GLOSSARY

Term

Definition

A 300 cubic foot refrigerated shipping container consisting of an insulated

Advanced

container and a removable refrigeration unit.

Design

Refrigerator

The amount of heat that can be transported by the refrigeration system in a

Capacity

given period of time. The capacity of a system depends on the operating

temperatures inside and outside the IC as well as the physical condition of the

refrigerator hardware.

A screw that is retained by one of the components of an assembly that is held

Captive Screw

together by the screw. The ADR-300 condenser section cover includes six

captive screws to secure the cover on the condenser section. These screws

remain in the condenser section cover when it is removed from the system.

The process of adding refrigerant to the refrigeration system. Charging may

Charging

include adding a full charge to an evacuated system or adding refrigerant to a

partially charged system.

A device used to limit electrical current in a circuit. A circuit breaker is also

Circuit Breaker

used to cut off all power to the circuit it supplies.

A mechanical device used to raise the pressure of a contained fluid. The ADR-

Compressor

300 compressor pumps the refrigerant from the low-pressure side of the

refrigeration circuit to the high-pressure side.

That portion of the Refrigerator that is outside the IC. The condenser section

Condenser

exhausts heat to the outside environment.

Section

A device used to connect one or more electrical wires so that they can be

Connector

separated when necessary and reconnected.

An electrical device that switches a high voltage circuit on or off based on a

Contactor

relatively low voltage control signal. The ADR-300 high voltage system includes

two contactors that switch the motor and electric heater circuits based on 12-volt

signals from the PC board.

A continuity check is a measure of resistance between two points of an

Continuity

electrical circuit. "Continuity" means that there is a measurable resistance, or

Check

conductance, between the two points. "No continuity" means that there is an

infinite resistance or no conductivity between the two points.

The operating mode in which the ADR-300 cools (removes heat from) the

Cooling Mode

interior of the IC. The RU is normally in the cooling mode when the interior

temperature is above the set point.

The high-pressure (condenser) side of the refrigeration system.

Discharge Side

An electric arc from a charged body to a neutral or oppositely charged body.

Electrostatic

ESD is a "shock" commonly experienced, often in a dry environment, when an

Discharge (ESD)

individual touches a grounded object. ESD can seriously damage digital

devices such as the ADR-300 microprocessor.
