Absorption fridge tests and new safety device
I have been stating for YEARS that operating an absorption fridge off level of ANY AMOUNT affects the fridge in a bad way... Well, I noticed on a different RV forum that there has been some testing...

Interesting.......but what amazes me is that if the fridge should sit level, why in the heck is the rv builders cabinetry skills so out of level. I can get my trailer level but have noticed, not just on mine, that the surrounding cabinets are not. Poor quality control all around.
RV builders simply use the manufacturers "tolerances" given, it isn't the "builders" job to make it "dead on" plumb or level, it is the END USER that must ensure the fridge operates as efficient as possible.
The data that they have collected clearly points the fact as I have argued so much about on this forum that level MEANS ABSOLUTELY 100% IN THE BUBBLE.
The fridge manufacturers have a lot to gain (and hide) by allowing lax tolerances to being off level.
By BLINDLY following the published 3degree/6degree tolerances from the manufacturer the end user is SHORTENING the actual life of their CU. And from the gathered data I would have to say that even slightly out of level DOES affect the cooling unit by raising the boiler temps well above normal operation.
Pretty simple, the entire CU relies on gravity and is most efficient when completely level.
Why?
Simply put, a slight change in the orientation of the tubing causes more resistance to fluid movement inside the tubing. It basically increases FRICTION inside the tubing and FRICTION slows down the movement inside the tubing.
"Dead On" level represents the LEAST AMOUNT of friction encountered inside the tubing... Therefore IS the "best way" to operate your fridge.
Kudos to those folks on the other forum, the data they are collecting just might help folks SEE the real facts in how the fridge works...
