Hi I am a new member and mainly i need info about how to replace used ***** in a cycle not technical info but scientific as an example why we can replace r22 with r 134a on what basis did we do that?
that was my first question i will sort the rest and i hope to find suitable answers
when the ***** acts to be corrosive ? i heard that some *****s are corrosive for rubber for example.
what are the basics we choose lubrication oil in the compressor and motor? some time it reacts with ***** so how to avoid it .
how to measure the ***** flow rate in the cycle?
as there are methods to save energy through controling the compressor work which is proportional the mass flowrate through it.
if any one got any answers i will be greetful.
SORRY FOR DISTURBANCE AND BAD ENGLISH.
