摘　　要：提出了一种适宜极端热湿气候区岛礁环境资源特点的独立光伏驱动溶液除湿空调系统,并分析了原理和系统的流程。以1 000kW冷负荷为模块,建立了系统各部分的数学物理模型。分别在不同热湿比条件下对溶液除湿机组、室内空调末端和独立光伏系统进行匹配计算,得出了系统主要设备的规模优化组合关系,并对计算结果进行了分析。结果表明,总负荷一定时,热湿比越低,则除湿机组规模越大、室内末端和独立光伏系统规模越小、系统总能耗越低。因而独立光伏驱动溶液除湿空调系统更适用于热湿比低的建筑。Proposes a kind of stand-alone photovoltaic driven liquid desiccant air conditioning system which is suitable for the special environmental characteristics of extremely hot-humid islands, and analyses its principle and system process. Sets up a mathematical-physical model of each part of the system with the cooling load of 1 000 kW as example. Calculates the parameters of liquid desiccant units, air conditioning terminals and stand-alone photovoltaic system in the conditions of different values of angle scale, respectively, and obtains their optimal combination. The results show that when the total load is constant, the lower the angle scale, the larger the size of the desiccant unit, the smaller the size of the indoor terminal and the stand-alone photovoltaic system and the lower the total energy consumption of the system. Therefore, the stand-alone photovoltaic driven liquid desiccant air conditioning system is more suitable for the buildings with low angle scale.
