These videos that you make are awesome. Great refreshers or study material (depending on where one is in their career), and I will/am taking full advantage of all of this.along with everyone else, thank you for your time and energy you put into these videos, especially with your team in the background to hear their questions. Both things I feel make more powerful videos than just reading a book or listening to a “lecture”.

I just want to stop by and say thanks for all your videos , very informative and helpful . Keep it up

Man thank you brother i have a mammoth air cooled chiller and all 3 of my banks the scrolls were running low saturations at 30 and tripping on low pressure to find out that some guy went happy on my flow valves and opened them all the way!

Awesome brother as usual . Thank you . Kindly make a complete video on electrical as well of chiller .

Thanks for doing this

Please look up digi scroll Operation, the unload solenoid acts as a pilot valve to lift the top of the scroll head.

Good evening, chiller yvaa york punctures in evaporator tubes, what do you suggest to fix it ? Frame size 033

Sir video helpful thanks but can you make screw compressor yvaa chiller and centeryfugal chiller compressor overhauling procedure and techniques videos if you can it's more helpful for us thanks again your efforts

So on the screw I’m guessing as it slides back it opens up and reduces the compression basically slowing down discharge velocity and reducing discharge pressure. Basically like the the quench area between the valves and piston on a combustion engine ?

Yes

So, the eductor uses the vapor's energy to accelerate and inject flow to the motor oil circuit like the water injectors on a steam engine use steam to inject water to the boiler?

So, the chiller runs or should run critically damped ? No undershoot or overshoot.

@@HVACTIME I really appreciate you. I’m 42 and recently quit my cushy school board Maintenace tech job to go work for a big mechanical company and I want to do the best I can. You content will help me succeed along with good work ethics and determination.

The eductor must create a Venturi effect.

It seems that it’s design is to basically create a turbulence to keep whatever oil that’s made it way through the system from separating from the refrigerant so it will make its way back to the suction side of the compressor. (Stratification) could be wrong just a guess.
