Hi Allison, 
Very good article, with just the right amount of detail to explain the underlying concepts and illustrate how an air conditioning system works.  
This article is over 3 years old so I don’t know if you are still accepting comments, but I have a question related to the photo in your article where ice has formed on the suction line. You mentioned that this is a sign of a problem, and in fact this happened to my ac system once when I ran low on refrigerant. I’m having trouble understanding why that happens. Intuitively, I would think that the less refrigerant in the line, the HIGHER the temperature would be and the less likely it would be to form ice. Unless it has to do with pressure: the less refrigerant in the lines the less pressure there is and it can’t get hot enough to keep ice from forming (higher pressure = higher heat, right?). Any explanation you can offer would be appreciated. 
Thanks, 
Mike

Everything that is lost in the 2nd law can be found hiding in the entropy.

Due to alot of thermodynamics I have decided I can’t live any longer with out it. I’ve tried my best and no matter what I have done,… It always gets to me and burns me up!  
 
 
 
Good explanation of the magic of cool/AC! Now if I could only get someone to explain to me on how to still be cool at my age as you can see by this post, Lol. 
 
 
 
Thanks AB3!

Carl: The second law of thermodynamics is one of the most important principles of all. You have to be a little careful about how much you say, though. Too much thermodynamics has been known to lead to suicide.  
 
Tom: Glad you liked the article!

I evoke the second law of thermodynamics in all of my discussions with my customers. It really helps them understand how their home works. 
 
Keep it up
