[EnergyPlus_Support] Re: Humidifier Control

["Elmer Morrissey" <elmofuddly@xxxxxxxxx>]

I found one problem with the file, it seems that the 10 KW latent gain
in the zone causes the major problems. To simulate a 10kw latent gain,
I have used the HOT WATER EQUIPMENT object and put in 10000W with 1.0
for fraction latent. Have I missed something about why I can't use
this object in this way? Is there any other way to introduce a 10kw
latent load without disrupting a humidifier's control?

Kind regards

-Elmer
