DIY Air Cooler! AC Air Cooler with "chilled Water" - Powerful! Heat Exchanger w/fan! Easy AC! Solar

Описание: Homemade AC Air Cooler! DIY "Water-Chilled" AC Air Cooler! w/motor speed control! simple to build! full instructional talk-thru in video. made with an 8x8 "water-to-air" heat exchanger, small water pump and a 7" fan. This new design cools air by pumping ice-water (or cold water) thru a water-to-air heat exchanger (copper/aluminum radiator) and then drawing the warm air thru the unit using a 12v radiator fan. the air that is produced is cooled dramatically with no increase in humidity and no need to vent any part of the unit to the outside. the heat is essentially captured into the cold water and the "cold" in the water is released into the room as cold air. tests... with water temps around 45F (7.2C), i was getting 55F (12.7C) output air! (at 1500 CFM air flow!). highest temp i saw was 63F (using no ice, only cold water). the unit easily cools living space in no time at all. i was amazed at it's efficiency. unit ran for hours on one fill up of ice and water. note that no ice is even needed... just cool water. unit dropped air temp in room from mid 80's to mid 70's (29.4C to 23.8C) and below. *in certain situations it can be too cold to sit right in front of it for an extended time. notice the scene where i put on a coat. that was not meant as a joke or over-statement. after filming in front of the unit for hours i was actually shaking a little. at first i thought i was hungry or getting sick or something - then realized it was the air cooler so i put a coat on to warm up. note that this device can be used as a heater too! *with no modifications. all you have to do is pump warm/hot water thru it and it produces warm/hot air! (up to 25,600 BTU! per manufacturer). main parts needed... 8x8 heat exchanger (on amazon for $44.00), 7" 1500 CFM radiator fan (on amazon for $14.00), 12v water pump (amazon 10.00) and a couple of scrap pieces of wood and plastic pipe. goes together in minutes. portable and versatile. can be used with an ice-chest/large plastic tub or just fill kitchen sink or bathtub. then place tubes and pump in basin and set the unit on a counter top, table or chair. fill basin with hot or cold water and fire it up. if you naturally have cold tap water you can essentially run this thing continuously for next to nothing. calculated costs to run this over 30 days at 10 hours a day are... 54 cents for the pump (12w at 15 cents a kwh). extra cost to run your kitchen fridge to freeze the ice... about 1.50 to 2.00 for the month. 12v fan on solar so the total cost is about $2.50. (or essentially free). i highly recommend this project as it is very powerful and can be used in a variety of ways. *as both cooler and heater. badger-pipe makes/sells the heat exchanger but i recommend getting it on amazon. they sell it there - only $44 (and no tax or shipping when i bought it - just a straight 44). any 7" radiator fan should work with this project, and then just chose your pump (AC or DC) and pipe. i recommend at least using a 200 gph or higher (300 or 400 one would be good too). i just bought a 350gph 12v bilge pump. i'll try that and compare temps. so far i've run it partially solar powered but using a 12v pump makes the unit itself 100% solar powered. pipe i used is rated from (minus 40F) to 175F (so will work for cooler and heater option). optional motor speed control unit from amazon (12.99)... Final thoughts, i recently bought an anemometer (wind speed meter). the 1500 cfm from seller is accurate. i measured airflow anywhere from 1200cfm to 1800cfm. (depending on where you hold the meter). so the average would be about 1500. also checked the wind speed. it averages 20 mph! (32.19 kph). for the longest run-time between fill-ups start with cold water from your fridge versus tap water. just keep a few gallons of water in your fridge and use them at startup (along with the ice). fridge cooled water will be around 40F and will melt the ice way slower than if you start with 75-80F tap water. the warm tap water will eat up a third of the ice just to get the water to 45F. *for max. cooling optimal water temps (per online research) is 39F to 44F). i noticed that the output air seemed to generally be 10 degrees warmer than the water (water temp 45F then air temp about 55F)
