I work for APC's parent company here in the EU and service these units almost every week. Thinking about how the unit controls the fan speed, you could actually make them react to the water temperature by switching some of the temperature probes. So that if you have more PCs connected to it without much load, the fans could idle and ramp up as the temperature rises.

TECH TIP for the Sawzall! The rocker plate closest to the base of the blade is to rest against what you're cutting to stabilize the cut.

For a large IT manufacturer I became the expert for water cooled racks, ours had an enclosed rack totally sealed, and a half unit like this on the side, the hold air got sucked in by fans from the back of the rack, through radiators that ran cold water through which then fed back to the front of the servers so it was actually recycling the air, it was actually very efficient because rather than cooling the room or corridor etc you just cooled the rack... I installed some of these in a well known racing team as they had them under their wind tunnel and were worried racks under the wind tunnel would heat up the bottom and give them wrong results... Best feature was magnetic spring loaded doors so in the event of power loss or not enough water etc it would fling open the doors so as not to overheat the servers and give time to fix the issues, the thing is you could manually do this, you can imagine the fun of trying to get the doors to fling open on passing colleagues... I also remember those connectors, they were a beast and at least they used to cost a fortune for the hoses, you could get a rack of fully loaded with blade servers and it would keep them cool... In learning how they work I admit I did pee water all over a customers data centre on a couple of occasions..

One of my former employers had an APC NetShelter for one of our two datacenter rooms... It was quite nice; we have an entire enclosed hot aisle for exhaust while the outside of the room was rather cool. It had two full-width A/C units with chillers on the roof for heat transfer of the coolant; we had the APC folks in regularly for maintenance, and the internals looked about like that did. Anytime you have water or condensation, you're going to have discoloration, scale, and other oddities on the exterior unless you're doing a daily inspection of your coolers, and that defeats the purpose of the network monitoring and redundancies built into these units. ;-)

Data center equipment like that is serviced very regularly. Because all of their servers and business relies on that equipment being up so they do spend a lot of money in ensuring that everything is service properly and at all manufacturing intervals and they also do that because they have contracts with the manufacturer where if they don't do it the warranties will be voided or it's part of the contracts where they come out at every X hours and service the equipment

I had 2 of these in a 3 rack setup for redundancy. (Rack, fan, rack,fan, rack) and they are great. Very noisy however to the point where you can hear them through a concrete wall. Mine had compressors inside the units and the hot coolant would get pumped up to roof heat exchangers. The water trays inside the units are because they can generate some SERIOUS water condensation. Probably over 1L every 10 minutes or so during rainy weeks, they were like those in door waterfall displays during the rainy season and the water pumps were making a lot of hours. We also always joked the 2 units could make the racks move at 100% flow.

Hey Linus! I would leave the bypass open a little. You're going from a large (3/4"?) to a smaller (1/2" I would guess?) hose on the discharge... that's going to build some head pressure, and it might be just fine but it will strain your pump way less if you give it a small outlet by leaving the bypass cracked.

@cesarpalmos8235 25 күн бұрын
@@killax7 I was a tradesman plumber for 7 years and have never had a problem using a new half with an old half of a union coupling. The whole purpose of a union coupling is quick and easy access to components at a frequent service interval. They seal with a rubber gasket. If it leaks, simply install a new gasket. Compression fittings are fittings that seal using tight tolerances. They mate metal on metal and are usually one time use only. Often the male and female side will distort to make a perfect seal, thus every compression fitting is slightly different and not compatible with other fittings. Compression fittings are the fittings you may be thinking of.

The side of the servers that exhaust hot air, is called the hot row. The In-row coolers draw the hot air (as high as 75 degrees F) across 72 inch radiators that circulates 43 degree F coolant from our outside cooling towers. The foam around the pipes is to prevent condensation and there is pump for the tray to remove any moisture from Datacenter. the fans are rated for 10,000 RPM sustained. These do not cool the fluid, they cool the air.

Data centers use water to air chillers. Because running air conditioning with the compressors and everything is extremely inefficient and very expensive at that level. So data centers usually have cold water non-potable piping running up and down the bays where if they ever need to install a chiller somewhere on the raised floor they can tap into a valve and install a new chiller and then the chillers usually face downward meaning it pumps the cold air into the floor and then in front of the servers there's four tiles with holes in it for the cold air to come out The hot air rises into the ceiling where the chillers suck from the top and usually the walls there's a handful of chillers around the walls of each bay. But that's why these don't have internal pumps or anything because those pipes that are run through data centers are already being pumped and under pressure

There should be a lead used to sense output temperature, on the units I've worked with it was just laying in front of the output fans. Grab it and hold it tightly in your hand - you'll get super speed fans in no time! No laptop required :-)

I mean where I live the regular tap water comes pretty close to those 7°C even during summer, wouldn't wanna use that probably cause of impurities building up over the years, but it's probably a workable solution with some filtering.

Old tech that we used in our DC's where we had issues with CFM. These things eat power. We moved all our DC's to pull in ambient air and evac hot air out of the building. It was cheaper to cool ambient air then try to cool recycled hot air. This required sealed racks and control of hot and cool zones. But this same design can be added to small areas (Home wiring closets and small shop DC's)

This is kind of my dream. There is a serious Irony in my home. I live in an ironic state where my old home doesn't cost much to heat per se, because my office is so toasty from my wife and I having gaming PCs here as our daily drivers. So in the middle of the winter, I am dressed for the beach, until I want to grab a glass of water, when freeze my ass going to the kitchen. If I turned the heat up for the rest of the house, then the office would be so hot that I would be sweating with the window open. It has occurred to me that the dream would really be to have two heat loops. A summer loop with an outside radiator, and a winter loop that can dump into the A/C system to distribute heat through the whole house.
@Demoralized88 24 күн бұрын
I mean, this is why Central heating/cooling has return vents along with the supply registers. It's supposed to recirc the air when the Fan is running, to greatly reduce temp differances between rooms and floors. Biggest problem is a lot of Thermostats only have auto/on settings for the Fan, so usually only circulate air when the AC or Furnace is running. Ideally, you'd want to set the fan to run every so often to even out the house, but need to find a Thermostat that supports this.

I never thought you'd show anything like this. I cool my house with a 3.5 ton Drake scroll chiller that circulates 50/50 ethylene glycol and water at 5 degrees C through six fan coil units totaling a 4.5 ton load. As a result I have a six zone A/C system. The load exceeds the chiller capacity because the chillers don't run all the time. I don't liquid cool my computer, but if I ever did, it would be very cool (pun intended) to use some chilled water. I doubt the chiller would notice.

As a viewer I actually prefer the content where Linus doesn't put himself directly in harms way(like fingers right in the path of a saw). I much prefer when content creators promote safe working conditions. A lot of people feel pressured to skimp on safety at work for various reasons and people end up maimed or dead because of it.
