RS-44 (R424a)

[indepth]

Hello guys! (sorry for my not so good english...)

We are on a project of replacing a 25tons york split system for an hopital in my city, but the client do not want to change the fan/coil section and want to try the new R424A. Our first price was based on a full change to R410(Compressor section and fan coil), but the price is too high for them...

So we will use a R22 condensing unit retrofited with R424a...
My question is; How do R424a react in real life situation?

PS: I know its not the best solution ever...but we got to do it with the budget of the client.

It's another blend of R125 and R134a with additional HC for helping MO carry over.
They all are the same ****, mixed up in different way.
