ok I see some of u misunderstood slightly, the reference to R12 is only as an example
for eg the old R12
to demonstrate that different gasses are more or less efficient and require different operating conditions to perform as intended. I specifically asked for gasses compatible with the existing oil, I know R12 is not.
I was asking about the topping up as a 'what if' kind of question. There is no current problem but I may have to open the system to perform some modifications so this is just foward planning since depending on the gas I put in now it may make upkeep simpler or less costly later on.
cool, can u tell me some more about 415 and 406 gasses, pros cons, how does a system with these gasses perform in comparison to 134a. u are saying that u just cannot top up with 415 and 406? Is this because when the gas leaks it may not leak in equal proportions to the original mix?
I have been observing an 'A/C technician' at work and he just mixing gas like a mad scientist, it didn't look right but he said 'it go work', one of the statements I fear most from the trini crackshot, anyway some more input from those in the know is required.
