Refrigerant Gas R-22 Packed in 13.6kg Cylinder with Purity Over 99.97% From China Factory Directly

GENERAL DESCRIPTION
Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22. It is commonly used as a propellant and refrigerant. These applications are being phased out in developed countries due to the compound's ozone depletion potential (ODP) and high global warming potential (GWP), although global use of R-22 continues to increase because of high demand in developing countries. R-22 is a versatile intermediate in industrial organofluorine chemistry, e. G. As a precursor to tetrafluoroethylene. R-22 cylinders are colored light green.

As an additional environmental concern, R-22 is a powerful greenhouse gas with a global warming potential that is 1810. Hydrofluorocarbons (HFCs) are often substituted for R-22 because of their lower Ozone Depleting Potential, but these refrigerants also have high global warming potential. R-410A, for example, is often substituted, but has a Global Warming Potential of 1725. Another substitute is R404A with a Global Warming Potential of 3900. Other substitute refrigerants are available with low Global Warming Potential. Ammonia (R717), for example, has a Global Warming Potential of < 1 and is a popular substitute on fishing vessels. Propane (R-290), is another example, and has a Global Warming Potential of 3.
