Product Application

As one of the most widely used medium and low-temperature refrigerants, R22 is mainly applied in household air conditioners, commercial air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freeze dryers, cold storage warehouses, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration systems, commercial refrigeration systems, refrigeration condensing units, supermarket display cabinets and other refrigeration facilities.

Chlorodifluoromethane also serves as a raw material for polytetrafluoroethylene resin production and an intermediate for fire extinguishing agent 1121. It is used as a physical blowing agent for polymers (plastics), an aerosol propellant for pesticides and spray paints, and a basic raw material for manufacturing various fluorine-containing polymer compounds.

Storage and Transportation 

R22 refrigerant cylinders are pressure vessels. Keep them away from fire sources and heat sources, and avoid direct sunlight during storage. Store the cylinders in a cool, dry and well-ventilated warehouse. Handle with care during transportation to prevent damage to cylinders, valves and other accessories.
