Comparison of Dehumidifying Refrigerants and other Refrigerants

Refrigerants for commercial refrigerant dehumidifiers:


R22:R22 is a medium temperature refrigerant with a standard boiling point of -40.8 degrees Celsius. The solubility of water in R22 is very small. It dissolves with mineral oil. R22 does not burn or explode. It has little toxicity. R22 has strong penetration ability and is difficult to detect leakage. Widely used in air conditioning, heat pumps, dehumidifiers, freeze dryers, refrigerators, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensation units, supermarket display cabinets and other refrigeration equipment.


As an alternative refrigerant to R12, R134a has very low toxicity and is nonflammable in air. It is widely used in refrigerators, water dispensers, automobile air conditioners, central air conditioners, dehumidifiers, refrigerators, commercial refrigeration, ice water dispensers, ice cream dispensers, refrigeration and condensation units and other refrigeration equipment. The chemical stability of R134a is very good. However, because of its high water solubility, it is not conducive to refrigeration system. Even if a small amount of water exists, under the action of lubricants, acid, carbon dioxide or carbon monoxide will be produced, which will corrode metals or produce "copper plating" effect. Therefore, R134a requires higher drying and cleaning of the system.
Other refrigerants:


R404A is a mixture of HFC125, HFC-134a and HFC-143. It is a colourless gas at room temperature and a colourless transparent liquid under its own pressure. It is a non-azeotropic refrigerant mixture without chlorine. It is suitable for new commercial refrigeration equipment, transportation refrigeration equipment  and refrigeration equipment of medium and low temperature.
R404A is mainly used to replace R22 and R502. It is clean, low toxic, non-flammable and has good refrigeration effect. It is widely used in cryogenic refrigeration systems. Its ODP is 0, so R404A is a refrigerant that does not destroy the ozone layer in the atmosphere.
