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. |
