How Have Historical Cooling Methods Inspired Modern Techniques?

Click For Summary
The discussion centers on a project involving cooling a room using ice and a fan, with a request for an introductory section for a report. It highlights that while fans generate heat, blowing air over ice can effectively cool the air. The importance of specific details, such as room size and ice quantity, is emphasized for accurate calculations. Suggestions include discussing historical cooling methods like icehouses to provide context. The conversation encourages the project creator to draft their introduction for feedback.

The fan (assuming it's electric) is a heater (if the fan is hand-wielded, then the wielder is a heater) -- if it's a 60-watt fan, it produces the same heat as a 60-watt lamp. Beyond that, you haven't said: how much ice, how big a room, starting temperature of the air in the room, etc..

Thanks!, i wrote the calculation and everything related to the project, but what i need is an introduction like general information about cooling system using fan and ice . :smile:
 
You didn't write the specific information in this thread. The general information is that blowing warm air over a block of ice tends to melt the ice while cooling the air to somewhere near the temperature of the ice. If you have a block of ice that's half the size of the room, and a big fan, the room and the melted ice (water) will soon be at a temperature not much higher than that of the inside of the block of ice, except the fan motor, which will be comparatively warm until it's turned off.

We help students, but we don't do their work for them. @JohnAna , you should make an attempt to write the intro yourself, then post it here and we may have helpful comments.

Meanwhile, other PF members please do not comments until we see the OP's attempt.
 
Why not talk about historical methods of cooling such as the traditional icehouse and transport of ice for iceboxes.

Your introduction should introduce your project saying perhaps what problem you encountered that caused you to develop this solution and then you segway into the introduction to your project in particular.
 
Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
