TM 10-4110-262-13&P

The amount of a refrigerant required by a refrigeration system to operate

Refrigerant

properly. The refrigerant charge is usually measured by weight.

Charge

One of the two components of the ADR-300 system. The RU is the mechanical

Refrigeration

system and associated controls that maintain the temperature inside the IC at

Unit (RU)

the required set point.

A component of the Refrigeration Unit that includes the mechanical components

Refrigerator

for transporting the refrigerant from the cold section to the hot section and back

to the cold section.

A device that switches an electrical circuit on or off based on a secondary

Relay

control circuit.

The pressure at which a fluid of a given temperature will exist in both liquid and

Saturation

vapor states. Saturation pressures of a refrigerant determine the evaporator

Pressure

and condenser coil temperatures for a given refrigeration system.

The air temperature inside the IC that is being maintained by the RU.

Set Point

Product Quality Deficiency Report the form to be used to report design or

SF368

operational deficiencies or recommendations for improvements to the ADR-300

system

A valve that is opened or closed on the basis of an electric control signal or

Solenoid Valve

voltage. The ADR-300 uses a solenoid valve to direct the flow of refrigerant

during the defrost cycle.

The low-pressure (evaporator) side of the refrigeration system.

Suction Side

Wires are tagged or marked to indicate the terminals or mating wires from which

Tag Wires

they will be removed before a service operation. This insures that the wires will

be reconnected properly after the service operation is completed.

The component of the RU that is used to input commands to the refrigerator

Unit Controller

control system. The controller includes a digital display and input keys for

inputting and modifying stored information.
