hey man. this is undoubtedly one of the best TH-cam mech channels if not the best. I've learned so much from you so thank you. the diagrams you have are of great quality and very helpful for comprehension during the presentation. keep it up and if you can reach your shoulder, pat yourself on the back.
Great explanation again on refrigerant ...however i would like to see a detailed process of actually creating them...like a how its made video... they only have one on making containers for them not the actual refrigerents DuPont makes/others make... I imagine its harder then just making air gas that welders uses by a huge compressor and distilling the air process.
I just discovered this channel recently and dare I say its one of the best youtube channel explaining electricity and its related devices. Hope you bring out more awesome videos.
No, the GWP figure is just the refrigerant release itself. This is the whole scam. These low GWP replacements, like CO2, have a poor COP and use 40-60% more energy and therefore 40-60% more carbon. The carbon footprint from the energy usage of a system is several orders of magnitude more than the footprint of the refrigerant should the charge be released into the atmosphere. Unless your power is nuclear/not fossil, we should be using the most efficient refrigerants possible. The industry is run by salesmen.
UV radiation is in no way deflected by ozone, even in this case the UV photon destroys the O3 molecule, but this is by no means as bad as it is with chlorine, in the natural process, it is sufficient that newly formed ozone can rise from the lower atmosphere back into the high atmosphere and fill the gaps
If the buildup of dense green house gases allows more infra-red energy to be reflected back to earth, why doesn't it also reflect more IR energy before it reaches the troposphere?
Good question, I think to some extent it will reduce the amount entering, but it's a constant stream of energy from the sun so for every 1 unit of energy that is deterred, a vastly higher quantity will get through. As it passes through, hits the planet and it reflected back into space the chance of colliding with a greenhouse gas particle doubles, each part that is reflected back to earth will then have to try again and some of that also won't make it. So overall, we still get that build up which outweighs the offset.
It's really about the heat that objects release through infra red. All objects release infra red. A lot off that occurs are night. If we have greenhouse gases that infra red gets reflected back. Also keep in mind that the sun shines more than just infra red and that gets absorbed as heat.
@@EngineeringMindset I'm not sure if this is an adequate explanation - if the gg's in the troposphere are capable of reflecting IR radiation (possibly others too), then why is the assumption that it works more one-way than the other? i.e. if it's really a bit like a double-sided mirror with holes in it, then the IR penetration or reflection will surely be similar and the gg's are really only making the holes in the mirror smaller, which should allow allow more IR reflection from both sides of the troposphere!
I'm trying to build a cooling suit for van lifers so they can save on cooling costs to cool their bodies, and I was looking to use a liquid that could evaporate quickly at a low pressure and at body temperature, which would be cooled via a peltier device and condenser coil.
In a calm stagnant environment, refrigerants will settle or sink because they are heavier than air. But air or the atmosphere as we know is windy, therefore the refrigerants get mixed and lifted into jet streams which carry the refrigerants up into the ozone layer.
The future refrigerant to change refrigerant sintetic is hydrocarbon refrigerant. Hydrocarbon refrigerant familiar with environmental so can decrease consumsion of power electrical
If everything is going to HC does this imply oil companies and natural gas companies can manufacture it simply by there byproducts of refining the fossil fuels... because it seems its all HC going to... Again when it started with CFC it had no HC in it ...so that seems to me it be a completely different manufacturing process then oil refinery byproducts...And need a completely different manufacturing process... curious because i know how recycling process goes it pretty easy but creating it to begin with is difficult for me to understand
Somewhere i remember seeing the last letter in refrigerant types standing for Alternative aka a meaning akternative at the end of ie r134a. meaning Alternative
I always think the greenhouse gas effect, the warm gas is manufactured directly in earth. Now I understand that the heat comes from the Sun, reserved at earth
Can anyone explain how these gases affect the environment exactly? Where are the studies and evidence to support the claims that these gases are doing what they are claiming they are doing?
They cause the ozon hole in the North poles and that is the reason why we have a huge whole in the earth plus its in our text books we study . since chlorine is heavier than air it breaks down the carbon molecules in the stratosphere .since technician have been letting this out thinking bleach desolve in water it didn't it went straight up in he air destroying 100,000 molecules

This video is underrated, such a great explanation. Thank you!

This was hands down the best explanation of GHG and ozone and their effects I have come accross yet.
Thank you man this really helped me with my thermodynamics class
Phenomenal videos that’re attention grabbing with amazing explanations. Thank you!
I just discovered this channel recently and dare I say its one of the best youtube channel explaining electricity and its related devices. Hope you bring out more awesome videos.
Glad that I finally know what an HFC is.
Nice video,can you do one on alignment with dial indicators please.
Who should be retrofitting systems? In what region? Are you talking about specific countries or what?
Just found your videos, and im pleased to be learning things i was on the fence on before, thank you!
hey Paul thanks for sharing valuable knowledge can u plz make a video on chiller installation.

What everyone is overlooking is, the flamible refrigeranrs are mixed with oil, the combination is like napalm if there's a fire under the compressor
Extra ordinary explanation
You spent so long talking about "the environment" that you forgot to talk about the actual performance of the refrigerants
awesome explanation boy
Great videos, but do you know if there are any issues with health? Thanks.
Does not lightening create ozone every time it discharges?
What are the suspected long term effects on living organism as opposed to artificial
Do they take into account their efficiency when calculating their footprint or just the refrigerant in itself
No, the GWP figure is just the refrigerant release itself. This is the whole scam. These low GWP replacements, like CO2, have a poor COP and use 40-60% more energy and therefore 40-60% more carbon.

Thanx alot 👍
What if we mixed alcohol and water to lower the boiling rates and decrease the freezing rates so it's more suitable as a refrigerant

Do the refrigerant 136 exist?
My teacher told me to investigate its properties but I do not find it anywhere
No, two carbon atoms can’t be single-bonded to each other as well as six fluorine atoms AND two hydrogen atoms.

Would you be able to explain how refrigerant is heavier than air.. but also climbs to the ozone? Seems like a contradiction to me.
In a calm stagnant environment, refrigerants will settle or sink because they are heavier than air. But air or the atmosphere as we know is windy, therefore the refrigerants get mixed and lifted into jet streams which carry the refrigerants up into the ozone layer.

i dont understand why this video has so few views

The “a” in R-134a means it’s an isomer of R-134, they have the same chemical formula, but a different arrangement of the atoms.
Super

Why not use liquid Nitrogen?
It requires extremely high pressure, new systems would have to be designed specifically for it.

I thought this was a video on refrigerant types. It turned into a global warming video around 6m in lol.
The reason that refrigerants are changing is to lower their ozone depletion potential and global warming potential.
Yeah, he didn't mention _anything_ about their performance
