5.2了解系统中设备与材料的材质应确定或了解系统中设备、管道、阀门、水泵等所用材质，以适应设计工作对水质的要求及确定水处理方案，并防止系统腐蚀及结垢。5.3冷热水系统的水处理工艺热水供暖系统、空调冷热水系统的水处理方案，首先应采用先进技术及行之有效的方法---水处理自动加药设备对系统实行自动加药的化学水处理方法。单一采用钠离子交换器制取的软化水只防止系统结垢，不防止系统腐蚀，但空调冷、热水的腐蚀性大于自来水。这是由于，自来水中含有天然的碳酸氢钙，它是一种阴极性缓蚀剂。当自来水软化后，虽然提高了水的ph值，但是随着硬度成分的去除，水中原有的天然缓蚀剂--碳酸氢钙也被除去了；加之钠离子交换器的软化水比原水含盐量有所增加，其计算式为:
δg=2.95hca+10.84hmg式中δg—软化水含盐量的增加量,mg/l；hca—原水中ca硬度,mmol/l；hmg—原水中mg硬度,mmol/l。因此，单一采用钠离子交换器制取的软化水，还应投加化学药剂以阻止系统的腐蚀。这种方法既会使钠离子交换器产生大量再生废盐液而污染地下水，

又会使设备一次总比采用化学复合药剂方法的水处理设备大得多。不仅如此，采用与循环冷、热水系统特点相对应的化学药剂进行水处理，其运行费用也较低。它还是一种无污染的绿色环保产品，应大力推广。以物理方法进行水处理,如采用磁水器、电子水处理仪等装置，在某种水质的情况下有阻垢效果，但没有防止腐蚀的作用，因而会使系统发生严重的腐蚀。某商厦安装2台日立牌螺杆冷水机组，运行几年后发现设备、管道严重腐蚀，原物理水处理设备未能起作用。2002年初将原有的“电子水处理仪”及所有腐蚀管道全部拆除，拆除过程中发现管道内壁有大量锈瘤及氧化铁。因此对螺杆冷水机组也作了化学清洗。后改用“化学药剂方法”的水处理方案,采用自动加药设备,对空调冷热水系统及冷却水系统,均实施化学水处理，运行二年来收到了良好的效果。
