Re: OK you psychrometric guys with calculators on your belts
I think you're getting so focused on the ambient temperature and RH values its really confusing you on what causes things to dry. You can have a great difference between outside and inside and make the conditions suitable for drying, but the key to drying is creating a difference in vapor pressure between the material you're drying, and the drying environment.
Higher vapor pressure wants to go to lower. So while your drying environment might be lower than the outside, the outside is trying to come in(in the summer), not the other way around, so exhausting it isn't going to do much for you, so you need dehus. In the winter its perfect conditions for an exhaust system, because the vapor pressure outside is going to be significantly lower, even at a high RH, even cold. Bring in cold dry air, still get heat to the rugs, exhaust it out.
In the summer you're going to want to create a chamber, lower the RH, and significantly raise the ambient temperature(70's would be okay 80s ideal), via dehumidifiers. Then you're going to want to raise the temperature directly at the material(rugs) even more(output of the dehu = 95-105 degrees, or an e-tes unit).
Its going to take "more work" in the summer to dry the rugs than in the winter(should dry real quick), but its definitely do-able.
Man I miss living in Utah, it was so easy to dry out there.
