VMC: invent system from germany

[Ahmed]

Interesting ... It is also the principle of the regenerators of Stirling engines.

Rather interesting ... But for the price, there are certainly no conduits, but there are several motors ... It multiplies the mechanical parts and the motors. I don't know how much it costs to install in a house with lots of rooms ...

I take a detailed look ...

Do you know what that means?

Uh, not too much ...

Except that Thumbnails = reduced images ... so try to delete the preview (left column)

I would install the latest version, unless otherwise impossible. Acrobat Reader is free.

No news on this system ????

I found a reseller in France, go to the site
www.construire-sain.com who will offer the doc of this product soon

I saw a hybrid system between this one and a classic VMC DF.

Me too, I had then found the brilliant idea ...

However, I point out to you that the extracted (polluted) air then circulates in the same conduits as the blown (healthy) air. This results in possible contamination of the air blown by the extracted air ...

The delta temperatures are likely to cause condensation phenomena which are deposited on the exchanger (dust, pollutants, odors ...). These pollutants are therefore likely to be reinjected when the ventilation cycle is reversed ...

Exactly I made the same remark.
And given the low development of this product in France, I could not see one in operation to get an idea of ​​the noise (apparently they say there is very little noise, but I wanted to make sure. ..).
On paper anyway, the idea is great, and could be applied much more easily than a classic VMC2F with all the sheathing to go; their announced returns also seem very correct ("up to" 92%).
In terms of air quality, that can be a real problem. For dust and pollen, there is a filter, and the humidity seems to be controlled. But I guess the filter does not stop everything ... I am in contact with someone who may be distributing it in France, but they are waiting for the same information as us. I will keep you informed if I manage to obtain test results or technical tests, even if for the moment it is likely to be mainly manufacturer data.

A presentation that shows that 8 000 installations were made in 2008:

And with a "double flow" CMV you really think it's better?

Personally I do not think ... CMVs are shitty nests after a few years: very difficult to avoid bacterial development except to clean the entire sheaths regularly.

Fact: allergies have exploded since the requirement for CMVs everywhere ... a coincidence? Maybe not...
