I second that! You can thank our 'resident automotive guru' (who by the way doesn't even own a TL or Chrysler 300) HARDRIVIN1LE for all of the useless dribble in this thread.

I am not the party responsible for changing this thread into a discussion on fluid mechanics. Reviewing the history of this thread makes that fact abundantly clear:

On the left side of the cylinder there is a gas under pressure (P1); the pressure is created by pushing on a piston. On the right side there is an area of very low pressure or a vacuum. The two sides of the cylinder are separated by a partition that has a small hole (throttle) in it. As the gas passes through the throttle from the high-pressure side (left side) to the low-pressure side (right side) it expands very rapidly. This is adiabatic expansion...

Everything has an internal energy, even gases. When pressure is applied to a gas its internal energy increases because we are performing work on the gas. As the gas expands its internal energy decreases because the gas is performing work by expanding.

(1) D internal energy (D U) = heat added or removed (dq) + work done to or by the gas.

Since there is no heat added or removed, the first term (dq) = 0. So (1) becomes

(2) D internal energy (D U) = work done by the gas (dw)(ii)

When gas performs work dw is negative so the internal gas decreases. Intuitively since we know that temperature is an indirect measurement of energy, we can guess that the temperature of the gas will decrease as it expands. This decrease in temperature is the Joules -- Thompson effect.
Obviously you don't read your own links because this explains the effect and is completely opposite of what you quoted immediately above. You don't seem to understand you don't need a highly compressed gas escaping through a small opening for this to occur and your previous quote is so not true that I can tell you when it would be wrong. Guess what ignoramus, I will prove your stupid lack of understanding about this statement.

If a highly compressed gas at 145 degrees is expanded through a small hole and cools to 55 degrees, and the surrounding air is at 35 degrees, the expanding gas doesn't cool crap. In fact, the 55 degree gas would be cooled by the surrounding air. So there, the statement taken out of context is not true at all but of course you wouldn't understand that because you quote what you do not understand.

Your above mindless quote is more accurate in that any gas that is allowed to expand will have a decreas in temperature, whether through a TXV or not.

The amount of internal energy given up by the gas (in the form of heat lost) as a result of the Joule-Thompson effect ~ = the amount of mechanical energy that was added to the gas via the compressor.

That amounts to a lot more than "crap."

Exactly right! but this cold refrigerant will not remove heat from the surroundings unless the surroundings are warmer! and that makes your first quote a fallacy. Your are correct that I didn't remember the joules-thompson effect until you found it in your search engine and began quoting it without understanding it. Again, answer this question and don't skip over it!!!

Can you talk about anything without linking something or quoting someone else??? Answer the frickin question!!! Read this again, one more time, can you have any logical thought without quoting someone else or something you don't understand???? Prove me wrong. For the next 2 days you are to respond to all threads on this forum without putting a link in your response or quoting someone else. You simply can't do it because you can't think for yourself. You are an idiot, ha, ha, ha, ha, ha. You are an idiot, ha,ha, ha, ha, ha, ha. You are an idiot...

DUH

Did your 6th grade science teacher just teach you that today?

:lol1:

You mean to say that the COLD refrigerant flowing through the evaporator will absorb the heat (via the copper coils) from the warmer space that's being cooled?

WOW! :cop:

You are so freagin ignorant and again you show your lack of understanding!

This statement is true but if you don't cool the compressed gas prior to expanding it, you don't get refrigeration. So what you said above is that if I compress 50 degree refrigerant to 140 degrees and then release it back to the original pressure, I will get 50 degree refrigerant. So what did that accomplish?????

What YOU accomplished is clearly NOTHING.

It is THE JOULE THOMPSON EFFECT that removes the heat from the freon (or whatever refrigerant is being uses). Obviously the PERFECT GAS LAW plays a roll in that (PV=nRT), but refigerants aren't perfect gases.

Sure it it.

The refigerant is cold because the Joules Thompson Effect MADE IT THAT WAY!

"Next, the high pressure condensed refrigerant (which has rejected its heat to the environment) flows through the Expansion Valve and then into the Evaporator which, again, operates at low pressure.

Got mine from UMASS - graduated with honors, in fact.

It is the JOULE THOMPSON EFFECT that "cools" the refrigerant to a temperature that is lower than that of the space to be cooled.

It's a simple matter of VERY basic heat transfer (via copper tubing) beyond that.

The Joules-thompson effect did not make it that way. The fact that you compressed the gas and then used some type of condenser at a lower temperature than the compressed gas to remove heat from the compressed gas made it that way.

Your above statement conflicts with this statement. The below statement is not true. The escaping gas will not absorb energy from its surroundings unless the surroundings have less energy. This statement is not sure!!!!

The Joule-Thompson Effect

When a highly compressed gas is allowed to escape through a small opening, it absorbs a great deal of energy from its surroundings, causing the surrounding temperature to drop. This is the basis of refrigeration.

Now answer the question I asked you!!!!!

This is not J-T is by your own quote. J-T has nothing to do with the space to be cooled the way you quoted it. If the space is cooler than the expanded gas, then you are saying J-T is not true. J-T merely says that an expanding gas has a decrease in temperature. This has absolutely nothing to do with the heat transfer portion of the refrigeration cycle so again this statement is wrong:

When a highly compressed gas is allowed to escape through a small opening, it absorbs a great deal of energy from its surroundings, causing the surrounding temperature to drop. This is the basis of refrigeration.

This is how your refidgerator or AC works. A compressor (left side of cylinder) pumps a gas (freon) through a throttle and into a network of coils (right side of cylinder) where it rapidly expands and cools.

I think you are full of it and obviously don't have an engineering degree. At least I hope they don't give degrees to some one as ignorant as you.

You're so predictable, how many also knew this would be his response? Puhleaze child, if this is your best you need to put it to rest. It's as lame as all your other diatribes only even more pointless.

I'm just waiting to see when Swat dude will come to his senses and let this go. We all know you won't come to your senses, that would be like asking a crying baby in the middle of a fit to stop crying. So we have to hope that swat comes to his.

Continue on making a mockery of yourself, I'll continue to watch from the bandiwdth and laugh. You're good for that at least if nothing else.

He Googled himself a bride, after he explained to her how he knows more about being a woman than she did and he showed her links to prove it she found the ugliest guy she could find and left with him because anything would be better than one more day with this dufus. Just a guess, but pretty close I bet.

So do think Sadamm lived with a wolf boy before he was discovered? I read that in the enquirer. I think its true. In fact, I think everything on the web is true. Your so called evidence is a joke and the fact that you don't understand it is even more of a joke.

THAT is what "J-T" is saying.

Obviously we need a larger volume to allow the expansion...

But it is the ENERGY ADDED BY THE COMPRESSOR that is effectively lowering the temp of the refrigerant. It is the COMPRESSOR that performs the work in the cycle.

And citing the "constant gas law" in an attempt to explain this cycle is extremely simplistic and not representative of the total energy transfer that is taking place.

THIS is the essence of the refrigeration cycle, whether YOU like it or not:

http://www.hodsonhome.com/mna2001/ch.../adiabatic.htm

"When gas performs work dw is negative so the internal energy of the gas decreases. Intuitively since we know that temperature is an indirect measurement of energy, we can guess that the temperature of the gas will decrease as it expands.

Omigosh!!! That is the most ignorant thing you have said yet! So what your saying is the refrigerant circuit violates the laws of physics and the conservation of energy. Cool. You should build that because you would be a millionare.

So let me get this straight. I add energy to the gas by performing work on it mechanically with a compressor, and then I take it back to its original pressure, and magically I have less energy than I started with.

NO! NO! NO! I must remove energy from the gas via heat transfer via the condenser to have less energy when the gas is allowed to expand back to the pressure I started at. You are a dope and I am done.

THE COMPRESSOR DOES THE WORK IN THE SYSTEM.

ALL OF IT.

This link makes it perfectly clear.

And you don't "take it back to its original pressure" nor have I ever claimed that to be the case. (The gas couldn't expand if the pressure remained the same.)

I think we know quite a bit about him from his behavior here:

1) He has incredible difficulty in social situations. People don't like interacting with him and he has no idea what's wrong with all of them.
2) He has a college education and is intelligent, but not remarkably so. His education is distant enough in the past that he remembers elementary concepts but he is very rusty on things he learned but does not need to apply regularly. But you'll never get him to admit it!
3) He is single and has no significant other. He's never had a long-term relationship and has no close friends; friendship is unable to blossom in the shadow of his controlling and abusive behaviors.
4) He craves being the center of attention in a group composed primarily of late adolescent-to-middle-age males. He doesn't know why.
5) He has an incredibly negative self-image.

All in all pretty sad. He could be a contributor here and a positive member of the community, but he lacks the skills and social graces to make it so. Instead he spews bile and ridicule on others and believes the problem is with everyone else.

And you're dumb.

Your are therefore only able to resort to personal attacks because you are unable to comprehend simply concepts like this one:

Psych major? And you obviously hit the nail on the head considering HD's response.
