Abstract :
Accounting into the differences of heat load of the sewage emission and heat demand of the building, it is not able to satisfy the heating user only by the limited temperature difference sensible heat in many small trunk canals, a new heat pump system named urban sewage source heat pump system with freezing latent heat collection is proposed. In this system, the freezing latent heat is used as the heating source of the heat pump at peak heat load in winter as well as the sensible heat. Then the problem of the system design becomes one important issue, with the annual cost value as an evaluation criterion, it was optimized on the system design. The result shows that the new heat pump system is superior in the economy than the traditional chiller and heating network system.
