Description

Technical Field

[0001] The utility model relates to the technical field of liquid storage dryers, in particular to a liquid storage dryer with a gas-liquid separation function. Background Art

[0002] The receiver-drier is a special component that has been continuously improved and updated throughout the development of air conditioning. Its main functions are the "liquid storage" and "drying" mentioned in its name. It is also the "receiver-drier" involved in the refrigeration principle. The receiver-drier came into being with the development of modern refrigeration technology. In the refrigeration principle, the refrigerant (refrigerant) achieves the effect of absorbing and releasing heat through the transformation of its physical form. When the refrigerant is added to the air conditioner's sealed system, it inevitably incorporates moisture from the air and impurities from the pipes. During the physical transformation process, moisture will freeze into solid ice, blocking the airtight pipes of the air conditioning system, thereby affecting the flow of refrigerant and ultimately causing refrigeration failure. In severe cases, it may cause explosion. The function of the receiver-drier is to absorb moisture from the sealed air conditioning pipes while filtering out tiny impurities in the pipes. The receiver-drier needs to filter the refrigerant, and when filtering the refrigerant, it needs to discharge the internal degassing to prevent the gas from entering the interior of the refrigeration equipment.
