R22:
◆R22 is a medium temperature refrigerant, its standard boiling point is -40.8°C, water solubility in R22 is very small, and mineral oil mutual dissolution, R22 does not burn, does not explode, toxicity is very small, R22 penetration ability is very strong, and leakage is difficult to find. Widely used in air conditioning, heat pump, dehumidifier, freeze dryer, cold storage, food refrigeration equipment, Marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensing unit, supermarket display display cabinet and other refrigeration equipment.
R134a
◆ R134a as an alternative refrigerant for R12, R134a has very low toxicity and is not flammable in air. Widely used in: refrigerators, freezers, water dispensers, automobile air conditioning, central air conditioning, dehumidifiers, cold storage, commercial refrigeration, ice water machine, ice cream machine, refrigeration condensing unit and other refrigeration equipment. Everything has a good chemical stability, however, because of its higher water soluble, so adverse to the refrigeration system, even if there is a small amount of water, under the action of lubricating oil and so on, will produce a acid, carbon monoxide, carbon dioxide or to metal corrosion effect, or "copper" effect, so everything on the system of the dry and clean even more demanding.
R404A
◆ R404A is a mixture of HFC125, HFC-134A and HFC-143. It is a colorless gas at room temperature and a colorless transparent liquid at its own pressure. It is a non-azeotropic refrigerant without chlorine. Suitable for medium and low temperature new commercial refrigeration equipment, transportation refrigeration equipment and refrigeration equipment. R404A is mainly used to replace R22 and R502. It has the characteristics of clean, low toxicity, non-combustion and good refrigeration effect. It is widely used in low temperature refrigeration system. Its ODP is 0, so R404A is a refrigerant that does not destroy the ozone layer.
