Verusamore Posted December 20, 2004 Posted December 20, 2004 Hi , Guys its getting here being summer and I was thinking if there were any alternatives to building my own little air con system without the cost and bulk of normal systems , does anyone have a clue building cool air conditioning system without the fuss of spending 100's of dollars . The size doesn't matter but in preference a miniture size system would be swell . Thanks .
YT2095 Posted December 21, 2004 Posted December 21, 2004 buy a second hand chest freezer, and with a litle metalwork skills you can turn it inside out. then all you`ll need a fan next to the cooling elements and the heat excahnge and evaporators can go outside
Nave Posted December 22, 2004 Posted December 22, 2004 take a look at http://home.howstuffworks.com/ac2.htm. This gives you a basic understanding of how one works. You could prob take the parts off of some old freezer thats someones throwing out..good luck
TerrysID Posted June 14, 2005 Posted June 14, 2005 Before car A/C's, a cylinder of ice was attached to the slit of an almost closed car window--air would blow thru ice into window slit and cool car. A fan on a block of ice aimed at you should work a little.
H2SO4 Posted June 14, 2005 Posted June 14, 2005 take a cooler and cut one intake vent into the lid, and another hole for a fan. Fill with ice and close. Turn it on and and you got a simple AC. Seeing this thread makes me want to take apart an old minature freezer (maybe, if im careful, not break any of the evaporator joints) and make an ac.
Phi for All Posted June 14, 2005 Posted June 14, 2005 Let's not forget swamp cooling. A fan behind a porous padding which is moistened by a recirculating pump. Cool and no ice to melt. Humidifies dry air too. Go swamp!

Mr Skeptic Posted February 29, 2008 Posted February 29, 2008 You may consider buying a new one -- the costs for the air conditioner will probably get far outdone by its energy usage.
insane_alien Posted February 29, 2008 Posted February 29, 2008 covering your house in tinfoil would reflect a lot of the radiation. keep your place nice and cool. though seeing as this is a 2005 thread, doubt the OP is around anymore.
CaptainPanic Posted March 3, 2008 Posted March 3, 2008 Air conditioners are the biggest waste of energy I know of. Please consider buying a commercial one, because the chance is that it's more efficient. When you definitely want to build one yourself, at least make a rough calculation of the price of the energy it will require. Yes, I am one of those treehuggers that wants to save the world, and I frown upon people with air conditioners.
YT2095 Posted March 3, 2008 Posted March 3, 2008 that`s Easy then, get yourself a large stainless steel drum (like the sort used for boiling water in canteens), then fill it with ammonium nitrate. slowly drip water into this, it will Freeze! then all you need to do is rig up a solar powered fan. when it`s all used up, pour the slurry into a large shallow tray and leave it in the sunshine to evaporate all the water off and recrystalise. it`s ready to use again and if That`s not green enough for you, throw the AN over your lawn and wait, it`ll be like Vietnam within a week or 2 Happy now?
Riogho Posted March 4, 2008 Posted March 4, 2008 Do you have any idea how much ammonium nitrate that would take? 1kg of NH4NO3 will dissolve in about 1 liter of water... it will take about 28kj of heat from it's surroundings.
security030 Posted November 26, 2008 Posted November 26, 2008 Yes here the site which can help you in air conditioning
