饱和指数和稳定指数计算方法研究

摘要

In the process of handling central air conditioning recirculated cooling water, control and improvement fluid matter need to control the Ca2+ densities, saturated pH (pHs) , alkalinity, saturation index Is and stability index S in circulating water and their relation, but saturation index and stability index usually from check chart, because of check data and actual circumstance of chart to usually exist bigger deviation under the influence of factors, such as season, temperature and degree of humidity etc., therefore, for the sake of better carry on circularly cooling water of processing, decrease or defer decay, knot creations such as dirt and living creature dirty mark etc., this.text carries on a calculation through the number that handles to international hotel central air conditioning circulating water and finds out the number of saturation index and stability index calculation formula, a kind of number computes method that is simple, fast and accurate but doesni need to check chart is provided for circulating cooling water processing.%中央空调循环冷却水处理过程中，控制和改善水质需要掌握循环水中Ca^2＋浓度、饱和pH（pH8）、碱度、饱和指数Is和稳定指数S及其之间的关系，而饱和指数Is和稳定指数S通常由查阅图表得出，由于受季节、温度、湿度等因素的影响，查阅图表得到的数据与实际情况往往存在较大的偏差。因此，为了更好地进行循环冷却水处理，减少或延缓腐蚀、结垢及生物污垢等产生，本文通过对国际饭店中央空调循环水处理数据进行计算，找出了饱和指数Is和稳定指数S的计算公式，为循环冷却水处理提供了一种不用查阅图表，且简便快捷准确的数值计算方法。
