WHAT ABOUT FREON??

R-22

(Pink Cannister)

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 use is increasing in developing countries, largely for air conditioning applications. Air conditioning sales are growing 20% annually in India and China. In 2012 the EPA reduced the amount of R-22 by 45%, causing the price to rise by more than 300%. For 2013, the EPA has reduced the amount of R-22 by 29%

 R-410A
(Green Cannister)
R-410A, sold under the trademarked names Forane 410A, Puron, EcoFluor R410, Genetron R410A, and AZ-20, is a zeotropic , but near- azeotropic mixture of  difluoromethane  (CH2F2, called R-32) and  pentafluoroethane(CHF2CF3, called R-125), which is used as a refrigerant in air conditioning applications. Unlike alkyl halide refrigerants that contain bromine or chlorine, R-410A (which contains only fluorine) does not contribute to ozone depletion, and is therefore becoming more widely used, as ozone-depleting refrigerants like R-22 are phased out. However, it has a high global warming potential (2088 times the effect of carbon dioxide), similar to that of R-22. Since R-410A allows for higher system efficiencies than an R-22 system, by reducing power consumption, the overall impact on global warming of R-410A systems will be substantially lower than that of R-22 systems due to reduced greenhouse gas emissions from power plants.R-410A operates at higher pressures than other refrigerants.
