水电站专用空调系统节能研究
Energy saving research of dedicated hydroelectric air conditioning system for hydropower station
摘要:
该系统利用水电站的深层水库水作为冷源或热源,具备过渡季节和冬季自然冷却、夏季制冷、夏季新风预冷和冬季供暖四种节能运行模式。介绍了该系统的工作原理及技术要点,分析了系统的节能效果,并介绍了三峡工程的节能改造效益。与水电站传统采用的风冷主机加末端或普通冷却塔冷却式水冷冷水机组加末端的集中空调系统相比,该系统的环境适应性更强,能效比更高,运行稳定。
Abstract:
The system applies the deep layer reservoir water as cold and heat source, which has four energy saving operation modes including free cooling mode both in the transition season and in winter, the refrigeration mode in summer, the precooling mode for fresh air in summer and the heating mode in winter. Presents the operation principle and technical points, and analyses its energy saving effect. Presents the reconstruction benefits of Three Gorges Project. Compared with conventional central air conditioning system, such as the combination of air-cooled chiller (heat pump) and terminal unit or the combination of water-cooled chiller and terminal unit, the system is superior in flexibility, energy efficiency rate and operation stability.
