Though, the use of R22 gas in refrigeration systems as refrigerant can be used further. However, the use of R22 in virgin form is banned and there would not be any maintenance or servicing practice. By the way the production of R22 as refrigerant has been stopped officially, so no new refrigeration system will be entertained that uses R22 refrigerant.
In a little while by the year 2015 the components like R22 are going to be eliminated from open use because of its adverse impact on the ozone layer and environment. However, throughout the 20th century the fluorocarbons mainly the chlorofluorocarbons are commonly used in our refrigeration systems. But soon by the year 2003 it is noticed that the components like R22 are proved to be very harmful for the nature and is the prime cause for the ozone depletion and global warming.
It is observed that the use of R22 refrigerant gas or chlorofluorocarbon brings about the mass ozone consumption impact and there are many different refrigerants that are safe for the environment purpose are available and may be used as the alternative to the R22.
Components like Alkali, sulfur dioxide and non-halogenated hydrocarbons, for example, propane are few different refrigerants that are safe to use concerning the environmental issues and could be used as the replacement to the monochrome R22.
The components that are ideal and safe for the replacement of R22 as refrigerant are those that have thermodynamic properties and non-destructive to mechanical components. The likely, replacement to R22 refrigerant are those components that are free from toxicity and flammability. All in, the replacing refrigerant must not carry any harmful effect that is liable to cause global warming and ozone depletion.
