Select for dehumidification or cooling?
Select for dehumidification or cooling?
(OP)
Does anyone know what criteria to use to select an air handler for either cooling or dehumidification? I used two design conditions using ASHRAE Fundamentals handbook.
Thanks
Thanks

High sensible loads = lots of air and shallow coils
High latent loads = less air and deeper coils

Remember that the ASHRAE design conditions aren't necessarily "real". They result from a lot of statistical mumbo-jumbo over a large number of years of data.
Use an hourly data set like TMY and see how many hours per year each equipment selection will operate in an unsatisfactory way. Maybe tweak the selection a bit and try again.
It's an engineering judgement thing.
