Hot weather alert! How to cool my house ???




by val.du.12@hotmail.fr » 19/08/11, 15:55

Hello in heatwind time I try to cool my house because the same day with the fly closed there 25 26 in the house. I had bandaged a pipe system containing water immersed in the river with a circulation pump the water would cool in the river and then in the house would circulate in a radiator with a fan and then cool in the river. when do you think ?? Or do you have another inexpensive idea ??? thank you

Hello,

To cool an entire house, there is nothing like the well of Provence: https://www.econologie.com/le-puit-canad ... -1827.html

Otherwise, there was a lot of ideas more or less realizable on this discussion: https://www.econologie.com/forums/fabricatio ... t1958.html

I approve this up. It is currently 29 ° C at home.
It's not with the 24 ° C at night that I can cool down.

New home standard RT2010 so little inertia.

No better at home ... 30 ° C on the mezzanine still at midnight!

I have all my curtains closed and I dare as I can ...

My room is open 24 / 24 is more bearable, like 23-24 ° C when I go to bed ...

In some eastern countries, to withstand high heat they use fans that blow through a grid made of rattan or with some rigid plant stems, on which droplets of water fall.

The passage of air through this wet grid causes localized heat loss.

and voila, 30 ° c to 21h.
It will be difficult to fall under the 25 ° c tomorrow morning with 35 ° c outside

No need to test, it works, provided you force the passage of air through the grid.

In cold greenhouses, extractors are used on one side (large fans) and openings fitted with a "cooling system" on the other. It is exactly this principle, except that the air is sucked through and not blown onto the grid, which is very thick, full of small cells and a film of water circulates through it by gravity.
This grid was cardboard honeycomb strong, the time I was still attending this kind of facilities, I do not know if it is still the case.

Hello val.du.12@hotmail.fr

N times to stop!
that closing the shutter is not enough !!
to protect yourself from the heat of the sun


A shutter in full sun is more than 1m² to more than 70 °
which radiates, in the dark, of the infrared through the glass,
it is "an electric radiator" which works permanently
without thermostat

To block the heat coming from a window or all openings,

it is necessary to deviate the solar radiation by a pastoc mirror sheet
temporarily glue on the shutter.

to which you add a thermal cap a plate of insulation between shutter and window.

The shutter / bracing heats up, but it is not on its own. To put it simply, the air trapped between the window and the bracing provided it is a little "tight" actually heats up a lot (5 to 10 ° more than outside?). Instead of putting mirror plastic with a questionable look and which risks "exciting" the neighborhood, we can ajar the shutters. The air circulates behind and approaches room temperature. The bracing rises significantly less in temperature on the interior side and heats up much less.
