir is guaranteed, and simultaneously the flow resistance is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration systems, in particular to a liquid receiver with low flow resistance. The present invention also relates to an air-conditioning and refrigeration system with the above-mentioned liquid receiver. Background technique [0002] The liquid receiver is a relatively important accessory in the refrigeration system. Its function is to filter impurities in the refrigerant, absorb moisture in the refrigerant and store a certain amount of refrigerant. Therefore, it is widely used in refrigeration systems such as automobile air conditioners. At present, there are many types of liquid reservoirs in automobile air conditioners, among which the application range of upper and lower body liquid reservoirs is relatively wide. [0003] see figure 1 , figure 1 It is a schematic diagram of the structure of a typical liquid reservoir. [0004] Such as figure 1 As shown, the liquid reservoir has a slender sha...

AI Technical Summary

Problems solved by technology

The inventors found that under the same cross-sectional area, the higher the density of the non-woven filter 25, the greater the flow resistance, which will increase the load on the refrigeration system.

On the other hand, due to the large flow resistance of the non-woven filter 25, impurities in the refrigerant are easy to accumulate on the surface of the non-woven filter 25, resulting in weakened flow capacity of the non-woven filter 25 and a further increase in its flow resistance. Large, thus causing a vicious circle, seriously affecting the performance of the refrigeration system
