Sealed System - Heat Exchanger

The heat exchanger consist of a suction line and a capillary tube that are brazed together. The heat

exchanger is the means that connects the evaporator to the compressor through the suction line and to

the outlet of the drier by way of the capillary tube. 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.

NOTE

: The heat exchanger is foamed into the cabinet of the refrigerator. However, if any part of the heat

exchanger (suction or capillary tube) fails due to restriction or leak, a replacement heat exchanger can be

installed, order part number WR85X10077.
