(TXV) Thermostatic Expansion Valve Operation with Pressures! 3 HVAC Scenarios!

In this HVAC Training Video, I show how the TXV works by showing the TEV & TXV internals, components, function, measurement of pressures, temperatures, superheat and the amount of saturated refrigerant traveling through the evaporator coil. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

So I just moved from installing to service, and I've been watching your videos since day 1 of hvac school. I just want to say that your videos have helped so much in the past, and I look forward to continue learning from you. You help so many people out, and you deserve major props man. Thanks for your time and your very informative videos. 👍

Hands down, the best explanation of a TXV...

[jasonjohnsonHVAC]

Outstanding explanation. You are definitely one of the best at explaining operation, diagnosis and repair.

[jeremymcguire]

After watching dozens of your videos over the last several months and learning something new from each of them, I just ordered a bundle of the paperback, workbook, and quick reference cards from your website. Thank you for your work making these educational videos, you have a gift as a teacher.

[NMranchhand]

Gosh, you’re getting great at explaining complex HVAC concepts succinctly!

[edlauren]

I am a licensed hvac/refrigeration contractor. I live your videos! Thank you! N

[chrisdeanndavison]

What a great explanation and animations!

[TurboDieselFury]

That was the best explanation of super-heat that I have ever heard. Thanks.

[resurgensix]

Starting classes soon and your videos are really helping me get ahead of the curve. Much respect from Miami Beach.

[indoorcomfort]

As always, excellent content!!! Thanks from Indoor Comfort.

I was watching an Emerson TXV training video on the Jackson Systems channel. Someone asked the instructor about testing a TXV part. Apparently, you can cool them with ice water on the bulb/powerhead to close and use your body heat to warm them up to open. Don't apply a flame or anything. You have blow through the valve while cooling/warming to feel the valve close and reopen. I tried this with an automotive TXV and it works. If anyone wants to get a "feel" for the valve operation.

[jimmysegovia]

good one Craig!!!! thank you for sharing!!!! man you really know your stuff.

[seank]

G'Damn. I am nowhere near certified or have ever worked on AC, but considering I potentially have a tXV issue with my system this did an AMAZING job explaining it! Thank you!

[lugongguo]

I totally understood TXV after watching this video. Thanks a lot!

[marklennon]

Thank you again for providing excellent information.
Ps; your books are also an excellent source of information.

[NMranchhand]

That was really one of your best lessons (among many) vis-a-vis the integrated use of graphics and spoken explanation.
One suggestion though: you didn’t direct student attention to the changes in your brilliant graphic of the mix of dark blue/light blue. I only noticed late that they were changing to reflect the position of the liquid up and down the evaporator. I think many students might not have gotten the implication of controlling how much of the evaporator is exposed to the saturated state and thus the latent heat of evaporation, which, of course, is the only heat-absorbing state since the temperature cannot rise. I think this terrific aspect of your video deserves spoken attention with the latent heat eye-opener.

[SubramaniamLakshminarayanan]

Thank you for explaining superheat so nicely. Being new to HVAC, I was always in confusion over sc and sh. Now to look for and learn on subcooling.

Science+ technology+ experience = success....salutes from an amateur.
