摘　　要：为了解决工程中常因双水箱太阳能热水系统的设计不当造成的水箱溢水等问题,论文基于强制循环式双水箱太阳能热水系统,通过分析研究系统运行中双水箱的水位变化,给出了两水箱间可能出现的最大水位差与连通管管径之间的函数关系。同时,对应用示例的计算与分析,给出了相应的预留空间大小、连接管管径以及各相关管口的高度位置。本研究对于工程上设计确定双水箱预留空间大小、连通管管径、各相关管口的高度位置具有理论指导意义。In order to solve the problem of overflow and other issues in tanks resulting from improper de- sign of dual - tank solar water heating systems, the article, based on forced circulation dual - tank solar water heating system, where a function is given about the relation between the maximum possible difference of the water level in dual water tanks and pipe diameter through the analysis of the change of water level in system operation. Meanwhile, with an example calculated and analyzed, the size of the reserved space, the connecting pipe diameter and the height positions of openings of the related pipes are offered. For determining the size of the dual - tank reserved space, the diameter of the connecting pipe and the height positions of openings of the related pipes have theoretical guiding significance in engineering design.
