[EnergyPlus_Support] Re: indoor swimming pool
Hi,
in E+ I can't find where I can insert the latent gain..Do you insert
it just like an internal gain?Is it a right approach? With DB, if
you use "detailed gains", you can insert a latent gain. The problem
is that it is no possible to assign a load: you can write a
percentage of latent, a percentage of radiant. Because it join the
latent load to an equipment. I don't know if someone can understand
my bad english..
Thank you very much,
Alice
