污水源热泵空调系统在实际工程中的应用

Application of sewage source heat pump system in a practical project

针对大连市某实际工程的设计和建设,提出了以城市污水作为热泵水源的污水源热泵方案,介绍了系统流程、水源条件、污水过滤等关键问题。对该方案与传统方案进行了经济性比较,结果显示,污水源热泵方案虽然初投资较高,但可以节省可观的能源,降低了空调系统的运行费用,环境效果显著。

Based on the design and construction of a real project in Dalian, the sewage source heat pump scheme is proposed, using municipal wastewater as the heat source. The pivotal problems, such as system flow circuit, water conditions and filtration measures, are introduced. Compared to traditional scheme, the initial investment of the proposed scheme would be higher, but the energy consumption and operating cost of the air-conditioning system could be noticeably decreased and the environment benefits are remarkable.
