气候分析表明，在炎热干燥的气候中使用蒸发冷却具有巨大的潜力。本研究报告了一个案例研究，其中在爱达荷州博伊西的一个高性能教室中安装了多级蒸发冷却系统，作为唯一的夏季冷却系统。通过设计阶段的初步分析表明，与标准强制通风系统相比，仅安装的系统就足以提供大量节能的冷却。但课堂上教师和学生的现场反应表明情况并非如此。在设计阶段，实际性能和预期性能之间的差距非常大。本研究旨在通过入住后数据分析，找出安装的直接和间接蒸发冷却系统性能不佳的原因。通过安装的传感器系统收集了九个月的现场性能数据，包括室内外温度和相对湿度，以及直接和间接蒸发冷却系统内不同位置的温度。 通过各种数据分析来回答以下问题:（1）根据测量的温度和相对湿度，教室是否热舒适？（2） 多级蒸发冷却系统是否按设计运行？（3） 与类似气候下的类似系统相比，爱达荷州inBoise安装的蒸发冷却系统的性能如何？（4） 导致已安装系统性能不佳的潜在原因是什么？本案例研究旨在扩大对在炎热干燥气候下工作的蒸发冷却系统的一般理解，并为未来类似系统的设计提供有价值的反馈和指导。引文:美国丹佛市ASHRAE会议论文

Climate analysis has shown tremendous potential of using evaporative cooling in a hot and dry climate. This research reports a case study where amulti-stage evaporative cooling system is installed as the sole summer cooling system in a high performance classroom, located in Boise, Idaho.Initial analyses through design stages suggest that the installed system alone is sufficient to provide cooling with considerable energy savingscompared to a standard forced air system. But the field responses from instructors and students in the classroom indicate otherwise. The gapbetween the actual performance and the expected one at design stages is significant.This study aims to identify causes why the installed direct and indirect evaporative cooling systems underperform though post-occupancy dataanalysis. Nine months' worth of field performance data have been collected through the installed sensor systems, including indoor and outdoortemperatures and relative humidity, and temperatures at different positions within the direct and indirect evaporative cooling system. Various dataanalyses are conducted to answer the following questions: (1) is the classroom thermally comfortable based on measured temperature and relativehumidity? (2) is the multi-stage evaporative cooling system operated as designed? (3) how does the installed evaporative cooling system perform inBoise, Idaho as compared to similar systems under similar climate? (4) what are the potential causes that make the installed systemunderperform? This case study is intended to expand general understanding of evaporative cooling systems working in a hot and dry climate andprovide valuable feedback and guidelines for future design with a similar system.
