This quality of instruction is what would happen if university professors understood that the students are paying them for explanations of difficult concepts.
He spent 30 minutes explaining a couple of words. Poor teachers just give the definitions and then say now let’s calculate the superheat. The long explanation guarantees that the students understand the concept, then the calculations are easy. But to apply those calculations, you have to understand what you are calculating. Great job by the teacher.
1984 in Riverside community college California the professor talk about this same subject on the 1st week of principal of refrigeration I have no idea what he talking about. Now I understand it better. Thanks you teacher 😊. Just why blurr his face!??
Holy shit this just made subcool and superheat seem so elementary. Thank you my friend. It’s just the point of change in state of matter and how much measurable heat is transferred beyond that state of matter.
Great teacher ! Best "Saturation, Superheat, Subcooling" video I've watched and I've watched dozens on the topic. I feel like it finally clicked in my brain. I get it now. Glad I found your channel. I'm enjoying slowly going thru all your videos. Thanks for sharing your knowledge and experience with the public and teaching our young guys how to be the best techs they can be !
I have worked in the trade for almost 39 years, and taught it in school for 25 years! Ty, you get an A++ for enthusiasm! You are keeping these folks engaged and teaching them what they need to know in a way that is getting through to them! Great job Man! People who are commenting about terminology would never get through to these people. They would be shut down and tuned out in a heartbeat!
Many years ago I had a refrigeration class and teacher wasn’t that good at explaining a lot of things but I already knew a lot and understood what he was talking about, then I would re- interpret to the rest of the class so that they would get it. I wouldn’t have to help this guy at all, excellent explanation of superheat and sub cooling. I’m going to watch everything he has out here.
I know there is no many instructors like this guy. God bless me a lot in the moment I found this education program. Becouse is not much what he teach, is HOW he teach [ realy helps people ]. .
Hello. Mr.Ty. I'm HVAC student and enjoying every videos you have as a matter of fact I watched each at least 4 times to grasp it. Thank you for your time and sharing your knowledge. One question in PSIG if it is equal pressure converted to temperature. I thought we can't measure latent heat except for measuring it through BTU. So how when we look at gauges for psig then for related refrigerant gives us the temperature. So is that the temp of superheat which is sensible or saturation latent heat?
Im an automotive technician of 25 years and one of my colleagues (a specialist in Automotive HVAC) shared this video with me. This is a fantastic video and has cleared up some confusion Ive had for years. Very much appreciate you sir, youre a fantastic instructor!!
What an awesome instructor, we need more people like you in the world. Thank you for posting this, you made this topic super clear and easy to understand! 😎
WOW! With all due respect to the field technicians who have taught me so much via RUclips in the last 8 months, THIS 30 minute video tied so many bits of information together. I can finally see the light!
I started in the field but I kept having questions. Let the curiosity be the drive to learn more. I make it a point to read something new in hvac every day
i took my HVAC lessons in north east institute of industrial technology in 1979 in Boston "it is closed now" , you remind me of the teachers, excellent video you made, i hope to see more.
I just read your post, amazing, my father also went to The Northeast Institute of Industrial Technology in the late 60's to study refrigeration & air conditioning. Then settled in the UK. Nice to read a post from someone who also studied there as well. I'm sure it was a great place to learn refrigeration technology . Take care Amer
Thank you for posting this i finally understand saturation point...and many other things because of your brilliant teaching hope to shake your hand one day!
In refrigeration I have seen a common engineering practice - where / in which your liquid line and your suction line are tied together side by side ( touching / in contact ) with each other . This helps to further subcool the liquid refrigerant entering your TXV - and - at the same time - further superheating the vapor refrigerant returning on the suction side of the compressor which ensures no flood back or liquid slugging your compressor . Great Instruction 👍👍👍
Dude! Watching this actually makes me wish I went to school. Learned all this shit in the field and took me forever grasp. This guy broke it down perfectly in under an hour.
If you had a Patreon account I'd send you money. I'm not even in the AC profession. Perhaps if I watch all of your videos I could be... 50 years old may be a bit late but we never know what tomorrow can bring. Anyway, that has to be the best explanation of saturation, subcooling and superheat ever. Thank you for sharing. Wow!
Mr. Branaman, I’m enjoying your classes so much! You’re very enthusiastic and explanatory. Have made things such as super heat and sub cooling something with so much sense to me. Thank you so much. I understand! Super heated vapor above the saturation temperature. Sub cooled liquid under saturation temperature.
Thanks for uploading this. Everything was broken down well. The interchangeable names for saturation, different examples, multiple angles, illustrations all made a topic not a lot of guys I've met being unable to explain understandable. You rock, dude.
You have a nice beginner course going here, explained in layman's terms with a bit of the scientific mixed in. Good job Sir! You're transitioning them from guys and girls with common sense into a more scientific bunch. We actually give classes at our company for the kids and adults coming out of refrigeration school just as you are teaching here. They don't need to know all the science, but what is relevant and most relevant to a refrigeration system. Don't forget to let those new scholars know that it doesn't matter how cold you're getting something, it is always the same process of moving heat from one place to another. It doesn't matter if you are cooling air, water, glycol, or even another refrigerant, it's the same process. (When I say other refrigerant(s), I'm speaking of cascade refrigeration systems). Good show, good teaching, and good luck to all that are learning the refrigeration process and how thermodynamics work!
excellent teaching. do you have another video explaining when to stop adding refrigerant using superheat and subcooling temperature? i assume this concept applies to refrigeration too and not just hvac units. also for new or empty refrigerant units (hvac or refrigeration), is measuring the superheat and subcooling temperature is the best method to perfectly add refrigerant?
Thanks Ty , just learned what hidden heat/latent heat is, and saturation no change in temp but change in state , you make things very understandable Many thanks..... great videos 🤝
Hello I want to add my comment the beauty of refrigeration depends upon thermal properties refrigerant. For existing refrigeration units all are calculated and designed so only need to troble shoot the breakdowns. For new projects it is very important to learn thermal properties of refrigerant, so easily understand and can play in Refrigeration
Saturation temperature is the temperature at which refrigerant is boiling in the evaporator at the lower pressure. & Saturation temperature is the temperature at which refrigerant is condensing after the de superheating in the condenser at the higher pressure. Do we need to check the pressure after the compressor to ensure saturation in condenser is happening at an some required and expected temperature? Do we need to check the pressure after the expansion valve to ensure saturation in evaporator is happen at some required & expected temperature? Saturation temperature is pressure converted temperature inside the condenser and evaporator. Thanks
Will an overcharge cause superheat to go down to the critical point of 5 or less? What are the standard normal operation ranges for piston metering devices? Normal range for TRX value?
Saturation can be pretty confusing to understand but best understanding is point where both liquid and vapor exist. That changes with temperature and pressure accordingly
Thumbs up I really appreciate that 👍 so absorb latent heat from room temperature than sensible heat above saturation point. At condenser rejects latent heat then sensible heat below saturation. Correct me please if I’m wrong thank you sir
Soon as refrig enters the hi side(After compressor) it begins the heat rejection process. First desuperheating occurs(sensible heat loss) then once it has desuperheated to its saturation point(condensing point) which is where liq n vapor exist together it begins removing latent heat(changing state from vapor to liq) remember the temp doesnt change during this time. Then about 95% on the way down the coil it is liquid and as it travels the rest of the way it will lose sensible heat making it subcool(temp of liquid below condensing/saturation point). U want subcooling for 2 good reasons and the more u subcool the better(generally). Reason 1. To ensure the metering device gets only liquid(cuz that's what its meant to meter) and reason 2. The lower u drop the temp before the refrigerant goes thru the metering device the less flash gas u will have once it enters the lowside. More flash gas is bad in evap cuz the job of evaporator is to evap the liq refrig. If u have a large amount of ur refrig turning to flash gas then u r losing capacity for ur evap to absorb heat cuz it has less liq refrig to vaporize
In regards to mini split heat pump units, if you are meant to use the sub cooling method as a way to check refrigerant charge because of EEV in outdoor unit, how are you able to do it if there is only 1 service port on the Suction line and nothing on the liquid line? a lot of mini split systems seem to have this set up. thanks!
Mr ty branaman I am learning hvac ! English is my second language! My instructor told me saturation meaning liquid n vapor both exist! Yes that’s true! When I ask him said if I open with refrigerant cylinder to atmosphere it still saturated? He said yes! I don’t get it! For I understand meaning if saturation has to be in seal container! Liquid molecules go up become steam molecules, n steam molecules touch liquid come back to it! Rise molecules n come down molecules number equal! It’s call dynamic equilibrium! That’s real meaning for saturation! Even though water n refrigerant is big difference right! But saturation still meaning the same? how refrigerant be saturate with open pot or open Container?Because all molecules will go away with open pot? Could u please help me out n explain it please?

Hands-down, the best explanation I could find online and in books in regards to saturation, superheat, and sub cooling. Bravo!
Funny how the best Superheat Subcool video on RUclips is a guy with a whiteboard and not 30 minutes of flashy animations. THANK YOU!
This is the best explanation of Saturation, Subcooling and Superheat I have seen! Good job!!

amazing great teacher best of the best many blessing.
Great video I love your enthusiasm as a teacher, and this is the only video so far which has allowed me to start grasping these concepts 👍🏼 thankyou
Great way to explain such confusing topic in such a simple way. Thnks

Great video and excellent explanation. I wish i had a teacher like this in my younger years. Thank you!
I wish my lecturer was that enthusiastic.
These guys are lucky they have an instructor who's capable of explaining the material in a way they can understand
Excellent teaching!
After watching so many different youtube you gave me the wider comprehension. About ready to tune my own.
very good lecturer 好棒 from Singapore.

I've always said that the best instructor is the instructor who becomes his own
student when hes teaching.
Saturation means effectively the state of a gas/liquid in between those states? A mixture, of gas and liquid ?
Never a boring moment very good teacher
