摘要： 结合工程实例，对渗滤取水技术在海水源热泵系统中应用的技术和经济性进行了探讨，结果显示，渗滤取水系统能为热泵系统提供水质好且夏季水温较低和冬季水温较高的海水；采用渗滤取水系统的海水源热泵空调系统无论在初投资还是运行费用上都优于直接利用地表海水的海水源热泵空调系统和传统的冷水机组加城市热网系统。 关键词 ：渗滤取水 海水源热泵 水温 经济性分析 Application of infiltration intake technology to seawater-source heat pump systems By Wu Junhua★, You Shijun, Yu Zhi and Li Haishan Abstract With a project example, analyses the technical and economic performance of this system. The results show that the infiltration intake system can provide the seawater with better water quality and lower water temperature in summer or higher water temperature in winter, and that the seawater-source heat pump (SWHP) air conditioning system with the infiltration intake system is prior to the SWHP air conditioning system direct using surface seawater and conventional chiller plus municipal heat network system in both initial investment and operation costs.
