Hey /sci/,
I am having an embarassingly hard time understanding absorption refrigerators. Like quantum physics hard time.
Will someone please explain this diagram to me? I know it shouldn't be so hard but fuck if it isn't.

>> No.3687612

bump for also confuse
this shit doesn't use a pump, it's a type of heat engine

Skip to 43 min, watch the next 5 minutes. It's a rather simple explanation though.

You seem to not know the difference between basic physics, and advanced physics. Let me clarify it for you.

Absorption refrigerators = Basic Thermodyanmics = so easy an engineer can do it

Quantum Mechanics = Possibiliy the most advanced field of physics/science = Requires god teir intellect, impossible for an engineer to comprehend

Thanks for repeating what I said in OP. It didn't help at all.

This is an accurate and detailed description of a condensation refrigerator, which is not an absorption refrigerator. And the guy keeps saying "Ammonier". Thanks though.

I'm an engineer, I had two classes about quantum mechanics, more advanced than what they saw in the Physics program...

Alright, so, in that link, an absorption refrigerator is an illegibly gritty diagram or a condensation refrigerator that uses two pumps instead of one. This makes even LESS sense, especially in the context of the diagram I posted.
Does soeone wanna do what I actually asked for and explain the diagram in the OP?

>> No.3687750

Do you mean an Einstein refrigerator or an absorption refrigerator?

>> No.3687760

An Einstein refrigerator is a type of absorption refrigerator.
Absorption refrigerators are confusing enough in that they are a heat-powered refrigerator, but an einstein refrigerator uses three fluids and does not use a pump - or any moving parts - at all (though if you're going to have a pump you may as well have a condensation refrigerator, so I don't even get the point of that).

Einstein refrigerator, though. As in diagram.

Well you could try looking up Einstein refrigeration cycles and get a professor's explanation along with most likely a better diagram that describes the various elements in better detail than the diagram shown in OP. It looks like they use multiple working gases and liquids to maintain a constant overall pressure, while the partial pressures of the gases change throughout the cycle. The flow is driven by a bubble pump and gravity, and uses butane, ammonia, a water. in the evaporator, butane and ammonia are mixed, giving the butane a low partial pressure. in the condenser, water is present which absorbs the ammonia, giving the butane a high partial pressure.

I'll see what I can find along those lines.
I am amazed at how generally-not-nice /sci/ is, though.

>> No.3687893

>>3687826
You shouldn't be.
I guess I left out a description of one quarter of the cycle but whatever. I liked reading about this refrigeration cycle though, its pretty interesting and I've never heard of it before.
