Air Filter Correct Answer - A filter made from glass fibers or
other media with fine openings used in an air conditioning system to
trap out small particles in the air.
Air Diffuser Correct Answer - An air grille in an air
conditioning system that blows cooled air into a space and also
starts a mixing action of cooled air with room air.
Subcooling Correct Answer - The cooling of a liquid refrigerant
below the saturation temperature corresponding to the refrigerant
pressure.
Air Defrost Correct Answer - The process of removing ice or
frost from a refrigerant coil by blowing air over the coil, the air
temperature being above freezing.
Air Cooled Condenser Correct Answer - A refrigerant
condenser in which the refrigerant discharge vapor from the
compressor is introduced inside the tubes of the condenser and
atmospheric air blown over the outside of the tubes to remove heat
from the refrigerant vapor and condense it to a liquid.
Saturation Correct Answer - The condition when heat energy
that is transferring in or out of them is latent heat.
, Hermetic Compressor Correct Answer - A combination motor-
compressor unit in which the compressor and electric driving motor
are mounted on a common shaft and the motor and compressor are
encased within a welded steel shell.
What are the functions of oil? Correct Answer - Lubricating,
cleaning, cooling, and sealing
Temperature Correct Answer - A measure of the intensity
(molecular vibration) of heat energy in an object.
Superheat Correct Answer - The raising of the temperature of
a vapor above its saturated temperature while remaining at the
saturation pressure.
Air Conditioning Correct Answer - The simultaneous control of
temperature, humidity, air cleanliness, and air motion as required
for comfort or industrial processing.
Viscosity Correct Answer - The measure of the pour of flow
characteristics of a liquid.
