Refrigerant 404a is a blend of hydrofluorocarbon (HFC) refrigerants commonly used in air conditioning and refrigeration systems. It is a non-toxic, non-flammable, and non-corrosive gas that is known for its high cooling capacity and energy efficiency. Refrigerant 404a is widely used as a replacement for chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants, which have been phased out due to their harmful effects on the ozone layer.
R404A is a non-azeotropic refrigerant mixture without chlorine. It is a colorless gas at room temperature and pressure, and it is stored in steel cylinders as a compressed liquefied gas. Its ODP is 0, so R404A is an environmentally friendly refrigerant that does not harm the atmospheric ozone layer.
Main uses: R404A is primarily utilized as a substitute for R22 and R502. It possesses clean, low toxicity, non-combustible properties, and exhibits excellent refrigeration effects. It is extensively employed in numerous low-temperature freezing systems.
