摘要： 从毛细管的微分方程模型出发,建立了绝热毛细管类比设计法的理论公式,提高了毛细管的设计效率.

关键词: 制冷装置, 类比法, 毛细管, 设计

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
