Mexico naturally faces water scarcity and inequality. Approximately 70% of the country’s territory is close to day zero in terms of water availability. Despite a 15-year drought and low water levels in the Rio Grande, the City of Las Cruces, New Mexico, has a secure water future, being carefully planned and managed since 1930. Las Cruces Utilities draws water entirely from approximately 72 wells located around the city, tapping into depths of up to 1,290 feet in the Mesilla and Jornada bolsons. They do not rely on surface water from the Rio Grande. The Nestlé bottling plant in Veracruz, Mexico, made significant investments in environmental technologies. It uses wastewater treatment systems to ensure 100% water recirculation, zero wastewater discharges, and zero waste to landfills. Additionally, the factory consumes 100% green electricity and utilizes a biomass boiler that generates energy from biological waste produced during the coffee process.

HVAC engineer here. If they would just choose to build these data centers in a cold enough climate, Alaska for example, they could cool the whole facility entirely with outdoor air practically year round. For certain climate regions, the IECC(International Energy Conservation Code) currently requires most HVAC systems to use an economizer. When outside air is sufficiently cool and dry, an enthalpy economizer works by mixing outdoor air with return air to achieve the desired supply air temperature, 55 degrees Fahrenheit. The only energy required is what is needed to power the fan motor. These systems save massive amounts of energy in colder months. Office, industrial, and large buildings require cooling year round and only need heat at the perimeter of the building and during morning start up. I don't know why they choose to build these global data centers in hot deserts. By the way, an error in this video. Outdoor air is generally cleaner than indoor air. That is why it is mandatory to have outdoor air brought in for ventilation for buildings that don't have operable windows. A ventilation schedule is one of the most basic things a code official will require on mechanical drawings. Outdoor air ventilation is so important, it often governs the sizing of equipment. A conference room for example requires 5 CFM per person of outdoor air with an assumed 1 person for every 20 square feet and 0.06 CFM per square foot of outdoor air. That works out to 0.31CFM per square foot. That means a 500 square foot conference room requires 155 CFM of outdoor air. The catch is, a typical HVAC unit can only cool a certain percentage of outdoor air vs return air in hot summer months. A safe rule of thumb is 20% for my climate zone. New units can some times do more than 25% and dedicated outdoor air units can do 100%. That means a 500 square foot conference room would need 775 CFM total and would require two tons or 24,000 BTU of cooling. That is far more cooling than the room will need to satisfy temperature.

I mean, this water problem is really a thermal dissipation problem as far as I can see - and since large-scale computing is limited in density by thermal dissipation, it just means that the "problem" is a foregone conclusion. Optimizing anything to improve thermal dissipation will just result in denser datacenters that pack more computing power, consume more energy, and run into the same thermal limits. They will never stop having this "problem" until a different bottleneck is hit or until water stops being the cheapest/densest thermal management option. At the end of the day, it all boils down to the same old engineering problems - reducing power consumption, using renewable generation, more efficient computation, etc. And again, it will lead to more powerful datacenters, not less thirsty datacenters.

Water is used for condensing cooling because it's cheaper than air cooled radiators, or massive ground loops of pipes which would have almost no water use. I think the real problem when talking water policy with people is that numbers of billions of gallons sound large but don't mean much. Farmer used acre feet of water (the amount of water needed to cover 1 acre in 1 foot of water), which converts 1 acre foot to 1233 cubic meters of water or 325,850 gallons. In context the Mackenzie River in Northern Canada dumps an average flow of 10,000 cubic meters a second into the arctic ocean. Google's 4.3 billion gallons of water converts into 1,627 seconds of the average flow of the Mackenzie River, or about 27min. All of Google's data water need is met by half an hour of flow of a river that is almost unused for human activity. The total economic activity of the Big Mac might be expressed in millions of dollars not tens of millions. The water issue and the fear of misusing water is a peak first world problem. We can solve it by accepting a return of slightly warmer water back into a municipal system negating all the issues, are you going to care that your cold tap water was 2 degrees warmer than it was before the data center used it for cooling? We could also force data centers to used closed loop air cooling, in practice the same as your computers air cooling only with huge fans blowing massive amounts of air. We could have buried water loops dumping heat into the Earth. Or just bite the bullet build lots of cheap nuclear power and run energy intensive refrigeration systems. Cooling towers are the cheapest solution so long as water is legal to use. In terms of water use they are fantastically efficient and almost benign to the environment. That's why we use condensing steam turbines in power generation. Cooling the steam to a condensation point pulls a vacuum on the turbine which provides more monetary value of electrical energy than it costs to reheat the steam back up to it's operating temperature or to pay for the water use.

I know it is a minor detail, but the water that is being cooled in the cooling towers does not produce steam.

@xjdisuehdАй бұрын
One test which I was a part of as a chemical engineer was simply rejecting waste heat to the atmosphere without the aid of cooling towers. There are to be two cooling loops in the data center. One is internal cooling loop, while the other which transfers heat from the internal loop to the external evaporating-condensing cooling loop. On the external loop, different refrigerants were used, in some cases the refrigerants were special mixtures or developed specifically for this task. When passed through compressors arranged in a series format, rather than a parallel format, each compressor in a series steadily increasing temperatures and about 3rd or 4th compressor is where phase change starts occurring, from gas to liquid. We were able to achieve temps as high as ~250C at the end of compressor series. Now, since the delta between ambient temperature and the liquidifed refirgerant was so great, absolutely amazing rates of heat transfer were achievable and by the time the liquid refrigerant cooled down to about 100C, we would send it to the evaporating loop, to pull heat from the internal loop. 1. The cooling fins of the condensing part of external loop are exposed, requiring frequent cleaning and maintenance. This can probably be automated for large scale operations. 2. Refrigerant decay occurs due to wide swings in temperature after a few thousands of passes through the evaporating-condensing loop. This needs better research and development work on different types of refrigerants. 3. The external loop needs to be much more sturdier and this causes thickness of tubing to increase on condensing side, to be able to handle the absolutely crazy high pressures for HVAC. More fins, and better materials, namely copper preferred. With current copper prices, not so cheap. 4. This absolutely requires higher electricity demand than a process which involves evaporating off some water to get rid of the heat. One proposed solution was to have mega-clusters of data-centers with local battery backups. For eg. Google, FB, Microsoft make data-centers in Wyoming, and power them with the wind energy there. And have a gigantic battery backup so operations run 24x7, and the wind turbine and battery backup is managed by a company that Google, FB and Microsoft create together. This has the disadvantage of bringing in talent too close to competition and one unnamed company outright refused to even consider this. 5. This is difficult work, as there are no known standards anywhere for this design, so whoever does this first will probably writing the standards or have great influence on those. 6. Unless multiple companies come together or anyone is willing to give this 100% commitment, establishing the research and legwork, this is too expensive for anyone company to spend that much in R&D and capex.

In Minnesota, we get free cooling for data centers when the ambient outside temp is below about 32 degrees. It works using an external machine called a "dry cooler" which is basically a large fan cooled radiator that cools the external water loop. It gets rid of enough heat to require no evaporative cooling during colder months, so evaporative cooling works in the summer and free cooling in the winter.
@siberx4Ай бұрын
This only happens because we have, historically and currently, dramatically underpriced water. When your water is nearly free, it makes sense to reduce your power bill (which costs you actual money) by consuming some water for evaporative cooling (which is close to free). Same thing with power plants; they use evaporative cooling because the water costs them a tiny fraction of what it's worth. It's entirely possible to have an electric grid that consumes no water whatsoever; renewables do this naturally, and even thermal power plants can be cooled in other ways (at the cost of consuming some of the produced electricity to drive the cooling). Data centers could entirely operate from air conditioning (to air or ground) or, even more efficiently as you note, with free-cooling (potentially coupled to watercooling inside the facility). As you pointed out, hard drives are one of the more temperature-sensitive components, and they'll still tolerate 45C or so just fine; well above ambient temperatures in most locations. There's no reason you even need to use air conditioning if you can transfer the heat from your components (which only need to be kept somewhere between 40c and 90c) directly to the surrounding air and get rid of the heat passively.

Screw compressors are actually more efficient on their own than the centrifugal compressors which are more common on water cooled chillers, but of course that's lost when there are so many motors running for a bank of air cooled units as opposed to only a few water cooled ones, and because DX compression is more energy intensive than simply pumping water around for evaporative cooling. Other savings on makeup water costs, a big advantage with large numbers of air cooled units is the sheer redundancy of having dozens of machines that can easily bare the extra load should something fail.

There’s a startup here in the UK called Deep Green that has a more unique means of recycling that heat: heating swimming pools. Given how much more expensive it’s become in recent years for local councils to heat public swimming pools, it cuts their heating costs while also allowing for a great way to cool data centres installed beneath them!

I paid patreon to see this video. Thermodynamics! When it comes to harddrives, the benefit isn't about the ultimate temperatures, but temperature fluctuations. Keeping HDDs at a steady temperature increases life. After all, they are precision machines. It's also worth noting that water consumption is modified by the cost savings, i.e. they don't want to build cooling towers to recycle water.

Back in the day, our hospital moved to a new data center, and when we were 100% operational, we lost a chiller followed by the backup (a rag stuck somewhere?? and evidently failover wasn’t tested? Anyway…). It got really hot, and really humid, really quick. It was at the end of the day, so fortunately a lot of us sysadminsmwere still there, shutting down hundreds of vms, the hardware, disk storage…etc, all in an effort to keep our AIX Epic EMR servers/storage up. The AIX was a giant p690 and the storage was a full rack of spinning disk - with two of them for redundancy (in the same freakin’ room!! We lost that battle, but got them geographically dispersed later.). When the air temp hit 120deg, I was cleared to shut them down but then the chiller came back online. The point: we were losing disk all over the place, often at the start but gradually back to normal after over a year. Oh, yeah, this happened in Wisconsin in the late fall. Not like we had windows to prop up some box fans, but still ironic a bit.

Your mention of Arizona brought to mind TSMC's construction of two fabs in that state. TSMC will use water extracted from the already depleted Aquafier as part of its production process. The seven stages of washing the silicon wafers use considerable groundwater. Some of these stages need to use toxic chemicals. As part of their agreement with the state government, this water will be processed through a desalination plant and returned to the aquifer. How well the process is monitored for toxic chemicals returned to the aquifer depends on the vigilance of the state government. American environmental protection is not at the top of the list for excellence worldwide. It will be interesting to see how well they are policed when the new TSMC fads become operational. Thanks for another excellent presentation.

Watching the video though, lots of small details are a bit off. They dont change the overall message, but worth mentioning regardless. It seems you're well versed in energy therory, but not the HVAC industry. - CRAC is normally pronounced "crack" - In the evaporative loop, there is normally a water cooled chiller in between the two loops. - the system you described with two loops primarily cooled by water is a water side economizer. They are some of the most efficient systems in many climate and weather conditions. - direct cooling with the outside air should never come at the expense of dehumidification, the AC part of the HVAC cools and dehumidifies. Often air-side economizers are programmed with enthalpy controls to prevent this issue. - all of the systems described here are a part of the HVAC systems

Cornell University has operated a deep lake cooling system since the year 2000. Cornell is close to Cayuga Lake, one of the Finger Lakes. These lakes are pretty deep - down near the bottom, the water temperature is consistently low. The system draws from the bottom, heat exchanges it with a closed loop which then sends chilled water up the hill to Cornell. The entire of Cornell's campus is cooled this way, as is part of the local school district. Cornell has a website that has a lot of details including annual greenhouse gas savings. Prior to the deep lake cooling system, Cornell chilled its water using a plant that was powered by... coal. There's another system using Lake Ontario water in Toronto. Anywhere you're close to deep water you'll find it nice and cool at the bottom because cold water sinks. I believe there was a demo system in Hawaii using ocean water. The potential of the oceans for this kind of thing is massive, but salt water is an issue and if you're not in a place that's already cold, you need to be near deep water. The potential of the Great Lakes for this kind of thing is enormous too. You'd think Iceland would be a natural place to site data centers. Inherently cold, near a lot of cold ocean water, tons of hydropower energy, etc.

No need for evaporative cooling as the fluid was coming out towards 40'C and the chips themselves - as you say - could run even hotter (60'C was a reasonable target).

There is a misconception I keep hearing and I want to know where this notion comes from, or it's a misconception as far as my understanding and that's this issue of power consumption inside electronics being turned into heat, as if this means if 100KW is being used at any given moment, it's THAT amount of power generating heat but for the LIFE of me I don't understand the physics of THAT one, so someone PLEASE enlighten me. My understanding of electric power is that it's a form of energy. Energy can be converted to do different things. For instance, in a simple home PC with a modern CPU and say that CPU has 10 billion transistors in it. What you are saying is that all power is converted to heat. What the hell was switching those transistors on and off? You can run electronics to where a unit is putting off almost no heat simply because you run it at low frequencies. The unit is still doing WORK, switching transistors on and off along with making other components work. Slow down a CPU to 1.5 GHz max and tell me if you need that big honking cooler on it. As far as I know, switching transistors on and off is REAL WORK. Computing is REAL WORK. Heat is generated, yes, but I can run a brand new Intel or AMD CPU and have it generate almost no heat and the efficiency of the circuit will be CRAZY GOOD, because I slowed it down. Heat is generated as a result of reactance in electronic circuits that have clock signals driving them, where a clock signal is very much an AC signal (I've put an O'scope to plenty clock signals). You also get SOME heat loss as a result of switching transistors on and off but for the LIFE of me once again I don't understand how that's 100% of the input power or you NEVER would have switched the transistors on or off, which is REAL WORK. So, there is SOME heat loss from switching transistors on and off. 500W being consumed is NOT 500W getting turned into heat. Get a small electric heater and run it around 500W and let me know if that's what your PC feels like and if it is I REALLY feel sorry for you. There is MORE heat loss from reactance in electronic circuits driven by high speed clock signals, WHEN you push that clock signal up to the point where the die starts on that exponential curve of inefficiency. Every process node has different characteristics, one is power efficiency at different clock speeds and that's an exponential curve, so the faster you clock the die, the faster the rate of change in inefficiency of the die. It's not linear, it's exponential. There is a point where pushing the clock signal faster isn't worth it because the power consumption is not worth the small gains in REAL WORK, the actual computing being accomplished.

It appears that power efficiency is unfortunately not really a design goal for many of these servers. They seem to lack many sensors, which leads them to run the fans at a much higher speed than they need to. The amount of energy saved could be very significant with better firmware design. I'm also very surprised that nobody has come up with the idea of centralized fans (i.e. one large fan to cool multiple servers). This would allow them to run silently and in a much more power efficient way I think.

Many thx for the video. I feel it's a simplistic view and oversimplification of the issues. Conventional approach to DC cooling evolved has many years with convenience in design where chassis cooling is a simple exhaust fan system, leaving the DC HVAC system to handle the 2nd stage externally, often times many unknown variables and designed with universal setup in mind. So a DC design has few specifics on varying chassis cooling needs, often falling back on some universal specs. Usually trying to keep entire area inside DC cooled per specs; usually about 16c~18c and humidity within 40%~60%. The inefficiency is that the DC cooling system circulate expelled air from racks back to HVAC unit directly, temperatures breaching (high 80c or so?). So the HVAC load is something like a delta-T design of 65c; plenty HVAC capacity required. This given ambient temperatures are usually a good 40c lower, why not simply expell exhaust air, introduce filtered fresh ambient air for some 50% off the HVAC load? Some engineering work to redesign the flows can easily yield tremendous savings. Perhaps the time has come to redesign chassis to have universal liquid cooling fluids system that work with in-rack heat exchangers which in turn run an external liquid cooled loop. Such a design approach will leave the larger DC area needing a lower cooling load. Cooling designs for chassis and rack designs need to become integrated with DC HVAC designs; definitely workable solution that will reduce the HVAC load. Given ESG is the rage, some incorporation of heat harvesters, Peltier Thermoelectric, Coldplate/Heatpipes or even PCM tech can put that expelled heat to some use. Idea concepts are out there, just need to integrate the various entities: www.supermicro.com/en/solutions/liquid-cooling

Many electrical power plants in downtown Detroit that used to burn coal and have since been converted to natural gas make extra income by selling their waste low pressure steam from their generator turbines to the local downtown business district office towers for heating in the Wintertime. If you drive around downtown Detroit you see what the locals call Hell's Steam vents releasing steam (I assume from leaky pipes) up through manhole covers to the local avenues. The City had its own power generating lighting plants that have since been sold-off to DTE (the local power utility). These same generating plants supply electrical power year-round to the downtown business district. The expended steam is then returned to the same generating plants as condensate to be reheated back into super heated steam for powering the turbines. In the Summer they supply chilled water from evaporator water air cooled units for downtown air conditioning. This shared system has been in place in Detroit since the 1920's. I used to service DTE's data center and they used to brag about how cheap their steam heating bills were in the Wintertime. Steam heat is also used to thaw out side walks, stair ways to office buildings and some streets in Michigan. If data centers located further North in Michigan they might find more customers for their waste heat and save water by recycling it back from heating customers. Many large Michigan cities already have the under street steam tunnel infrastructures in place. We also have a lot of fresh water around the Great Lakes area for cooling. The only condition is if they draw water out they need to filter it before they return it as run-off water to maintain the lake and river levels. Water drawn from the Great Lakes runs cool around 50 degrees all year long and especially when the lakes freeze over. The only issue we have is a lack of new electrical generating sources. Smaller scale nuclear plants that can be licensed more quickly might help to solve that issue. Many power plants in Michigan are called co-generation plants as they supply both electricity and local steam heat to their industrial customers. There is also a lot of unlit fiber installed in Michigan for transmitting data. Moving North makes more sense to me than locating in hot water scarce states like Arizona.

It's important to remember that water is not consumed in the same way that fossil fuels are. Water is simply relocated from its natural source and released back into the environment.

apologies but this is at best an oversimplification - water sources rely on _replenishment_ and the actual replenishment processes for some sources can be measured in decades or centuries, or in some cases not at _all_. this is particularly true of groundwater sources which involve very slow processes and usually ENORMOUS (subcontinental, I do mean enormous) reservoir sizes meaning that the supply is for practical purposes, finite. loss to these sources in america is well documented. usage has increased SEVENTEEN times since 1940. 40% of tracked wells have posted record depletion levels in the last decade, and that in turn is reflecting in the exceptionally poor performance of cropland that largely overlaps almost perfectly with the most depleted and water-scarce areas. hell, I'm not even touching on rivers, lakes, reservoirs. freshwater usage, depletion and general management is a serious problem. 3%. Three percent.

A LFTR (Thorium fluoride molten salt breeder reactor would run a large cluster of data centers for about 30,000 years between refueling. Since there are already tons of thorium piled up everywhere that "rare earths" are mined You can't transport it. Burn spent fuel rods from U-238 water cooled reactors + thorium already mined makes a cheap 900° C heat source. A LFTR reactor the size of a suit case could easily handle two data centers. Running a dehumidifier outside will collect more water than they lose.

13:55 that graph is interesting, because I've been confused when I first heard that HDDs can die as fast as within /one/ year, yet I only had 2 drives in my entire live that were that bad. The majority lasted 5 and weren't replaced due to mechanical age, but just because they were so old that their capacity was abyssmal at that point. Now I wonder if part of their long live might have been from the fact, that their average temp was near the end of the graph, where the failure rate went down.

I think a case could be made for establishing acres of greenhouses around such data-centers, where the heat could be used to grow various vegetables and fruits for nearby markets. This would obviate the need to air-freight at least some of such produce from distant countries, thereby helping to cut CO2 emissions, create jobs and maybe reducing prices of those products.

Why not build data centres 10 metres below ground level? It's cooler down there and the temperature is more even all year around, so less management of peaks and troughs.
@celeron55Ай бұрын
The ground, depending on the type of course, actually doesn't accept a constant stream of heat well at all. You can put a certain (large) amount of heat into the ground, but that makes it hot like a heat retaining fireplace, and after that you can't put more heat there, instead you'll have to either wait for a long time (possibly months) for it to disperse, or suck the heat back out from there. It's a form of a thermal battery, actually - not a cooling solution.

8:52 they're trying to restore their water sources, but the question is how are they doing it? They can take it from a water source that creates a new water problem in that area.

If your in a desert... Its really cold at night. Why not store the cold at night in water storages tanks to be used during the day... Thats sort of what some highrise buildings use . They use their AC system to cool the coolant in storage tanks when electricity is cheaper at night and use that stored cooled liquid to cool the building during the day...

Telia's Helsinki HDC dumps the heat to district heating, so reusing the heat that way. It wasn't still online couple of years ago when i visited because the datacenter didn't produce enough heat at that point as migrations to the new datacenter were still on-going, but i think it's online these days.

They could build them next to hydro electric dams and use the high head pressure to feed the external loop and dump the hot water back into the reservoir.

I liked the comment about 100% of data center energy is converted to heat. So it struck me that like the old saying about 'The statue was already there, I just removed the extra marble.' i think you could say 'The data was already there, I just removed the extra heat (in a very precise way).'

there is one use of water you didnt mention. To have the air carry enough heat efficiently they need to keep certain air humidity values, which requires them to spray water in the ventilation system.

To be honest, software companies shouldn't bother having anything in the Southwest, if cooling is the issue. They should stick to building data centers only in the north, coast to coast.

Hopefully the ongoing deployment of off shore wind here in southern New England will drop wholesale electricity prices low enough to entice large data centers. We have small rivers aplenty that used to run mills, they will cool a data center fine too, in fact the elevation drops for the old millponds can power coolant pumping needs too.

@noneofyourbusines2000 There is no "global data center" Data centers are spread out all over the world. For example Netflix has roughly 243 locations for it's data centers. Physical proximity matters in networking. The longer the distance, the slower the speed and larger the latency.
