The refrigerant capillary tube is a vital component to a refrigerator or air conditioner, because it condenses the amount of refrigerant supplied to the evaporator. As part of general procedure, Honeywell recommends initially charging the system with 85 percent by weight of the original charge. through the capillary tube with fall of temperature below the ambient, that may cause the undesired flow of heat from the ambient to the refrigerant inside the tube and reduces its heat extraction capacity from the refrigerating space and hence reduces the refrigeration effect. Insulate the probe with suction line insulation to prevent the element from being influenced by the surrounding air. These charts are for Fan Cooled units only.
