/diy/ - Do It Yourself

open windows during the night to let the colder night air cool your walls floor etc.
then during the day, do not open windows, roll down any external shades you have on your sun facing windows, if you don't have them, buy them or diy. the windows need to be shaded from the outside, not the inside, preferrably the air should circulate between the shades and the window.

What is the humidity where you live? You may be able to can use a swamp cooler.

This could work. I have seen it done somewhere else.

Kind of like this, except this pumps water through an old radiator. Radiators maximize surface area contact with the air, which greatly help heat transfer.

The problem is: if you make ice for the water in your freezer, the freezer has pumped as much heat into your house as the ice will absorb heat as it melts. So, this not a whole house solution.

A swamp cooler, on the other hand, can and do cool entire homes, if you live in a moderately dry climate >>208887

The problem is, the water is not separated from the air, so any mold or bacteria that grows in the water will be pumper through your home.

But as >>208886 suggests, you may not need any active cooling if you keep the windows closed up tight during the day.

Infrared blocking window film (aka Energy Film) is an alternative to external shades.

tbh in these cases i take 2 bottles of water and place in freezer, get my fan and after i just place those 2 frozen bottles in front of fan and viola, cool air

For those of you who are a bit slow, don't fill them all the way.

This worked WONDERS for me. I used a medium-sized cooler, a $15 fish-tank pump from my local garden center (probably could've gone to a petsmart, but w/e), a fan that you'd put on a desk or table, and a spiral of copper tubing. One end of the tubing attached to the pump and the other end returned the water into the cooler.

It probably cost me $40 total, but it honestly worked better than any other knockoff a/c thing I've ever seen.

(ps - put ice and water in the cooler)

A fan with a wet towel hanging in front of it. The water evaporates and cools down the air.

Second hand a/c's are easy to find and inexpensive? I mean I did the diy before but it was still to hot.

boomp

Seconded. It'll be a bit harder to find them now that the weather is warming up but you'll still probably be able to pick up a decent used window AC for half of what you would have paid for it new.

That's a sweet design. I feel like you could easily route the water-out line back into the cooler to conserve water; just periodically adding ice would probably keep it cool.
And isn't there a risk posed by the condensation of the copper next to the electricity of the fan?

>>208919
This is a dumb idea. If this works, it's not hot enough to bother, just use a fan.

>>208903
This is what you should make. Swamp coolers cause the water to evaporate, this can actually get the air below ambient temperature if it is a dry day.

You could get a small pump to circulate the water back to the cooler. Also no, the condensation wouldn't be a problem. The air is blowing outward so any condensate would be expelled away from the fan.

These ideas are all too expensive and labor-intensive, OP. Start adding a quick cold-shower to your regimen a few hours before going to bed, and keep alternating ice-packs in and out of your freezer and shove them down your pants. Problem solved.
