I am looking for some prety basic info about mechanical dehumidification by liquid cooled coils.
I guess what I am after is how do I achive the greatest amount of dehumidification in a unit that has a fresh air/recerc damper/preheat coil/cooling coil and reheat coil.
My train of thought is to bring the cooling as low as possible while reheating the air to a set temprature. My problem I think is the return air is around 60 and the cooling coil is only able to reach 43F in and around 55F out.
Is it correct to assum I would only be able to achive a maximum RH of around 50%?
any thoughts
