大部分建筑服务工程师会遇到采暖或冷却系统管道出现的两种情况。一种是尽管采暖或冷却系统没有经过水处理,但系统仍然完美的运作;另一种情况是系统已经进行过水处理,但是却出现严重的腐蚀。为什么第二种情况的管道会如此的脆弱,另一个却不是这样?答案是常见的金属一般会受到腐蚀的威胁。腐蚀的速率和风险取决于多种因素。这包括了化学和微生物的生长环境、温度、水流量,还有更重要的因素是金属的厚度。水在建筑服务领域当中是非常理想的传热介质。它具有相当高的比热容,能
Most building service engineers encounter two conditions for the heating or cooling system piping. One is that although the heating or cooling system is not water-treated, the system still works perfectly; in the other case, the system is already water-treated, but it is subject to severe corrosion. Why the second case of the pipeline will be so fragile, the other is not the case? The answer is that the common metal is generally threatened with corrosion. The rate and risk of corrosion depends on many factors. This includes the chemical and microbial growth environment, temperature, water flow, and more importantly, the thickness of the metal. Water is a very good heat transfer medium in the field of building services. It has a very high specific heat capacity, can
