I was wondering why they did that for a while.. when I first started doing service and checking static I was confused always seeing .5 on my mono-meter then seeing .2 had to call my supervisor to make sure nothing was wrong,😂😂😂

that looks like a complete mess 😮

Oddly enough, this fluid will be phased out in 2025. 3M’s Novec is hydrofluoroether and is what they are using. Ironically enough they are phasing out fluorinert as well which was used by Cray supercomputers 30 years ago for the same purpose. This is not a new idea, just a repeat when processors reach the limit of their efficiency and require more cooling. The chemicals are being phased out because they are PFAS or the forever chemicals messing with our endocrine systems. Essentially, transgender fish and infertility; but now affecting humans and land animals too. I am not here to judge whether you believe it is God, devil, destiny, or life choices that makes animals (including humans) transgender and have hormone issues that mess with sexual function and sexuality. Just science facts.

Heating or cooling unit for the tunnel.

The fluid is what originally was a cleaning fluid from 3M. It's dielectric (doesn't conduct electricity). Some solutions use DI water, but that poses problems with corrosion. The 3M product avoids those problems. A lot of manufacturers have moved past immersion to direct-to-chip water cooling. Immersion tanks pose logistical problems associated with lifting servers in/out of the tank as well as storing large volumes of fluid on site. Bitcoin mining has wholly embraced immersion cooling, others less so.

Plenum?

Awesome video 👏🏼

There are A1 class non-flammable less than 750 GWP. R153a, R446, and other 10.

Who decided the 750 GWP limit? Not regulations, not ASHRAE, not health and safety! IT IS SIMPLE A DAIKIN (patent holder of R32 in 2015) !!

Hi GWP when it leaks as in AC/refrigeration it is in a closed circuit circulate to transfer energy form inside to outside (cooling) or outside to inside (heating). You can not say R32 is friendly as it is A2L class flammable (can be internally explosive).

Why does he walk like that? I feel like that’s how Tony hinchcliffe walks

Hello

Sir i want your support.

The way the two were described could confuse some. A good example of a configurable control would be a frequency drives settings. You would establish things like rate of ramp speed or rotation. How it responds to various interlocks. A programmable control (PLC) runs a written program. It's ladder logic, if then statements. You used a grow room as an example. It's an excellent example actually because a PLC could precisely control a reheat system you recently covered. A PLC could slow an evaporator motor down while monitoring suction pressure , temp or both. It could modulate a stepper motor valve, controlling the flow of hot gas to a reheat coil and back to the condenser again while at the same time trying to maintain a certain head. I have very limited experience with them in terms of actually programming them but I have read how to program them and get it. And I love it to be honest. I wish I had the chance to work with them more often. A friend of mine retired from Emerson. He was a pretty talented controls tech in terms of working on a wide variety of systems. Cogen plants, nuclear facilities, research environments, HVAC/R systems and what not. His work was impeccable. He got Emerson to give me access to Allan Bradley PLC training online. I only had a limited opportunities working with controls which sucked because I really love the work to be honest. I'm actually working with a microgreen grower right now. Mold can take over a grow operation if RH is above 50%. I grow mushrooms as a hobby and that led to talking to commercial growers and learning about some of their issues. They're controlling lighting, temperature, humidity and CO2 levels. I'm hoping to eventually develop a reputation with these types of growers. Vertical warehouse farming is fascinating. Their greatest problem is energy. Its the main reason the majority of them fail from what I've been told. The cost of growing a pound of product is not cost effective in many instances. Elon Musks brother builds grow containers that are supposed to work well. Your channel is fascinating. I follow a lot of refrigeration mechanics on RUclips as well.

Wht i learnr from course is by the refering of dbt ,Rh and ershr we can find ADP ...is it right sir? Or any other calculations and can any one plz tell the correct definition of ADP?

What is a refrigerant cycle dehumidifier? A reheat system. My idea on the matter is designing a cooling system responsible for the sensible load and a a reheat system capable of handling the latent load. The reheat system would designed to use variable air speeds in order to enhance dehumidification. Return air bypass does seem like a good idea as well. I don't believe I've ever noticed it before. I'm using the term notice because I may have been working with one at some point but never noticed. I really love your channel.

I want and need to learn about these so bad.

I was experimenting with this back in the late 1980's and the results I experienced were mind blowing. Had I had the vision to pursue what I discovered I probably wouldn't be watching this right now if you know what I mean. I didn't experiment with it to humidify because I wasn't working with systems to justify the investment in time experimenting but using it to lower condensing temps/pressures made it a no brainer.

The commercials are brutal bro. An older engineer once told me water seeks a level and it can do it quickly regardless whether it's in a glass or a vapor.

I stopped watching the live feed after losing the abiliity to comment on RUclips.

Data center, big university, or big hospital. The hospital is a stretch but they usually dont have that many chillers.

Lol trying to use a natural disaster to get internet fame 😂 Goodluck to you.. Baka

Thought I’d seen some big chiller rooms. But damn.

Either data center or chip fab

Propane based

No shit noone makes r22 units anymore

12:23 Are we not increasing humidity when we move from right to left in a horizontal line ? We moved from 30% RH region to 60%RH region.

Tony, that’s my home branch. Good people over there!

Jessup, up near the prison...Been to a lot of supply houses up that way in a former life.

How did u calculate part load SHR . I mean the values to calculate part load SHR

I have 3 examples of psych chart processing I would like to see you do vedios on. 1st I would say you are very clear, and connect the practical very well with the visual explanations of the subjects you provide tutorial on. The 1st is the standard hvac process for units without outside air? The next is for the addition of a dehumidifier to a Hvac system. Assume the space condition is 72-degF, and 50%RH. The client trying to get RH to 35%RH. The 3rd is the same as the 2nd, but the introduction of a dessicant wheel. I would like to see how this is plot on the chart. The heating and dehumidification, and the wheel drying out the air to get to the 35%RH. Thanks. Let me know if you have any question?

In Canada at a post secondary facility and have had 8 Mitsubishi heat pumps for server rooms for 7 yrs. now .Many days @ minus 30 Deg C and just a few issues * mostly from exceeded line set lengths and assoc.pressure drop.They are dependable @minus 25 Deg C .

That’s a chilled water pipe and it looks like the trace heating has earthed of the AHU and the same with the 3 phase supply to the fan motor due to vibration Should be glands and wires should be secured better is my opinion 😢

They know it comes back as rain fog, dew or snow, right?
