Residential fridges

I wanted a 110ac refer but RobR pointed out that his refer works
great after 15 years. I set out to learn what makes cold from a gas
flame and understand more about my LP/Ammonia refer in the hopes
that understanding the dynamics can help with issues and operation.
My first misconception was that when the LP refer was run on 110ac,
a compressor took over. I now know that on 110ac power, the 110
runs a heater that boils the ammonia just like the Lp gas flame
did.

Then I wanted to learn why high end full door ammonia refers outlive
the small camper squarbox camp refers. It seem not to be that the
refers in the high end coaches were better built , I think it is
they last because they are taller.

The lp amonia refers have problems when they are run out of level.
I understand that gravity is a necessary force in moving the ammonia
through the gassing process. The slope of the tubes in back of the
lp refer are designed to keep the ammonia in motion. If the ammonia
stops moving because of out of level, the boiler may cook a blockage
in the tubes. On the road the slosh of travel overcomes the out of
level effect. A taller refer has a longer slope therefor less chance
that minor out of level operation will hold processing ammonia stale
in the pipes. likewise a short camper box refer would have less
elevation to make a slope and require greater attention to keep
ammonia flowing??????????

I like using the lp ammonia refer while drycamping but I wish they
made a hybrid AmmoniaBoiler/FreonCompressor refrig. It seems that
compressing freon has to be safer and more efficient than boiling
ammonia??
