Default Chill Out This Summer with A Homemade Air Conditioner



An interesting idea. However, I wouldn't imagine its all that cost effective. Why not buy a window shaker off craigslist for $50?

It sure dropped the temperature a LOT , I just don't think it would work that well at the air flows he shows in the Video.

If it really does work that well , then its a Good Hack..for someone without Power / air conditioner.

Perhaps blue would help the efficiency?

This is a bad idea where I am, if we don't use air conditioning to remove humidity in my climate and you have a finished basement, you'll grow a mold garden. An evaporative cooler, melting ice block, etc in a climate that isn't nearly arid is a comfort disaster in my opinion and a nice way to cause moisture issues that can damage the structure and your health.

It takes more energy to make the ICE than th cooling provided by the "AC".

How is this possible? The ice is simply a transfer medium. Where are the losses?

It's like trying to cool your house with a freezer instead of an AC.

The losses are in the freezer, 2/3 of the energy that a freezer uses are turned in to heat and all of that heat stays in the house.
A pound of ice takes 144 BTUs to melt it, Window A/C tend to be 6,000 to 9,000 BTU.

Part of the reason that I stopped using my furnace fan to move the "cool" from the basement is that the furnace fan draws 600 watts, or 2,000 BTU and that I am better off running a 600 watt air conditioner.

On that same line of thought, 144btu in the pound of ice is 42 watt hours, my window fan set on low is around 40 watts, so the heat from the fan on the bucket would have to melt more then a pound of ice per hour to not add heat to the house.

Mine does not even use as much power as it shows on the chart.
