R-134a is the most widely used medium and low temperature environmentally friendly refrigerant. Due to its good comprehensive performance, R-134a becomes a very effective and safe alternative to R-12. It is mainly used in most of the use of R12 refrigerants.
R-134a (1,1,1,2-tetrafluoroethane) is a kind of non-chlorine atom, does not damage the ozone layer, and has good safety performance (non-flammable, non-explosive, non-toxic, non-irritating) , Non-corrosive) refrigerant, its cooling capacity and efficiency are very close to R-12 (dichlorodifluoromethane, freon), so it is regarded as an excellent long-term alternative refrigerant.
Refrigerant name R-23 Molecular weight 70.0 Boiling point (1atm), ℃ -82 Critical temperature, ℃ 25.9 Critical pressure, kPa 4836 Saturated vapor pressure (25℃),
R23 refrigerant, alias Freon 23, F23, F-23, HFC23, HFC-23, trifluoromethane, trade names are Freon 23, Genetron 23, etc., Chinese name trifluoromethane, English name fluoroform, Trifluoromethane, chemical formula CHF3. Because R-23 belongs to HFC substances (non-ODS substances Ozone-depleting Substances)-it does not destroy the ozone layer at all.
A member of the R22 Freon family, R404A is an environmentally friendly refrigerant. A member of the R22 Freon family, R404A is an environmentally friendly refrigerant. A member of the r22 Freon family, former physics teachers said it would destroy the ozone layer. It is rarely used in developed countries. China will also completely phase out and ban the use in 2030.
Trifluoromethane Chf3 Refrigerant Gas R23 is your good choice. R23 is a widely used ultra-low temperature refrigerant. Due to the good comprehensive performance of HFC-23,
