污水源热泵的污水子系统是一个旁路串联水泵系统,基于实际工程数据的数值实验,提出了小阻抗旁路串联水泵的环路独立性原理,分析了系统流量的运行稳定性和调节性,论证了双级水泵的技术可行性,并给出了水泵的选择要点和系统调试方法,为污水源热泵系统的工程设计提供理论依据。
The sewage subsystem of sewage source heat- pump is pumps in pass- by series model. Through the numerical experiment using the actual engineering data, the principle of loop independence was established. The stability and adjustability of the subsystem were discussed and the technical feasibility was also confirmed. The points of pumps selection and the methods of system debugging were given out,and it offered reference for sewage source heat- pump project design.
