1 前言自然循环热水采暖,传统采用开式系统,这种系统循环的作用压头取决于散热中心和热源中心的高差及供、回水的温差,而这种系统的供水温度不能超过介质的饱和温度。为了增大该系统的循环作用压头,只有加大两个热中心的高度差,因此一般采用开式系统时,热源(热水炉)设在采暖建筑物地下室里,操作条件差(尤
1 Introduction Natural circulation of hot water heating, the traditional open system, the role of this system depends on the role of cycle head and heat center cooling center and for the backwater temperature difference, and the system of water temperature can not exceed the media The saturation temperature. In order to increase the cycle pressure head of the system, only increase the height difference between the two thermal centers, so generally open system, the heat source (water heater) is located in the basement of the heating building, operating conditions are poor
