I am making homemade ac.
I am using an ice box for it. I found the link on the internet
http://www.instructables.com/id/Cheap-DIY-Air-Conditioner/
I want to ask is
1. The fan which is used must get heated by the operation
2. This will produce a lot of heat
3. This will melt the ice or take heat from bottles used at very large rate
4. How long will it sustain????
thank you

I'm not sure what you're asking.

1) The fan will heat because it will be running but it's negligible and it definitely won't overheat because fans are built to spin and it's drawing cool air through it. This is assuming the wiring and power supply are correct. Wire it wrong and you will have a fire hazard.

2) ?

3) The ice will melt because you are drawing ambient temperature air over it. Some energy from hot air is transferred to the chilled bottles and you get slightly cooler air blowing out.

4) It's hard to say without empirical data. Depends on room temperature and the flow through the box. A few hours?

What exactly are you trying to build ? - A full-scale air-conditioner ? - Or a machine to cool the air in your apartment down ? - The two devices are not quite the same.
An air conditioner controls the humidity and temperature, and ideally, removes smells from the air by filtration. Normally, a domestic air-con fails on the latter. An air-con in a vehicle can filter the air through a carbon filter.
You can air-condition the air and WARM it. Air-con and chilling are not the same thing.
An air CHILLER will be much easier to achieve and I suspect this is what you are actually after.
On the subject of your fan, if you don't impede the flow of air through it, it won't overheat.
