Abstract:Temperature of urban sewage is suitable, but its flux is insufficient as cooling and heating source. So in many cases the conventional sewage source heat pump system is unable to satisfy the building heat peak load. According to this condition, a novel mentality is proposed about which the freezing latent heat of urban sewage is used as the low temperature heat source of heat pump in the building as well as sensible heat. Then the important equipment is developed, freezing latent heat exchanger namely, which can eliminate the ice safely, extract the heat continuously, remove the sewage soft-dirt, and strengthen heat transfer. According to the sewage characteristics, reasonable form of the urban sewage source heat pump with freezing latent heat collection is discussed and established. The results of analysis show that the new system has broad feasibility and giant application potential.
