Compressor

Moves the refrigerant through the system. Pressurizes the refrigerant for

heat dissipation in the condenser.

Condenser

Dissipates heat from the compressor and refrigeration action.

Condenser Fan

Circulates air across the compressor and condenser to facilitate heat

removal.

Dryer

Cleans and removes moisture from the refrigeration system. A standard

dryer was in use for the SLJ until recently. The dryer currently in use is a

Parker style dryer. The Parker distinguishes itself by having two inlets and

two outlets. When ordering a new dryer, it is important to specify which

dryer is needed. The dryer should be replaced any time the refrigeration

system is opened.

5.1 Air Flow

Airflow in earlier units such as the first revision SLJ model was brought through

louvered side panels and directed across the compressor and through the con-

denser. The second generation SLJ with the smooth side panels gets its airflow

from the bottom and directs it first through the condenser and then across the com-

pressor. On all models, the airflow passes from the fan blades into the condenser.

This increases the efficiency of the refrigeration system but allows dirt to build up

where it is difficult to see or remove. On the positive side, the condenser is

designed to maximize airflow and minimize dirt buildup. Even so, the condenser

should be cleaned yearly, and checked whenever routine maintenance is per-

formed.

5.2 Refrigerant Charging

Charging any capillary tube controlled system requires accurate charging equip-

ment and technique. The Cornelius/Wilshire dispenser is no exception. The

amount of refrigerant in the system actively determines the operating pressures

and temperature of its evaporators. It is because of this that it’s necessary to utilize

a refrigerant scale or graduated charging cylinder whenever charging a system.

Whenever investigating a suspect sealed system of this type, it’s important to

remember that its operating pressures are to a great degree determined by load,

ambient temperature and condition. If the unit appears to be under charged, check

first for a dirty condenser. If the unit is constantly running but not cooling, the
