HVAC modelling
Dear All, Anybody here has experiance on HVAC CFD modelling. In my model I am not able to model heater core and evaporator. What is the general practice? How they are modelled? From literature it is clear that they are given porous media properties for pressure gradient and heat source/sink for temperature characterization. From experimental data I have calculated alpha and beta for pressure gradiants (porous media) but I am not able to do temperature characterization. I have relation between delta T and normal velocity through both HEs. i.e. delta T acros HE = f (v) where f is second order polynomial.

Please guide. Thanks Ash

Re: HVAC modelling
Use the sorent.f subroutine to model the heat flux in the heater core.
