| Abstract: | 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. |
