Capillary
The capillary is a very small diameter tube that is
about 6 to 8 feet long. Its primary function is to
control the flow of refrigerant into the evaporator.
The flow rate of a capillary is determined by its
diameter and is critical to the proper operation of
the refrigeration system. If a capillary is
shortened, the flow rate will increase. Likewise, if
it is lengthened the flow rate will decrease.
Therefore, when repairing a refrigeration system it
is very important to cut the capillary as close as
possible to the outlet of the dryer. The capillary is
not replaceable separately.
Heat Exchanger
The function of the heat exchanger is to transfer
heat from the warm liquid flowing through the
capillary to the cool vapor flowing through the
suction tube. The heat exchange occurs where
the capillary is soldered to the outside of the
suction tube. This arrangement improves the
efficiency of the system. By reducing the heat of
the capillary, the boiling point of the liquid entering
the evaporator is lowered. Increasing the heat of
the suction tube increases the density of the vapor
entering the compressor and also helps to prevent
the suction tube from sweating.
