摘　　要：论述了太阳能及海水能作为空调系统冷热源的可行性及二者结合的必要性,分析了集中式和分散式两种太阳能-海水源热泵系统的构成形式和特点.设计了一种利用太阳能-海水源热泵通过空调系统进行冬季供暖与夏季供冷的方案,讨论了系统方案中两种低位热源交替供暖或供冷和同时供暖的多种运行方式.能效分析表明,夏季利用海水能可使制冷机组的制冷效率显著提高,约为现有空气源制冷装置的1.8倍;冬季采用太阳能-海水源热泵,与传统供热方式相比可节省约2/3左右的电能,同时减少了二氧化碳排放.The feasibility of using solar energy and seawater respectively as the cold and heat sources for air-conditioning systems was discussed.The structure form and characteristics of the centralized and decentralized systems were analyzed.A heat pump system was presented,and its operating modes of cooling in summer and heating in winter were studied.The solutions and different operation modes utilizing the two low-level energy resources,the solar energy and seawater energy alternately to provide heating and cooling,or utilizing both of them to provide heating,were discussed.The results show that,when running under refrigeration pattern using summer seawater energy,the proposed system can reach very high refrigeration coefficient,about 1.8 times of the existing air-source units,and when running under heating pattern in winter,the system has the potential of saving 2/3 or more electric power compared with the traditional heating units.Moreover,the system has good environmental performance,reflected mainly in the reduced emission of carbon dioxide.
