In an absorption refrigerator system, ammonia is liquefied

in the finned condenser coil at the top of the refrigerator.

The liquid ammonia then flows into the evaporator (inside

the freezer section) and is exposed to a circulating flow of

hydrogen gas, which causes the ammonia to evaporate,

creating a cold condition in the freezer.

The tubing in the evaporator section is specifically sloped

to provide a continuous movement of liquid ammonia

downward by gravity through this section. If the refrigera-

tor is operated when it is not level and the vehicle is not

moving, liquid ammonia will accumulate in sections of the

evaporator tubing. This will slow the circulation of hydro-

gen and ammonia gas, or in severe cases, completely

block it, resulting in a loss of cooling.

Any time the vehicle is parked for several hours with the

refrigerator operating, the vehicle should be leveled to

prevent this loss of cooling. The vehicle needs to be

leveled only so it is comfortable to live in (no noticeable

sloping of floors or walls).

When the vehicle is moving, the leveling is not critical as

the rolling and pitching motion of the vehicle will pass to

either side of level, keeping the liquid ammonia from

accumulating in the evaporator tubing.
