Should be titled 100k shipping container lmao! Beautifully done i must say, and given my climate this gave me all kinds of new ideas for the future, thanks for sharing!
I grow in shipping containers as well. We had a really nice heat exchange ventilator that provided tons of fresh air but we had major problems with spores in the exhaust fan/filter.
Hey Brad, why not use black coroplast instead of white? Black is a more radiative color. It may radiate better the layers more efficiently Just a thought, very neat.
Curious if you could record intake and discharge temperature on each end? A little skeptical that it could be 90% effectient , but even if it's only 50-60% still would seem like a worthwhile investment
hey Brad, I just wanted to say that your heat exchanger idea is pure brilliance! Silly question though, being in the Southern part of Virginia my bigger issue is with keeping the fruiting room cooled, even in the winter because of all the heat the bags are generating. I wonder if this same principle would work with a cooling system as opposed to a heating system? Your thoughts?
Using coroplast sheets is an excellent idea! If you do not mind sharing, what type of glue did you use? Also, during the winter have you had an issue with the unit freezing during the high pressure cleanout? Thank you for sharing!!!
I wonder how he will deal with frozen condensation in his coroplast air to air heat exchanger. Maybe it never quite freezes and just falls as water out the bottom?
Short answer: Gravity, velocity, latent heat of crystallization and imperfect efficiency. Long answer: Gravity and air velocity take the warm humid air downward through the flutes, the condensation that forms is in a large enough pore size (3.5x5.5mm) flute so droplets don't fill the channel. The air velocity aided by gravity push the water out the bottom which has a 15" gap to the ground, . In order to freeze, water needs to be "still" and to not only get to zero but to overcome latent heat of crystalization (which is hard to explain succinctly, look it up it's really interesting) also the system isn't 100% efficient so the exiting air of 15C in winter is cooled down below zero but it isn't in there long enough to build up an icicle.
You may have realised by now but that combi boiler is piped totally incorrectly. Assuming your loops are all piped off the "flow" then your returns don't want to be coming back into the same pipe, because as you get further up that run your flow temperatures will drop as you are serving increasing volumes of returned supply to each room, consecutively. You don't want or need an open loop at the boiler like that between flow/return. You need to have a separate capped off return "leg" that takes each return pipe from each room. At the nearest to boiler side of this leg and associated room connections you put in your automatic bypass (between F/R) and your pressure relief valves, so if everything hypothetically went closed circuit the boiler can still circulate around itself.
Capped off probably the wrong way to describe. If you had 6 rooms and 6 returns you'd have 5 reducing tees in your return leg and your last room would connect to the end of your return leg. Return and flow are then only being connected via your safety bypass or via rooms/radiators.
Hey is there a diagram for this thing anywhere, Ive got a stack of these plastic sheet and trying to visualize how he set this up so that every other layer was attached to the intake/exhaust.
Might the fan for the intake duct be on wrong side of the radiator? Is it not more efficient to push cold dense air than pull hotter less dense air. How hard are those lungs aka "flutes in the HRV" to keep clean without an actual immune system? You can see the "every second one is an intake" at time 3:28 ruclips.net/video/hzK9j8oarXw/видео.html (just look for the mold). The warm stagnant water dripping from the warm fogged air ducts during half of the interview...is it leaving a black mold like stain on the floor, and if so, why I wonder?
It would seem likely but Legionella first has to be present in the water it doesn't spontaneously appear. i.e. in the freshwater drip tray that is in the clean air supply or supplied from well water. Further, It needs to be 25C minimum to thrive. My well temp is 6c year round. In summer, on hot days due to the counterflow HRV's natural cooling as well as heating properties, any cooling I've done already has pre cooled the incoming air by 90% so to even hit 25c it has to be 45c outside (unlikely but with climate change....) The ducts pin hole to drain excess water. Many very large mushroom farms humidify in the ducts before rooms and have no known history of this. The larger risk I feel is in a bacterial spore rich room recirculating air past a drip tray that gets re-sprayed into the air vs using a clean supply.
Also Hydrofoggers can be bought with bio cubes to arrest biologicals from developing in the drip tray or periodically you just dump or inject a bit of peroxide into the tray "at night" when you know for sure no one is going to be in there. It cleans the system out of anything that found a nook to hide in. $0.99 for a liter of peroxide which breaks down into oxygen and water so ok for organic use (even as a food ingredient !). You only need a few cap fulls diluted into a gallon to kill bacteria. Some people even drink that concentration but still best to avoid the aerosol version after addition. Fogged peroxide doesn't harm mushies at that low concentration either but bacteria can't stand it.
@@whatthefungus Is Brad a contagious disease specialist as well as an HVAC design expert? While legionella is just a single example of a very long list of bacteria that thrive is such a system like the one he has created, there are many important points you may wish to consider in this review of peer reviewed articles linked below. Of special note, is that the test your doctor will use to try and diagnose your "flu-like symptoms" is specific to only one type of the over 30 species (and counting) of this zoonotic. 1/30 ain't great odds in my books.

Not really, guessing you havne't grown oyster mushrooms in a crowded grow room then . :-) 10 FAE is common in commercial growing environments that have high density. every 6 minutes = 10 FAE.
@@HeyZeus667 My apologies, I didn't mean to insult but can see how it comes across that way. Not everyone jam packs their grow rooms so many growers get away with 4 or 6FAE then find problems when they scale and fill it up. That's because co2 and the long stem "bats" that are induced are proportionate to the density of a grow room or quantity of total "exhaling" mushrooms per square foot. Often square footage is the only basis to calculate FAE but It should really be based on density. I just meant to say 10 is common for oyster growers.
@@HeyZeus667 He threw in the smiley face... I seriously doubt he would have gone through all the work to build this exchanger if the solution was just exchange air less often.
wow! this guy truly is a genius. Thanks 'Brian for showing us all that!
Ya it's fun showing Brad's full potential on my channel.. I hope some people get inspired by him
Brilliant! I love the ingenuity. The mushroom community has some of the best minds ever
What a real piece of work he’s got going here. Awesome to see. Thanks for sharing!
This guys is an incredibly smart engineer. So fucking cool. This type of stuff gets me so hyped haha.
Overkill.
Way to elaborate.
Gonna spend lots of time maintaining it.
Love your energy and ingenuity.
Brad is always innovating

Lol this guy is @ creator level.
The thoughtwork.. love it!
This guy he's too smart I can understand what he saying actually you can explain it which makes a person twice as smart
ya exactly... lol. Brad has been a huge help to me over the years and I really wanted to make a few videos that would help him
I grow in shipping containers as well. We had a really nice heat exchange ventilator that provided tons of fresh air but we had major problems with spores in the exhaust fan/filter.
whoa ! amazing
how do you connect the intake air even layers of coroplast to the box inside ?
Hey Brad, why not use black coroplast instead of white?
Black is a more radiative color.
It may radiate better the layers more efficiently
Just a thought, very neat.
Respect. Very intelligent. Inspirational
Thanks guys!

Did you ever get this answered? I would like to know this as well.
I imagine if you hook it up to a large brew chiller it could work
Do you use full size containers? Also build out the regular or have you used refrigerator units?
Using coroplast sheets is an excellent idea! If you do not mind sharing, what type of glue did you use? Also, during the winter have you had an issue with the unit freezing during the high pressure cleanout? Thank you for sharing!!!
Contact Brad for HRV plans
Great ideas.
You made a plate and frame heat exchanger with corregated signage.... fuckin brilliant
nice to see elon musk's eloquent brother growing some mushrooms
I wonder how he will deal with frozen condensation in his coroplast air to air heat exchanger. Maybe it never quite freezes and just falls as water out the bottom?
doesn't appear to be an issue. It was -10C the night of my visit.

Nice! But how does he keep the right temperature at summer?
The radiators will cool the air in the summer

Does anyone make a kit where I could grow 2 lbs of mushrooms a week inside an apartment for my family?
Neil oppa yes lots of people! they sell pre colonized fruiting blocks is say get about 10 and stagger thier flushes
NICE!!

Same, how does the manifold discriminate to its appropriate channels

Pretty sure that is just dirt. Brad has been using this HRV for 3 years. Maybe he will respond soon but I don't think its mold
Said it before genius lol
fogger in duct = legionnaire's disease, etc, death trap
that is a good point actually.. maybe Brad can comment on this

Not sure why he needs to exchange air every 6 minutes, that seems excessive.
