摘　　要：研究蒸发冷却/辐射吊顶空调系统的节能问题.从理论上分析了蒸发冷却/辐射吊顶系统供冷时,房间外围护结构的内表面温度随其表面材料发射系数的变化情况,指出外围护结构内表面材料的发射系数是影响蒸发冷却/辐射吊顶空调房间节能性的重要因素.以西安地区某一高档办公室为例,分析了室内空气温度分别为24℃和26℃时,外围护结构内表面温度随发射系数ε的关系;得出当外围护结构内表面发射系数满足一定条件时,蒸发冷却/辐射吊顶空调系统要比传统空调系统节能,并且热舒适性相同.The evaporative cooling/cooling ceiling air conditioning system transfers heat by convection and radiant, however, traditional air conditioning system transfers heat mainly by convection to cool indoor air. So it is mainly analysed that the temperature condition on inner surface of the envelope in a room with the air conditioning system-evaporative cooling and cooling ceiling in the city of Xi'an with transfer heating theory,and it is pointed that absorption factor is a main factor that affects energy saving in a room with a evaporative cooling and cooling ceiling air conditioning system. Further it is given that it can operate with energy saving in the range of absorption factor values.
