Homemade Evap. Air Cooler! - Awesome Air Cooler! - Easy DIY (quickview w/closeups)
Published 2014-07-30
Homemade Evaporative Air Cooler. Easy DIY. This "large-area" air cooler is capable of cooling multiple rooms - up to 30F lower than the initial "room temperature". Designed to be used with a standard 20" box fan. Run-time: 6-10 hours per fill-up (holds 3 gallons). all supplies are easily found at the home stores. Note: Check my youtube video page for the "extended version" of this video (includes complete building instructions w/extras). notes on construction: wood used; one 10 foot 2x3 (99.75" in total). twelve 2 1/2" wood screws. one heavy duty "CoolPad Ice" all season cooler pad. one roll (2ft by 5ft) of metal screen, called "hardware cloth". 5/8" vinyl tubing (1/2" internal diameter). 200GPH fountain pump (from harbor freight). one 2' long piece of pvc pipe (1/2" diameter). assorted pvc connectors. 1/8" drill bit for water holes. 7/8" spade bit to cut hole at top of wooden braces. one 24" long window box (7" high) from walmart. lastly, works best in semi-dry and dry climates *the drier the climate the better it performs - also, for best results, use a strong/powerful fan. tip: to dry out the cooler pad do not remove it. just shut off water pump and let fan run. it should be completely dry in 15 to 20 mins. only remove cooler pad when replacing it (once or twice a year - if you use heavy duty one). you may need to use some pvc pipe cement if there are any leaks (on non-threaded connections). about $4 a bottle. (i didn't need to use it.) you may need to use teflon tape on any connector that is threaded and leaking. cooler is totally self-contained and area around cooler stays completely dry. (ran it all day for 3 days and observed no water at all outside of the air cooler).
