So except for the Heat Q on the right, this is what we have:
[LaTeX Error: Can't write to directory] [LaTeX Error: Can't write to directory]?
The COP of the refrigerator is less or equal to
[LaTeX Error: Can't write to directory] [LaTeX Error: Can't write to directory] is ambient temp.
[LaTeX Error: Can't write to directory] is water temp.
Not sure if it's, just spitting out ideas.
