Refrigerant R422E


R422E refrigerant is a kind of HFC refrigerant with simple use and zero ODP(ozone depletion potential). It has the refrigeration capacity and efficiency very close to R22, has lower exhaust temperature than R22, and provides up to 8% refrigeration capacity and up to 14% efficiency than R22 at low temperature. At medium temperature and a subcooling degree of 10°F(6°C), the cooling capacity of MO29 is approximately 5% lower than that of R22, but the efficiency is comparable to that of R22.


R422E Refrigerant steel cylinder is a pressure container. Keep it away from fire, heat, and direct exposure to sunlight. It is usually stored in a cool, dry, and ventilated warehouse. When handling, light loading and unloading should be carried out to prevent cylinder and valve and other accessories from damage.


R422E can directly replace R22 in moderate and low temperature direct expansion refrigeration equipment, including commercial supermarket system, and fixed direct expansion air conditioning equipment, medium temperature and low temperature commercial and industrial direct expansion refrigeration system, such as: Catering refrigeration, supermarket display cabinets, food storage and processing, ice machine, household and commercial air conditioning, direct expansion type water cooler, etc.
