Differences between R410A and R22 Refrigerant |
• It operates in same temperature range as R22. • It operates at 60 % higher pressure than R22. • It uses POE oil instead of Mineral oil as in the case of R22. • R410a is HFC (hydro fluorocarbon) while R22 is HCFC (hydro chloro fluoro carbon ). • R410A has zero ozone depletion potential because it does not have any chlorine atom while R22 is not safe for ozone layer because of the presence of chlorine. • Temperature glide of R410A is .2 while that of R22 is zero. • R410A has GWP of 1975 while that of R22 is 1700. • R410A is more energy efficient (about 5 %) than R22. |
