Forgot to thank Bryant for all the knowledge his made available to all, just hope one day once I become successful in this field I can pay it forward. Thank you again Bryant, you are changing peoples lives.

Thanks, man! We just started getting the work on the kitchen/cafe small equipment with R-290. At the hospital, we mostly work on the larger systems (hydronic, chillers, walk-in coolers, air handlers, etc...) so this was some new toys and new processes to learn. We were wheeling it outside to vent it, but I love the idea of pulling down a recovery bottle and hose with a valve.

Why don't you use old units that you replace on change outs brother. Im in ohio I like your videos. I've been doing this line of work for about 10 years now and I still learn from tour channel. Keep up the good work

I’ve been doing this for months because of the limited lab time and the need to understand things. Started with one unit that I was lucky enough to get at offer up. I’m now working on my 4th kit using 2 LG units that I was lucky enough to purchase once again in offer up. This is extremely helpful the only thing I’m having problems with is that u can’t measure static pressure because there’s no duct system. That maybe my next project adding a duct....

Bryan, Hello,nice class, yes I do know about the impending 410A TO R32, never knew window units already came with it ,I have been working with R290 for many years, here is a great one for you there IS a METHANE RECOVERY plant on the ARTHUR KILL GARBIGE DUMP in STATEN ISLAND, NYC, the company wanted to use R290, for the refrigerant , but the CITY FATHERS said NO, too flammable , hey we are recovering methane also flammable, So they regrouped & used R22, , 2 DB 500HP SCRER COMPRESSORS , 28,000LBS OF IT So they pump out the methane condense it then de humidify , then send it into BROOKLYN UNION GAS CO , the place SMELLS , all safety stuff, but you can NEVER GET a full flow chart, ONLY what you need to be working on , you also Can only do your work directing dummy OPERATING ENGINEERS , why are you doing so & so ? Just do it , they have zero clues , of what is happening , is has run in the BLACK, for some time now AIR PRODUCTS built it & owns it I last worked on that one in 1992, They also had 2 smaller ones in NJ CHEERS 🇺🇸🇺🇸🇺🇸🇺🇸

What an excellent class! I see some students have a sense of humor lol. Yes, R32 is better. In addition to a lower GWP rating.. it keeps it's efficiency. Like with R22 and R410A in a unit from 2007 with a 10-12 SEER rating, nowadays that's 8-9.

Bert was correct in saying, “there is no such thing as a vacuum”. One of the KZbin channels did a video on it a few weeks ago. For what we do tho there is such a thing.

Forgot regulations. It used to be, flammable refrigerants along with toxic are not to be used in homes for safety reasons. Ammonia is used in commercial ice making. Propane is used commercially. The key is it is not to be used where people live and sleep. It appears the regulations have changed as R32 is listed as suitable for residential buildings and air source heat pumps.
@coldfinger459sub03 жыл бұрын
Not only vacuum let’s say your 50 pound recovery tank but also throw it inside a freezer for ice cream at -22°F. As the refrigerant enters the tank and tries to flash off and equalize with the ambient temperature of the tank the extra low temperature of the tank itself will keep the pressure of the refrigerant very low. Engage the condenser fan and evaporator fan at the same time to keep the warmer ambient air flowing over the coils so their temperature does not drop to help the refrigerant flash off faster. Physics works wonders

14:20 Brazing on an access port to process stub after crimping it. Perhaps its better and safer to install a temporary access port or an access tool, to recover refrigerant then while purging nitrogen, braze the fitting, and the hole made by temporary fitting / or tool.
@dennisnoone74273 жыл бұрын
running a vacuum pump a bit and then purge with nitrogen is a good practice before unbrazing/brazing

The new refrigerant will be slightly flammable so it’s not that bad. The flame will go out once the flame is removed, it won’t catch fire and keep burning from what I learned

If it were not for fire codes, the charge limit for R290 could be raised. Large R717 (ammonia) systems have safety features in place, to minimize spillage in case of damage or a leak. There is no excuse not to be able to design certain commercial systems and possibly domestic systems with these safety features. Eventually, natural refrigerants should win out over these manufactured halogenated gases. R290 already has limited use even here in the USA in smaller units like regrigerators and window shakers.

So how do you actually charge this unit with a gage set and a scale. How much refrigerant is in your hoses. And it isn't like r 22 when the compressor is locked up and blows the terminals out of the compressor how big will the explosion be.

Why A2L flammable R32 or R290? When we had A1 non-flammable since 1928? Also do you know that the components of an R32 unit is the same as A1 R410A? Do you know you must tell your customer AT the POINT OF SALE that they will have a flammable or explosive refrigerant in their unit! and they can not have an open flame? You guys should read user manuals before thinking R32 is a future refrigerant., definitely not what the EPA plan. Try to read the ASHRAE 34 classification. R32 is a con and been pushed by Daikin the patent holder!. Be safe and make sure your customer be safe

The manufacturers are going to have to figure out which ones they are going to use, I am only going to carry one additional refrigerant in my van, it's a van not a frieght train! R-32 is time-tested overseas and appears to be the better choice. If you are a manufacturer thinking of using R- 454 B you better think again, chances are not good that I would ever purchase this product. Carrying refrigerants in a van requires two cans, one which is open and one full can, unless Ford can add three feet to my van, that's not going to happen with 4 cans. I will carry 410 A and one other refrigerant along with reclaim tanks - PICK ONE!!! The EPA and Industry leaders need to get a dose of reality and make better decisions as two refrigerants are not going to work at all.
