Solar Kiln in a Humid Climate7/2
First of all, I would like to thank you for your many contributions I have come across at Woodweb.com! Thank you so much for sharing your wealth of knowledge with us.
I have been milling live edge slabs and will soon build a kiln. I am looking into the feasibility of dehumidification, solar, or a combination of the two. In San Antonio, TX we have a wealth of solar energy at 29.5 latitude. However my concern is that our average relative humidity is too high at 67%. Do you think this would be significant in slowing down a solar kiln? Do you know of any similar climate solar kilns I could get info from?
Lastly, if I do 100% solar, do you know anyone who would want and compiles data about solar kiln performance similar to the data listed in your kiln design articles here on wood web.com?
P.S. Having finished writing this, I guess I should post it in the forums so that others can contribute as well as benefit from the information shared.
If You heat foggy air by 25 F, then the humidity would be under 30%RH. So, you do not need to worry about high RH. In fact, much of the US is about the same average RH. Start the kiln fans at about 9AM and turn off about 9PM.
The humidity won't be a problem because if the raise the temp, the RH and EMC drop. For example, if you have 95F/67% air and heat it to 120F, the RH will be about 35% and the EMC will be what you need. There will be other issues but that isn't a concern as long as you can keep it hot
