Absorption gas refrigerators for home use
Servel was the big builder and seller of these in the United States, about the only advantage of them is they were quiet in operation.
They lost out because they didn’t have the reserve capacity to keep up with really hot weather, and they actually cost more to run in most cases because the absorption cycle is not as efficient at moving heat.
The recall that is still in effect mainly came from the fact that people were taking old home refrigerators designed for natural gas and trying to convert them to LP gas to use a hunting cabins, etc. quite a few people were killed by the carbon monoxide they produced. This happened because they weren’t converted properly and they weren’t really designed to be converted at all. Plus they were being used to confined space.
The one that David Allen has we gave him. I almost turned it in for the thousand dollar bounty on it, but I figured it should be preserved.
Later, frost free models that whirlpool built such as the ones that were in the Beverly hillbilly show had more cooling capacity. They were able to get them to work a little better by adding condenser fans, etc. so they worked in warmer weather, it was interesting the frost free models they didn’t even have to turn off the cooling when they wanted to defrost the evaporator they simply turned on the electric heat and it quickly overpowered the cooling effect of the gas refrigeration melted the ice, and then they just turned the heater off, and it went back to cooling.
I had a funny warranty call on a whirlpool refrigerator about 35 years ago. The customer complained it was Noisy and whirlpool refrigerators in the early 80s were about the quietest refrigerator You could get on the market because of their very efficient Segger designed rotary compressor.
When I couldn’t find anything wrong with the refrigerator except the slight hum of the compressor, I asked the customer what kind of refrigerator did you have before and she said it was another whirlpool , I moved the new whirlpool refrigerator away from the wall just to check and make sure nothing was lose rattling, etc. and I noticed a gas line behind the refrigerator that had recently been capped, I asked the customer was your old refrigerator gas she said yes it was a gas whirlpool which I guess was the reason they were not accustomed to any noise at all associated with the refrigerator, lol I guess they just had to get used to the new whirlpool.
