There are quite a few DIY/homemade air conditioners, and air coolers all over the Internet. We’ve got directions for some of them on this site. Up until now those AC’s were more for small spaces, rooms, or cars. You might call them personal coolers.
What we have here is a Super Cooler that is capable of cooling larger rooms, or even multiple rooms. With this super cooler you can experience up to a 30 degree drop in temperature. It is portable enough to move into different rooms if need be.
Better yet make several for different rooms. They are inexpensive to make, and you’ll save a lot of money on your AC bill. You are going to love how well this works. The video below will show you how to build this super cooler.
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.
Notes on construction, and what you’ll need to make this Super Cooler:
wood used; one 10 foot 2×3 (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.
Note…The Super Cooler 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). it’s only 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).
