Balance of flows on a vmc double stream?

[htd]

Hello.
currently I have a VMC DF I find that the intake of extract air is weaker at the level of the suction than the outlet fresh air is what normal.

thank you for the information

Hello,

When you say "I find" what is it like? Do you measure or is it "visibly"?

a) the perception can be different especially if the T ° of the flows are not the same

b) if there is a difference it is simply that your home is not 100% waterproof ... I assure you, very few are!

It is a classic impression of Bernouilli effect (different speeds on opposite sections), very usual, which gives an impression (feeling of cold on the hands) strong of air flow at the outlet of a fan and not in entry for the same total flow !!

Hello.

it seems logical to me since it depends on the humidity ...

Hello
I do not agree with you (a) and (b)

Hello

can explain more ... engine feels the difference wet and dry ...

Start by answering Christophe's question: How did you measure

[Christophe]

He says he doesn't agree with me but without justifying himself = he seems to know everything ... So let's leave him in his "beliefs" ...

And compared to Michel's remark, it's the same as mine since T ° and% RH are linked ... but as htd knows everything ...

neither, the two are learned ...
