Hello, Facilities Manager on a Data Center here. Ideal temperatures, are 21 for intake and no more than 34 on the hot aisle. calculate your warehouse temperatures knowing the desired temperature for your hot aisle. Aim for a hot air temperature and calculate your temperatures from there. Also, Kingspan is way better than any other plywood/GIB/fiberglass solution -money wise- for temperature isolation, is fast and cheap to build with if you measure twice and cut once, and you can replace walls with it (not structurally, but aesthetically) For sound, they are a little bouncy, but you can always use what Generators use for baffling: sound proof walls (made of fiberglass foam with a frame) parallel to the walls and parallel to the noise source kind of like ------------------------------------- wall sound source ->> ==== buffers ------------------------------------- wall

The oven-like temperatures Linu$ is running his 'Oven Room' at are basically asking for drive failure LOL Al the temperature recommendations for computer stuff are lies to pretend they are more durable than they really are. The cooler everything is the better. What happens from heat is the boards start dying, like the capacitors & whatever drifting away from their intended ratings & things get scrambled & lost. Also, any drive over 5400 RPM is a $cam, designed 2 fry itself to death. They are not actually faster in throughput because that's more due to aerial density than RPM. Stick to 5400 RPM, & not the CRIMINAL FRAUD fake 'RPM class' lie like WD does, & everything from $eagate is absolute krap, designed 2 die, so your choices R pretty limited =)) Basically, most 'modern' drives R 'auto-suidice junk'. Also the whole 'shingled' thing = seems more like they R using gigantic 'native cluster size' 2 gain space by reducing 'slack' in the 'file system', rather than some kind of literal 'overlapping'. The 'security risk' is similar 2 if U have an 'advanced format' drive with the clusters not aligned, because that 4K or whatever might spread across multiple 'address spaces' on the drive itself, & then U get 'silent corruption' with 'bad shutdowns' or whatever.

Hey, in cases like this, the "quick and dirty, we'll fix it later" approach can make a lot of sense: they are definitely using the version from this video as a mere prototype to work out any kinks and come up with improvements for the professionally-installed version. They already expressed plans to have plumbers later and do this right and discussed some future improvements, and what looked like a single afternoon of work by a handful of guys was enough to prove the concept. On the other hand, imagine going through all the work and expense to get this installed professionally, only to find out that it doesn't work because they overlooked some major detail when designing it and need to hire them back to fix it like they almost did with the filter? What if some safety shutoff was installed in these radiator units that prevented them from being used to expel hotter air than they intake, considering how they were intended to be used? A quick and dirty proof-of-concept prototype can help prevent much worse wastes down the road. That being said, while I see this particular case as justified, Linus is far from off the hook for things that should have been done right the first time. Some of his past data management practices were pretty sketchy for such a technically focused company. Even on this project, while the prototype nature of this iteration is fine in my eyes, they were a bit careless with the water versus electrical panel.

Industrial A/C guy here, Referring to Jake in the beginning A closed loop chilled water system does not lose water over time, or evaporate out. That is why it is a closed loop, they add water and chemicals one time and that's it.Unless the system is drained for repair, or leaks water never needs to be added again. Normally you have a closed chilled water loop, and your Chillers will have an open condenser loop, that cools the Machines, and the heat you brought in from the building. This loop does lose water through evaporation in your cooling towers. The condenser side IS hooked up to city water with a check valve, The water is monitored and topped up with chemicals on a regular basis to prevent corrosion, inhibit bacteria etc. Also side note if LMG actually sees this comment, that is indeed a condensate overflow switch Linus was pointing at in the beginning. Those drain pans are pretty rusty, and may be leaking- which could be a reason these coolers were scrapped. If these are ever used for their intended purpose the pans can be easily repaired by pouring in a kit called PanSeal which self levels, coats and seals the pans. Edit, Im watching this video and cringing again. Between Linus' house and this, you guys are helpless when it comes to plumbing / electrical. Get Jake some plumbing classes, or Hire someone with some Trades knowledge to help with things like this, you spent WAAY to much money on fittings silicone etc. This is such a simple project that could have been done in a few hours. (Just constructive criticism not trying to be rude)

One major issue you'll still have is that the two hoses are not well insulated from each other, in a DC setup you'd run the inlet water on the cold isle and outlet on the hot isle side, because now you're reducing the outlet water temperature and increasing the inlet temperature by running the hoses together. For DC modeling that's nearly a 40% efficiency delta.

Furthermore, a hydronic system likely will run at much lower pressure than city water pressure. A pressure reducing valve will need to be installed as well.

Yup, plumbing engineer and I was thinking the same thing. They're definitely opening themselves up to contaminating the potable water supply. Now, I'm guessing that the building itself was built to code and has an RPZ from the city main, but since they're just tapping into a hose bib, they've exposed the entire building's water supply to whatever chemical residue was left inside those cooling racks. It's unlikely that it's *actually* contaminated things because there's probably not much or any backflow with their setup, but an AHJ might shut the building down because of the "contaminated" water supply. It's one of those things where I feel like LTT is opening itself up to legal trouble by hacking stuff together. They've done enough plumbing on this channel in the past 1-2 years that I feel like they should at least have a consultant.

Fun plumping tip: if your using pvc glue and you're not using the primer the glue will fail to properly set. so not buying the double pack can cost you more in the long run causing you to buy more glue when all you had to do was buy the glue and primer, prime both joining ins, glue one side, and put it together. Anyone who tells you to buy only the glue is just wanting to cause you years of frustration. Since this set up is temporary (just a few months if this video is to be believed) i don't see Jake's bad pumping job going to cause a major failure. in fact you can pull everything apart and fix it right later when you do the more permanent set up. Also I'd rust treat that bottom drip/condensation pan so that part don't fail(use like Rust-Oleum brand Rust-Oleum or rust be gone or something like that).

Unless the pipe is greasy or something there's no need to 'prime' it because the glue melts the plastic together like a weld = they become 'one' piece.

Same with paint = 'primer' is just 'cheap flat paint' 2 save cost on the more expensive 'presentation' layer people will actually see =) What U R getting from 'primer glue' is 'cleaning' & a bit more 'penetration' but U don't need that if U use plenty of glue & the piece is not covered in 'grime' keeping the glue from reaching the plastic. & yes I've done lots of PVC plumbing like sprinklers & home stuff & never leaked on me when gluing no matter how long it sits there.

You need more airflow over the exhause heater rad, to help kick more heat out of the system. Also, you could possibly add a couple of metal radiators... Try throwing some central heating rads around the warehouse to help increase the thermal mass, and dump the heat at more points... Remember your cast iron water cooled system a few years ago? "heating a house with a PC"

Love the content! Please make sure y'all have some way to monitor humidity and pressure inside that server room. Temperature isn't the only thing to be concerned about. Improper humidity control can cause just as much damage as improper temps. Love everything you guys do keep up the great work!

Advice for testing leakage for next project involving plumbing: When you think you are done with the plumbing use an air compressor to fill it with air and spray slightly soapy water on the fittings. If it would leak it will bubble up. This way you can fix leakage without needing to deal with water. Then you can fill the system with water.

The problem as the other poster said is that the air venting out of the servers doesn't have enough pressure to force the air through the radiator on the door to even do anything. The air will just gently hit one side of the radiator and that's it. You need air to go through the radiator fins to make it work. So you end up putting fans on the radiator to force the air. But then you've basically just recreated the point of the giant black rectangle boxes that originally had the radiator but now it's all just way more janky.

@@BichaelStevens I suppose he means that the heat exchange system only works if you have enough airflow caused by either fans on the radiators themselves or a ton of servers literally pushing air into the "hot aisle", creating an area of high pressure on the hot side of the rad and an area of low pressure on the cold side of the rad.

Hold your fitting in your left hand, hold the tail of the teflon tape with your left thumb, roll the tape off the roll backwards so you can tension the tape and roll it off the roll, three wraps around the threads. If you absolutely don't want it to leak, throw some "Gimme the Green Stuff" pipe thread sealant on top of that and you'll never have to worry about leaks.

I went through all this just before retiring. Smart valving and dumping waste heat will work for a good chunk of the year but you'll still need a water chiller for a few months a year to be able to transfer heat when it goes over ~25C ambient. That said, you'll achieve much better sensible cooling efficiency with a chiller than with CRAC units due to the chiller's higher output temperatures (in this case the chiller is interposed between the server room and the external radiators) I did propose that we use the waste heat to warm up the facility swimming pool in winter but that was kyboshed because someone would have to pay for 200 metres of waterline to get to it and nobody would stump up (it would have made the radiator/chiller load a LOT less in summer when the pool can act as a daytime heat soak and night time radiator, with power savings paying for itself pretty quickly) My server room went from being thermally limited to 18KW of cooling to being certified for up to 80kW (with failover) at roughly half the power consumption of the old CRAC setups at full song - most of the time the only load is pumps and fans.... Doing it right is vastrly cheaper than doing it over. It was a £250k job to fit the appropriate power and cooling systems (which I had asked for in the first place) rather than having pointy haired managers discard my requirements as excessive - resulting in the "new server room" being unable to accomodate all the existing kit scattered around the estate as we couldn't cool it sufficiently followed by 10 years of stand-up screaming matches and regulators demanding we clear out kit from the "old server rooms(*), which needed to be repurposed as ITAR secure storage" It's insanely difficult to run a 24*7*365 operation with some contracts subject to downtime service penalties(**) when you're changing the cooling and all the power feeds at the same time (*)those rooms - usually converted closets - ended up being stuffed full of other kit as soon as our backs were turned after we removed the critical stuff, which made the problem even worse. Never allow "temporary" accomodation when closing down an old server room and make sure you disable the cooling, or SOMEONE will manage to sneak stuff in there and make it your problem again (**) When you explicitly say there is no way to guarantee continual service and people sell it to governmental entities with those guarantees, guess whose head that lands on? If you said the IT staff you'd understand why we go grey prematurely.

On our systems we use fully immersive silicone oil baths for the server motherboards (i.e. usually Tyan AMD EPYC mobos) which is an inert non-conductive coolant. The coolant gets sent to heat exchangers / condensers mounted on external parts of our building. We even dip the 20 Terabyte hard drives in the coolant to keep the drives cool. I think we are at 400 ExaBytes for our Vancouver data centre now so that is getting up there in price! LTT might want to look at dialectric coolant in a fully immersive coolant bath scenario for all server mobos and drives.

So the thing is, it's important for the hot "aisle" to not get too hot, because that's also the majority of the surface area of your servers and other gear. All that heat will do its best to heat up the gear that runs cooler, making the fans work harder. You know what else is back there? Your fibre optic modules. In our case, basically the hot air was piling up in the hot aisle, and the fans just couldn't get enough cold air. It was so bad, the hot air was pushing through the gaps between the back of our switches and the rack blanking panels, so they were mostly sucking in hot air. Even where we had custom-made inlet shrouds, the air was still pushing in the tiny gap between the shroud and blanking panels, and also the hole where the power cable came through. First we tried fixing it by removing a few blanking panels here and there to push a little cold air into the hot aisle, but it only helped a few degrees. Eventually we fixed the problem, not by cranking up the compressor power, I think we only increased it by maybe 10-15%, but by increasing the fans from like 10-40% to 50-70%, and now the temps are basically normal. I think the hot aisle averages around 35°C, getting up to around 39°C behind the more full racks. But the biggest difference was the fibre modules. We had a couple of modules that was alarming because they were hitting their max temp rating of only 60°C! I literally burnt my finger touching one of the modules to check how hot it was. After those changes, they went from around 66-67°C to 45-46°C. Thankfully most of our modules were rated at 70°C, so we were only getting alerts for two. So yeah, you definitely want to be pulling that hot air out as fast as you can.

Ditch the AC altogether and put a water to water chiller between the two heat echangers and you'll close to double the heat pumping energy efficiency. Then you can put a heat exchanger on the roof for the summer time(especially as they say we could have an even worse heat dome this year) and just use a 3way valve to direct the hot side water outside the warehouse during summer.

Cause you could miss the intended pun

The valves to choose where to send the heat is a really cool idea. Good thing you've got 6 of the cooling towers!

2 tips. 1. Don't cheap out on thread tape. 2. Don't over pump your loop, you will end up with high pipe velocities and start blowing through fittings, especially 90's.

Server will be happy for additional colling which is primary object of that work or at least it should be for such expensive computer and other colling devices. The idea of having coiling devices in different places with temperature sensors for usage to measure temperature difference and have automatic control valve system for each coller for best performance is great.

You should throw a small 5-10kw geothermal heat pump in that system. The brine side run down to the server room and the heating side up to heat the warehouse. So you can move way more energy without using multiple cooling towers.

I used my mining rigs for heating during the winter while living in the arctic. Worked great.

This series of videos, I love it, I just enjoy this content and it's fun bits

You need an adjustable fluid bypass in your system controling the FLOW RATE through your system. It takes TIME to transfer heat from water to air and from air to water. It is quite easy to push water through a radiator so fast that almost no heat is transfered. Lessons I learned the hard way.

14:36 This whole section was pure comedic gold. Reality, Editing, the whole thing :D

I've seen a datacenter where all fans were taken away from the servers with a closed hot corridor. All hot air was sucked out to the roof so that the cool air (18C) from the front was sucked through the racks. No power costs for 42 HE x 8 coolers x 40 racks of fans... It was very silent.

I had to replace my outdoor water faucet, but not only was it in a really hard to reach area, but the indoor shutoff valve, and the connection to the pipes was seized, and it was way easier to just cut it all out in sections, and start with a new indoor shutoff, otherwise to use a flame torch in between the rafters and all of the many wires and insulation would have required adding a bunch of flame/heat shielding Making the space even smaller. Then I found the shark bites, and had what I knew could take a whole day, done in ~1/2 hour, and its held now for a few years, and the freaking valve is like new, so didn't crust up, oxidize... Great stuff, well worth the money, because it also comes apart just as easy! They even have little sharks engraved on them.🦈

I wanted to do this back in the early 2000's, when hot aisle was the big thing and APC were pushing it. Tho I was wanting to feed the excess heat into a water tank to give the whole building 'free' hot water. I thought it'd be a cracking publicity thing too. Alas, a golf course deal was made for a different idea. :/

Linus/Jake videos are always, always, always my favorite. Just the banter and little tiny snippets of something out of context, the editing. It's a perfect story, with lots of engineering.

If I were you I would change some of those receptacles (outlets) or add more receptacles that are the twist lock type (NEMA L5-20) at 6:51 instead of converting them to a normal NEMA 5-20 plug since you won’t be looking up there at the plugs like ever and since the whole setup is permanent. You don’t want that plug falling out or being loose, especially if it’s pulling a lot of current.

this was very interesting! need more of this!

Actually Jake and Linus, instead of dumping the heat outside when you don't want it, which would be ideal under most circumstances for most folk, you should instead dump the heat into your hot water boiler(s), and possibly even a huge insulated thermal sink to act as a battery of sorts. When you need more heat, you can pull from it, and when you don't need heat for anything, you dump into it. You could do the same thing with the geothermal cooling idea you have with the parking lot, but instead just make a new thermal sink that is insulated for cold temperatures instead of hot. In that ones case, you are constantly pulling its heat via a separate loop dumping any heat it has into once again the heat battery, while having the original loop pass through it to drop it's water temperatures below ambient. Between the two masses being used to modulate the temperatures accordingly, you should end up with an albeit more expensive system, but also more resilient against the swings in climate, room temps due to people being in the area, etc and so forth. The A/C units will barely need to be operated then, ideally; and if they turn on it will be in a worst case scenario where you really want them on. Attach this to some in-floor heating/cooling loops, and perhaps some thermoelectrics where is reasonable, and you could basically turn the entire building into one giant heat pump, with ability to throw the peltier's into reverse for the Seebeck effect. It won't be a lot of power generated, but it might be enough to keep the lights on at least via a backup power system charged by that power generation. In an emergency, this could prove handy, having what would basically be off-grid emergency supply of power if the grid suffers a black out. It won't be much power, but if it keeps the lights on, and some cellular phones active, it's good enough, right?

In row cooling is very neat (cold / heat isles) :) Worked at a place where we used 6 double wide of these units

Where to begin? I guess first thing I'll say is if you guys were located in the US, because I'm an electrical and plumbing contractor by trade who also runs a datacenter in my basement for fun, I would have gladly donated my time to aid in this installation. Second Shark Bites will not leak (as long as the pipe is fully seated within the fitting) and PEX of any diameter, but especially the 1" dia. is a bitch to work with. And finally you could have still used that 1" Schedule 40 PVC pipe as they make 1 1/4" to 1" reducers. That was a very smart move placing shutoff valves to isolate key sections. For such a common sense move you'd be surprised how many people neglect such an important part then when they have a problem the whole system has to be shutdown and drained which leads to headaches later. Also the best tool to cut any type of PVC pipe is just a standard miter saw as it will leave you with a nice clean, straight cut.

WooooW ! Linus Crowd , this video is very astoundingl ! you are just amazing heroes of thermodynamics ! my very congratulations to all team for this amazing process well done! you have to be proud about yourselves!

How about putting two of these cooling units horizontally on the ceiling of the server room? Would take advantage of convection and you could literally double your thermal throughput in the server room, without taking up any floor space.

"Mint!"

Im sure someone mentioned it but 2 words that you should take to heart is "Pipe Dope" I switched to it 22 years ago and I have never used Teflon tape again on ANY fitting from a shower head to Radiant heating and hundreds upon hundreds of fittings and i never have had a leak from first tighten of every fitting, The only thing you MUST always remember is to make sure you leave the end 1.1mm of the start of the fitting so no Pipe Dope gets into the line as it will plug filters, however Teflon tape does the exactly the same thing when it comes apart as I have seen you put it to far over the end of the fitting, I have also seen you wrapping it backwards it wraps with the twist of the fitting to tighten it, However a bottle of Pipe Dope lasts so much longer then a crappy roll of Teflon tape, and works much better. As i'm sure you also noticed make sure when using Pex always remove the white inner collar ont he shark bites as they are just for very flexible tubing such as the clear tubing or something like a garden hose (please don't connect a garden hose to pex lines or Shark Bites except for an end run off drain that has no actual pressure as it will still most likely either pop the fitting out or cause the teeth of the shark bite to cut into the pipe, also to remove pipe from shark bites use an adjustable wrench that you set to the size of the pex pipe. Also in one of the home cooling videos you stated that the gray pex pines allowed air transfer, you got that backwards the gray sheath over the inner black line prevents that, the pex you used in this video actually can if its the older or non thermal pipes allow this effect to happen, the gray and black pex does not and supports radiant heating pressure and temps n problem where the red pex does not. Also the red and blue are designed for color coding your lines aka hot and cold not a type of pipe.) Also while I do love soldering shark bites even on permanent installs are fantastic as you can later if needed alter it so quickly. I was also happy to see you using Shark Bite ball valves but to be able to properly isolate lines you need 2 one for either side of the line with 3 inches of Pex in between which is enough to get your Shake Bite separator or adjustable wrench (Which is way harder to lose then the stupid orange crescent moon shaped separators for the shark bites you can buy, so just use your adjustable wrench and doing plumbing work means you should always have one with you which i saw you using) Also your auto fill solution is i will say inspired. Love it. As for the plastic container, sand it with an orbital sander to make its wall thickness match.

Won't be great as a heat dump after a while though, since they'll want to bury it a bit down. It'll be better as a heat stabilizer, since all that thermal mass will provide a stabilizing effect.

'You know what's not expensive?' lol i thought it would be 'the segue to our sponsor,'

BRILLIANT concept to use waste heat for space heating. Like Tesla! I've always wondered why refrigerators are not placed to exhaust heat to the outside of the room they're in!

I wonder if it would make sense to have the server room AC unit go through a heat exchange block, on the hot return side, than to have said AC unit go to an outside condenser. That water return line still has extra thermal capacity and having two "heating" towers in the warehouse would transfer the heat no problem.
