- Excerpt from disc 2 of "Understanding HVAC for Non-Technical People", a special training package taught by Jack Rise and available from ACCA at www.acca.org/store#/productDe... . Provides a basic understanding of HVAC systems for non-technical people who would like to know more about how central heating and cooling systems work. Ideal for HVAC business employees such as dispatchers, salespeople, customer service, and other office staff.

Thank you for taking the time to make.this video. Very informative!
Well explained! Thanks for taking the time for this tutorial. 👍🇨🇦
Great voice for teaching. You actually kept me awake and interested.
Interesting, I have wondered about this rating. And, very clearly explained, thank you !
a great reminder about refrigeration principles thanks dude...
Thanks for doing this. Great video and very informative!
Good information for HVACR red seal exam
Great videos for people interested in learning about HVAC
This video was fire 🔥 and stopped as it was just getting good.
So great...I wish there were more!
Fantastic demonstration & illustration of the physics of a refrigeration. :)
its a very nice lecture about HVAC. Thanks alot
Well done friend,
Very good information bro looking forward to hear from you
Such bold information, where is the second part to this..?
good question,glove 8888. Ice begins to melt at 32 degrees. Air or water temperature measured at the melting point of ice is always 32 degrees. Even if you use a torch to melt the ice, it will melt at 32 degrees.
Very informative, but correct term is latent heat of fusion when a substance go from solid to liquid our vice a versa.
Freaking good Thanks a lot God Bless you...
Thanks for the education
I'm currently in the HVAC class, and I'm finding it difficult to keep up and confusing, but I like the way you explain things.
I am too, did you pass? If so, how did you eventually catch on?
@@merseyside2011 yes I passed, I got a job shortly after and immersed myself in the business by asking annoying questions of my senior people around me.
Ahhh man, where is a part two? Have to say the beginning was to technical for my taste but then the video got really interesting and easier to follow when you got into the place of talking not such much about numbers but about the simple understanding of how the AC system works together with the inside and outside units. But then the video stops suddenly. What happened to rest of the video. No ending to this?
I agree
Thank you kindly
Perfect Video
Thanks for this video
nice job!
Good idea.
I learned alot! can you make another video?
Instead of 2 matches did you mean 1/2 of a match for a 1 degree temperature change over the 2lbs in the phone booth?
Simple tips, easy to understand even for a non-technical user. #hvac
why do the videos keep cutting off at the end
Type of gassage ac diffection siplm writing
why would ice melt at 32 degrees? isnt that freezing temperature
Good job,thanks.
Think pressure. The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. ... This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.
Boyle's law states that pressure (P) and volume (V) are inversely proportional. Charles' law states that volume (V) and temperature (T) are directly proportional. Gay-Lussac's law states that pressure (P) and temperature (T) are directly proportional.
informative (y) thanks
A ton of ice is 1000kg which roughly equal 2200 lb. so the right number is 144btu*2200= 316800 btu.
There's a metric ton and some other ton too right?
One ton 1000kg Convert pound 2000 lb. so one pound require latent heat 144 BTU *2000lb =288000 btu 1 day
Way too technical for me. I need something like,"motor starts XXX and that starts YYY, and when ZZZ occurs, then XXX stops for a while". Or something like that.
yea cool video.
1cubice feet air weight .0741 how do solved
The density (or specific weight in this case) of air is 0.0741 pounds per cubic foot, therefore, one cubic foot of air weighs 0.0741 pounds. Put another way: 0.0741 lb/ft^3 x 1 ft^3 = 0.0741 lb since the ft^3 units will cancel out.
When are you guys going to go metric
Cool video. (See what I did there?)
Ragefeast95 😂
interesting video but wheres the rest of it... i was well into it.. :(
I think this is great, but still over the head of non-technical.
Thanks deer
that's btu/h not btuh
nice video. 1 ton is 2200 lbs though, not 2000 :)
*****
In the UK that is :-P
The american short ton is 2000 lbs, the metric tonne is about 2204 lbs and the imperial long ton is 2240lbs.
Oh kitu ningan krek apal
VVVV lol
Subject: "Don't get it! First thing you do it tell us a lie but don't explain why! 1 Ton = 2240 lbs not 2000 lbs and if you don't know that, what good is this video? Not worth watching IMO."
ACCA - Difference between US Ton and British Ton The British ton is the long ton, which is 2240 pounds, and the U.S. ton is the short ton which is 2000 pounds.
Well it's not a ton then is it! So why call it a ton when it isn't one ? If you want to go around changing already accepted terminology meanings then you confuse everyone who already possesses that accepted knowledge. If you want to use a mass of 2000 lbs that's fine, but give it a new name like TONr or TONac or similar then everyone knows what's going on. I'm sorry to be so pedantic but I find it's best to get it right. Mind you I should have known it was American because of your penchant for changing everything. While you're at it, you might fix your gallons too ;-)
