An evaporatively-cooled façade system, composed of a Photovoltaic thermal (PVT), evaporative cooler, and evaporatively-cooled façade, was previously developed. In this study, a control algorithm for the system parameters is implemented and applied on spaces with evaporatively-cooled façade to generate the least possible façade temperature, and consequently maximum possible energy savings. The optimization of the system parameters is expected to overcome the limitations of using evaporative coolers in humid countries. The application of the control algorithm managed to increase the reductions in the façade heat gain from 33.5% to 38.3%.

The system, integrated with the control algorithm, is then applied throughout the year on spaces located in Doha (Qatar) and Riyadh (Saudi Arabia), mimicking cities with harshly hot humid and dry weather conditions, respectively. The daily and monthly performances are further investigated in four different space orientations (i.e., north, east, south, and west). It was found that the application of the system can halve the highly glazed façade heat gain during the summer, in all orientations, and may have adverse, yet desirable effect during the winter. The integration of the control algorithm managed to reduce differences in system performance between dry and humid locations, thus generating total annual savings of up to 21.8% in any typical city of the Arabian Gulf.

以前已经开发了一种蒸发冷却的立面系统，该系统由光伏热（PVT），蒸发冷却器和蒸发冷却的立面组成。在这项研究中，针对系统参数的控制算法被实现并应用于带有蒸发冷却立面的空间，以产生最低可能的立面温度，从而最大程度地节省能源。系统参数的优化有望克服在潮湿国家使用蒸发冷却器的局限性。控制算法的应用设法使立面热增益的减少量从33.5％增加到38.3％。

该系统与控制算法集成在一起，然后全年用于位于多哈（卡塔尔）和利雅得（沙特阿拉伯）的空间，分别模仿酷热潮湿和干燥天气条件的城市。在四个不同的空间方向（即北，东，南和西）上进一步研究了每日和每月的表演。已经发现，在夏季，该系统的应用可以使各个方向的高玻璃幕墙热量减少一半，并且在冬季可能会产生不利而又理想的效果。控制算法的集成设法减少了干燥和潮湿位置之间系统性能的差异，因此，在阿拉伯海湾的任何典型城市中，每年最多可节省21.8％的总费用。
