In this study, the effect of using a hybrid solar thermal-activated adsorption desalination system for brackish water is evaluated under the climatic conditions of the Brazilian semiarid region. The proposed theoretical model utilizes climatic data from the meteorological station in Campina Grande, PB, and adsorptive kinetics data of Fuji Davison RD 260 silica gel to predict the performance indices of the specific daily water production (SDWP), specific cooling power (SCP), and coefficient of performance (COP) performance coefficients over a characteristic day. The SDWP value of 6.26 m3/ton, SCP ranging from 50 to 300 W/kg, and an average COP of 0.5 were obtained, considering variations in global horizontal irradiance in the ACDS system and transient ambient temperature. It was observed that both the production of desalinated water and the refrigeration effect increase with the rise in daily solar irradiance. The variation in the number of solar collectors used in the system and their optimality, as well as the variation in the salinity index of the feed source, impacted the evaluated performance coefficients.

在这项研究中，在巴西半干旱地区的气候条件下评估了使用混合太阳能热激活吸附淡化系统处理苦咸水的效果。所提出的理论模型利用来自宾夕法尼亚州大坎皮纳气象站的气候数据和Fuji Davison RD 260硅胶的吸附动力学数据来预测比日产水量（SDWP）、比冷却功率（SCP）、和性能系数 (COP) 特征日的性能系数。考虑到ACDS系统中全球水平辐照度的变化和瞬态环境温度，获得了SDWP值为6.26 m3/ton，SCP范围为50至300 W/kg，平均COP为0.5。据观察，淡化水的产量和制冷效果都随着每日太阳辐照度的增加而增加。系统中使用的太阳能集热器数量及其最优性的变化，以及供给源盐度指数的变化，都会影响评估的性能系数。
