Heat Pump 08 EXV EEV Electronic Expansion Valve

As efficiency demands rise and the need to operate at lower and lower temperatures, Electronic Expansion valves are becoming commonplace.
In this video we discuss some of the basic operation and and bypass methods of EVX (EEV) operation including using a thermal imager.

Special thanks to:
JD Kelly (student_of_Hvac) for the digital art.
Carel for letting us use their cutaway CO2 valve
Emerson for letting us use a video clip and slide of their EEV.

This video only scratched the surface, here is some more in depth information for electronic expansion valves.

Any videos how to troubleshoot EXV EEV's? Is it check the pressure & voltage? AC or DC voltage? Is it the same in mini split? Help me learn please! 😢😅🎉

show me how to calculate seer on a running machine pla :/

The FLIR camera really communicates the message. Great. Simply great.

Mr. Ty, , when you start electrical course???

Is once a screw Pen valve And the other is a gillertine. One It's highly more accurate at regulating But the other one A far more simpler and cheaper design. The valve needs to be Regulated through a very sophisticated monitoring system. I'm pretty sure the guillotine isn't so strict. The actual sensors sensors are probably digital with the Guilloting an amalog with the Valve. Cost difference must be outrageous And a constant headache calibrating at any point. While a girl'valentine is digital Position 1234 that's probably it. I'm regulated most likely by a simple silhouette system.

Can a eev magnet be used as a lls magnet?

[WallaceRoseVincent]

Can old piston metering systems be converted to use an electronic txv? Do they make kits to do that? Do those systems replace the defrost board wirh a controller board (if they are available)?

Ty great demo. Which Flir camera are you using

[Studentofhvac]

Video editing is really good. Great information!

Another beautiful demonstration. Keep up the great work!🤝
