...........even if you live in Coober Pedy. 100% of the air has no value as a refrigerant and only messes up the AC system. |
I am not trying to pull a wwest here and pose a bizarre question in the hopes no one can answer it and then I become magically superior (in my own mind).
I simply do not know what the impact is. I suspect pressure differentials between high and low would be reduced by the dead space in the system and efficiency would be compromised. I also was thinking if you start with 14.7 psi and then add the correct refrigerant amount the system may run at higher pressure?
