近年来国内外高温水采暖系统有很大的发展,系统加压方法也很多,但大部分加压方法的着眼点是使系统恒压在某一温度下的饱和压力,使系统密闭在某一定压下运行。系统加压的优劣直接影响高温水采暖系统安全运转和关系到高温水系统广泛应用和推广。结合我国和我区的技术经济条件,根据采暖系统的运行规律是随室外温度变化而变化的特点,就新疆整个采暖期一般90％以上
In recent years, high-temperature water heating systems have developed at home and abroad, and there are many methods for system pressure. However, most of the methods of pressurization focus on the saturation pressure of the system at a certain temperature and make the system tightly closed. Press to run. The pressure of the system directly affects the safe operation of the high-temperature water heating system and relates to the wide application and promotion of high-temperature water systems. Combining the technical and economic conditions in China and our region, according to the characteristics of the heating system’s operating law that changes with the outdoor temperature, it is generally over 90% of the entire heating period in Xinjiang.
