摘　　要：通过分析天津地区典型年气象参数,将焓值和含湿量作为蒸发冷却空调系统适用性分区指标,采用试验和理论模型计算制冷季节间接蒸发冷却空调新风预冷系统逐时节能效果,研究间接蒸发冷却技术在天津地区的适用性。结果表明:天津地区适合采用间接蒸发冷却空调作为新风预冷装置,与机械制冷结合使用,以满足夏季空调需求;试验系统在制冷季全天运行工况下的季节总节能量为2 053.41 kW·h,总能耗为179.8 kW·h,平均COP为11.42;间接蒸发冷却技术用于新风预冷空调具有很大的节能潜力,并且能够降低制冷设备容量进而减少初投资。By analyzing the typical meteorological year parameters of Tianjin, the enthalpy and moisture content are used as the partition index for the adaptability of evaporative cooling air-conditioning systems. The experiments and theoretical models calculation are carried out to obtain the hourly energy-saving effect of the fresh air pre-cooling system of the indirect evaporative cooling air-conditioning in the cooling season, so as to study the adaptability of indirect evaporative cooling technology in Tianjin area. The results show that the indirect evaporative cooling air-conditioning is appropriate to be used as fresh air pre-cooling equipment in Tianjin, combining with mechanical refrigeration to meet the needs of air-conditioning in summer. The seasonal total energy-saving capacity of the experimental system under 24 hour operation condition is 2 053.41 kW·h, the total energy consumption is 179.8 kW·h, the average COP is 11.42. The indirect evaporative cooling technology has great energy-saving potential for fresh air pre-cooling air-conditioning, and can reduce the capacity of refrigeration equipment and reduce initial investment.
