Hi
I am a colegous student
I study in MA grade in mechanical engineering
I want to find a proper what for simmulating air and find out effects of air conditioner system on air
I really need your help
Thanks a lot

I would say, Warm air holds more moisture than cool air, in the Atomosphere, when warm moist air hits a cold front(cold air doesn't hold as much moisture as warm) the Moisture drops(rains).

In an Air conditioning system, warm air is cooled and it "drops" as the condensing water.

I have heard people say That AC's DON't cool, they remove the Heat?

I don't think so, here's why:
When you fill a dive tank it gets warm(from compressing air), if you open the valve and release the air from the tank, it will be cold and even frost.
AC systems do both of these,
You compress the air in the outside compressor unit, that fan removes the heat from the compressing. Then inside, the high pressure is released to low pressure causing the inside coils to be cold, then with a blower fan you can circulate this cold air?
