三、波纹内沟槽管的传热性能本节将对外径5/8″波纹内沟槽管的传热性能作一介绍。每根样管的尺寸为5/8″×0.032″×14.8″(直径×壁厚×长度)。至于内螺旋沟槽管和波纹内沟槽管的壁厚则以平均壁厚计算。 (二)试验方法和条件试验部分为套管式,其外壳内径为21.8mm(0.86″)。试验部分连接在2.2kW的氟利昂制冷装置上。制冷剂R-22流过试验样管,而水流过试验样管与外壳间的环形部分。
Third, the corrugated pipe heat transfer performance This section will be outside diameter 5/8 “corrugated grooved pipe heat transfer performance to make an introduction of each sample size of 5/8” × 0.032 “× 14.8” (Diameter × wall thickness × length). As for the inner spiral groove pipe and corrugated groove pipe wall thickness is calculated as the average wall thickness. (B) Test Methods and Conditions The test section is a bushing with an inside diameter of 21.8 mm (0.86 ") and the test section is connected to a 2.2 kW freon refrigeration unit. The refrigerant R-22 flows through the test sample tube while the water flow Test the ring between the sample tube and the housing.
