I am simulating the air conditioning room. As for the wall boundary condition, I use the interior wall temperature and convection heat transfer coefficient h (or wall function). For the convection heat transfer coefficient h (or wall function), Normally, there are following choices:
(1) h=(k/x)*0.0296Re^0.8*Pr^(1/3) which comes from the plate theory;
(2) based on the experiment,hadj,cell=[ hMACA*(Tsurface-Treference)]/( Tsurface-Tadj,cell) in which, hMACA is the algorithm calculates convection coefficients for all surfaces based on surface temperature and the appropriate reference temperatures.
(3) wall function

So I want to know which choice is better for the air conditioning room simulation?
