摘要 以送风状态点的干球温度、湿球温度及含湿量为基准，建立了蒸发冷却适用区域的6区模型，并以室内状态点的上限值作为送风状态点，分别以夏季空调室外设计参数、地下工程夏季空调设计参数、夏季空调干球温度及不满足200 h含湿量作为室外状态设计参数，计算并分析了各种形式的蒸发冷却系统在我国不同区域地下工程中的适用性，为蒸发冷却在地下工程中的应用提供基本设计依据。 关键词 直接蒸发冷却 间接蒸发冷却 地下工程 气象分区 Applicability analysis of evaporative cooling system to underground engineering in different regions of China By Guo Xuesen, Han Xu, Zhou Senlin, Zhang Hua, Dou Wenping and Wang Ruihai Abstract Establishes a six-zone meteorological model of applicable regions for evaporative cooling systems based on dry bulb temperature, wet bulb temperature and humidity ratio at the state point of air supply. Taking the upper limits of indoor design parameters as the state point of air supply, taking the air conditioning outdoor design parameters in summer, underground engineering air conditioning outdoor design parameters in summer, air conditioning dry bulb temperature in summer and humidity ratio with unsatisfied 200 hours as outdoor design parameters respectively, analyses the applicability of evaporative cooling technology for underground engineering in different districts of China. Provides design basis for evaporative cooling technology applied to underground engineering.
