Can you please make a video about subcooling and super heat

[@paulotieno5245]

Thank you ,it's educational item.

[@AmanKhan-ec6lg]

Why your videos are not coming in hindi version??

[@Outbreax000]

So, I’ve looked at about four different videos trying to figure out how refrigerants work and they have all left me with more questions than answers. Your video was actually the first one where I felt like I totally understood what a refrigerant is. Thanks a lot mate!!

[@CameronWilson-s4j]

as a civil engineer who always hated this stuff, being forced to recently understand it, the videos you make are super helpful.

[@Lalosupp]

Why did you need to learn this?

[@bigjimfanning]

Watched four different videos on this subject and all left me scratching my head. Then I watched this video with the same exact terminology and theory but explained completely different than the others and it made perfect sense. Goes to show why good teachers are important. You can have a bunch of teachers teaching on the same subject matter but one makes sense and the others don’t. The way you are being taught is just as important as what your being taught. Great Job!!

Phenomenal explanation! You just helped me turn months of confusion, uncertainty and anxiety into understanding. I realize that the information I was being taught was indeed correct, but somehow since I am not working in the field, I was unable to connect the dots to understand as I do now. Thank You very much!

THIS. This is the best video to ever explain the compression refrigeration cycle thank you so much.

[@Ratlins9]

Always had some trouble understanding the concept of refrigeration. This video gave a thorough explanation with step by step process of the entire cycle. The numbered illustration which was animated provided me a clear understanding of the refrigeration process. For someone who sometimes struggled in school, this was a godsend. Thanks very much.

The emf generated by the external energy , separates charge carrier (electron) from the atom of copper coil in generator similarly the energy breaks the atom of refregerent to make it vapor and hence the liquid becomes somewhat cooler. Thanks from BD.

Very well explained and demonstrated, with perfect analogies, as you usually do in your videos. Loved it. Keep it up.

[@heperez3966]

Excellent video!

[@vicferrari89]

This was a nice explaination EXCEPT for two major issues. 1. The refrigerant in State-1 is a superheated vapor and is NOT in its saturation state! If it was, this would pose a problem to the compressor which is a "vapor" pump. It can not and does not want to see any liquid! 2. Inversly, in State-2, at the output of the condenser, the refrigerant is in a high temperature-high pressure sub-cooled liquid. The refrigerant needs to be 100% sub-cooled liquid when entering the evaporator. This is where you want all of the absorbing of heat going on, not in the liquid line.

[@Luke-ey3my]

It's worth mentioning that the vapor entering the compressor is superheated, and the liquid entering the TEV is sub-cooled. Remember folks condensers reject latent heat and evaporators absorb latent heat.

[@carloslugo8353]

Is it bad that I learn more in these videos than I do at school ?

[@mosesneri5060]

Could you go more into detail for the evaporator stage. Everything makes sense and was easy to understand until the evaporator cycle

[@Redtooth75]

Temperature and pressure are related. The saturation temperature of a substance is the temp at which it will change state from a vapor to a liquid or vice versa. The saturation temp depends on pressure. The high temp high pressure liquid refrigerant passes through the metering device. The metering device and compressor creates a pressure differential. So when the refrigerant passes through the metering device its pressure and temperature drops. So now the refrigerant temperature and saturation temperature is lower than the temperature in the space we are trying to cool. Heat moves from hot to cold so when air is passed through the evaporator coil it the refrigerant absorbs heat from the air. The refrigerant will remain as a liquid until it has absorbed enough heat to evaporate. The state change from a liquid to a vapor is where most of the cooling comes from. The liquid refrigerant has to absorb a lot of heat before it will evaporate and start increasing in temperature.

[@Hsbkxkx]

so correct me if i'm wrong but long story short, the refrigerant gets heated up (pressurized), all that heat is blown outside to make it easier to cool down when its depressurized, then once its depressurized, it passes across another fan that blows cooled air inside?

[@gooddeedsleadto7499]

I have worked as mechanical engineer for many years for a major petrochemical refinery. among other maintenance areas of Lube and Fuel refineries I was in charge of the FEU unit where and the refrigeration unit was part it to get the wax out. I was also responsible for the centrifugal compressor and was trained to troubleshoot the refrigeration centrifugal compressor doing vibration analysis using Bentley Nevada instruments. We used to send out the control valves for calibration to the workshop and the instrumentation department would get the requirements from operations for calibration of TXV? Could u please do a video on calibration of TXV? Thanks, the video was super interesting

[@gooddeedsleadto7499]

Refrigerant also condenses at higher temperature at higher pressure and it facilitates dumping out heat just like it evaporates at lower temperature at lower pressure and it facilitated absorption of heat?

The Compressor compresses from state 1 to 2, and increases pressure, and temperature. Yet the (T, s) graph on the top left shows that the transformation 1 to 2 is isothermal (T is constant). Is the (T, s) graph wrong? Sorry if I missed something.
