摘要(Abstract):
分析国内外海水热泵的应用现状,阐述了海水热泵的工作原理,研究海水热泵推广应用的难点,讨论沿海火力发电厂应用海水热泵的优势和条件。对比分析溴化锂吸收式热泵和CO_2跨临界热泵的特性和优势,提出大型沿海火力发电厂应用CO_2跨临界海水热泵进行区域供热的总体设计思路,为海水热泵的推广应用提供依据和思路。
The application status of seawater heat pump both at home and abroad is analyzed, and the working principle of seawater heat pump is expounded; the difficulties in the popularization and application of seawater heat pump are studied, and the advantages and conditions for the application of seawater heat pump in coastal thermal power plant are discussed. The characteristics and advantages of lithium bromide absorption heat pump and CO_2 trans-critical heat pump are compared and analyzed, and the overall design idea of the modern large-scale coastal thermal power plant using CO_2 trans-critical seawater heat pump for regional heating is proposed, which provides the basis and ideas for the popularization and application of seawater heat pump.
