azeotropic refrigerant mixture R410A is chosen to replace R22 in current stage owing to zero ozone depletion potential (ODP), offer higher efficiency, lower energy costs. However, the high global warming potential of R410A may not be suitable in future. In 1990, R32 was chosen as the alternative refrigerant for R22, but was eventually The phase-out of several common commercial refrigerants is leading building owners to look for greener alternatives.

R290 will extend the life of a system because of the lower head pressures. R290 Replacement Refrigerant requires approximately 1/3 the amount of the original charge in the system and must be charged as a liquid. R-22 topped off with Nu-22. A few days back I had a contractor perform a system check for me. I have two 15 year old 5-ton Trane units that use 7lb, 13 oz of R22 refrigerant. Both were a little light in refrigerant and the contractor topped off with Nu-22. 6 oz. in one unit and 3 oz. in the other unit. For some reason, a red flag did not go off .
