Loved it. I'm part of the DDC division of an HVAC company, and I want to thank you for all the informative videos that keep me learning, but also helped me get the job. Currently I am working on a 1,000,000 sq ft data center project that is truly a feat of engineering. Love my job. Thanks, again.
Eric
Hi Eric, I am looking for job in data center as ME engineer. Could you please guide me which skills should I focus on ? Currently, I am learning REVIT and have done analysis in CFD.
@@javalearner4227 Hi I'm a Dceo operations engineer and did Mechanical engineering. You need to have good knowledge in HVAC, Fire fighting and electrical systems.
very excellent video, I learn new things by watching
I work at JLL in facilities management your videos are really helpful.
I do this everyday this video is spot on great job you deserve my thumbs up
I've never subscribed to a channel so quickly, finally I've found some quality MechE content on YT.
Could you also do a series on semiconductor cleanroom engineering?
In 2004 I worked in a sign shop that had been built to be a data center but which never took occupancy when the Dotcom bubble burst. The only climate control they had installed was a massive AC unit like these CRAC units, but which didn't have a controller. It was either on or off. In 20-30 minutes it dropped the temperature from about 85°F to 50-55°F. And while it was running it was deafening. But we only had to run it twice a day during the hottest part of the year.
Awesome video and very well put together. I currently work in constructing data centers and this video is perfect for anyone who wants to learn how this building gets cooled. I hope to see more videos coming from you explaining the electrical side such as how the power gets distributed from transformers to generators to Ups,PDU’s etc.
This video is particularly applicable to me.
Modern HPC clusters often have power consumption in the MW range and often uses liquid cooling for CPUs GPUs and RAM, these usually consist of a local liquid loop with a heat exchanger linked to a secondary loop fed from the building chilled water system.
This is helpful for my architectural thesis, thanks.
I work on this stuff near daily, but I just started a month ago. This is very helpful!
What type of back ground do you need to pass ? Squeaky clean or your allowed a misdemeanor like a DUi
I just had a company reach out about a job opportunity for Data center hvac. Worth it??
This is an awesome video. Thank you so much for putting this together. It is very helpful.
One work exceptional - thank you
Side note, if the CRAC unit is using chilled water then it's typically called a CRAH (computer room air handling) unit. This is due to not having the compressor or majority of the work to cool being actually IN the unit like it is with a CRAC unit. With CRAH's the compressor doing the most work is typically in the upstream chiller or heat rejection equipment of similar type and function.
This is a cool video, but I work for a big commercial refrigeration and HVAC company in Arizona. I have never seen this. We do all the work for Century link in Arizona. They only use chillers or rtus. I’m not saying this doesn’t happen, but I think with all the bad airflow just use a chiller with multiple air handlers. Thanks for the video.
Your content is so touching
Great work done well
Thank you Paul!
Probably the coolest video on data center environmental design
well played pun
The Engineering Mindset - I work in a small tech center and we don’t use under the floor forced air cooling because it requires plenum rated wire that is much higher $$
So we have to have the supply and returns in the drop ceiling- cold supplies in front of the racks and returns behind. Not nearly as efficient as supply below the floors. And some of the equipment pulls from the rear.
Sounds like some CFD sims could help you prove the business case to invest in improved cooling!
Would be good to see a video on static transfer switches 👍🏻
I found it realy helpful.
Great information. Thank you
Wow, great work!!
good explanation..
You have good application of Air conditioning systemapplied to all type of Area of location in a residential or commercial building.
Nicely explained-
Awesome!
I just knew the hot isle containment.. 👍👍
Thanks for the video =)
Can you explain about relative humidity. Why it is important in precision AC and data center
PLEASE TALK ABOUT HVAC SYSTEMS ON NAVY SHIPS
If he knows about that he will do it.
Thank you sir.
1. Are data center can work on partial load like residential unit? Are there any load variations on a server room?
2. In free cooling method without plate heat exchanger, is there any limitation for moisture for electronic devices?
Sir, you are explaining in much easier way but can you please explain what is basic of data center after that this critical one
I'd like to know how fire suppression nozzle will be placed if there will be a ductwork for hot aisle containtment system?
This is also called CRAC (Computer Room Airconditioning) units.
Very good video
What standard is used for hydrotesting of chilled water pipes?
Please make video on immersion cooling data center technology.
Nice video
Thanks
Thank you!
Do you know what are the average outlet water temperatures from the chillers for these applications? Would water need go below 0°C?
May you share the Simscale design? :D
Good explanation Paul,
Can you make more videos on Data center or can suggest CZcams channel which offers good learning for HVAC design in Data center w.r.t uptime or TIA tier certification
Thank you. I've been planing to do a video on CRAC units for a while, maybe evaporative coolers too. I think next month we'll publish a video about some colling components inside a CRAC unit so we can tie that in to data centres
With regards to the DC Energy Consumption ratio: I think its best to allocate 50% of power on HVAC and 36% on IT Equipment (10% on Network Devices and 26% on Server and Storage).
I think if that's the case, the PUE will decrease
Can you please help us to understand the effect of unfiltered or generated gases due to heat..what are the effects and how can we tackle the issue..
I find it funny that HVAC is for Aircons, where its been a very long Time the means of "High Voltage Alternating Current".
👍👍👍
what the best hvac system design for data center
What are the sources for this video so I can do more research?
Hey, im currently working on my assignment data center. Does anyone know how to select diffuser for floor raised.
Great video! I don't know if I am the first to nerd out on this video and pick it apart like a troll, but you incorrectly call a computer room cooling unit (@10m:44s) connected to chilled water system a CRAC but its actual a CRAU (Computer Room Air Handling Unit). There is no AC (Air Conditioning) when using a chiller so I get it and using the term "Crack" is a generalization. If I am building a project and we have chilled or condenser water in the computer room I start to worry about a new set of issues, computer and water don't mix.
Data centers are always expanding, they often don't take into consideration the added heat load. They just keep pushing in more racks. One solution was a manifold piping system over head, with quick connects. You just place fan unit cooler on top of the new data rack and hook up the quick connect flexible refrigeration lines that's it. The main cooling unit has a large reservoir to accommodate multiple fan units. It was years ago when I helped install the manifold piping system, and I can't remember what it was called. Maybe someone knows the system name.
why there are gas pipes for the outdoor unit of a water-cooled in-row unit?
Can you provide me ppt presentation for like this without voice for 2 different topics?
Dear sir please. Make a video all in hindi ....
can i get HAP file for these room ?
Hey Paul, the VRF video is missing. Can you upload this one again?
New VRF unit video here:➡️ czcams.com/video/4i1XgcP1tmw/video.html
What you described as a 'CRAC' unit is actually a 'CRAH' unit.
Depends however on the location of the mechanical cooling equipment. CRAC units include the mechanical cooling system at each unit. CRAHUs are chill water fan systems and rely on remote Chillers type systems.
The picture at 0:17 is not a recommended way for stacking racks, it should be like Cold-Cold front or hot-hot front.
He addresses this specifically at 4:00.
Why cant I see the VRF video? It's not available does it say..
Was deleted. Check our supermarket hvac video for vrf basics
@@EngineeringMindset aright will do so, thx!
New VRF unit video here:➡️ czcams.com/video/4i1XgcP1tmw/video.html
And you forgot the platform that everyone who watch this video definitely uses CZcams 0:37

I hope you put an Arabic language as translation
versatemp in a data centre, not very efficient
You are too fast in explanation, otherwise it is good !
All of these are junk. I run several crappy black pipes 7ft under ground for 200ft and pump in 48F air into my greenhouse and room year around. Can't get more efficient than 1 fan.
