【摘要】 针对现有太阳能热水器系统浪费水资源的设计缺陷，在分析太阳能热水器水系统运行原理的基础上，采用通水输气两位阀替代传统的排气管及排气三通予以改进．系统结构简单，安装、维修方便，且能避免现行热水器顶水法淋浴时热水流失的弊端，使热能利用率显著提高，对节约水资源有重大意义．更多还原

【Abstract】 Basic Courses Department of ZILIA design defect of wasting water resources of the existing solar hot water heater is pointed out. On the basis of analyzing the water system’s working principles,two position water and vapour valve takes the place of the traditional exhaust pipe and exhaust three way valve.This will not only make the structure of the system simple,the installation and maintenance easy,but also avoid the shortcoming of loss of water when having a shower bath in the way of pushing up the water by using the existing solar hot water heater.It makes the utilization ratio of heat energy raise obviously,and has great significance of saving water resources.更多还原
