Abstract: The capillary tube expansion device is widely used in the refrigerating and air-condition-ing equipment. The analogical method is one of the most popular design methods for capillary tubes. However, it is an empirical method. Based on the differential governing equations of an adi-abatic capillary tube, the theoretical formulation of the analogical design method has been devel-oped here. It is simple but helpful to engineers in improving designing efficiency.

Key words: capillary tube, design, analogical design method, refrigerating equipment
