It videos like this that would have been so helpful as a beginning tech. Parsing through what various old timers called things was always challenging. The current and next generation techs will benefit greatly. Thank you

22 years in this field and I gain knowledge from every video you make. Still learning! Thanks

I once confused TD with STD. Boy was I relieved after seeing my doctor.

I just started HVAC/R school last January and I stopped confusing these terms when I was told to think of TD as (T)wo (D)ifferent media temperatures (one being the temperature of the air and the other being the temperature of the boiling refrigerant!) ΔT just fell into place after that distinction (the difference in the temperature of the same meda at different points in the system).

I always thought TD meant TouchDown 🏈 and Delta Tea was was a fancy refrigerant. I stand corrected. Thanks for your wisdom Brian! 😅

Great explanation again. No one can hold a newbie airconditioning tech back with content like this in the web. Thank you.

Every day I learn something new here and will hopefully be a little better tech than yesterday. I always just use Delta T but never thought to take TD.

Awesome Sharp explanation😊

Evaporator temperature is called apparatus dew point. Never ever heard of TD before.

Good to know. Never knew to even take TD. I always just used delta T

Well done Bryan. Thanks!

I always learn something I didn't know with your videos i always thought they where the same

Never knew that, always thought it meant the same now i know thanks

Thanks for the explanation, I needed that.

Wow i away thought that it was the same for 25 years. Looooool.

To make things even more confusing, Td in meteorology typically means dewpoint temperature. ΔT does mean temperature difference since Δ typically means difference in scientific formulas.

Nice job and video like always

Ive never used td to describe saturation temp from air temp.

I wish every tech would watch this lol

Is there an hvac company to work for in the area of saint Petersburg florida that is as thorough and cares about the customer and there employees and the desire to do things the right way as you care and teach others? Could be a long shot but maybe at least something close to it.

great video

You got you.

So basically if someone keeps at 68. And it’s not that hot outside, unit can freeze up alot?

AMAZING TIP FROM TY BRANAMAN TO HERE. THANK YOU.

I've always thought that TD was for refrigeration applications only and Delta T was for comfort cooling.

I love your videos .I'm a student at the pbsc and you have pulled me through many difficult concepts to understand. Thank you very but very much. Oh would you take a little observation. Can you speak just a bit slower. This material is sometimes too hard understand and also the amount of examples when explaining something kind of divert the point you are trying to implie.

Just to clarify your saying saturation temperature - S.A.D.B.=DELTA T, R.A.D.B. -S.A.D.B.=TD?

Nice 🙂👍

So as a backward scientist. Add and this subject matter is my game. Delta w.b. plus delta D.B. AXAMPLE equals 30. 12000 ÷30=400. After some 1000 commission's this is what I've observed. So my question to whom I most respect. What do you think. I work at a shop of 200 tech's. I'm sure I've been the only one that received a complaint of to cold. So I up air flow from 350 cfm to 425 cfm. Nice lady let me prove my jargon. Ambient 95 rh 80. Indoor 76db 42 wb. At 425 72 db 54 wb. She was happy. I had the opposing opinion.
