[EnergyPlus_Support] Ideal Loads Latent Cooling Rate

["simonflorian2002" <f.simon.mail@xxxxxxxxx>]

Dear E+ User,

I have some difficulties to understand how is calculated the latent Energy/Rate for Ideal Loads air System. I'm using such a system, with humidification and deshumidification set to none, and yet, I found a "Ideal Loads Latent Cooling Rate". I thought that, with this setting, the sensible and latent cooling rates are the same, why are they different ?

Thank you.
Florian
