| 摘 要： | 污水源热泵系统的节能减排效益显著，污水的管内换热特性急需掌握。基于污垢热阻法建立光滑铜管管内污垢生长特性试验台，试验得出了人工污水颗粒状污垢管内的生长特性，并建立了其渐近型污垢积聚预测模型。试验发现，该人工污水在光滑铜管结垢的诱导期为21h，污垢热阻稳定时间为95h，稳定污垢热阻为1．5×10^-5m^2·K／W。

| Abstract: | The merits of the sewage source heat pump system are remarkable on energy efficiency and pollution reduction. Based on the fouling resistance law, the test bench was established on growth characteristics of fouling in copper pipe. The experiment has been carried on and the growth characteristics of fouling in copper pipe were obtained with the asymptotic agglomeration forecast model. It is found that the fouling induction period of the sewage is 21 hours in the smooth copper pipe, the fouling resistance settling time is 95 hours, and the stable fouling resistance is for ×10^-5m^2·K/W. |
