Main uses of R-404A
R404A, as a widely used medium-low temperature refrigerant, is often used in cold storage, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration and transportation refrigeration equipment (refrigerated trucks, etc.). ), refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.
Refrigerant R404A is the most common industrial standard refrigerant (usually low temperature refrigeration system), which is used to replace Freon R22 and R502 in newly installed refrigeration equipment. R404A is closest to the operation of R-502, and is suitable for all environments where R-502 can operate normally. R404A has been recognized and used by most refrigeration equipment manufacturers in the world.
However, R404A is different from R502 and R22 in physical and chemical properties, theoretical cycle performance and compressor oil. R502 and R22 can only be added for after-sales maintenance of refrigeration equipment with newly installed R502 and R22 refrigerants, and R404A cannot be directly used to replace R502 and R22 (that is, it is usually impossible to replace them with blood exchange).
