Supply of environmentally friendly refrigerant R134A

Refrigerant R134a: the formula CH 2 FCF 3 (tetrafluoroethane), the boiling point of a molecular weight of 102.03 -26.26 ℃, freezing point -96.6 ° C, the critical temperature of 101.1 ℃, the critical pressure of the saturated liquid density 4067kpa 25 ℃, 1.207g / cm 3, liquid Specific heat 25 ℃, 1.51KJ / (Kg · ℃) Solubility (in water, 25 ℃) 0.15%, the critical density 0.512g / cm3 ozone depleting potential (ODP) 0, global warming coefficient value evaporated under (GWP) 0.29 boiling point Potential: 215 kJ / kg quality indicators purity ≥ 99.9%, moisture PPm≤ 0.0010, acidity PPm≤ 0.00001, evaporation residue PPm≤ 0.01 R134a as refrigerant R12 replacement, many of its features very similar to R134a and R12 very toxic Low, non-combustible in air, safety category A1, chemical stability is very safe refrigerant R134a well, but because of its aqueous solution is higher than R22, so the refrigeration system disadvantage, even if the presence of small amounts of water, in the role of lubricants, and will produce acid, carbon dioxide or carbon monoxide, it will produce metal corrosion, or have a "copper" effect, so dry and clean R134a R134a system requirements are higher for steel, iron, copper, aluminum and other metals found no chemical reaction with each other phenomena, only a slight effect of zinc Packing cylinder packing 800kg / 800L, 400kg / 400L, 50b / 22.7kg, 30b / 13.6kg, 250g cans use R 134a is internationally recognized One alternative to CFC-12 main refrigerant commonly used in car air conditioners, commercial and industrial refrigeration systems, as well as a blowing agent for rigid plastic insulation materials production, can also be used to configure other mixed refrigerant.
