Three things must be remembered

when diagnosing a cooling unit:

First, circulation within the cool-

ing unit is totally gravitational. This

means proper leveling is important.

Second, heat

created to boil

the ammonia

now has to be dis-

sipated into the surrounding air. Heat

from the absorber and condenser must

also be dissipated so as to cool the

ammonia sufficiently.

Third, proper heat application at

the boiler section.

THE ABSORPTION SYSTEM

(26)

When diagnosing a cooling unit, remember this

is the only part we cannot field check with test

equipment, yet it is the simplest and quickest

part to diagnose.

After the unit has been operating for

approximately one hour, carefully touch the unit

at the boiler box and the absorber area. These

areas should be approximately the same

temperature, regardless

of the

ambient

temperature. Equal heat between the boiler and

the absorber indicates the fluid circulation within

the unit is good.
