atmospheric air Answer: A mixture of various gases and water vapor in the
earth's atmosphere.
Capacity Control Answer: In mechanical refrigeration, a controlling method
for reducing the heat displacement ability of the system.
Condensate Pan Answer: A container located under an evaporator to catch
defrost water.
condense Answer: Change to a liquid state.
Defrost Cycle Answer: A sequence of operations used to remove frozen
moisture from an evaporator and restore it to full efficiency.
Defrost Terminator Thermostat Answer: A control used to disconnect the
defrost heater when evaporator temperature reaches about 50°F (10°C). This
device prevents the heating of an already defrosted evaporator and stops the
