The whole oil thing is a complete falacy, since if you have oil in your system by the time it is leaving the evaporator and going back to the compressor your system is already fucked anyways. And unmonitored air flow? All I'm talking about is cooling the air that is already being pulled in with your refrigeration system. Kinda similar to spraying your intercooler. Your the fuckin reason why so many sites have bad information. You dont fully know how things work and pretend you do. Do some research on refrigeration systems before you start posting stupid fucking answers. Also, the average pull for an A/C compressor is about 10hp, at least on high, although 5hp is more reasonable, so I'll give you that. Do your fuckin research! I dont have a problem if its a dumb idea but I have a problem with ignorant dicks that dont know what they're talking about, at least in this instance. You might be knowledgable in some areas R240NA but obviously not this one.
Fuck you and your whole family, asshole. I have done A/C work on and off for years and know damn well how systems work. Oil in the A/C system is used to lubricate the compressor, guess you've never replaced one on a car since you'd know you pour a few drops into the compressor before final pressurizing. That oil is thinned out when charged and circulates through the system.
Secondly, your question stated that you wanted to use intake air to lower the pressure. By doing so, you're introducing whatever is in the intake into the A/C low pressure side. Again, PCV blowby, crankcase blowby, fuel vapors vented from the tank, all this is ported into the intake on a normal car. Unless you've removed all of that you're not filtering that air at all. Doing so after the mass airflow sensor would change the overall metering, since some of it would be displaced by channeling it elsewhere.
Lastly, piping anything into the engine means it's burned in the engine, so the R134a you'd be using would be mixed into the airstream and combusted with the fuel, and though I don't know if R134a is even flammable, I know the resulting byproduct coming out the exhaust would not be clean at all.
If that's not what you meant, learn how to form clearer thoughts and type them out so other people can know what's in your feeble little brain. Seems like your problem is that you're wanting to hear the answer you've already concluded to yourself, so why look for that answer knowing that you're just going to cry about it when you don't hear it?
