ventilation

[xmas]

I have the following problem. Outside temperatures are around -20°C.
So I cannot pull fresh air from outside, because it would be too much work with getting proper temperature and humidity...
If I count that air need to be replaced every 2 minutes...

I would also like to avoid intermediate space, it would do the job... but in small quantities, leading to drop of CO2 level...

So I thought that it's the best option to use

Just to the keep the temperature constant... Which should be easy job considering outside temperature and for negative pressure in room also.

And using some CO2 unit set at 1500ppm will do the job of CO2 problem...


Would that do a job of ventilation, of course with some inside ventilator fans also... ???

thanks for your answers

co2 room can be sealed, exchange air only if rh is too much/low or if heat is too high.

Yup. If you're running co2 you can just go for a sealed or semi-sealed room. Dehumidifier keeps your moisture levels right, co2 keeps your atmosphere ticking along. I get the impression that a lot of this is new for you. For instance I have zero idea what this sentence means:

I would lose co2 at this point unless you really know what you're doing with it. As for makeup air why does it have to be outside air? Is there a compelling reason why this is your only available air source?

I got one of this thing and it makes my fans make weird noise, like make them go "hmmm", if you can say that.
The slower the fans are the more noise they make, its fucking annoying! And I'm afraid its gonna kill my fans!
I have -20C over here, and had to close the intake,like seal the shit up.
I dont use CO2
