Re: Duct Size vs. Airflow (2012)
#2Ever since buying a house I've been engrossed in this topic along with indoor air-quality and mechanical HVAC systems. There's so much to know about these topics and I feel it helps when dealing with HVAC companies to make sure I'm getting what I want and not be price-gouged. One expert I follow on these topics is Allison Bailes, he has a blog entry on a similar topic of duct design[0]. I find his way of breaking down certain topics simple to follow and enjoy seeing how he's implemented his teachings in his own home.

#3Another good resource: https://homediagnosis.tv
Their youtube channel/resources focus a lot on testing/verification.
If anyone near San Jose / Santa Cruz wants to borrow a blower door and some testing tools for a few days or a week I'll make you a good deal =) -- If you want a non-professional evaluation I'd probably have a day or two of availability in the next few months as well. (I don't have duct testing tools yet, but with notice would probably get them.)

#4I gotta admit, my first thought was "Duct Size" is a weird name for a distributed work-flow tool[1].

Why not get some indoor sensors and DIY? I’m planning to install an ERV and a whole home dehumidifier to see if I can get that ideal indoor air quality.

#8All this assumes airflow to every room all the time.
But in real systems, you only want airflow to rooms with people in. And in a residential setting, you can be fairly sure that won't be all rooms at once.
Which means ducts can be sized differently, as long as you have sensor vents on the end of each.

I can't help but think HVAC is the perfect industry for the limited AI we have right now... it just need to hit a sweet spot of relative humidity and temperature, with constraints given by the assets you have and its' performance envelope given input from mixture of indoor/outdoor air..
but right now HVAC industry is treating relative humidity like some ultimate luxury tier item..
