Capillary tube is a thin copper tube, it uses its small inner diameter, length of the larger resistance along the length of the refrigerant to play the role of throttling pressure reduction. When the refrigerant flows through the capillary tube, due to the narrow pipeline, the flow rate increases, the pressure decreases, so that the refrigerant from the high-pressure liquid state into a mixture of low-pressure liquid and gaseous state, for the refrigerant in the evaporator evaporation and heat absorption to create the conditions.

1. Domestic refrigerators and freezersIn the refrigeration systems of refrigerators and freezers, the copper capillary tube fitting is the key throttling element. The refrigerant (e.g. R600a or R134a) flows out of the condenser and into the copper capillary tube fitting. Due to the small inner diameter of the capillary tube, the refrigerant flows faster in it and the pressure drops sharply. From the high-pressure liquid state into a low-pressure liquid and gas mixed state, and then into the evaporator. In the evaporator, the refrigerant absorbs heat to realize the cooling effect. For example, when we open the refrigerator door can feel the cold air, is through the capillary tube throttling pressure reduction after the refrigerant in the evaporator to absorb heat generated.

2. Domestic air-conditioning systemIn the household split air conditioning, capillary copper fittings also play a role in throttling down the pressure. It is located between the condenser and evaporator. Refrigerant (such as R410A) from the condenser of high temperature and high pressure state through the capillary tube, pressure and temperature reduction, into the evaporator. In the evaporator, the refrigerant evaporates and absorbs heat so that the indoor air is cooled when it passes through the surface of the evaporator to regulate the indoor temperature. Unlike a refrigerator, an air conditioner has a larger cooling capacity, so the size and length of the capillary tube will be adjusted according to the power of the air conditioner to ensure proper refrigerant flow and pressure drop.
