How Do Flash Drives Work?
The Engineering Mindset nice video
Can you please make a video about subcooling and super heat
Thank you ,it's educational item.
Why your videos are not coming in hindi version??
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!!
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!!
as a civil engineer who always hated this stuff, being forced to recently understand it, the videos you make are super helpful.
Why did you need to learn this?
Who needs college when you got the EGINEERING MINDSET!!! Thanks bro...
Keep up the great work...
Thank you, we can only help teach you, we can't certify unfortunately.
@@EngineeringMindset nicely teaching sir,
@@EngineeringMindset You make it easier to pass for certification. Thank you for what you do.
13,995 subs back in 2017 (1:46) to now 2.17M. That wasn't earned by making trendy videos either, well deserved. Thank you for these videos!
Thank you so much, for the best explanation.
VERY HELPFUL HOW EXPANSION VALVE WORK NICE THANK YOU MR PAUL
thank you so much you cleared my some doubt in this video, pls sir its my request u will make some video about static pressure in HVAC and how they calculated
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 is the best explanation video that I've ever watched! Thank you!
Thanks very much! A really concise explanation.
great explanation, I'm greatful Muchas Gracias!
Really awesome videos i have ever came along this way of explanation till now you're explaining with best examples we are learning very quickly......
VERY HELPFULL ELABORATE EXPLANATION...THANK YOU, SIR
Thanks for this video. This is very very good. Easy to understand.
Thank you very much for this.
another great lesson from the engineering mindset!thank you1
One of best video explanation about refrigerated cycle... Thank you sir.....
Thanks for this video very useful and informative.
I just had a lightbulb moment! Thanks for explaining it so clearly👍🏻
THIS. This is the best video to ever explain the compression refrigeration cycle thank you so much.
Thank you very much for posting helps me understand HVAC systems and how coolants work
Dear sir, so far the best video ever seen with the clear status of the refrigerant, god bless you sir, really a good video!
Lots of valuable information God bless you man it worth its weight in gold
Very good explanation
Great video. Thanks for sharing.
Best explanation with visuals I’ve seen 👏🏼 thank you
Thank you so much. Yours is an excellent description of the processes and the sciences behind each stage by explaining it with familiar examples like boiling water and spray can.
Great video. Very well explained. Thanks a ton. The world needs teachers like you.
I feel like collecting all my “likes” on other videos on this subject and placing them here
Very clear and easy eXplanation
Glad it was helpful! we have a newer version "Supermarket HVAC" check it out
Very well explained and demonstrated, with perfect analogies, as you usually do in your videos. Loved it. Keep it up.
Helpful, thank you
Best explain and clearly I am understanding. thank you so much..pls continue to update many videos sir.pls....
This is by far the most informative and easiest explanation of how system works ! Thanks so much!
Thanks a lot sir ,great education.
thanks, very well explained
i had seen many vidoes in famous chanel to understand that principe of refrigerants, this video is the best thanks 👍
Incredible explanation 👏
Thanks, very nice and good explanation
Thank you a lot teacher! Very intresting!
Your video made my every doubt clear, your explanation was very simple but damn high concept,
Thanks brother, I will suggest other people to subscribe your channel, your explanation is superb.
GREAT LEARNING TOOLS.
It's the best video I've watched to explain how refrigerant work
Minh Nguyễn hello
Best video I've watched to explain how a fridge works. Thank you.
I thought it said refrigerant not a fridge
@@VenomSkywalker. refrigerant is just the stuff inside the lines that causes the fridge to get cold. Same thing as an air conditioner just slightly different for lower temps
it is very helpful and not complicated. thanks:)
This is a really good video. I learnt much
Pssst. Guess what? This channel is uploading thousands of dollars worth of easily digestible knowledge. 😂 it’s insane how good this channel is and that fact it’s free makes me laugh. I still paid for trade school but still this is literally the place to learn. I back up all my learning with this channel.
simple, superb and nice explanation. keep it up👌
Thank you
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.
Just wait till next summer. You will have forgotten everything, so bookmark this video.
@@skipwin9895 So true 🤣🤣
Thank you so much for the videos
Thanks for this informative video, but what is the difference between vapour and steam?
There are no other best videos than this one. You are in right place! Go Ahead! and you won't regret to give me thanks!
you're awesome thanks!!
Thanks for the knowledge my dude
best ac explaination after watching countless videos so far
very nice video! well informed.
Great explaination
Thank you for the video
great video as always!
Thank you so much,
Love it, make very clear
Thanks to the information sir
great explanation
Thank so much Sir...
Way better than what I learned in school hands down ..
Great graphics and logical explanation. However doesn't the refrigerant need to be superheated and not saturated before it enters the compressor?
Excellent video!
Thx
Thank you 🥰
same tutorial content. this video is very useful for those who are just learning
Thank you for taking time to make this video. Awesome work
You the man.
Awesome
Thanks for the great videos, here is a large coffee brother!
Really appreciated, thank you for supporting us
very good .
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.
Mindset you did it good
thaank you thnk you thnk you
My teacher couldn’t teach this. I thank you much
Super useful information. Very well done. Helped me out a lot.
good job
Very nice
Informative. Now do you have a video for Vapour absorption system of Refrigeration / A.C
Yes, please check out videos
Hi Paul
I've been following your channel for a very long time. Your contents are vivid and unique. I'm learning about HVAC too, so I would appreciate if you help me suggesting the book which you've been following for HVAC. Keep doing your good work.
Thank you.
There is no one book unfortunately, you need to read everything from everywhere. Or watch our videos!
@@EngineeringMindset than I will just watch your videos XD
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.
Very good video
What a great video.
That's a proper good video!
Expansion valve
1. Saturated liquidity
2. Liquid/ vapor mixer
3.saturated vapour
Best video i have seen
Great video, thank you. It may be a silly question, but what effect (if any) does the boiling point of a refrigerant have on the temperature that can be achieved?
If I wanted to make a freezer capable of reducing the temperature to -40 C what refrigerants should I consider?
Pls. Make a video presentation also of pressure switch, thermistor and other ac unit accesories.
Seen our new pressure switch video? Link: th-cam.com/video/YG81w0HFXNc/w-d-xo.html
Very nicely done how much would it cost for a 3 bedroom semi detached.
Sir thanks 🙏
Could you go more into detail for the evaporator stage. Everything makes sense and was easy to understand until the evaporator cycle
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.
ty
Can you tell me where the Best position is to measure tue superheat and subcooling temperature? I think directly before the TXV and directly before the compressor. But in many videos the technicians measure at the two connectors of the outside unit. Can this be correct and accurate?
Is it bad that I learn more in these videos than I do at school ?
