return air temperature:
The temperature of the air
returning to the evaporator. See box temperature.
rpm:
Revolutions per minute.
setpoint:
The temperature selected on a thermostat or
microprocessor controller. This is normally the desired box
temperature.
short cycling:
When a refrigeration unit cycles between the
heat and cool modes more often than normal.
sight glass:
A system component that permits visual
inspection of oil or refrigerant level and condition.
thermostat:
A device that controls unit modes of operation to
maintain a selected box temperature.
TLE:
Thin-line evaporator. A Thermo King remote evaporator
designed to be compact (thin) while supplying superior air
flow. See
ECT
and
EW.
top freeze:
When the top portion of perishable cargo is
damaged by freezing temperatures discharged from the
refrigeration unit. This may occur near the front of the box
when product is placed too close to the cold, discharge air flow.
Vac (volts alternating current):
An electric current that
reverses direction at regularly recurring intervals.
Vdc (volts direct current):
An electric current that flows in
one direction only and is constant in value.
volts:
The basic measuring unit of electrical potential.
watt:
The basic measuring unit of electrical power.
