Hello RE fans,

I'm involved with maintenance and such in a campus type environment with many buildings. New HVAC installations have "enthalpy wheels" that transper energy from exhaust to supply. Does anyone know where or if there are standards for the placement of temperature and RH sensors? Especially on the supply duct. The design I've inherited has them down stream of the wheel. Would it not make more sense to have it upstream of the wheel? Thanks, Joe.

Was very interested in this one Brian

'Enthalpy wheels' have not come across before

for some reason (maybe my end) the doc keeps locking up on me & I need the task manager to close it !
