New Refrigerants Codes and Standards

Are you prepared for the new refrigerants that are being phased in, while R-410A and other refrigerants are being phased out? Check new refrigerants, codes and standards.
What existing R22 & R410A refrigerant tools can you use with the new refrigerants?
Can you replace an R22 or R410A Outdoor section with one of the new refrigerants or do you also need to replace the coil and piping? What refrigerant will Daikin or Trane be using in their unitary equipment? Is this Refrigerant currently in use around the world? ASHRAE 15.2P will apply to Residential Properties

Good video ...... Just more freon B.S. we don't need in the hvacR industry .... good day

[@MEPAcademy]

We must adapt to the changes that are being made for the good of humanity. If existing refrigerants are harming the environment then why not keeping looking for better solutions. Each generation builds on the previous one to keep evolving to make life better for the generations yet to come.

[@taiwanluthiers]

@@MEPAcademy My issue is people throwing out perfectly good systems to use "better" refrigerant. R22 is plenty good, and I agree that newer refrigerant that is better for the environment should be used on new equipment, but throwing out perfectly good R22 systems just to update them is not environmentally sound. I feel there's a huge amount of planned obsolescence in the HVACR industry, except these kind of planned obsolescence is being forced by the rule of law. I do however question how much ODP matter because most refrigerant we use is heavier than air, except ammonia, so I don't think ODP matters as much. Keep in mind even R12 has a fairly short atmospheric life, so even with fairly high GWP it's not THAT bad. I don't think you can get any better than Ammonia though has it has no GWP or ODP, and it has a 1 year atmospheric lifespan, but the stuff is incredibly flammable, explosive, and toxic, and catastrophic leaks do kill people. However a small leak would get immediate response because it STINKS to high heaven, whereas a CFC/HCFC/HFC leak could go undetected for years because it doesn't really smell. Ammonia is only currently used for very large systems. I think hydrocarbon refrigerants is good except it's extremely flammable... which is not good. It's why they're only used for very small systems.

[@keatonz]

"R-32 is lighter than air, so will seek to settle lower in the room." I think you meant to say that R-32 is "heavier" than air.

[@MEPAcademy]

You're right. A little slip of the tongue, as the image clearly shows the refrigerant settling along the ground. Thanks for the observation.

[@BYENZER]

@@MEPAcademy PLEASE EDIT THE VIDEO WITH ON-SCREEN CAPTIONS, CORRECTING THIS.

[@BYENZER]

THANK YOU! I got thrown into a false understanding of R32 being "lighter than air". Without your comment, I probably would have spewed this falsehood around to my fellow HVAC compadre's. Again, thank YOU!

[@taiwanluthiers]

R32 is already in common use in Taiwan.

[@hamadi0051]

Good information.thanks

[@MEPAcademy]

Welcome

[@dknowles60]

why should i use r 32 that can catch on fire i will stay with r410

[@MEPAcademy]

It's not that you want to switch away from R410, but that in the near future you won't be able to buy it. It is one of the refrigerants targeted to be eliminated because of its high global Warming potential of 2,088, while R32 has a GWP of 675. If you live in California, a state that is heavily involved in moving forward the green agenda, this date will even come sooner, as they are capping the allowable GWP at a level below R410A. Eventually, like our old friend R22, it may become very expensive to get, and prohibited in the manufacturing of new equipment.

[@taiwanluthiers]

@@MEPAcademy I hate to say this but China doesn't care about the Montreal Protocol. They are still manufacturing R22 and R410A. So America can eliminate those refrigerants but China will continue releasing them at will. By the way R410A is already R32 so perhaps existing R410A equipment can simply be retrofitted to R32...

[@BYENZER]

At 08:25 mm:ss, regarding the two different oils, mixing together and creating a sludge: According to Brian Orr, this is NOT TRUE.

[@taiwanluthiers]

I'm not sure how much oil ends up in the manifold, but if it's only refrigerant vapors, it shouldn't be much. The only concern is that POE oil is hygroscopic and that does turn into a sludge if it absorbs sufficient moisture, which is why you had to evacuate the system to microns. I heard there are talks of using CO2 as refrigerants but their operating pressure makes R410A/R32 look small. CO2 has no flammability (it puts out fires, unless it's a metal fire), and a GWP of 1.

[@MrAever]

large house and a basement equals boom

[@MEPAcademy]

This shouldn't happen with the low flammability rating and a properly engineered system.

[@jeremybroderick9465]

r22 is better than anything they come up with way better cooling efficiency

[@MEPAcademy]

Yeah, but since the manufacturing of new R22 has been banned, and all manufacturers are moving away from its use, we are forced to move onto the latest, more environmentally friendly versions.

[@manilaairconexperts1455]

the chinese do not stop manufacturing R-22 until today...

[@MEPAcademy]

Yeah, not all countries participate in protecting the environment.

[@andrewnmanyawu]

It's a such a stupid idea to use such a flammable refrigerant on ac unit because if the build catches Fire that refrigerant will be a good fuel for the fire

[@MEPAcademy]

The flammability of the new refrigerants will be low enough to be safe.

[@MrAever]

any opportunity for a democrat to blow up a house their in lol

[@MEPAcademy]

This shouldn't happen with the low flammability rating and a properly engineered system.
