Chris, I didn't know if you knew that R-290 is considered to be a Chemical Oil Solvent (C.O.S.). It can mix with the oil in the compressor and help with oil return in ultra low refrigeration systems.This would be systems cooling below -40 degrees Celsius. The R-290 is introduced into the system when first charging the system from a vacuum, almost always by pressure. After the R-290 pressures stabilize, the refrigerant is added, also by pressure as per manufactures specifications. A majority of medical scientific researchers use freezers the are cascade systems or mixed refrigerant auto cascade systems that will cool from -86 Celsius to -150 Celsius. These were fun to work on when everything went right, and a P.I.T.A. when things went south. Thanks for the videos! Nice to see your level of professionalism and dedication to the trade.

Just as a suggestion, look for a good set of goatskin gloves. They're usually sold for gardening, often in the women's glove section. They're not so good for heavy punctures, but they give you some wear resistance, as well as insulation against heat (or cold). The good ones are tight, and that's good and bad. It's good because you get really good dexterity and grip. It's bad because it takes a bit to get them on and off. I agree with you on hating the normal heavy gloves used for welding. (I don't believe they making brazing gloves. Just welding) You can also buy mechanics gloves with leather palms and fingers. That gives you the protection from the heat, with some flexibility. You just aren't that protected with synthetics, because they melt. Even cotton gloves are better than the standard mechanics gloves. Thanks for the videos!

Chris good job, on the end of the pipes I always pinched off the end of the tube and smashed it flat bent it over on itself smashed it flat again, and then brazed it shut, just my OCD thing. lol I used to work on University lab equipment and did a system that used R-602B exotic gas it came in a small really thick bottle with 1/2" steal, the return core fee was $2,000.00 and it held 8lbs of gas/liquid which was $4,000.00 itself. This was warranty work for the factory of the test chamber they flew out an engineer to oversee the work, I asked him what the weigh-in weight was supposed to be and he said they didn't go by weight just 185 PSI static pershers I was like really? he said yes. A loose screw had rubbed a hole in one of the lines, and all the gas had leaked out shortly after delivery on the $200K test chamber, a socket wrench and Lock Tight fixed it along with two small brazes. We made $25K for two hours of work and the factory reimbursed us the full price of $6K for the gas and bottle they had us store it at our shop for further use. My boss the owner of the company was Hell Yes. Easy money! lol

I have used those pinch off tools in the past. But have changed to using the yellow jacket pinch off tool. Once I pinch I keep my probe on then loosen the probe to depressurize, then tight probe back up and look for increase in pressure to make sure it’s not leaking. If it does I tighten the block up and retest. In the video once you pinched then started your torch to check for leak by, that was almost 20 seconds. That could have threw off your critical charge if is was leaking by. Not being mean just giving you my view/ opinion.

Talking about sweeping the system, when I trained to be an aircraft tech they talked about what you have to do to do "hot work" on fuel tanks. They purge/sweep the tanks with high temperature steam, and I think for an absolute minimum of 24 hours. Of course kerosene is a lot less volatile than propane, but still, it's not that surprising to me that you sometimes get flames after such a short purge with nitrogen.

@GGigabiteM3 жыл бұрын
Government regulations pushed for R1234yf to replace R134a, which is lethally toxic. R1234yf decomposes into carbonyl fluoride and hydrogen fluoride when exposed to the atmosphere. Both chemicals are on the "get the fuck out as fast as possible when a leak happens" because just a small whiff of either can cause death or debilitating health issues. Fluorine is the gift that keeps on giving, you can find plenty of videos on why chemists hate working with it. I'd rather have another flammable gas than liquid and gas death flowing around my vehicle. German car companies did R1234yf testing when it was introduced and were horrified that in crash testing it *etched into the windshield* This happened because both of its products of decomposition (HF and carbonyl fluoride) eat glass, as well as many other things, like human bone. It's also interesting that Dupont Chemical is the company behind R1234yf, as well as R134a and R12. And that there is always a big public scandal about how each previous refrigerant is bad for the environment right when the refrigerant is about to have its patent expire and become widely and cheaply available. It's also interesting how Dupont has a revolving door relationship with the EPA, where executives shuffle in and out of both doors. It couldn't possibly be a conspiracy where they regulate themselves and create artificial barriers to keep themselves the only show in town. R134a is currently around $100 for a 30 pound cylinder. R1234yf is about $3000 for the same 30 pound cylinder.
@etherealrose21393 жыл бұрын
Not sure why. R134a runs at about 16PSI less for the same temperature. I think it's a wash to totally change out components for a refrigerant that's about the same. You shouldn't need to be filling it so availability shouldn't factor in.

That's an issue of the compressor and TXV. R290 can work just fine if compressed to high enough pressure to raise the heat above ambient and expel it and then metered correctly at the TXV to drop the pressure so low it'll absorb the heat. It's a design thing.. saving money or maybe safety but I doubt that. Propane can be safely pressurized to 200 PSI. So I'm guessing money on less metal and smaller compressor that can run on 120V

There is a Delfield KZfaq called Delfield Tech Talk, late last year for R290 they said not to use the combustible leak detector no more because over a period of time it doesn't pick leaks no more so they said to add a trace of R404 and use your electronic leak detector. The Carel controller has a differential of 5*, that is what the setpoint is the CI will be 2.5* above the setpoint and the CO would be 2>5* below the setpoint. Check out the Delfield KZfaq site and maybe you can reply on it, FYI thre is a manufacture out there that sends the R290 equipment with a suction service already installed{I am not going to mentioned the manufacture for obviously reasons because the company I work is a warranty authorized company.

Every hydrocarbon leak detector will eventually loose sensitivity. Which is why they should be tested regularly and if it is a halfway decent model will have a replaceable sensor.

That is if there is a suspected leak not to leak check he confirmed that he had a leak with the bubbles and the reason was because the sensitivity on the diode lessens over time but still use as a combustible gas leak in the background so if they did not want it used at all then they would don't use it at all
