I would like to know your opinión and knowledges...about turn R-410a of a system to R-407c.
thats is a simple requirement of a customer, and i prefer know about to use same oil.
As far i know it is compatible but i dont know if is necessary any element like dryer filters...
i hope you can post here...and let me know your position about that...
Just from a casual glance at the ASHRAE Handbook, Fundamentals it looks like R-407c may be more effective than R-410a. However, pressure/enthalpy diagrams are different which means that the existing system may have to be significantly altered. You know more about the system than I do, work through the equations and determine what needs to be changed.
