REFRIGERATION PARTS DESCRIPTION (CONTINUED)
CAPILLARY TUBE
The capillary tube controls, at a steady rate, the flow of refrigerant liquid to the evaporator. It has
a very small inside diameter to keep pressure in the evaporator low while the pressure in the
condenser is high. It is the connecting link between the condenser and evaporator.
EVAPORATOR
The Evaporator is a heat transference device. It removes the heat from the air in a refrigerated
space and transfers it to the refrigerant liquid. This liquid evaporates into a vapor and is sucked
out by the compressor. The evaporator is mounted inside the refrigerated space of the cabinet,
directly below the delivery chute.
ACCUMULATOR
The accumulator traps any refrigerant liquid which did not boil off into a vapor before reaching the
compressor. The accumulator allows the refrigerant liquid to boil off as a vapor (preventing
damage to compressor). It also prevents suction line sweating. The accumulator is mounted in
the suction line on the outline side of the evaporator.
