Yes, I am rewatching this again You blend the engineering and the mechanical perfectly for techs. Whenever I stumble with a HVAC question, I go back to your videos. This reminds me of chess and you break it down as it it were checkers, knowing we need to start somewhere. Thank you again. Raphael NYC
You are by far the best teacher I have listened too. I came looking for some refresher courses before summer and I came across this amazing video. Amazing job
This information is very well communicated. That being said, it is very painful for the smarter/more informed crowd. Beating a dead horse comes to mind. I got the point 10 minutes ago
I just made a giant display board to teach this with. I hot glued onto it a bike pump, a bunch of clear tubes, and one of those spray bottles for cleaning electronics that have liquid inside, they spray out gas, and they get really cold when you spray them.
Hey Ty this has literally all clicked to me after watching this video thank you so much you make it so fun learning about HVACR! We are getting slow in the company I am dedicating the slow time towards your videos and other great HVACR youtubers as well KEEP UP THE GREAT WORK!
thanks for the encouragement! Check out my frends Bryan Orr with HVAC school, he alos has a podcast that's great while driving. Chris with HVACR Videos with live troubleshooting and the big picture diagnostics for commercial. Craig with AC Service tech LLC, by HVAC brother who also has a great book.
Hi Ty - Thanks for another excellent video. One thing that might be helpful to mention (and which I think you’ve done in other videos) is that if systems came equipped with thermocouples attached to the evaporator and condenser cores (near the middle), one could get direct measurements of saturation temperatures in the two coils but since most units don’t have such sensors we must use an indirect method to estimate the saturation temps (I.e., the known relationship between pressure and saturation temp). - Cheers - Jim
if the evaporator/condenser coils were accessible would it be possible to get the saturation temperature using an IR thermometer instead of reading pressure to get temp?
Not with infrared for that purpose because of the reflectiveness of the coil. Get the temperature just past the distributor and that should be the same as saturation. Some minor discrepancy dut to pressure drop. It's a little more difficult with the condensor because of piping variations from the manufacturer, but in you could find the middle of a circuit, it should liquid saturation.
Just a random question. Isn’t some of the heat rejected or absorbed sensible.? Because when the condenser is rejecting heat I can feel it out the top. Which would be sensible right.?
Great question! YES! stay tuned and I will be covering that very soon. I'm going to drive home saturation first, then we will add what you are inquiring about because it is very important also.
Thank you so much Mr Ty. For putting the video together since I asked the question about pressure and saturation relationships. I appreciate it. Also now this is another question On transformer 24v ac. If it is Ac and Ac as we know is alternative power 60 times per second change direction. Why when I put my lead from common to like frame I see 0. I know from Red is 24 which actually I see 28 volts but that is not a question. It is 24 volts Ac not DC that we have positive and negative. I can't get my heads around it. It is funny I passed my esco electrical with highest score and can put traditional ac system with just old relays how used to be together but can't find answers for this simple question. Appreciate it any input. Appreciate it 🙏💯
You are correct that secondary will also be Alternating current. The secondary wires are a completely new source voltage. One secondary wire to the other will be 24v (approximate and 28 unloaded). I believe your challenge is from one grounded side of the secondary. I don't like to ground one side but some people and manufacturers do. Let's start here, we know one secondary wire to the other secondary wire is approx 24v and positibe egative changes direction 60 times per second. Let's say 1 wire is red and the other is blue and I add a wire from the blue to the ground. (Also assuming the building is properly built with proper rounds and neutrals) From any side, the red wire is connected and the other to the ground you will show 24V If you check from anywhere that the blue is connected you will now show 0 because it is essentially the same side, the same wire. Everything metal copper or steel will be the same side. It's still alternating but your meter is not showing any potential deffersnce.
@@love2hvac Thanks for quick response. Teachers like you inspiring us. 2 years ago I was tech school student and within 1 year and half I dragged myself so much up. I started at $16 and now at $22. Yesterday I got challenging job. 2 companies quoted poor old lady new system since was short in her system when it comes on. She called us and my Boss sent me since I'm Nerdy I guess and don't give up. I ohmed compressor but luckily was good. Opened the condenser lid. Rat chewed up crankcase heater. $25 part and 2 hours labor. She tipped me $200 tears in her eye and said to me your persistence and not listening to other companies Bs and more important honesty get me wherever I want to go. Story like this for Yesterday call and watching every possible videos from people you awesome Teachers is huge inspiration for us again. God bless you with all strength. We love you man. Keep it up Mr Ty. Thanks again!
@@1971omi AWSOME! We need more people like you. I also always took care of the elderly. I appreciate your support. This is the motivation I need. Thanks you.
That's correct. When condensation is happening, the temperature is below it's dew point (saturation) so the moisture changes state from a vapor to a liquid. Giving up latent heat.
its funny. imagine. When you put tank into freezer to -30*C chamber, it is -30*C/0,5 bar r134a is 100% liquid, in +55*C/14bar is still 100% liquid when leaving condenser.
Ty really good video, very precise on the subject!,hope you post more!!!🔥🦸♂️🎯on procedures of hvac ,and scenarios, troubleshooting!!! You are one of the best hvac teachers!!!
At time 4:38 you spew the words “half and half”, really fast as if that explains it all. What exactly do you mean by this? Surly you aren’t purposefully trying to be cleverly fast with the BS? You do have the knowledge I assume? Now practice on being more articulate in delivering it.
Ty… why are you speaking so fast that you are stumbling over your words. That is not necessary, and is very distracting to more adept students. Speak slowly, distinctly and succinctly. Speaking slowly is the mark of intellectual understanding. The student needs to understand this or back up and learn to understand this before they move forward in training. Too many ignorant, sub-standard intellect trade involved individuals out there. Grammar skills are necessary for good communication. Anything else is closer to caveman, grunts and farts communication level. please consider this as good feedback. It is meant to be. Best wishes.
His speech is excellent. I do not believe your sarcastic critique was called for. Any American who speaks In a manner which does not reveal his location of origin is considered to be very well spoken. I have never detected any grammatical errors, either. How do you think the blue collar tradesmen he is speaking to would react to the speech of William F. Buckley? I doubt they would understand it.

I understand you very well, You're a great instructor! I know more than my supervisor from watching your videos. Lol....
Thank you! I'm glad your learning, keep on that path and keep moving forward!
I love this one, helps me a lot . Especially the first few minutes, really Impress knowledge into my mind
You kind of touched on it at the end of the video, so never mind sort of. Lol thanks for the videos Ty.! Look forward to more
Ty thanks. For that very. Important. Information much. Much. Appointment

Excellent video! Thank you so much Mr Branaman.🙂
Great video on an overlooked subject
Thank you!
Thanks Sir. It really helps me to fully understand what saturation is. I will re-watch it

I think I’m at 20 times watching this video lol
bravo
Thank u Sir
Awesome!!!!!!!!!! Thank you so much!!!!
Refrigerant, saturated, can be used as a accuracy marker for any devices that are designed to measure temperature.
if the evaporator/condenser coils were accessible would it be possible to get the saturation temperature using an IR thermometer instead of reading pressure to get temp?
Not with infrared for that purpose because of the reflectiveness of the coil.

Aprociate
Do i check the enropy chart to know my suction line refrigerant is now full vapor now? I heard if is not full vapor is going to damage the compressor
Use superheat to ensure no liquid gets to the compressor.
Liquid will damage the compressor.
@love2hvac any video on that? Like how do I know the current superheat is full now vapor? In such case where I might have a stuck open txv
Thank you so much Mr Ty. For putting the video together since I asked the question about pressure and saturation relationships. I appreciate it.

What does "pressure converted temperature " mean?
Temperature pressure chart or PT app. It converts the pressure to a saturated temperature. Examples in previous videos.
@@love2hvac
Which videos?
Easiest way is the Playlist
learn HVAC
They are in sequential order
HVAC 001
HVAC 002
HVAC 003
And so on
So dew point temp is actually saturation?
That's correct.
When condensation is happening, the temperature is below it's dew point (saturation) so the moisture changes state from a vapor to a liquid. Giving up latent heat.
its funny. imagine. When you put tank into freezer to -30*C chamber, it is -30*C/0,5 bar r134a is 100% liquid, in +55*C/14bar is still 100% liquid when leaving condenser.
TERMINOLOGY.
You can't just call EVERYTHING saturation it's confusing!! 😭😭😭

I am a flawed human. This is talking slow, I talk faster in person. I never claimed to be an intellectual,
Sorry to disappoint.
This is a terrible comment, Ty does a great job explaining stuff
