[Bldg-sim] Indirect Evaoprative Cooling

[James V. Dirkes II P.E.]

Dear Doug,
 

1.	

	I'm not familiar with EnergyPro or EQuest. (EnergyPlus is my
analysis tool.)
2.	

	I AM familiar with Coolerado.
3.	

	The key to a reasonable model, in my opinion, is to get the cooling
performance suitably high (much better than typical indirect evap) and also
the fan HP correct, which tends to be higher than an indirect evap.
4.	

	The Coolerado folk have tested the heck out of their HMX and have
very good equations for it's performance.  You might be able to curve-fit
within your software....
5.	

	Finally, Coolerado is normally a blow-through application and thus
treats fan heat differently than indirect evap.

Good luck!

Anyone have experience with Indirect Evaporative Cooling (i.e. Coolerado) in
EnergyPro or eQuest?
 
We have a an office retrofit and are trying to model and quantify the
benefits of this system in the mild San Diego climate.  
Any help is appreciated, thanks.
