DIY Cheap & Small Air conditioner

Hi all. This is my first instructables. Sometime in the summer is very hot and i have difficulty to be comfortable in my room. So i decided to create a Cheap & Small Air conditioner for my room. This project cost me about 10$ for the fans (Founded in a garage sale). It took me about 1 hour to built this.

- A board of wood
- 2 Fan (mind come from a garage sale i think is from a Air Hockey table, works on 120V)(10$)
- Spray Paint
- Some screws
- Screw Driver

@ auto bug. i agree dat one output fan would conserve the ice but dat would reduce the cooling of da hot ait as it may stay close to da lid as it move from entrance to exit

@rprize - Seriously?

How about directing the air onto you? Rather than cooling a room a few degrees, you might find that the cool dessicated air from a few kilos of ice will chill you quite nicely for hours....

TRY THIS

have you tried it?
i think the water will block the passage of the air.

Its called a hose, the air flows through the hose underwater, cooling the air

Umm, Your hose has nowhere to exhaust. Input to the fan must be matched to output from the fan for flow to happen. Maybe you were asleep for that physics class.

macwhiz in reply to Lion of LoveAug 7, 2011. 5:08 AM

The hose connects one fan to the other and part of the hose is underwater

great build, I don't understand the need for 2 fans though, making a series of small holes at one end for air to enter and having the fan at the other end blowing out should be sufficent

Wouldn't two fans be the most efficient and move the most air?

Lion of Love in reply to gardenwifeAug 1, 2011. 11:10 AM

Exactly. I like it, if the fans are matched. If not, one will eat up energy from the other. Nice idea.

because i like the both fan sound :P

LOL I like that answer!

more fans simply means faster cooling (and faster melting)

has anyone ever tried using dry ice?

scotshocker in reply to chrisltr22cSep 9, 2010. 3:23 PM

Dry ice would not be a smart idea because it is solid carbon dioxide and as it sublimates you would have a build up of CO2 in the room potentially causing death. In fact if I remember correctly there was an episode of one of the CSI shows where that was the cause of death.

would 2 fans be better than one?

HADJISTYLLIS says: Jan 1, 2010. 9:26 AM

You don't need two fans according to this plans

Bigdawg1955 says: Aug 8, 2009. 8:05 PM

I am curious if you would need to two fans. If you had and I would use ice packs sit raised on a platform with holes on the bottom to allow air to be drawn in from the fan on top as it pulls air from inside the box out into the room

68autobug in reply to Bigdawg1955Nov 28, 2009. 9:11 PM

that would also work

but whether all that hot air would melt the ice packs faster????

I don't know....

I like the ice with water idea...

although the ice [not in packs] is going to melt and make water anyway...

The ice may last longer if only one "OUTPUT" fan was used....

and just a hole for the hot air to enter..??
A LOT of variables there.... lol
also 12 volts is a better idea than mains power which is 230v AC in Australia.
which is DEADLY..

you should put a handle on the board so you wont have to use the cord to lift it off of the cooler. this way you wont cause unnecessary wear on the wire. good idea probably way cheaper than running an a/c

So if I make one of these, can I put a small solar panel on it to sit on the window sill nearby? Would there be anything else I would need to do to it?

prizm63 in reply to freecyclenutJun 29, 2009. 3:03 AM

when over to harbor frieght and bought solar charger for tools. this has just enough power ( in full sun) to run threw PTO plug that connected to my coolerchiller that sits on top of my cooler filled with bottles filled with ice prep ahead of time. this cooler chiller is setup for boats and rv so uses PTO plug.
