Why Isn R-410A More Widely Used Today?
The transition to R-410A requires that heat pump and air conditioning systems be redesigned. R-410A is a refrigerant with operating pressures almost 50 percent higher than R-22. Because of this, a redesign of the compressor as well as other components is necessary. Additionally, since R-410A demands special synthetic lubricants for the compressor, there are compatibility issues with the lubricants, cleaners and other fluids used in the manufacturing process. All of these issues must be carefully evaluated. And, with these significant product and production process changes, testing and training must change also. Dealers must be schooled in stricter installation and service techniques required for working with R-410A units and must obtain new recovery equipment and servicing tools, as well. The Clean Air Act accommodates the magnitude of this total effort by allowing a lengthy transition period for the phase out of R-22. Another reason R-410A is not widely in use is that industry product
