Yeah, that's a great way to look at it, kind of through an '
exergy' lens... using the appropriate heat energy (or in this case 'cool energy') at different steps as the energy cascades it's way down to an unusable entropy level.
That's a very sophisticated approach. There is even a book that is no longer easy to get called, "
Low Temperature Heating and High Temperature Cooling REHVA Guidebook". You might be able to find it in libraries somewhere (inter-library loan). There was considerable work done on this front in Europe. A consortium called LowEx was formed and there was a broad effort to get other countries involved, including the US, who declined to get involved (you can lead a horse to water, but it's still a horse).
As far as I can see, the Europeans have internalized the lessons learned and are applying them to their approaches to heating & cooling.
I started a
thread on EcoRenovator as a repository for information and discussion on this topic. The entry that has the most useful links to information is
HERE.
I have searched for and found papers that detail '
Exergy Analysis' of heating and cooling projects. Most of the papers I have found at the time of my searches seem to come from Germany, Denmark, India and China.
