摘要
以换热器中常见的污泥类颗粒污垢为研究对象,通过工程实例进行热阻实验,监测此类污垢在换热管内的生长情况,并建立热阻预测模型。对得到的实验数据进行分析,拟合出了适用于工程实际的污水换热器污垢曲线,对工程设计及污水源热泵系统的控制、运行都有指导意义。
Taking the sludge particle fouling as the research object, carries out the fouling thermal resistance experiment in an actual project, tests its growth and establishes a prediction model. Analyses the experimental data and obtains the fitting curve of fouling in sewage heat exchangers, which is recommended to be a instructive means in the design and control of the sewage heat pump system.
