Psychrometric Saturday: Latent Heat Formula

You can use the latent heat formula to calculate how much moisture and heat in thst moisture your AC is removing.

good info, thanks

The change in humidity on the humidity ratio axis on the right of psychrometric chart gives the evaporation by multiplying with latent heat in X Joule / kg
On the left on enthalpy axis these two points give total enthalpy change dH in Joule/kg. dH is sum of latent and sensible heat
(dH - X) = Sensible heat in Joule/ kg

The true flow grid has become such an important tool now.
If you don't measure you're just guessing. Im amazed at how many times I see a 5 ton blower drive on a 3 ton system and it was left at the factory default speed.

Awesome comment

Great explanation! I know this is an example, but isn’t 55 db/55 dew, 100% humidity?

[@timdestasiohvac]

Yes that is correct.
