tion refrigerator and while it kept stuff cold enough that it didn't spoil it certainly didn't keep stuff as cold as a vapour compression refrigerator. The wikipedia page on Kerosene lamp gives some hints as to why kerosene burning fridges vanished without invoking any conspiracy: cost, smell, and soot. Given patents have a limited life (20 years in the US) and are public knowledge it is hard to see if these type of refrigerator was a valid competitor how anyone could have kept it quiet all this time. -- BruceGrubb ( talk) 07:43, 4 June 2008 (UTC)

Just curious, the page states that the machine caused numerous deaths due to leaks of ammonia, but when I read about Ammonia on Wikipedia it hardly looks like such leaks could cause numerous deaths. I know little about chemistry, but either the health risks in the article about ammonia are understated, or the information here about it causing deaths is inaccurate.
About a year ago, I was involved in a small ammonia leak. I was holding the end of the pipe it came out of, so I inhaled a good bit of ammonia. (It was coming out gaseous, not liquid, or I would have gotten the hell out of there). I am unaware of suffering any fatality from the incident. Ammonia is not toxic, contrary to popular belief. It is a simple asphyxiant. (To be more precise, it may be toxic in doses much larger than would be needed to suffocate you to death.) 71.232.212.29 05:18, 18 June 2006 (UTC)
we used to have one that ran on propane gas. --Will314159 14:56, 16 May 2006 (UTC)
Ammonia is toxic, but unlike some other dangerous gases (especially carbon monoxide -- odorless and tasteless) its scent is strong enough to drive one away before one gets in trouble. Ammonia would prove hazardous to anyone unable to get away. It is far less dangerous than chlorine, which has been used as a refrigerant gas.
Yes, ammonia in small concentrations is very unpleasant, and gives ample motivation to leave the area. If someone inhaled a large enough concentration at one time to pass out, then there is danger. Ammonia is about half the density of air, so the fumes tend to rise. One would have to be trapped in an enclosed area to get a fatal dose. Jokem ( talk) 19:48, 23 June 2009 (UTC)
I think someone needs to look at merging and rearranging the material on Icyball, Absorptive refrigeration, Gas absorption refrigerator and Einstein refrigerator. (It might be me :) njh 10:31, 3 February 2006 (UTC)
I believe that the article may have the refrigerant and the "pressure equalizing gas" reversed. I believe that ammonia is used as the refrigerant and the butane is used to provide a partial pressure in the evaporator to allow the ammonia to evaporate. Ammonia is readily soluble in water but butane is not, therefore water may be used as a trap that will keep the butane in the evaporator but allow ammonia to pass from evaporator to condenser. I believe that this is just another design of the absorption refrigeration cycle.
"Modern Refrigeration and Air Conditioning 18th Edition (Hardcover) by Andrew D.; Bracciano, Alfred F.; Turnquist, Carl Harold Althouse" has a chapter discussing absorption refrigeration and how its implemented in commercially available appliances.
Absorption refrigerators are still used in recreational vehicles where they are heated by propane when electricity is unavailable but with an electric heater when electricity is available.

Refrigerators that sound a lot like this are in use on boats and RVs, where propane gas as a fuel source is much more practical than electricity-- Mongreilf ( talk) 14:21, 30 March 2008 (UTC)
Would the Einstein refrigerator be suitable for use as an air conditioner? The mechanical principles behind refrigeration and air conditioning are quite similar, and the obvious difference is that air conditioning units are designed to send 'waste' heat outside of the enclosed building. (Refrigerators as a rule send the waste heat into the room in which the refrigerator runs).-- Paul from Michigan ( talk) 12:50, 6 October 2008 (UTC)
Instead of a heat pump, could a mere solar mirror, fresnel lense or concentrator be used. Seems quite expensive otherwise. 81.246.189.106 ( talk) 13:22, 3 December 2008 (UTC)
I wish someone would give a better explanation of the operation. Nothing says which components are the evaporator and condenser, which fluid is butane, etc. Jokem ( talk) 04:44, 26 July 2009 (UTC)

Two or three edits ago, this was deleted from the article. I reverted and criticised that deletion. The OP responded by rephrasing thus.
IMHO this is somewhat silly.
Speaking of
is really not all that different from talking about
Who are we kidding? The implication is exactly the same. Whether explicitly or implicitly non-toxic, both paragraphs still make it very clear to the man on the Clapham omnibus that Freon is, per either edit, supposed to be considered non-toxic and less harmful. I know this turn is partly my own fault, because in a highly literal sense, the OP has given me exactly what I asked for. Nevertheless, I stand by my earlier critique, and I can't help but wonder, why this eagerness to paint Freon in a positive light – and why so averse to any mention of the unforeseen but subsequently revealed major planet-scale side effects of its use? — ReadOnlyAccount ( talk) 20:09, 5 January 2024 (UTC)
