CoolBots(TM): Inexpensive Cold Storage

This is a great article on CoolBots. There are two corrections I would make however. One is that there seems to have been a misunderstanding that if there is a power failure CoolBot coolers can't restart on their own. CoolBots restart on their own (and remember their settings) and MOST brands of air conditioners restart on their own as well after a power failure. So... if you live in a power-failure prone area, then stick with one of the big brands of air conditioners we recommend like HAIER or GE. A few brands (including SAMSUNG and FRIGIDAIRE) don't restart automatically after the power goes out, and I think that's what might have been confused in the article. Also they reference an old 2009 analysis on efficiency of the Coolbot compared to new systems, and that was done with a CoolBot attached to a whole-house air conditioner NOT one of the new air conditioners (made after 2012 with better refrigerant and NOT a window air conditioner with one fan... it was a whole house a/c unit with MULTIPLE fans). Still this is a good article.

Low-Cost Cold Storage Room for Market Growers

This is a GREAT free publication with info on building your own cooler! I like their design! What's terrific about this is that they use a HYBRID design with fiberglass batt insulation AND rigid foam insulation to save money. If you read my cooler design article from Growing For Market, I talk about how we've seen fiberglass insulation get rot and black mold, so we tell everyone to use rigid foam insulation. But this Kentucky design uses just a little rigid foam insulation in the right place to stop condensation on the outside! THIS IS AWESOME! IT WORKS! If rigid foam insulation is expensive in your area, then this could be a terrific solution, especially if you are more comfortable doing stick-frame construction. *I would STRONGLY recommend that you use 1.5 inches of rigid foam instead of the 3/4 inches that is recommended because I think it pays off in electricity savings. HUNDREDS if not thousands of our customers have used this design by now because we actively recommend it on the phone to people with minimal construction experience.
