Great video, choosing HVAC as a career path i'm sure you're surprised English is not a strong point. You make it easy to get it from brain to mouth. Will show every Tech.
Great video Brian, I steal your ways of explaining things a lot and it really helps some of our younger guys out. Could you do a long video on non-invasive testing? I read your article, but I would like to see it on like a sealed, self contained refrigeration system because I would like to start doing it and possibly showing some of our other guys so they can do it on tune-ups and such so they quit instantly going for their gauges.
Since some are picking gnat droppings out of pepper, Lets keep PSIA and PSIG in their proper place (a pressure point). Also remember oh is a letter and zero is a number. Greg as always thanks for your excellent information. Perhaps some day you can do a teach on HVAC and metaphysics. Thanks again.
nice video bryan. looking for more of your video. i hope it also has a r404a im having a trouble with that refrigiration especially on the suction line temperature.
Appreciate everything you do, but had to adjust the speed to 0.75 to follow along, just saying. LOL. Or could you have about 4 beers before recording !!!
Thank you for a great video. I have a question that I could not find the answer to in the book. I found a couple of recovery cylinders at my work that have refrigerant in them. The first was a no-brainer - it was R22 and matched up perfectly to the PT chart. The other is an R22 substitute. When trying to match it up using the slider app, do I use DEW or BUBBLE point to match it up? I think the correct answer is Bubble, which pretty much makes it look like R422D, but I am not sure. We used to have three R22 chillers and I know at some point one of them was retrofitted with a "drop in replacement" while the other two were still on original R22. All three have since been replaced. Thanks in advance for your help.
That's an interesting material property. At first glance it would seem that glide would materially decrease the thermodynamic efficiency of a refrigeration system in the same manner that superheat does, and would thus be an undesirable trait...
Sub- bub and Super-dew. So we just keep measuring temp and pressure at the service valves just like always but make sure we are referencing dew point when measuring superheat at suction line and bubble point when measuring subcool at liquid line?
Very good explanation, Thank You!
Best explanation I have ever heard. Thank you
The explanation with the horizon, was really good.

Great illustrations with the horizon to teacher
Sir, Thank you very much for explanation. Now I understand

Extremely helpful. Thank you.
Great guide 👍
Awesome analogy. 😎👍
Good explanation
nice video bryan. looking for more of your video. i hope it also has a r404a im having a trouble with that refrigiration especially on the suction line temperature.
Love it. Keep on keeping on
Dew point for the wet line (suction line)
Bubble for the line with bubbles (liquid line)

Why is the dew point higher in temperature if that's when a liquid should be cooling off? Shouldn't it have a cooler temperature?
Power Factor next? In depth on PSC motors would be great too.

Yes i really need this info.
Makes sense to me!
good job
Bubcool and Dewperheat, the newest Pokemon?
BubCOOL and DuperHEAT
Would be graet if it was done automatic on your manifold. Dew on suction, bubble on high side.
crystal clear
nice video.but i suffer to understand your english.it'so fast but charming one.good luck
