Alternative to a Canadian well - ambient air of a cellar?

[ThierryL]

Hello,

I would like to cool a living room of + / 54 m2 in summer, i.e. a volume of 135 m3. The living room is very hot due to the large picture windows.

I do not easily have the possibility of creating a Canadian well. By cons I have a very large cellar under the entire surface of the house (117 m2). The cellar is ventilated.

Could I use the naturally cooler air in the cellar to ventilate the living room and cool it in summer?

What is the number of air vents that should be integrated into the living room?


Once the initial volume of fresh air from the cellar has been "pumped" by the living room, will the outside air which will arrive in the cellar via the vents have time to cool off before being pumped again by the living room? ?

Thanks already to those who can refresh my ideas

Hello,

You can start by planting deciduous trees that will provide shade to the sunny facade.

If your cellar is a "real" cellar, its temperature must oscillate between 11 ° and 13 ° C, so use it to cool other rooms, why not, but the disadvantage of your cellar compared to a Canadian well, c is its small exchange surface. On the other hand, since it is large enough, its volume will perhaps be sufficient to achieve your ends ...
I am not a "domestic heat engineer" so I cannot do the calculations ...

If you have land:

Is it possible to bury a sheath (like a ventilation sheath) in order to recover the coolness of the ground?
(that's how a Canadian well works, right?)

Many houses that have forced air oil heating, when the summer comes in a heat wave it turns the ventilation it makes an air circuit with basement and top of the house, the gain is a few degrees, if it works continuously it takes a few hours and the basement heats up. some only operate the ventilation at night or intermittently, it is the cement floor which acts as a cold radiator.
The heat that enters through the windows is enormous, it needs heat-tinted windows, and again, I have a glass roof against the house, in summer with an air conditioner of 5hp I am not able to provide, also in full sun I closes the glazier with patio doors in double thermal glazing. (by cons in autumn is in spring, I do not use heating)
In my case I have a ventilation in the top floor of the house which works continuously it is to pass in an electronic filter with ionizer, this has the advantage of eliminating dust and making a more regular temperature.

What can be very profitable in summer in your case is to place solar tents above the bay windows:

in winter or in mid season: heat and light penetrate easily and are welcome.

in summer: direct sunlight is stopped well before the bay window and the light that comes in is sufficient

depending on the architecture, you have the choice between fixed structures or mobile structures (on reel)

it is important that hot air can escape from the top of the structure

Thanks for all these suggestions.
My approach is also economical in the sense that if I thought of solar fabrics, their cost is relatively high given the width of the glass bays compared to the price of a carrotage in the slab of the ground floor for the passage of a ground duct - cellar and a fan to extract air from the cellar to the living room.

It would still be necessary to know if a drilling of +/- 12 cms wide would be enough to bring about a sufficient air flow only to decrease the temperature of a room by the volume of my living room.

If a sheath is sufficient, given the fairly low cost of drilling and equipment, I would try.

You must seek the advice of a specialist to know the air flow necessary to have a reasonable performance!
If there are minimum air change rates in a room, there are also limits that should not be exceeded.

Do not forget either that it will be necessary to evacuate the hot air accumulating in the room otherwise, the efficiency of your ventilation will be limited.

For the idea that you emitted with the air of your cellar, the principle is good.
Perhaps you could improve it by building a masonry baffle system on your concrete slab. The air would circulate in it and be cooled would be improved.
