Sensible and latent loads of clothes dryers
Sensible and latent loads of clothes dryers
(OP)
Hi all!
I am doing a preliminary design for a space containing a clothes dryer. Can anyone give me typical values for the latent and sensible heat given off by a dryer?
Thank you!

1350 BTU/hr as a rough guess. That's 0.4 kW and I suspect my numbers are on 'comfortably' on the high side.
I've got a Carrier design manual at home, will see if they provide any figures.

Based on four people with laundry
Natural Gas Clothes Dryer = 8 therms per month
or about 26,000 BTU/day

At something less than 400 Watts ("comfortable" allowance from TD2K's estimate), by the time you count the diversity (intermittent, infrequent operation), you really are at a trivial amount. In any event, the latent load is zero as well.
As for making the house noticeably warmer, some installations may have made mistakes - such as exposed duct runs or crawl space/basement/attic venting that can re-radiate back into the conditioned space. Or, in some cases, the dryer vent may dump onto the outdoor unit of the A/C system. Any of these may adversely affect space load.
The Carrier design books (several versions), ASHRAE Handbooks, and ASHRAE load manuals were checked before my first post. An estimate is not there - and is itself an indication of the load effect.
