Hello, Garveydai<br><br>Your question could be a simple or/and a complex one!<br>In trying to give you an answer, it seems, that you want to know what's inside the box, I mean the equipment engineering, itself. If it's that so, first, prepare yourself, for learning something more about thermodynamics, fluidmechanics and some heat-transfer basics, before you enter in some specialized reading about chillers. <br>Of course, you can go up-side-down, but you should have a very good balance, in order not to get lost, and not having more doubts, than at the beginning of the process. <br>Any way, some easy manuals from ASHRAE (take a look to the netsite), Air Conditioning Manual by CARRIER Int. Ltd or Refrigeration & Air Conditioning, by W.F.Stoecker and J.W.Jones (ed, McGraw-Hill) will give you a lot of help.<br>Good luck and work!<br>Rapossos <br><br>
