分析了机场地面专用空调设备的使用特点及其与单元式空气调节机、直接蒸发式全新风空气处理机组等普通空调设备相比的区别。指出由于没有统一的制冷试验工况标准,机场地面专用空调设备的设计、考核评价等存在混乱现象。参考国内外民用、军用相关标准及气象统计资料,建议机场地面专用空调设备的制冷额定试验工况参数取干球温度35℃、湿球温度28℃,民用设备最大制冷负荷试验工况参数取干球温度46℃、湿球温度30℃,军用设备最大制冷负荷试验工况参数取干球温度50℃、湿球温度33℃。
The characteristics of air conditioners used in airport ground are analyzed and compared with those of ordinary air conditioners such as unit air conditioners and direct evaporative air conditioners. It is pointed out that there is chaos in the design, assessment and evaluation of air conditioners for airport ground because there is no uniform standard for refrigeration test. According to civil and military standards at home and abroad, and meteorological statistics, it is suggested that the parameters of the refrigeration rated test conditions of air conditioners for airport ground should be taken as the dry-bulb temperature of 35 ℃ and wet-bulb temperature of 28 ℃. The parameters of the maximum refrigeration load test of civil equipment should be taken as dry The temperature of the ball is 46 ℃, the temperature of the wet ball is 30 ℃. The parameters of the maximum cooling load of the military equipment are the dry bulb temperature of 50 ℃ and the wet bulb temperature of 33 ℃.
