JG/OZ is at it again

Here is the reply from an Austrailian refrigeration engineer after our freindly Austrailian HC peddler was found pushing his wares on a refrigeration website.

Wake up mate, I'm sure 99% of avg aussie fridgies are all for reducing greenhouse emissions etc but not at the cost of lives. Note: Average aussie fridgy is NOT a paper writing ponce who sits behind a desk all day reading his latest toss to the industry in celcius or CCN. I mean the real fridgies you see at kirby's and lovies every day buying the cheapest gear they can to sell for the highest price and make the most amount of money.
Thats what we are all in it for - $. If you're not then go join greenpeace and fix fridges for charities all day... Yeah right. You just can't go selling units with HC's one day, its gotta have a BIG education program, thats why old matey died, you put something flammable in it you change the whole playing field, even if it is just enough charge to blow the door open in a domestic fridge, do you want your door blowing open, not me, rather CO2.
By the way, I've heard quite few differing stories on that HC incident, even saw the photos, looked like a kirby condensing unit from the photos (about 5-10 yrs old), in a small room with no ventilation and running off extension lead poked in from adjacent room, what photos did you see? Who did you hear the story from coz we maybe stupid in oz but not THAT stupid, to overcharge with a gas that running lower pressures to the point where you blow out a hi side u bend... come on mate, don't make us look stupider than the croc hunter already does! He unplugged a unit that had been leaking in a small room with no ventiliation, he unplugged the unit from its extension lead, air was between 2 and 10% HC and kaboom. NOT his fault unless he installed it, shouldn't have happened for too many reasons to mention, the main one being EDUCATION. He may have been a cowboy, but if taught even a cowboy can do more than ride horses.
I worked on HC units at 2000 olympics for maccas, yes they used patty and nugget freezers on care 30 I think ( been a few years now, maybe 40 or 50) we were all trained for it, all good, no dramas.
HC's are fine for big AC chillers, flashproof switchgear etc all the precautions necessary can be taken, same with industrial fridge, the customers will spend the money to save $ in the longterm, you don't get this in commercial ac and fridge, its bottom $ or bust, I'm sorry but where HC's are concerned any compromise is too much and too many people have gotta make a buck out of this game to feed their families. If your avg walk in coolroom ends up on HC's I'll be a handing my ratchet key and shifter in and moving onto industrial fridge wher all the safety precautions are taken.

Ha, talk about a language barrier, exactly what are you saying, Karl. I am searching for an English to English translator, haven't found one yet, LOL.

This sites' spellchecker isn't working this morning, maybe that is the problem.

That was a reply from an Austrailian refrigeration engineer when jg/oz advocated the use of HCs in walk in cold rooms and refrigerators. The gist of his reply was that he wasn't too keen on the widespread use of HCs in refrigeration, giving an example of one "Fridgie" blowing himself up.

He also commented that jg/oz was making Austrailians look as daft as the film Crocodile dundee has. The writer is not known for suffering fools, I'm sure that you can figure out the rest.

My point is that the Aussies aren't as keen on HCs as some would like us to think.

Ha, you shouldn't judge an entire nation just because of what one or two may say, but that seems to be the common way of thinking.

Not judging Nick,

What is common practice in one part of the world may be taboo in an other, and we only have one guys word. The impression that I got was that HCs were a common thing in MVAC in Australia, since we dont have too many Aussies on this board, we had no info to the contrary. On the Buick board a very bold statement was made regarding German domestic vehicles being charged at the factory with HCs, perhaps they thought that nobody from Europe would see it and challenge this. Over here HCs are widely used in domestic refrigerators, but these are factory built and have no service ports

I think we all have learned that the propaganda these HC proponents preach is subject to debate. I do believe that HC’s are readily available in Australia. But if you buy into the HC hype the US has over 100,000, 000 user hours of auto HC use. While we do see some HC contaminated systems most are contaminated with R12 and R134a.
