No, these are not in a field with tannerite. They are being used in homes.
Check this out:
"I just thought it was an earthquake, big explosion," said Lenore Satterthwaite after she says her refrigerator exploded. "I was on the computer. I thought it was an earthquake it was so loud and I came in and the doors were on the floor and the holes in the wall."
Satterthwaite has dozens of pictures and videos to show the destruction throughout her home after she says her less-than-a-year-old Frigidaire refrigerator exploded. In the pictures, you can see the outside shell of the appliance is still in its place, with everything inside of it scattered all over her kitchen. The force was so great, it damaged her stove, walls, and furniture.
and a possible Explanation <<<
From the comments Anon mentions R1234yf refrigerant. Here is the SDS <<
Made by Dupont Honeywell.... <<<
CHINA: Honeywell has won the latest round in a continuing series of court battles between refrigerant manufacturers over the automotive air conditioning gas R1234yf.
In the latest episode, at the end of last month, the Supreme People’s Court in China upheld the earlier findings of the Beijing IP Court and the China National Intellectual Property Administration that the claims in Honeywell’s application patent (No. 201210530088.9), which cover the use of HFO-1234yf in automotive air conditioning systems, are valid. The court also dismissed Arkema’s challenge to these claims in China.
Extremely flammable
I just looked at the fridge we have in the kitchen and it's using R600a. Irish
This is all just a PSA FYI. When I saw the news story it caught my attention. That's all.

Freon is generally considered non-flammable so the possible explanation is BS. Even if it were flammable, there would need to be air (oxygen) available for a thermobaric event. There is no air in the system so the compressed freon never encounters it. If it does escape, the act of decompressing from high pressure side to atmospheric causes it to cool down.
ReplyDeleteFreon was outlawed years ago...
DeleteIf the refrigerator had R1234y and not R134 that is the reason. R1234y is explosive and used as a refrigerant more and more in all applications including cars. R134 is not explosive its been used for years and is a standard in appliances, cars and most every application, till R1234y came out due to government environmental rule changes. R1234y is expensive, dangerous, and I can find no environmental benefit except you use less of it.
ReplyDeleteThe news story glosses over this dangerous changes to Freon that the government has mandated. I dont think in all the past years anyone has had a refrigerator blow up to that extent and this could be the reason why.
Fridgedaire uses R600a in their refrigerators. 1234yf is not approved for refrigerators
ReplyDelete...another hydrocarbon. Isobutane.
DeleteThis is what happens when they replace the perfect refrigerants, CFCs (gasp, Ozone Hole) with HFCs (Oh God, Global Warming) and now Hydrocarbons.
I finally left HVAC after working Commercial HVAC for 40 years and then 'trying' to teach it for three years. I saw the last revisions to the refrigerant certification a few years back when they R410a would be the replacement and Hydrocarbons would stay in Europe. No such luck.
To make matters worse HVAC requires a minimum of algebra level math and physical science/physics. I'd get students that could barely read and could barely add or subtract w/o the calculator app on their phone. Out of 30 plus students that started the course 1 or 2 might finish it and maybe one of them would make it in the field.
Good Luck.
The cost to service an automotive ac system or any system recharge is about 4 times as much and not all will do it.
ReplyDeleteThey haven't built a decent, reliable appliance since the 1980s.
ReplyDeleteAnother problem brought to you by a .gov "solution" to a non-existent problem. Nothing new here.
ReplyDeleteRemind me again why we got rid of R12 and R22? Oh yeah, patents were expired and DuPont wasn't raking in the dough.
ReplyDeleteR-600 is basically butane; Isobutane is an isomer (arrangement of the carbons in the molecule) so its physical properties differ from plain butane which make it usable as a refrigerant. Our LG fridge uses 2.1 oz of the stuff which is 60g so just over a mole (butane=58g mol wt). That is about 23 liters of gas atmospheric pressure....
ReplyDeleteIt has about three times the energy of combustion as natural gas(methane) and about half that of gasoline.
If it leaks it has a sweet smell, but probably not a noticeable as the odor in nat gas from you stove, furnace or water heater.
Wish I was still ignorant of the above; now I will worry.
Got rid of my POS Frigidare last year & replaced it with a whirlpool.
ReplyDeleteThe difference in quality & service is startling.
The worst thing to happen is was ice getting stuck in the chute, easily remedied.
Fuck Frigidaire.

R600A is Isobutane. When I bought my chest freezer it had that warning label on it. I bought a gas alarm for it. Butane is heavy and flows on the floor. So, the alarm is right on the floor near it. Natrual gas is light and floats to the ceiling. I have one up there, too.
ReplyDeleteThere are all kinds of gasses we could use for refrigeration. Heck air would work with the right system. This earth worship cult is madness.
The problem is not the refridgerant, but the heat build up. If you install the fridge in a poorly ventilated space, the heat build up can cause the coils to expand and kink, trapping the gas. Then boom.
ReplyDeleteAlways install a new fridge with the correct manufacturers spacing on the top/bottom/sides and back.
Maybe when you put a 6 pack of Bud Lite in the fridge it causes it to blow
ReplyDeleteAnd then you get shit canned.
DeleteI would also bet that if these jihadi fridges had not been installed properly (easy to check the side/top spacing after the fact) and that the insurance company would tell you to suck it.
ReplyDeleteAnd if you're in the construction/kitchen business (I am and have been for 35 years) don't ever let a customer talk you into installing something not per manufacturers specifications or instructions. Ever.
Fuck, just go back to using Ammonia....
ReplyDeleteor Propane. I had a very old cooler that used propane as the refrigerant (it had a compressor, not the kind that uses a flame to move the gasses). Nearly any gas that will compress can be used as a refrigerant, if done properly.
DeleteBoy do I have an appliance story or two.
ReplyDeleteMeh just fill the fridge with Acetylene gas it should be good for another year.
