[0002] The liquid accumulator has two functions in the air conditioning system, one is to store liquid refrigerant for the evaporator, and the other is to store all the refrigerant in the system when the system is maintained. The high-pressure and high-temperature liquid refrigerant from the condenser is stored in the liquid accumulator, and then supplied to the evaporator through the expansion valve to play a refrigeration function. During the refrigerant circulation process, the flow direction of the refrigerant in the condenser and the evaporator is opposite in the heating state and the refrigeration state by means of the four-way valve. The liquid accumulators in the prior art are mostly of a whole structure, and are inconvenient to install and maintain. In addition, the inlet pipe and the suction pipe usually have a certain height difference, and there is a pressure difference when the refrigerant flows forward and reversely, which leads to an unstable refrigeration system. Moreover, the filtering effect of the filter assembly in the liquid accumulator cannot be guaranteed to be consistent when the refrigerant flows forward and reversely. Therefore, it is necessary to improve the existing liquid accumulator. SUMMARY

[0003] Therefore, the application aims to overcome the defects in the prior art and provides an air conditioner system liquid accumulator body.
