brilliant video mate.....long live Ron. I am an electronics guy...still understood the operation of the TXV pretty clearly.

great video Mr.walker. I recently graduated from the F.C.C. h.v.a.c. program.your videos are a great learning tool they help me stay on top of thins.keep it up.......wish you all the best....

Great video. Understood the workings of TXV in a flash! Thanks Ron

Excellent video it has answered some of the mystery I had as to why they have screen and also cool tip to see if the partial freezing or low freon flowing can be checked by warming the bulb or adjusting the spring pressure to control the superheat.

Best explanation of the TXV I’ve ever seen thank you

That was excellent, I totally understand the TXV. Thank you, I'm deff going to check out your other vids.

Long loooong life to u bro.. U r simply the best and ur videos are helping me allot. Thanks

Excellent explanation, for those who want to understand the refrigeration process. Thanks my friends excellent work.

Great class on the txv.

Full of nuances 👍 Thank you.

Thank you for the video it was very educational an eye opener god bless you

very good explanation of the theory behind the txv. I am no fan of txv to be honest I run into more head scratchers dealing with txv's than with pistons, mainly run into starving evap coils on 5-6 year old units eventually a txv gets stuck and turns into what I see as a fixed oriphas end up having to charge these systems with subcool making sure I am getting liquid and by superheat, due to faulty txv's surviving poor r22 to 410a change outs 5-6 years ago. Its getting easier for me now to identify that crap out here in the field. Its educational to watch your video and see how a txv is suppose to work, but out in the field I find hardly working txv's allot and they are a headache, client cannot afford major repair etc. I like pistons i wish the manufacturers could make pistons work txv's really bug me when I have starving evap coils with high super heat and good sub cools, especially on heat pumps!!! Thanks for the video sir. Oh and the rookie trying to figure out how to make a hole for the equalizer tube, use your torches.... Your welcome, say a prayer for me out here please..

excellent i fully comprehend it now ! thank you

Ron- thanks for the video. I'm going through them one by one. Questions: Why does the refrigerant not simply flash cool when it exits the metering device? Is it just pressure differentials that move the refrigerant along? Should all older metering devices be retrofitted with TXV's? what's the advantage? (Video) Why not have an heat exchanger between the compressor and the condensor coil? I'm guessing thats what a de-superheater is. Only time I've heard of them is for ground source heat pumps. Why? With the much superior transfer properties of water, and the need for heat, why discard it to air? Put the condensor fan on an temperature differential controller, controlled by a sensor on the exchanger. If the hydronic/gas exchanger takes the heat and transfers it to the Domestic hot water tank, the condenser fan never runs, saving energy, wear, and noise. And gives free hot water, for the price of running a circulator. Seems a basic addition to any southern climate condenser. What am I missing?

The answer is clear. I can not commit to a TxV valve without understanding the heat pump

Thank you!

Nice video!!

Thank you very very much!!! sir

Thanks my hats off to the person who though up the TXV valve . Was it one person or many playing off each others ideas ?

Great video. Please share more videos.

Did you get a chance to answer my question, I emailed you a couple of days ago. On how to wire the low-voltage condensation pump.

I recently was hired as an adjunct Instructor for a local technical college teaching HVAC. Since then I have begun my search for applicable and detailed training aids to help illustrate the details of how the process of heat transfer works. However, other than KZfaq videos like yours, I have not been able to find specifically what I am looking for. That being said I was hoping to find some open source flash animations or power point animations that I could use without license in my class. I do not have the time or resources to be developing or purchase my own at this time. Do you have any suggestions as to where I could find any useful visual aids to help me teach my courses? Thanks.

Thanks sir

Honestely thanks for your you tube posting. it helping us maintence personal in apartment,, how to covert most not all but the one's we can save into 410a.. God bless You. if i offended you with the God bless you. i opalogize... GOD BLESS YOU... Thanks.

It should be 14 deg F not 14 psig if temp is what we are after because 91psig-67psig is 24psig thus 91psig is equal to 54deg and 67psig is 40degF. I hope my understanding is right.

thanks

can you tell me what is the difference between ford air conditioning and normal air conditoning?

Can you make a video on how to wire a rectorseal SS500EP secondary pan water safty switch. Also how to wire up a rectorseal SS500EP WITH A SS1 PRIMARY float safety switch . Thank u

I would like to know if i can clean an expension valve ea36yd-106

I didn't understand how 91 psig - 67 psig = 14 psig. Did the spring account for the missing 10 psig?

pls advice i have problem in refrigeration system it is bitzer 15 hp it is new system while running the whole condenser unit vibrating i can't find out the problem orifice used no 2 expansion valve TE_5 It is a major issue for me pls help thank u

ODT 85degrees R22 txv 4ton package unit suction temp to the compressor was 25 degrees head psi was 425 is this a TXV issue or a blockage ? SAL

Epic

I am interested in HVAC certification program and was wanting to know if a great online school to get this certificate/diploma. Does anyone have recommendations?

what causes the txv to freeze

Do you know where I could take the NATE exam once I complete the training.

I would like some Nate information if possible thank you.

In Uk studying RAC certificate level 1.Our wrkshop tutor is quite faster and he's done couple of demos that I ddnt know what was going on and at least why we were doing it.I need to pass my course but I thnk I have limited resources such as xtra help on wrkshop demos plus at least notes prior to demos so u know what u on about etc....So plz The great RON help me with a an ideal plan to pass and fully understand my wrkshop tasks.Currently;we've done two tasks...i.e gauge fitting +system pumping dwn then setting low pressure control. Whereas i fully understood gauge fitting plus pump dwn but Lp switch setting is a bit tricky and dnt understand the whole concept with task questions like how to repair Leaks from Lp controls..jesus! Plz help sir.

Rat B. ✔️

Help me please!! lol I condemned a fairly new txv on a call.. Gas A/C 2heat 2cool single compressor with an unloader on a trane system. Installed mid summer last year..Bottom of evap frozen back to compressor, split gas A/C..Thawed system for a day, came back next day, running to specs with a 19 degree delta t.. freezes back up the next day under heavy load. cycling on low pressure, but head pressure rising. Filters clean, fan motor running every time I laid eyes on it.. txv will go in Monday, I hope it works

Nice video!!
