What is the difference between AC condenser and evaporator coils?

one is liquid and the other is gas

they are designed for different air flow patterns ... but the coils are far from the only possible cause for poor cooling

" internal coolness generator" Never heard of that.

Coils are coils, all pretty much designed for the same thing. Whether that is baseboard heat, a radiator in a car, an evap coil or a condenser coil. All designed to pass heat in some manner. Size, material, and construction are dependent on use and size.

     The evaporator coil passes air thru the coil and a fan sends it on to the building. The evaporator passes hot air thru the coil to the outside air.  The condenser is larger in homes. Grampa B

     This answer has been corrected, I had the evaporator and condenser location switched. Sorry         Grampa B

If  you place a towel below a condenser, it will become wet. Placing another towel above an evaporator will eventually dry rot.

This is not a question.  Get a job canning beans, robot.

Question and answer troll strikes again.

An AC condenser operates that fairly high temperatures with a slightly different temperature difference than the evaporator coil  and has a phase change on the Inside of the coil. The evaporator coil  operates at a much lower temperature and has a phase change on both the inside and out side of the coil.

I don't know why you make the assumptions about what any home owner thinks when their unit is not functioning properly. You have no data or reason to make such assumptions.
