Need Help on Comparison of R134a & R407c...
by: Anonymous

1. What is the advantages of R407c vs R134a?

2. In term of performance and maintainability which one is better?

3. Why do we need to use R407c while the GWP is higher than 134a?

Actually there's a big difference...
by: Amy

The difference is big but it's not really a performance thing.

First of all R12 is the "older version" of freon that is no longer used. Also, it was used primarily in car air conditioning.

As for R22, it is part of the new family of freon that supposedly hurts the ozone layer less than the ones before it (hence the reason why it was banned). R22 is one of the replacements for R12.
