REFRIGERATOR OVERVIEW

ABSORPTION COOLING SYSTEM

In an absorption refrigerator system, ammonia is liqueed in

the nned condenser coil at the top rear of the refrigerator.

The liquid ammonia then ows into the evaporator (inside the

freezer section) and is exposed to a circulating ow of hydro-

gen gas, which causes the ammonia to evaporate, creating a

cold condition in the freezer.

When starting this refrigerator for the very

ﬁrst time, the cooling cycle may require up to

four hours of running time before the cooling

unit is fully operational.

The tubing in the evaporator section is specically sloped to

provide a continuous movement of liquid ammonia, owing

downward by gravity through this section.

Sodium chromate is used for corrosion protection less than

2 weight % of the coolant.

LEVELING THE REFRIGERATOR

Leveling is one of the requirements for proper operation with

absorption refrigerators. To ensure proper leveling the vehicle

needs to be leveled so it is comfortable to live in (no noticeable

sloping of oor or walls).

Any time the vehicle is parked for several hours with the refrig-

erator operating, the vehicle should be leveled to prevent this

loss of cooling.

If the refrigerator is operated when it is not level and the vehi-

cle is not moving, liquid ammonia will accumulate in sections

of the evaporator tubing. This will slow the circulation of hy-

drogen and ammonia gas, or in severe cases, completely block

it, resulting in a loss of cooling.

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

rolling and pitching movement of the vehicle will pass to either

side of level, keeping the liquid ammonia from accumulating in

the evaporator tubing.
