摘要
针对江水源热泵结合常规冷却塔的复合系统,以江水水温、水位和建筑冷负荷动态变化特性和影响变化规律为基础,根据江水源热泵和常规冷却塔水冷冷水机组两种冷热源形式的能效对比,提出临界取水高差和临界温差的概念和计算方法,用以指导实际工况下江水源热泵的节能分析判断和复合式系统运行控制模式的确定。综合调峰作用和能效优先原则,研究得到重庆地区水源热泵与辅助系统负荷分配比例。
The hybrid system is a cost-effective and energy-efficient way which can maximize the advantages of each type of beating and cooling source and meet operational requirements timely. The hybrid river water source heat pump with cooling tower system was studied. Based on the dynamic characteristics and influencing principles of river water temperature, water height and the building cooling load, the concepts of the critical river water taking eleva- tion and the critical temperature difference was presented by comparing the energy efficiencies between the fiver wa- ter heat pump system and the conventional cooling tower system. It is a key to evaluate the energy saving effect of river water source heat pump and determine the operating strategies of the hybrid system. Based on the river water condition and application situation in Chongqing, the load sharing capacity is analyzed considering the function of load shifting and the priority of optimal energy efficiency.
