Next, show me where anything I've stated in this thread goes against
the laws of thermodynamics. I'll be waiting for that, too. Unless you
want to admit you don't know what you're talking about. One of the
other.
Here it is again in case you missed it the first time-


" So, you do realize that that water, in order to cool with any noticeable
amount, would be quite warm, usually warmer than the ambient air
temperature, don't you?"

So, please explain how the cold water in the heat exchanger becomes warmer
than the ambient air.
I'll be waiting.

IN
Uh, perhaps by EXCHANGE of HEAT?
Now, please show which law of thermodynamics I've broken by what I've
stated.


In this type of system, where the working fluid does not undergo phase
changes or significant changes of pressure during it's cycle, it would
be impossible for the working fluid to become warmer than the ambient
air temperature and still cool the ambient air. Doing so would violate
the 2nd law of thermodynamics. One of the many equivalent statements
of that law is by Clausius, which is "Heat cannot of itself pass from a
colder to a hotter body."

For this system, if the working fluid became hotter than the air and is
still cooling the air, then heat is passing from a colder to a hotter
body, thus violating the 2nd law.

Trust me on this, you are talking to a brick wall.
