CFC:
Chlorofluorocarbon. A chlorine-based refrigerant
consisting of chlorine, fluorine and carbon. Example: R12. In
many countries it is illegal to release this type of refrigerant to
the atmosphere because chlorine damages the earth’s
atmosphere. CFC refrigerants are not used in modern Thermo
King units.
circuit breaker:
A thermal device that automatically
interrupts an electrical circuit when the current in the circuit
exceeds the predetermined amperage rating of the breaker. See
amp.
coil:
A cooling or heating element made of pipe or tube,
formed into a helical or serpentine shape, that may be equipped
with thin metal fins to aid heat transfer.
cold curtains:
Flexible vinyl curtains used to reduce air
exchange between the refrigerated compartment and the
outside during door openings.
compound gauge:
A gauge calibrated in psig (or kPa) to
measure pressure, and in inches of mercury (Kg/cm2) to
measure vacuum.
compressor:
The refrigeration component that compresses
refrigerant vapor and creates refrigerant flow.
condenser:
An arrangement of tubing in which the
vaporized and compressed refrigerant is liquefied as heat is
removed.
cycles per second:
See
Hertz.
damper door:
A door on the evaporator section that closes
during defrost to prevent hot air from entering the refrigerated
cargo compartment.
data logger:
An electronic device that monitors and stores
unit operating and temperature data for later review. Examples:
DMS, DAS, DRS and AccuTrac.
DE:
Dual Evaporator. A multi-temp host unit with two
evaporators capable of refrigerating two separate, longitudinal
compartments.
defrost:
The removal of accumulated ice from an evaporator
coil. Periodic defrost is necessary when the evaporator coil is
operating below freezing. Defrost is required more frequently
when the air passing through the evaporator has a high
moisture content.
defrost termination switch:
A component that terminates
defrost operation at a specific temperature.
