Abstract

The invention discloses a liquid accumulator which comprises a shell, an air inlet pipe, an air outlet pipe and at least one separating device. The air inlet pipe and the air outlet pipe are arranged on the shell in a spaced mode, the air inlet pipe and the air outlet pipe are both communicated with the interior of the shell, and the separating device is arranged in the shell and is located between the air inlet pipe and the air outlet pipe so as to conduct air and liquid separation on a air-liquid refrigerant mixture entering the shell from the air inlet pipe. According to the liquid accumulator, the separating device is arranged in the liquid accumulator, the separating device can conduct air and liquid separation on the air-liquid refrigerant mixture entering the liquid accumulator, and therefore the air-liquid refrigerant mixture in the liquid accumulator at least passes through two-time air-liquid separation, the number of liquid refrigerants absorbed by a compressor is reduced, and the reliability of the compressor is improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a liquid accumulator. Background technique [0002] The liquid accumulator is an important part of the compressor, especially the rolling rotor compressor. Its main function has two aspects: one is to prevent impurities from entering the compressor and damage the pump body of the compressor; the other is to prevent the compressor from being damaged in an unstable state. During operation, liquid refrigerant flows into the compressor and causes liquid shock, which damages the pump body of the compressor. In addition, the accumulator must also ensure that the lubricating oil flowing with the refrigerant returns to the compressor to ensure that the compressor is not in a state of oil shortage. [0003] It is pointed out in the related art that when the accumulator is used as a medium-pressure air supplement tank, it is used in a secondary or quasi-secondary system with supplem...

Problems solved by technology

[0003] It is pointed out in the related art that when the accumulator is used as a medium-pressure air supplement tank, it is used in a secondary or quasi-secondary system with supplementary air, especially in a system with complete cooling in the middle, or when the accumulator is in a low superheated In the system, there is a high possibility of liquid refrigerant entering the accumulator, especially when the working conditions change, it may cause a large amount of liquid refrigerant to enter the liquid accumulator, which will lead to two serious situations: First, the pump body of the compressor is likely to Too much liquid refrigerant will be sucked in, causing abnormal high pressure and insufficient lubrication inside the compressor pump body, resulting in abnormal noise and wear of the pump body; second, because liquid refrigerant is denser than lubricating oil, liquid refrigerant deposits in the liquid reservoir The bottom, exceeding the height of the oil return hole, makes it difficult for the compressor to return oil, insufficient lubrication of the pump body, and wear of the pump body
