Subject: [Equest-users] ERV + Evap Cooling Modeling in eQuest



Dear All,
 
I am using eQuest to model an Hotel building in a very hot, dry climate zone which is has a great opportunity for energy saving when using evaporative cooling in summer. I have modeled direct evaporative cooling for 100% outdoor air handling unit along with sensible recovery wheel to recover the exhaust air stream energy into the outdoor air.
 
When I run the model simulation and got into the "ERV Energy Recovery Summary" and "SUPL Evap/Desicant Cooling" reports, I could not interpretate the outputs to understand if the system is working appropriately or not.
 
I wonder if anyone can help me and provide me with some guidance or example on ERV and Evap Cooling systems input and control setup as well as the system output reports interpretation and what I need to do to get my model run correctly reflecting the real system operation and predicted saving.
 
- My model *.inp file is attached for your reference.
