Air conditioning units use two types of refrigerants, R22 and R410A refrigerant. Let us go through each of them and what are the relationship between these two of refrigerants.
R22 is a single hydro-chlorofluorocarbon (HCFC) compound. It has low chlorine content and ozone depletion potential.
R22 will no longer be manufactured from year 2010. Only recycled or remaining stock of R22 can be used.
R1410 is an
environmentally friendlier refrigerant which is Non-CFC. That meant
that, if your system ever leaks, the escaping refrigerant won't
contribute to ozone depletion!
developed as a replacement to R22, which will be phased out in year
2020 in response to international environmental concerns. It was
discovered that the commonly used air conditioner refrigerant, R22
refrigerant, has a great responsibility on the ozone layer depletion.
This bring the signing of the Montreal Protocol treaty. This bring the
creation of R410a refrigerant which does not contribute to ozone
The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987.
