DESIGN OF COIL HEAT EXCHANGER FOR REMOTE-STORAGE SOLAR WATER HEATING SYSTEM

摘要：

A coil heat exchanger for hot water thermal storage was presented including the choice of the design parameters, thermal calculation, structural design and calculation of flow resistance. In this design, solar collector contour aperture area is 4.26 m2, the volume of water tank is 300L. The diameter and the coil heat transfer area of spiral coil heat exchanger are 460 mm and 1.48m2, respectively, which was made of φ15 mm×1 mm stainless steel tube, the total length of the coil is 31.8m. The calculation results showed that the thermal design fits the requirements of the hot water system.
