grover posted:If propane is such a great refrigerant, why don't we use it instead of R-134a? House a/cs were on r22, fridges on r12. Notice that car a/c were on fridge gas, not a/c gas. Lower pressures of fridge gas was desirable on car a/cs due to their increased risk of leaks. Propane (and by that I mean r290, which is purified propane with moisture removed), is still way up there with a/c gas (r22) as far as pressures, better to have a lower pressure gas , a fridge gas in it. r134a doesn't stress the system so much and may not leak due to it's lower operating pressures. House a/c went up in pressure to find a replacement (r22, r407c, r410a and maybe propane - r290) Car a/c need to find a fridge gas to replace it after r12, r134a is an equally low pressure gas, but commercial fridges went to r404a or r507, which are higher pressure, also domestic fridges went to r600a (isobutane) So realy no obvious replacements for a non flammable low pressure efficient refrigerant to replace r12. May as well stick with r134a. I hate r134a, way better refrigerants. But if the world is 'going green', the 'global warming potential' as rated by scientists is a lot lower than other , better refrigerants or hydrocarbons unfortunately. edit: V sorry Fo3 fucked around with this message at 18:49 on Dec 3, 2011 |

Australians arent allowed to do their own A/C work, or LPG work, Or home electrical work... Im just glad ive got a mate whos an A/C repairer because I get discounted work, otherwise its $150+ just for a regas.

How is it you all live in a country founded as a penal colony wherein every single living thing can murder you outright, yet you can't do anything remotely dangerous? Goddamnit, I'm derailing the derail. Getting back on topic, saw a car today with its front quarter panel duct-taped on. That's a first.

You Am I posted:I guess with AC stuff, stop loving idiots in the Australian community being bigger loving idiots, but makes it hard if you want to do a quick refill of your AC system. drat right. If I had the gear I wouldn't think twice about filling the car AC with an alternate refrigerant. It's going to cost me at least $2-300 to get it refilled legit and tested again and, well I don't want to. Last time I had it refilled they had it on their pressure testing machine for ages and it registered no leaks. He seemed to think the r134a system had been worked on by someone else in the past because it was a hot day and it got the cabin down to 8*C in the sun. I can't help but wonder what a less lovely refrigerant could achieve. Give me guidelines and I will follow them. Don't ban me from doing something because some P plater dumps a bottle of propane up his rear end or something. Anyway I drive around with an 80ish litre tank of LPG and a 65?L tank of petrol directly below it.\ and I'm not dead. I'm not scared of a small amount of hydrocarbon gas in an open area.

Maybe you people just need to take your doors off Works fine in Texas. Here in Florida, we get 80%+ humidity all summer long; that sorta puts a damper on evaporative cooling.

I lived in Corpus Christi (on the Gulf Coast and almost always 90+% humidity) and got by fine. Humans come from a part of the world that experiences these temperatures for most of the year (it's kinda why we have a mechanism for dealing with overheating).

So, uhm, don't drive around with leaky acetylene tanks in your FJ. Or something. http://www.fjcruiserforums.com/forums/general-discussion/139018-i-blew-up-my-fj-literally.html quote:i had an acetylene bottle in my truck, the valve was bumped so slightly and over night the truck filled with the gas. i noticed the smell, and opened the doors to air out the truck. i drove the truck out of the garage to get some more air movement. i went to roll the pass side window down and as soon as i touched the power windows. BAM. with me in the truck. i lost all hearing out of my right ear and got a scratch on the back of my head. all things considering, im alive.
