The new York chillers have a 12V DV battery that keeps the shaft of the magnetic bearing levitating and it will slowly spin the rpms on the shaft down when you have a power loss instead of the shaft just free spinning and falling very cool design. They also have a marine option you can buy and it includes hinges on the shells so you can clean the tubes out instead of having to use a chain fall to take the end caps off the tubes, but watch out it you order the marine version the blueprints don't include the total overall width of the chiller with the hinges they only include the width to the end of the frame the hinges add another 6 inches of width on the entire chiller (we had to cut and re wield the hinges back on )

handled chillers with multiple turbocor compressor, york ymc2 magnetic bearing and york yz magnetic bearing. the difference with turbocor with yz and ymc2 is turbocor needs multiple compressor in parallel to match a york single compressor tonnage.
this restrictions in danfoss turbocor compressor design mainly the fact that danfoss has only one patents on magnetic bearing technology while york has skf magnetic bearing technology patents and synchrony magnetic bearing technology patents. recently johnson controls, which is the parent company of york has acquired siemens synchrony magnetic bearing technology which secured the large tonnage compressor to york chillers.

As a bachelor student of Electrical and Electronic engineering, I find efficiency oriented engineering as a prime priority over gimmicks. In efficiency, reliability is key, I hope to find what differentiates the Turbocor Chiller from a traditional heat exchanger. But most of all, the 'Co' coefficient of heat exchange to energy input compared to similar systems.
One downfall I would not find acceptable with this kind of system is the lack of a reverse flow valve. I can see that water would not be a suitable means for evaporating with colder climates though haha.

We just had a new Smardt chiller installed in our building, and I wasn't sure what type it was. After watching this video, it appears to be a 3 stage turbocore chiller. The only difference is that the evaporator is in the mechanical room and the condenser is air cooled on the roof.

I pretty well got out of the trade about 26 yrs ago and only occasionally work on residential AC or RV AC. I was working on Trane RTAA Aircooled water chillers and they were top of the line at the time. This is badass! I had no idea things had advanced so much.

I have 3 chillers, with 2 of these compressors each, at one of the campuses I oversee. Now when I give tours to refrigeration mechanic students and explain how these work, I will talk a little less out of my behind, lol. Great video on the turbocors. Thank you

The magnetic bearings and the 2 stage compressor had my attention first, but then the shutdown system that turns the motor into a short term generator is a fantasic way to protect the whole machine.
Thank you for this video!

When the turbocor compressor was designed the engineers had hopes to eventually scale it down to be able to enter into the domestic refrigeration market. I rather doubt that will be pursued unless another design team

Could you make a video on how EKG machines work? There are only videos from a medical point of view, ir would be great one that explains the engineering behind the 12 leads, electrodes, etc. Your videos are great!

What happens upon failure of the inverter? I know the induced voltage on failure allows the magnetic bearings to still work on power failure, but on inverter failure wont it cause damage?

Do you have a simple block diagram consisting of major components of electrical from AC input down to motor winding? I just want to see how the power transforms until motor uses it.

Im not gonna lie I was a little scared of getting into HVAC but with this video helping me understand it a lot better I feel a little more confident working on the machinery

thanks. I really like your videos. Can you make video about industrial air compressor, and industrial refrigeration machine, using NH3? and how to check them regularly?

You should make a video about harmoics, that subject is quite confusing and I really don't understand how they form. It'll make for a good informative video.

Could you make a Video on how to build/design an AC unit? I'm really enjoying your work, and it inspires me for some Ideas, but I struggle to start a project.

Do evaporator water is just water or antifreeze added? obviously condenser water has antifungal and antibacterial chemicals in it since outdoor air is nasty.

Why do we use a open system for cooling the water back down? Why dont we use closed condensators instead of cooling towers as we would with a freon system?

Make no mistake, this IS a commercial, but an extremely well-done commercial packed with both generic and specific HVAC technical information. Well done.

Good video! I would like to learn about of all sensors of the car like: TPS, CKP, CMP, OXYGEN, MAF, MAF, IAT, ECT, etc. I hope that you can learn us that!

Can anyone explain why the turbocor chiller unable to operate when water entering into evaporator has higher temperature than water entering into condenser?

Why does it have a VFD and a soft start? A VFD can do everything a soft start can and makes the soft start redundant. Why install both devices?

Very impressive but firstly it be be extortionately expensive and secondly when it goes wrong it really will go wrong big time

They sound like jet engines and run 19000 rpm at 100%. Pretty cool i mess with them every now and then at work.
