Thank you jack for video I'm taking class for EPA AIR CONDITIONING this video help me understanding the class hope you make more video like this for beginners😉
Thanks for trying, I still don't have a clear observable way to understand "heat seeks cold". Air colder than 32 degrees F freezes water. An hot stove may burn me, I don't know how the burner feels, only how I feel. I don't want my finger to touch a hot stove nor a liquified gases. I totally understand different temperatures seeking equilibrium through convection and conduction, and that heat also radiates, and higher heat will produce more radiant heat than cooler heat. I just haven't seen an exercise of "heat seeking cold" that cannot adequately be explained by different temperatures simply seeking equilibrium through convection or conduction or the fact that something is warming up because it is absorbing radiant heat. For the most part, my current understanding hasn't really hindered me from understanding how HVAC carries heat from one place to another, I just haven't seen a great example of "heat seeks cold", hence my post.
I've done more research on this and understand the flow of heat is from hot to cold now. However I still get hung up when people say the CAUSE of heat transfer is BECAUSE "heat seeks cold" in many scenarios. Watch 2:30 to 2:54... He said this transfer of heat from the cold outdoor air to the colder heat pump coil worked "BECAUSE hot goes to cold". Now, does a heat pump really work primarily BECAUSE "heat goes to cold" or is it really working primarily because of convection of air movement causing the outdoor air to flow across the coils and the conduction conduction through the aluminum fins to the copper/aluminum tubing and finally to the refrigerant. In the scenario in the clip I pointed out, it's much easier for me to simple understand that different temperatures want equilibrium and to understand that convection and conduction were vastly more important than the direction heat flows. P.S. your analogy was pretty good.
There is a very distracting noise in this video I don’t know if it’s the audio itself or a throat clearing noise but it makes it difficult to listen to especially with headphones on. I’m sure the information is pertinent but I’m going to have to find another one to watch that noise really takes away from the information being relayed.
Light a match and hold it near the floor by an open door and tell me no cold air comes in. thermodynamics, hot air rushes out the top, and cold air enters through the bottom.
I like the fact that you mention heat moves in "all three ways"... its almost never one method of transfer. That said, even though fluids (say water) heat will circulate in convection currents... isnt a tiny portion radiated within the fluid... ie from a molecule at top of the container radiated through to bottom. Best regards. thx for insight!
this manual J is full of crap. manual j said my home needed a 1.5 ton. the system does not keep up with the home nor am i able adjust my temp throught the day. full of crap that causes your energy bill to skyrocket
It's possible that a Manual D was not done which calculates the necessary duct work needed in your home. Both a Manual J and D need to be done in order to get your AC system working optimally. Of course, it's quite possible the person who did the Manual J did it incorrectly too.
@@OramWerd Would you also explain how CO2 is a bad thing, since without it there would be no photosynthesis, thus plants would die not thrive. Climate change is a real occurrence, happened from day 1 of this planet and will continue till ?. But this man made global warming shit is getting old. It is clearly based on taxation and control.
@@helpmeimconfused Your user name fits you well. My comment was clear for anyone with cognitive skills. Global warming is controlled by the sun and other factors. Man-made global warming is a taxation and control scheme. Must suck to go thru life totally confused, LMAO!
I love how the instructor explains things, he also has a nice tone.
You're a great teacher, easy to listen to and keep it interesting, thanks for posting
Hysterical. I wish you would come here to install my new system.
Thank you jack for video I'm taking class for EPA AIR CONDITIONING this video help me understanding the class hope you make more video like this for beginners😉
Thanks for the information keep they coming I enjoy watching the videos I'm just getting into the HVAC/R this a big help.......
Same here!
Keep the videos coming📝📖👌🏾👌🏾👋🏾👋🏾📚📚 I'm waiting on them 🤔💡🤔💡🤔
Jack Rise is the man...thank you
How or where can I watch the rest of this video... Very easy to understand
Jack Rise, knows his stuff,
Hello. What BTU difference you think In between cooling and heating? Thanks!
The video ends abruptly. Is there assxind) a second part?
What is the most convincing way to prove "heat seeks cold"? I've always had a problem with understanding this.

I enjoyed watching the video...do ou have any more videos available?

Great video though
Global warming is not a liberal vs. conservative issue. It's the best available science.
8-10 grand in 2011, wow. Now you can buy a FLIR infrared attachment for your phone for a couple hundred.

I think Fluke offers the infrared camera.....
nice video I known but I watch it very carefully very nive

someone did not enter correct info
Manuel j is my grandpa
But he died😣😣😣
radiation best example could be microwave oven heating food :)
Al Pacino ? that you?

Lots of talking not much information on calculating.
Whoops...once you went to global warming (c02)...got to take it back..
Do you really think global warming isn't real? Or are you trolling?
@@OramWerd
I don't.....but if you can tell me why you do it might convince me....so please
