McLinden Abstract This table gives physical properties, safe exposure limits, GWP and ODP for compounds that have been used as working fluids in traditional refrigeration systems or are under consideration as replacements in newer systems. WebR-22 is often used as an alternative to the highly ozone-depleting CFC-11 and CFC-12, because of its relatively low ozone depletion potential of 0.055, [4] among the lowest for chlorine -containing haloalkanes. However, even this lower ozone depletion potential is no longer considered acceptable. WebJul 12, 2024 · A 30 lb cylinder of R-22 refrigerant. Introduced in the 1950s, R-22 became one of the most widely-used refrigerants for residential cooling. Unfortunately, R-22 released into the atmosphere depletes the ozone layer and traps 1,810 times more heat than CO2. As a result, a phase-out of the refrigerant in the U.S. began in 2010. memory care buffalo mn
