Air Conditioning with no Energy?
Answer:
Simplified evaporative cooler:
Window fan, heavy towel, large pan, bucket with a small hole.
Arrange the fan to blow at the towel hung on a rod. (not on the fan... we don't want to cause an electrical fire)
Hang the bucket so the hole dripps on the towel.
Put the large pan to catch water that doesn't evaporate off of the towel.
That can cool a room by 20 degrees if you live in an area with low humidity. It won't help at all if you have high humidity.
create evaporative cooling on yourself!
mist yourself down with a hand sprayer
get some kind of air circulation going, open a windows on both the north (cool) and south (hot) side of the house.
if you live in two story house, open windows on lower story only on south side, and upper story windows only on north side, this will create a natural suction of air currents that will cool the whole house.
You could go to your local pharmacy and purchase the hand fans that come with the squirt bottle they stand up so you could but it buy the nightstand.. if not my friend has used the sun shades for your car-- it keeps heat from the sun completley out. just stick them on the windows and it should work.. finally if nothing else works just go to amazon and buy a used fan for .2 cents
Cooling down without paying up.
Hanging an awning
The theory behind awnings is simple. They create shade, usually on the outside of windows, by blocking direct sunlight. A properly installed awning can reduce heat gain by 65 percent on southern windows and 77 percent on eastern windows, the DOE says.
Cover the windows
Although covering the interior of windows is not as effective as exterior shading at blocking the sun, it still is worthwhile.
One of the most efficient, if not gorgeous, window coverings is a heavy drape or curtain. The tighter the curtain is against the wall around the window, the better it will prevent heat gain.
Ventilate
"Houses should breathe," says the hometips.com Web site, and adds that "some experts recommend that one half of a home's air volume should be exchanged every hour."
To get these zephyrs moving, you should open windows at the lowest and highest points of the house and keep interior doors open. This is known as "thermosiphoning." It makes use of the principle that hot air rises, pushed up by cooler air.
There are a couple of caveats to natural ventilation. This technique works best during the coolest parts of the day and night. During the hottest part of the day, the thing to do, according to the DOE, is to seal off your house from the sun. Moreover, when the humidity becomes excessive, opening windows and doors does not bring much comfort.
Turn on a fan
Back when President Jimmy Carter urged us to save energy by turning office air-conditioner thermostats up to 78 degrees, government comfort gurus stated that we could tolerate a warmer room as long as the air inside it kept moving. In other words, if you turn on a fan, you might not have to turn on the air conditioner.
Simple $20 box fans, the ones shaped like rectangles, do a very good job moving air. Secured in an upstairs window and blowing out, they can speed along the aforementioned thermosiphoning process.
They are cheap to operate. "A standard box fan will use less than 100 watts a day, whereas the smallest window air-conditioner units (5,000 BTU) will use 500 watts or more," says a spokeswoman for Lasko Products, a West Chester, Pa., fan company.
A box fan also can be used to create a "homemade" air-conditioning system. Among the tips I read online was one that explained how to survive a heat wave without air conditioning. "Sit in the path of a box fan that is aimed at an open cooler, or a pan filled with ice," medicine.net advises.
Hug a tree
Shading your house can reduce indoor temperatures as much as 20 degrees, according to the federal government fact sheet "Landscaping for Energy Efficiency." The most thermally efficient trees are deciduous. They shade a house in the summer months, then lose their leaves in the fall, permitting winter sunshine to warm the house.
Tall trees should be planted on the south side of a house to provide maximum shading in the summer, the fact sheet advises. Shorter trees do better on the west side of a house, where protection is needed from the lower afternoon sun angles.
Trees take a long time to grow. A 6- to 8-foot deciduous tree planted near a house will shade the windows during the first year and shade the roof in five to 10 years, the fact sheet says. If the tree shades an air conditioner, it can increase the unit's efficiency by 10 percent.
Vines grow faster. Vines grown on trellises also shade a house and cool the passing air. During photosynthesis, water vapor escapes through the leaves of vines and trees, lowering the air temperature by as much as 9 degrees.
Finally, shrubs can also cool a house, by shading the ground and pavement around it. Plant a row of shrubs to shade a sidewalk, the fact sheet suggests, something nice but not too expensive.
you want to open the lower windows on the North side, where it's colder,
and the upper Windows on the South side, where it's hotter.
cool today? not much.
overnight, open all the windows.
as soon as it gets warmer outside than inside, close all the windows, and close the blinds. sun shining in the windows brings in a tremendous amount of energy. if you do this well, you'll be amazed at the difference.
only do the "lower windows on the North" when you've already lost the battle.
My house is well isolated. I open the windows and doors at night and close them in the morning I put a blanket on at night of course. It works almost all summer. Only need air 2 or 3 weeks a year. Talk them in to insulating and replacing window if needed. Tell them it will save fuel in the winter and have a two year pay back. Of course this would not be true if you live in Florida. It is for me because I live in Vermont.
Well, since heat is a form of energy, and it takes energy to move energy, you are out of luck on the totally free aspect. Many of the ideas posted would work ar low cost, though. I espicially like the homemade swamp/evaporative cooler thing, but if you live in humidity it will not do any good. Fans help a lot. You can also run around in shorts and no shirt like I do when I am hot at home. A fan and an open window on the shaded part of the house will work well. Also if it gets cool at night, open the windows and suck all that cool air in the room, then when you wake up in the morning, before it starts to get warm, close the windows and let the fan circulate the air in the room. Also keep the lights and other electrical appliances off, they generate heat. Cover the window, as light is heat, as well.
Good luck. You could just fill the tub with cool water and go sit in it whenever you get too hot, or wear wet clothes and sit in front of a fan!
insulate your walls to re-radiate the heat back out it works well in winter or in summer.
You can buy thermal insulation additives for paint so I suggest having a look at biotech and then painting over your room and roof.
It is the building designers poor part for designing the house like that and there is no way to add insulation to walls now.
Also look into insulation for rooves as your roof would heat up a lot bringing the heat down to you.
Maybe you need to relocate during the hottest parts of the day. Go outside where there is shade and a breeze, like a park with a lake. Go to the swimming pool. Maybe some place with air conditioning, like a mall or library. You could get a job at a business that was air conditioned and offer to pay your parents for your share of the cost for the AC.
the most effective form of air conditioning is designed using convection to take the hot air from the top of the building and bringing cool air from underground by burring a pipe about 1-2 metres down with an inlet at the surface under your gardens shady est coolest tree.
a cooling pond can be put at the base of the pipe coming to the surface this works like an evaporative cooler only your cooling cold air not hot air like traditional evaporated cooling systems.
bringing this cold air into the base of the house will force the hot air out the top and cool your house to twenty degrees even on a forty degree day, this is the only no energy cooling system as effective as air conditioning.
