Great video! I wish the temperature for each line is placed there, so we can picture the heat exchange clearer. Thank you.

[MuzzaNZ]

congratulations on being the first vid on absorption chillers that I could actually understand. Well done TEM!

[ptoktedia]

This is by far the ONLY one i can understand. Thank you so much for explaining the basics. I've stuck in how water refrigerant (of the chiller) creates the cooling effect. The only missing part was vacuum and water boiling point's correlation, you explained that and saved my day almost instantly.

[kierrantrpr]

hey, the chilled water flow direction icon seems reversed.. and I think it will be easier to understand if you put Operating Pressure and Temperature (or T & P for each flow) so we know whether the heat transfers are feasible.. Thank you anyway for making such a great educational video..

Absorbtion chillers are pretty amazing machines frankly, such a genius way to do it.

[hmandeelful]

That was the best explanation for an absorption chiller that I have ever come across, awesome job and thank you ..

[HuntersHavenWithChad]

The energy plant I work in has 2 absorption chillers and the water supply is off our main condensate return line. Pretty cool how it all works and ties together. Thank you for the videos!

[rockanrollrudy]

Thank you this is a great way to learn and your videos have helped me and my coworkers a lot. Thanks again

[dylanwalker]

Thanks for the excellent video! This particular one could definitely have benefited from the narrator pointing at what he was talking about with a cursor or something, especially towards the end when he's putting it all together, it got hard to follow. But still it's way better than the black and white pictures in my text books!

Great video on how this system works. I never understood it until now.

[Magicus]

Wow! That was a ton! I’m kind of upset I never learned this in my HVAC elective.

Thanks for your help!

This really helped shed some light on this topic.

You’ve gained a subscriber!

[spludgey]

Awesome, thanks mate!
I couldn't get my head around it from just looking at the diagram.

[mostafafallahnejad]

Thank you for this video. I'd suggest to add inlet and outlet temperatures of all loops to the graphic that is shown in the video.

[byronjones]

Mate your amazing I am going to get my staff to watch your videos.

[TheBozodclown]

I liked this video a lot, it helped explain things in an accessible way.

Just curious if you can clarify two questions I have:
The chilled water line comes in at about 12°c that's already quite cold. How does it get down to 12 if the area being cooled is hot, say 35°?
2. How does the cooling tower work? Is it just a pipe that the warm water runs through to reach ambient temperature? Doesn't that contribute to heating the area?

[ciaocarbon]

Great explanation, a real human voice and no distracting muzak in the background.
There is no compressor, but compared to a classic vapor-compression A/C, how much energy does the pumps and control system use? This assuming the heat source is "free", just the system itself. Thank you.

[RoBD]

Amazing work! The explanation is so detailed and simplified!

[NewDestinationEng]

so easy yet so complex! great explanation

[VinOng-erks]

The secret lies with partial pressure. As the Li-Br absorbs H2O molecules, it decreases the partial pressure of water inside the evaporator which causes the partial vacuum and hence the cooling effect. This is almost similar to the expansion valves of a vapor-compression systems.
