[EnergyPlus_Support] Re: Water Use Equipment as mister simulation

["bish.dj61" <bish.dj@xxxxxxxxx>]

hi All
Just a further update on this. I have tried all sorts of things to 
get the latent heat gain to actually affect the temperature in the 
zone of interest without success. I considered that the air 
infiltration rate was too low so that once the humidity reached a 
high value no more could evaporate, so the latent heat gains couldn't 
actually reduce the mean air temperature. I tried upping the 
infiltration rate, but it didn't really affect the temperature 
besides what I thought was just transferring more of the outside are 
to the inside. 

Anyway, if anyone could inspect my idf (Market export to E+ H20 use 
equipment - Jan 30) and see compare the mean air temperature with and 
without the water use equipment, and see why I don't see a difference 
in the temperature that would be great!

cheers, and avva good weekend,
Danny
