Introduction to R32 Refrigerant

[@kg4muc]

Good information! I’m not too happy about using flammable refrigerants whether they be on home appliances or residential HVAC. One thing I know for sure is those linear compressors used on home appliances. My new freezer with R600 give up the ghost about 3 months after I bought it and GE said it was not repairable and finally refunded some of my money. Can’t say if it was the refrigerant or the compressor but after discharging and evacuating I manned up and brazed in some taps and the compressor was equalized. Go figure😊

[@johnrehwinkel7241]

All common refrigerants are flammable (R3/ammonia is one exception). However, the hydrocarbon ones don't produce poison gas when they burn like the freon ones.

[@JesseDoesHVAC]

Been here in Australia for over 5 years No issues for us. Every manufacturer coming into the country is basically r32 now, just buy a suitable pump and guages. Reclaim cylinders are slightly higher pressure ratings. It mosty just affected how to transport and store in large quantities

[@realSamAndrew]

Don't forget 410a is simply R32 plus R125 in a 50/50 blend.

[@joez.2794]

Uh, how come we haven't just been using R32 all along?

[@realSamAndrew]

@@joez.2794 because they freaked out about mild flammability, even though it's been used overseas for decades.

Don’t forget R600 is just purified Butane. Imagine how cheap it would be.

[@keepnitkool9042]

I work on a1-a3, but in residential I’m concerned for the customers but more so the green horns who get thrown in it working with an A2L for obvious reasons. But if I had a choice between the two, it would be R32 for the same reasons you mentioned in your video. Good job

Thank you.

Can you get R32 from your supplier?

Thank you for the breakdown of the refrigerants. As a Comfort Advisor, I am getting more questions from homeowners asking for the major differences between r22, r410a, r454b and r32. These videos help me sound more knowledgeable.

[@HVACShopTalk]

Thank you ,make sure to let me know if you need anything else covered in these videos

[@aarontracy5160]

Thank you for the reply. Another topic I am encountering more frequently is the side discharge condensers. Coleman and Carrier are showing up in Phoenix in this configuration. I saw some of your content on the Gree Flex which was helpful. The Lennox distribution center had one on display. Any addional content on the performance and viability of this versus the traditional condenser would be very helpful. Again, thank you for the amazing content and presentation.

[@WhowereEpsteinsclients]

R32 refrigerant and Units are not even available yet in my area. I want to start selling R32 units now rather than keep selling the 410 units that will be phased out by some bureaucrat. Seems like another way to sell “a2l compliant” tools that “have” to be on the truck.

[@mdawaghreh2]

Thank you

[@williamvaughan1218]

We used to care about recycling. Single component refrigerants are much easier to reuse thus preventing contamination of the atmosphere and saving energy and resources. We all know what happens to the majority of fractionated refrigerants...

[@HVACShopTalk]

That’s a good point and common sense!

[@markbeiser]

I've not seen the cost of the 454b yet, but since it has 1234yf in it, I'm guessing it will be pricey. R-32 isn't too expensive.

[@marconantel7735]

So..I was talking to a rep today ( won’t name him) about where their equipment was going; lots of politics are involved in the next gen gases ( with so much money involved who saw that coming right?). Anyway, a statement was made that they are effectively interchangeable. According to the Danfoss slider app there is approximately a 20 Psig difference at 40 degrees. Close I guess, but close enough to be interchangeable? I’m not experienced enough to say.. what are your thoughts?

[@leviyoomoill7085]

Great video appreciate it

[@shanebrooks2013]

Including p/t charts in these two videos would have probably been the first things to include in them…

[@donaldstrader7241]

At around 3:30 you express your preference for single component, which makes sense. I think you are alluding, but don't actually state, that it would make it easy to "top off" a charge if there is a slow leak that is hard to detect, without having to worry if the mix has been compromised. Is that one of the reasons? I'm just trying to learn as a homeowner who needs to replace a old unit (inside/outside) that has finally gone below the amount of charge needed to provide cooling.

[@tairdudeusa7981]

Here we are with 10 months left to go and we don't even know what threads we're using on our hoses. Even though I have had the Esco training the EPA has not even said if certification is required. Maybe they'll let us know what we need to do somewhere around 1/1/25. Perhaps some of the supply houses in the local Atlanta area will have some things in them such as R32, reclaim canisters, hoses if needed. You know all the expensive stuff we're going to have to purchase before we can do this, it's not even available at this point. I know I'm going to need some expensive items such as a fire extinguisher and a holding bracket for an upright reclaim tank (not available in the continental US). Simply put there are way too many questions that are unanswered with only 10 months to go. Someone better get on the ball because I'm not going to be ready if this is the way it's going to go.

[@dporrasxtremeLS3]

Yes, because 410a is to be phased out, soon.

[@jmead6121]

Thanks ...... so can R 32 be charged as an Gas like R 22 or does it have to be liquid charge only ??

[@bills6946]

R32 has a higher discharge temperature. That will result with machines running longer/ cycling more often and potentially unhappy customers. Seems, any reduced energy use in the machine will be lost by running longer or more often. It doesn’t matter. We cant fight the EPA.

[@dave4882]

higher than what?

[@ovfd15]

Which one will cool better. How much do they cost?

[@takkkaros7]

can we put r32 at the systems either liquid or vapour with no problem... ? is like r134a ?

[@neilafram663]

An important point was missed. The GWP effect is when there is a LEAK! not while it's in the system. When & IF it leaks when there is a fire, it will propagate the fire!!! Also, very important flammable A2L (R32 or R454B) might and could INTERNALY explode. This is true if the vacuum process (must be higher than R410A an A1 class non-flammable, non-explosive class) is not perfect (presence of moisture/oxygen) as when compressed the temperature could reach the lubricating OIL ignition temperature, and in the presence of flammable refrigerant (any A2, A2L or worse A3) the oil might ignite the flammable refrigerants! This possibility will not exist if A1 class non-flammable refrigerants are present. Neil Afram Director of Space Air Ltd. distributor of AC & Heat Pumps since 1980.

[@brianhunley5302]

But you have to use more of r54b than r32. So does that make the gwp the same or closer or are the scales tipped in r32s favor?

[@marconantel7735]

Great question! My admittedly feeble thoughts are if it takes more it may be less finicky/critical in terms of charging? IE less likely for someone to blow past proper charge to overcharge? I’m new so may be way off base

[@smacleod69]

The GWP is a waste of time. We as technicians will need to know if the Evaporator coils are going to leak within a few years due to manufacture pathetic design to break down

[@stevee7774]

You can count on this junk leaking like a sieve after a few years. The manufacturers obviously don’t give a crap.

[@curtispilcher6080]

Gwp is one side of it. While r32 may have a lower gwp than 410a there are other environmental factors that aren't being accounted for. The switch from 22 to 410 was over ozone depletion. Honestly it's all artificially manufactured. All refrigerent is bad in one way or another.

I've been wondering if we're going to need to buy all new equipment (gauges, reclaimers, etc.) Both 454B and R32 are more flammable, so how is that going to impact the trade as well? I'm fairly new in the field, but all the old timers I work with are super pissed about the upcoming refrigerant change. I can understand both sides, I'm mostly concerned about having to replace/update all the equipment I purchased only a couple years ago to accommodate these new refrigerants. I searched and noticed there weren't any gauges with 454b's PT on there. When I was at a class at carrier I asked about the operating pressures of 454b and they couldn't answer, so still a lot to learn about these

@@markbeiser Regardless the whole refrigerant situation serves as one of many ways the global elite are trying to lower the standard of living of the middle class. In 10 years they’ll find some reason to outlaw this also. They’ll raise the price and make repairs uneconomical so you’ll have to buy new more expensive equipment. If you buy into this environmental nonsense, isn’t the unnecessary and excessive dumping of otherwise useable equipment into landfills just a different form of polluting the environment? I’ve seen on websites like Ali buba where you can buy a pallet of 30lb cylinders of R-12 for about $50 per cylinder from China. Same for R-22. I’d guess someone somewhere is buying it. Guess it’s only harming the environment if used in the USA and the countries who’s politicians profit from all this nonsense.

[@NeilAfram-lo5qp]

Daikin info regarding the R32 website is deceptive for a simple reason: The only classification for refrigerants are ASHRAE34 & ISO817 and it classifies refrigerant not only in respect to GWP (only important IF it LEAKS). R32 require extensive safety requirements and the 1st flammable (and can be explosive if no perfect vacuum, and called Diesel Effect) refrigerant in splits systems knowing very well that R410A an A1 class nonflammable, nonexplosive is 50% R32 and 50% R125!! and been around since 1990? The only reason for the mixture is to curtail the flammability of R32? it si not more efficient than R410A and by the way you can drop R410A in and R32 charged equipment without any consequence as the main 4 components (compressor, condenser, expansion device & evaporator) ar the same!!! So why use R32 or any A2L in domestic and small splits applications? a con, Ignorance or what?
