[Equest-users] Complex chiller/heat recovery/heat pump to model question

[Paul Brooks]

I am modeling a building in Uruguay that has a Trane 165 ton Air cooled chiller, (RTAD 165 SE, not available in US.)  In addition to air-cooling, the chiller has a heat exchanger to recover heat for whatever use you want.   Obviously the heat recovery means that in the right condisitons the condenser fans will not run as much.

For this application, the heat is to be recovered to provide heating hot water VAV box re-heat coils.  In addition to this, there are two air cooled heat pumps (CXAN 214, not available in US) that are available to augment the chiller or the hot wateer loop.

So, my dilemma, is how to model this in eQuest. I am still more or less a novice user.  I am in the detail mode, and see that I can do some things with condenser water, but then how do I model the condenser fans?  How do I tie in the heat pump loops?

Lastly, this is a LEED model.  So, any thoughts on how to get data and then do hand calcs to prove savings are also welcome.    

Thanks!

If interestede in seeing info on the equipment, go to Trane-eur.com.  information is available in english for these models. Your local trane rep will probably not be able to help.
