Country: Sweden

Company: Electrolux, Servel

Individual Holding Patent: Albert Einstein

over heart When ?

off level the temp is right , but fluid is not returning to correct point in the system

over heat during a malfunction ? I think that would require some kind of internal pressure switch, burner seldom fail my getting to big a flame and too much heat

a leak in the system creates a loss that raises pressure, the fire happens when the hydrogen gas leaks/erupts from the bursting pipes

i think that infamous recall fix from a few years ago
involves a heat sensor
and the electronics can only be reset a limited number of times
then the whole thing has to be yanked and replaced !

I wonder why they don't have a simple thermostat to shut off the flame when the system overheats.

If the story of the invention of refrigeration interests you, you might enjoy reading the book White Banners by Lloyd Douglas. It's a fictional account, but it is a gripping tale.

"3. They don't need to be level. (Design their internals that are level-sensitive so that they're supported by a gimbal mechanism OR mount the entire refrigerator within a gimbal frame.)"

This is exactly right. It seems like a no brainer. Perhaps the fridge would have to be smaller in the frame to self level, or the fridge body need to be bigger to accomodate the gimbal. But it would also need to be locked for transport. Going down the road it would swing about. I just wish they would do it.

The original question was absorption refrigerator not RV refrigerator. The Crosley Icy Ball was I'm pretty sure not the first, but it was pretty unique and the patent was issued in 1929. Here is a link to more than you ever wanted to know about them. http://crosleyautoclub.com/IcyBall/crosley_icyball.html I have one and it still works. My guess from the style and serial number on mine that it was made around 1928. I know of a couple of modern version if the Icy Ball that was made to take camping for cooling.

I'm a gas absorption refrigerator fan for RV use. They're the ultimate solution to RV refrigerated food storage, IF:

1. They're built well and with safety features - but still light in weight. (These characteristics don't always have to be mutually exclusive.)

2. They're installed properly. (This is sometimes a problem for the RV manufacturers.)

3. They don't need to be level. (Design their internals that are level-sensitive so that they're supported by a gimbal mechanism OR mount the entire refrigerator within a gimbal frame.)

You see numbers 1. and 2. not being complied with all the time. Number 3. is still waiting to happen.

You beat me to it. A fridge that weighs half a ton is in no way superior for an RV application.

Admittedly some of the newer electronically controlled ones have some issues but I'm aware of several RV fridges that have been trouble free for 20-30yrs...which exceeds the typical life cycle of an RV. Once it lasts the life of the RV, additional lifespan really doesn't provide any benefit.

There is one for sale on eBay for $50, apparently non-working tho.

Electrolux/Servel name were still used in some RV's until about 1979 to 1981. I believe that Dometic either purchased Servel or they merged some companies into the Dometic brand in early 1980. The original Dometic refer was built in Sweden until they built a Plant in Elkhart, Indiana in the early 1980's. Doug

We have friends from the states who own an island in Canada in Lake of the Woods. They have a 45 year old Servel gas absorption refrigerator which has been in their family that long. They use it in the cabin. They go up every summer for 3 months to live off the grid, then shut everything down and return to the states. In 45 years the fridge has never failed.

dr john gorrie of appalachicola invented the system of evapeorative cooling in 1851, long before Edison .
