Electronic Expansion Valve - How it works ETS 5M HVAC

Electronic expansion valve. In this video we'll be covering EEV electronic expansion valve to learn how they work and where they are used. We learn basic refrigeration cycle, compressor, condenser, evaporator and different types of expansion valves.
Correction:
06:15 The bulb refrigerant expands to *OPEN* the valve, not close the valve. Letting more refrigerant in.
06:22 *CLOSE* the valve, not open the valve

I’ve been an HVAC tech for close to 20 years now and I still seek out education and watch various YouTube channels. This is one of the absolute best!

[JogBird]

this channel does sponsorerd videos the right way

[ralphpeischl]

This has been one of the best explanation of a expansion valve I seen in the 45 years I been in the HVAC field .

Honestly this video was more educational than i got in school. Great pictures, great quality, great diagrams, English is clear and understandable, all around great vid. Need more like this on Turbines, Industrial refrigeration and more on electrical/pneumatic controllers.

Amazing job by Engineering Mindset!

Just after 6:00 of the video prompted me to scratch my head and review how these expansion valves work. I was puzzled when you said the TXV reacts to close down when superheat is too high, and open when superheat is too low. This is backwards compared to what I would expect, since high superheat is crying for more refrigerant flow, and low superheat puts the compressor at risk of receiving liquid refrigerant if flow were to increase further. Fortunately there is an excellent video describing this in more detail, done by the same author, titled "How TXV works..."! I believe that video explains the process correctly, high superheat leads to the TXV OPENING, increasing flow, not closing down. Then I opened the video description here and saw that you already acknowledged that minor error. It's too bad we can't do Youtube annotations any more. Correcting that on the screen at the time stamp would have been much more clear.

Once again, you've presented material in a video that's easy to understand by giving the viewer that "OOOHHHH" or "AAAAHHHH" moment! Obviously this new valve's technology will allow a much more finite adjustment of freon for a more constant temperature. I LIKE IT!

The best video on how electronic expansion valves work! Keep up the good work! 👏💯

[tedlahm]

Sir: Have not heard from you in some time. Always welcome information.
Wonderful graphics. thank you

This is one of the best education channels I have found to be very useful especially when it comes to new technologies and innovations. Thank you!

[delrey-p]

this page has taught me so much and given me a tonne of confidence with my role. I thought that a change of career into fridge/hvac would've been a difficult one and it looked daunting as hell at first but you've helped massively. Big thank you.

[samerarab]

Because of this page, I open YouTube channel.. We want a video discuss about renewable energy (solar systems)

[mohamedabujreda]

what a great way to explain the EEV function!! thanks guys!

[toyinorodare]

Thank you for this video.
I am reading the Refrigeration and Air conditioning Technology(9th edition) and this video explained everything on Electronic Expansion Valve in visual and simple way.

[alexandrossoteriou]

Thank you, big fan of your work!
I would like to suggest a future video. Correlation between the EEV and an inverter compressor as well as more details on EEVs and PID control. (and how all these can be observed on a monitoring system).
Again thank you for your video. Very clear and punctual! Keep them coming!

[shrikedecil]

That's a brilliant decoupling of the two separate things that might need repair.

[khalidh]

Thanks a lot, it's very clear and well explained I have truly learned something today.

[yamazaheer]

Very well explained, thank you very much.

[garrithsmith]

Popped up on my homepage, curious to see how an expansion valve works, and what an amazing video. I love videos like these, as you feel your skill level increase after watching. Just another thing in your toolbox for when and if you come across it.

[SuburbanDon]

This was really good. I never knew the finer points abour refrigeration.
