If you have a green thumb I would advise you looked so simple plant transpiration can suffice.
A 20 100 ° C% humidity is 15 g water / kg air
1m3 air is wholesale 1,2 kg / air.
To be comfortable must air between 40 60% and% moisture. If your VMC delivers 300 m3 / h requires a water spray to 2,5 kg of water per hour (air Hr 50%).
I take a random number that can not match the speed of your VMC on flows and I take no account of the humidity outside.
For example 0 ° C air can 3,7 transported gr water / kg air for Hr to 100%.
I do not really know the transpiration rate of the plants I let the hand.

Therefore the surface of the exchanger is equal to the area of the house?
the size of the exchanger depand especially the debit and debit VMC depand not directly from the surface of the house, it depand rather the number of people who occupy the house ... of course in general, a big house c ' for a larger number of people but not necessarily
the surface of the exchanger determines the performance ... too small an area will be a low yield, but will still better than a single VMC without exchanger
so there is not a crack head, any exchanger does better than just VMC, when itself even realized we can foresee the possibility of increasing the number plate, if the results and insufficient increases the number of plate

Ok, thank you for your information, the idea of plants is a classic which I had not thought of!
In terms of the number of person we are two adults and a child, but sometimes it can be three or four adults and three or six children ...
So I guess I would have to foresee a minimum flow for when we're three and a higher power variation for when we are seven ...
After that, if I understand correctly, would be calculated by taking especially into account the volumes of air which must be injected back into the affected parts to determine the fan power to use. Ditto for the extractor ...
Is there a simple rule to determine this? javascript: emoticon (': |')

Hello everybody
Very interesting all these exchanges
I would like to know if it would be possible to simply install a homemade exchanger on the outlet of a hygro vmc to heat the air arriving in so-called dry rooms? Only the motor of the vmc would be used, the fresh air entering the exchanger would be "driven" by depression in the pipes to the rooms as with openings in the windows ...
Sincerely,

Sincerely,
yes, but very difficult as large-area panes very close to each other, necessary (about 10 to 20W / m2 power heat exchange), the very large steam condensation dripping problems and the necessary filters, as real vacuum cleaner Well before VMC double flow !!
Also very very hard !! Otherwise ineffective !!

hello, I wonder if we might not change for a VMC at times (all day because no job) and also at night, where there is that people's breathing and the outside temperature is lower,
if we could not make a partial recycling of exhaust air, filter it and bring down the hall rooms for example. So it would come less cold air, hence economy.
it could vary to 0 50%. Either we put the system manually when starting to work, and one normal calls to return, and then a little lower is called into recycling for the night, at least two hours after taking the last shower, and finish cooking.
Idea to dig.

What is a VMC?
To remove the water vapor in the air and dirt type kitchen (forgetting those in chipboard furniture and Fire-prevention) and therefore must adapt his speed to the minimum necessary, which is excessive in many homes the old standards absurd !!
Certainly, we can cut the VMC if it is not helpful !!
Recycle air is difficult because to remove water vapor, it takes a absorber CaCl2 dry or condenser type fridgeAnd to remove toxic cooking gas (acrolein) or furniture, you have to go on the air own charcoal as for a gas mask !!
If this is done with dust filters it will work !!

HELLO, WARNING, it is not to do this permanently, but just when no one is at home, so no kitchen, no shower, no nothing.
And the night would reduce a little less, because there are still people who breathe. You have to think that the night is where it's coldest.
And it is not stopped. Stop a VMC creates problems include condensation in the pipes because nothing flows.
