Keep doing what you are doing Y because this help us be a more effective teacher/ instructors in order to teacher our students the correct way of how a system works.
I've watched many videos on this topic and I still did not fully understand and now I've watched a few of your videos I understand it much better And Craig from acservicetech recommend this channel,
So the other day I opened up my evaporator to see if it needed cleaned. I noticed that my TXV’s sensing bulb isn’t insulated, just strapped to the pipe. Should I insulate it myself.? Or is it okay.?
Yeah it’s inside the box. I figured it wouldn’t be the biggest temp difference since it’s inside, but I might insulate it just for good measure. Is there a good insulation to use sir.?

If you're working on a system that has a fixed orifice so that would mean that you are checking superheat, and you check the superheat and it's correct. What chart are you using to tell you what your sub cooling should be on the condenser? I see the one you have written on the back of your superheat chart but where are you finding that information?
Its information I have gathered over the years, when I get. Back to my library I will source it. #1 manufactures methods for specific models always override anything anyone has to say. Superheat is very important with a fixed office but it dosen't dismiss sucbooling. The science behind it is important. Think of the condensors as a tank with liquid at the bottom and vapor at the top. As the outdoor temperature increases the vapor pressure increases. More pressure pushing against the liquid pushes more liquid out of the tank less sub cooled liquid. As the outdoor temperature drops the vapor pressure drops also and you are pushing less refregerant out of the tank more subcooled liquid. ruclips.net/video/waKHwkqy-uk/видео.html ruclips.net/video/L43H2PhzqcY/видео.html
Fantastic Ty, and thank you. I'll say this again, you're a natural at explaining how refrigeration systems operate. Quick Q: Does the TXV close down (variable orifice diameter decreases) as temperature of the TXV bulb increases? You probably already answered this question somewhere.
Short answer no but it's not that simple. The bulb pressure will push against pin, the spring and he suction pressure to open or increase orfice size. It is important to consider the suction pressure and spring pressure. The suction pressure pushes with the spring to close while the bulb pushes to open. Later I will do a video much more detailed. Bulb/ pressure, Spring pressure, and suction pressure all work together. www.achrnews.com/articles/140466-abcs-of-externally-equalized-txvs
Good job Ty. These videos are a great reference for those that might've forgotten a step or two.Is there an email address we can reach you at as growing technicians for some professional advice?
I'll say it again I paid thousands of dollars years ago and didn't get this much visual explanation! 😎👍 🥃🥃🍺🍺🍺🏌🍇 Stay safe. Retired(werk'n) keyboard super tech. Wear your safety glasses.
Nobody taught it better than Mr. Ty. His gas heat and refrigeration cycle notes and drawings are the best
Basement laying is excellent...loves ur videos sir

Simply amazing explanation. Ty you just simplfy things and make them so easy to understand.Thank you
Thank you for being a great teacher. Loved the cup illustration

And Craig from acservicetech recommend this channel,
Im glad I could help. Craig is awesome! I am so glad to know him.
Perfect explained. even with my poor English I understood. Thanhs
Your analogies are Off the chart, Thank you so much for
Tutorials
Thanks from Bangladesh.

If its outside the box it must be insulated. If it inside the box I prefer it insulated but some manufactures do not.
Yeah it’s inside the box. I figured it wouldn’t be the biggest temp difference since it’s inside, but I might insulate it just for good measure. Is there a good insulation to use sir.?
