本初步研究评估了在极端炎热和潮湿气候条件下，交流冷却应用中间接/直接蒸发冷却（IDEC）的整体能源性能。试点范围包括安装一台5吨的IDEC混合（串联）机组和一台现有的5吨常规DX机组，为位于沙特阿拉伯达兰的一栋房屋提供舒适的制冷。室内制冷需求由IDEC机组满足45%的制冷季小时数，而剩余的55%由DX机组满足。整个IDEC/DX混合动力系统的总加权年平均能效比（EER）为15.1，与仅在整个冷却季节使用DX机组相比，实现了26%的年节能。 根据室外干球空气温度记录了IDEC单位用水量，并观察到室外温度为66°F至108°F时，其特征范围分别为1.1 GPH至19.6 GPH。获得的结果为暖通空调界提供了更多关于极端炎热和潮湿气候下IDEC AC应用的机会和局限性的见解。引文:2016年3月14日至16日在科威特召开的第六届国际能源研究与开发会议

This pilot study evaluates the overall energy performance of indirect/direct evaporative cooling (IDEC) in AC cooling applications under extreme hot and humid climatic conditions. The pilot scope included the installation of a 5 ton, IDEC unit in hybrid (tandem) operation with an existing 5 ton conventional DX package unit to provide comfort cooling to a house located in Dhahran, Saudi Arabia. The house cooling demand was met by the IDEC unit 45% of the cooling season hours, while the remaining 55% were met by the DX package unit. The overall IDEC / DX hybrid system had a collective weighted annual average Energy Efficiency Ratio (EER) of 15.1, achieving 26% annual energy savings compared to using the DX package unit for the entire cooling season alone. The IDEC unit water usage was recorded as a function of the outdoor dry bulb air temperatures and was observed to have a signature range of 1.1 GPH to 19.6 GPH for outdoor temperatures of 66 °F to 108 °F respectively. Results obtained provide more insight to the HVAC community for the opportunities and limitations of the IDEC AC applications under extreme hot and humid climates.
