The design and production of this component involve the process where the copper capillary tube is soldered to the copper suction tube using fully automated equipment in various lengths according to customer orders. This connection results in improved heat transfer efficiency.
The capillary tube is responsible for reducing the refrigerant pressure and transferring it to the evaporator, while the suction tube is responsible for transferring the refrigerant gas from the evaporator to the compressor. This process ensures that the refrigerant gas enters the compressor with lower pressure and temperature.

The hot coil is part of the condenser that is responsible for transferring the refrigerant to the edges of the refrigerator compartment. Its purpose is to use the heat from the refrigerant to keep the door seals of the refrigerator warm.
