摘　　要：深埋地下工程的地层温度比较低,导致其室内的平均辐射温度偏低,传统空调参数不能满足工作人员的需要。本文以Fanger热舒适方程及PMV-PPD评价指标为理论依据,采用Airpak软件对夏季南京某深埋地下工程房间的室内热环境情况进行了模拟。结果表明,平均辐射温度低于室内空气温度,室内相对湿度为60%时,最佳空气设计温度为25.7℃。Stratum temperature of deep underground engineering is low, thus its indoor mean radiate temperature is low too. And the traditional air conditioning parameters can＇t reach the thermal eomfort＇s requirement. Then a deep underground air-conditioning room＇s thermal environment in Nanjing in summer was simulated by Airpak based on the Fanger thermal comfort equation and PMV-PPD. The results showed that the mean radiate temperature is lower than the indoor air temperature and the best design temperature was 25.7℃ when the RH was 60%.
