Re: Help settle this argument - Hot A/C
Remember grade-school chemistry?
Gases, in this case freon, behave according to the following formula: PV=nRT, where p=pressure, v=volume, n=equals the moles of the gas, and R=a constant (~0.81 or something close to it).
Solving for temperature gives us T=PV/nR
So with the AC being a closed system, the volume, moles, and the constant relating to the freon all stay the same, leaving the temperature of the freon to vary only according to the pressure. As the freon comes out of the compressor, it is hot beacuse it has had its pressure increased. But as it passes through the evapaorator, the line cools because the pressure has been relieved. Now even though the heater core coolant bypass heats the incoming air, the air still passes over the cool AC refrigerant evaporator line which cools it down some, but not a whole lot. This is also where the humidity condenses out of the air onto the refrigerant line and drips onto the ground.
Best I can come up with.
