Dear e-quest users,

I am trying to model the HVAC systems (PSZ-baseline, VAV-proposed) serving high load computer rooms by supplying "cold" air at 77 F. When I entered the zone entering min supply temperature of 77F , I get Range Checking Violation for HVAC System. It appears that supply air temperature must be within the range 35-70F. I am using high supply air temperature in order to increase recovery potential of the air side economizer. Does anyone know how can I get around this "range violation"?

I would greatly appreciate your suggestions.

Thanks

Ana
