Im always amazed at how creative these little engineering solutions are . Using the state of the superheated fluid to regulate the thermal expansion valve is actually a stroke of brilliance, its always incredible to see the ingenuity that went into designing the most obvious things.
The key component to your video was Doing the cut away on the valve. It gave me a clear understanding on how the TX valve operates. Good job. Thank you.

It suddenly expands to there's less energy per volume. Effectively the molecules that make the substance are therefore not going to collide as much because they have more space, so the temperature reduces.
These videos are fantastic. You’re the best Engineering Mindset, I love your passion for sharing your knowledge and animated clips. Just a great way to learn, through seeing physical movement of parts; liquids, lubricants, magnetic fields etc as well as your explanations. Just brilliant!
6:13, it is the opposite: as the cooling load increases the superheated decreasese right?? PD: in 6:32 they say the opposite... Nice video that contradicts itself :( Someone tell me pls if I am wrong :)
i know this is kinda an idiotic question and/or idea. but i acquired a refrigerated dryer that functions the same as explained in this video. i got it from my father, a dentist, who had to upgrade his euipment. i use pneumatic tools, but nothing expensive nor special. just the average Harbor Freight collection. so i don't care much to dry my air. my girlfriend bought these little monsters called axototls. I like them. But they require cold water, around 18C. And a water chiller for an aquarium runs at least $300 for one that actually uses refrigerant. It's a LOT OVERPRICED as I could buy a entire fridge for the same price. So I was wondering if I could use the chiller dryer as a water chiller instead, by removing the filter from the system, and adding a good 500gal/hr water pump that would push the aquarium water through instead of air. the concerns i have are regarding water pressure vs. air pressure, and possibility of a freeze up. This modified usage doesn't have to be perfect. Just keep the aquarium water ±2℃ of 18℃. Actually the axototls are fine down to around 10℃, and can go even lower for short periods of time. The danger is when the water is too warm, which room temperature is the borderline, as these animals lose their ability to process food and get bloated and die very quickly. So you can easily understand now why I promised to fix the issue for her as she was crying because she lost one, as she didn't even have a thermometer for the aquarium. I'm a die-hard DIYer, as I can trust and depend on my tools to last a lifetime, whereas 99% of products are a huge waste of money, as they are not made to last at all, instead purposely manufacted with a set life, that is the shortest amount of time they can get away with. Anyways, if I remove the filter that collects the water from the air when it is chilled, essentially that would allow for water to flow through instead of air, provided I use a water pump for circulation, correct? As without the filter it's basically just a closed loop that is chilled to a temperature that can be adjusted and set by adjustment of the TXV as you just illustrated in this video, essentially using it as a thermostat. I figure as long as I can provide a fast moving flow of the water, and have the TXV adjusted in the correct range to reach a constant, there should be no problems. As the aquarium holds 60 gallons, and the pump I bought for this project is actually made for pond filtration. It's 30 watts and pumps up to 500gal/h. But it's flow is completely adjustable from 0 to 500, and it can be used submersed or "inline" (not submersed) - i plan to use it inline so i can easily adjust the flow and and choose where the water intake and output are. The pump is made to deal with a lot of "stuff", such as clogs, power outage, high strain, etc but has built in solutions that will protect the pump from cooking. It says it can pump a column of water into the air to a height of 7'6". The make and model of refrigerated dryer I have is: model # WRA-0010-A69 made by: Apollo Dental Products. The rated flow is 10 SCFM. Standard operating inlet air pressure is 100 PSIG. Factory test pressures are: 144 PSIG LOW SIDE / 400 PSIG HIGH SIDE. Max inlet air pressure is 200 PSIG. I haven't had a chance yet to look up how the Suction Service Valve functions, but if anyone who helps or is just interested, I can post the electrical and refrigerant diagrams attached to the unit, as well as photos illustrating all parts and functions. I have it opened up right now, and to me, this thing seems simple, just like a window AC unit or minifridge. I just wanted to ask some of you who work with this equipment regularly, if what I intend to do is possible, and if there are any precautions or tips that might save me some time. I want to just go ahead and test it out, but I will wait a week for any replies, as this thing could maybe save me $300. I don't want to destroy it. Simply repurpose it. Thanks in advance to anyone who lends a hand! I don't want to be accused of SPAM, so I will wait for approval from you Paul, as this is your channel, to post a link to my website where I will have the diagrams and photos posted. Thanks again everyone! -patrick
The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The high-pressure liquid refrigerant entering the expansion valve is quite warm. This may be verified by feeling the liquid line at its connection to the expansion valve.
I remember the time during my apprenticeship our chef technician can not answer correctly of my question about what is the used of the sensing valve I’m not satisfied with his answer what I did was I bought expansion valve and I cut it in a lengthwise just to understand how it works just like you did lol..that was my unforgettable moment of being a refrigeration/airconditioning technician
Well if the valve closes when the cooling load is less but the compressor might still be on, wouldn’t that cause the system to burst? Is there any specific control system for that as well? Loved the explanation!
harinath prajapati - great question I think. Ike fun - correlating this to being cylindrical because of strength is short sighted. I am sure the pressure in this little cylinder is not that significant. Probably cost and ease of manufacturing is more of the driving force behind the design. I think it was an excellent question - you should not belittle people asking very valid questions.
I actually like that you've questioned it. You've looked at something, questioned why it is this way and considered how it can be improved. That's the engineering mindset. It's cylindrical for strength, ease of manufacturing, universal fit on any pipe and equal heat transfer.
In automotive TXVs (i've just laid my hands on one i'm going to play with) the sensing bulb is still cylindrical, but it's "drowned" inside the refrigerant flow so that heat is directly transferred to it, and not through a pipe that acts as an interface between the refrigerant and the bulb...
Sir hi plz ihave big problem ichange expansions valve for air-conditioning Skm in indoore unyte evaporateur to mucht voice noisy 4 luiquid gaz insupportable.😣 this ac 48000bth. Waht iwill do now its harde for welding cappilary. Im tired 😫
So the sensing bulb is hollow. But it has refrigerant inside the hollow cavity? So when you cut into one is the refrigerant released or do you have to add it before you put one into service?
Mind blown. Been in an apartment maintenance tech for almost a year and I'm just realizing the original installers never tied the bulb on the other side of the coils. Makes so much sense now. Thank you for this video
Hello Sir I'm fresher mechanical engineer.,how to know fully knowledge in hvac,plz guide me sir i given interview for gulf but not selected ,plz help me my dream is work in America, how is possible i work in America.
What are the symptoms if something is wrong with the expansion valve? If ice forms on the evaporator coils, can I fix it by reducing the flow of refrigerant?
Actually in auto AC coil icing is prevented by keeping flow steady (rather than decreasing it further) as evaporator refrigerant temp drops around 32F, so that the coil floods and the superheat becomes nil. That is, the TXV is acting as an AXV (automatic expansion valve) at that point. Still there's a compressor capacity control system should the return air temperature/refrigerant temperature drop down too much. However, gas cross charges are used as the control charge. Decreasing flow so that superheat climbs up actually results in the coil starving and progressively icing up from the inlet to the outlet.
Why is the sensing-bulb mounted directly behind the evaporator? Why not directly in front of the compressor? If the superheat behind the evaporator ist tuned perfectly to 1K, it could be 10 K before the compressor which should be unnecessary and inefficient. What do i think wrong?
I have a two cold storage temperature controller Error PrE it's meaning I know but The problem is pcb/circuit .But I'm going to turn it on manually now, If I do not want to use Expansion valub, there will be no problem. Please tell me something advice. Thank you 🙏🏻
Parker, Thermostatic TXV R-410A TX5N4. Indoor Coil:Vertical CAPF4961C Does this install OUTSIDE of the case? Looks like it does do you know if it does or not? Thanks
the main function of txv is to convrrt liquid phase to gaseous phase and to reduce temp to absorv surrounding heat outside the tubes.This is a application of Boyles Law,the txv is designef to automatically regulate the flow of fluid.Eduardo here.
The last ac tech that came to my house to service the unit moved the sensing bulb away from the pipe that it was attached to. Do you know why. Do you think the TXV is not working properly? Is this ok? Or should I put it back where it was? About how much does it cost to replace the TXV? Thank you so much.
I just watched this video out of curiosity for wanting to know how refrigerators work. Did't expect to understand anything. I'm amazed by the fact that i really could understand most of the parts.
i wish you'd talk a little slower,,,,,,,,,,,,,,,i know you can go back and watch again as much as you want or need to but with that british accent i miss a lot and i become frustrated and turn off the video,,,,,,,,,,just a suggestion though,,,,,,,,,,,,,,,other than that i do like the videos............
These videos are as good as it gets but just in case no ones pointed it out, it says “whats inside a filter dryer” a few mins in - that said your videos are great. If you can idiot proof them even more for me I’d love it. Cheers
ok very cool vid but I have a question in minute 4:16 you explain that the pin gets push by high pressure saturated liquid pushing the diaphragm up that pushes refrigerant to the sensing bulb and back and fort depending on the temp that you get from the evaporation coil so this refrigerant is never gets passed the diaphragm down to the pin? its only in the sensing bulb and capillary tubing and on top of the diaphragm? its independent from the refrigerant running in the lines right ?

You did a great job in clarifying the function of the Expansion valve.
a 2 TR TXV can handle the load of 1TR or 3TR if load varies like this?
But I don't understand why does passing the liquid through the small orifice makes the temperature drop
It suddenly expands to there's less energy per volume. Effectively the molecules that make the substance are therefore not going to collide as much because they have more space, so the temperature reduces.
Wow you look way less nerdy than you sound, mate!!😁

Why Sensing bulbs are cylindrical ? why not Crescent shaped to be fit over pipes n have more contact area instead of line contact in cylinder ?????

Everyone can easily understand..🙏🙏
If there is no air flow across the evaporator and superheat level is not reached, does the txv stay closed and not let any refrigerant to flow?
Thanking you for increasing my knowledge......
This is not a thermal expansion valve but thermostatic expansion valve.
