Comprehensive method for removing non-condensable gas dissolved in refrigerant

Abstract

The invention discloses a comprehensive method for removing non-condensable gas dissolved in a refrigerant, and relates to the technical field of refrigerant production and processing methods, in particular to the comprehensive method for removing the non-condensable gas dissolved in the refrigerant, and the method for removing the non-condensable gas in the refrigerant is divided into four independent methods and two combined methods. The method I specifically comprises the following steps: heating at constant pressure; the second method comprises the steps of degassing and membrane filtration; the third method comprises the following steps: ultrasonic degassing; a fourth method: molecular sieve adsorption; wherein the combination of the first method and the second method and the combination of the first method, the second method and the third method can also be used for removing the non-condensable gas. According to the comprehensive method, in the transferring and sub-packaging process of transferring and sub-packaging the refrigerant into another container, constant-pressure heating, degassing membrane filtration, ultrasonic degassing and molecular sieve adsorption methods are combined to remove non-condensable gas dissolved in the refrigerant.

Description

technical field [0001] The invention relates to the technical field of refrigerant production and processing methods, in particular to a comprehensive method for removing non-condensable gases dissolved in refrigerant. Background technique [0002] Circulating working medium in the phase change refrigeration process—refrigerant will inevitably have some non-condensable gas dissolved into the refrigerant working medium in the process of production and storage. The so-called non-condensable gas here refers to the relative Under the pressure and temperature conditions corresponding to the storage and use process, the gas cannot be liquefied by compression and cooling; the main components and proportions of non-condensable gases are basically close to those in the air, and the highest content is nitrogen and oxygen. Some inert gases and carbon dioxide, etc., these non-condensable gases dissolved in the refrigerant will be injected together with the refrigerant into the air-condi...

[0002] Circulating working medium in the phase change refrigeration process—refrigerant will inevitably have some non-condensable gas dissolved into the refrigerant working medium in the process of production and storage. The so-called non-condensable gas here refers to the relative Under the pressure and temperature conditions corresponding to the storage and use process, the gas cannot be liquefied by compression and cooling; the main components and proportions of non-condensable gases are basically close to those in the air, and the highest content is nitrogen and oxygen. Some inert gases and carbon dioxide, etc., these non-condensable gases dissolved in the refrigerant will be injected together with the refrigerant into the air-conditioning system, the existence of non-condensable gases is extremely harmful to the refrigeration system, it will make the system Condensing pressure increases, compressor exhaust temperature increases, energy consumption increases significantly, refrigeration effect deteriorates, and the entire air conditioning system will be damaged in severe cases
