Re: [EnergyPlus_Support] Question about "People latent"

I read the below article in regard
to people latent heat gain.
But, i wondered about a latent load of people as before.
How does a ratio between a sensible load and a latent loade
determinate in the EnergyPlus?
do you refer a ashrae data or calculate a latent load according to
human's activity ?
I am working on the Engineering Doc write up for this. It's out for
review right now and I should be able to post it (attachment as a
Microsoft Word article) in the next day or so.
The sensible load calculation is based on a correlation fit to data
published in the 1965 Handbook of Air Conditioning System Design
published by Carrier. The latent is then the total -
sensible. "a fit to the data at average adjusted metabolic
rates of 350, 400, 450, 500, 750, 850, 1000, and 1450 Btu/h each at
temperatures 70, 75, 78, 80, 82 F. Sensible gains of 0 at 96 F and
sensible gains equal to the metabolic rate at 30 F were assumed in order
to give reasonable values beyond the reported temperature
Hope this helps until the excerpt is given.
