摘　　要：利用Airpak软件对比模拟了两种不同送风形式下地下工程大空间温湿度、风速及热舒适的热湿环境特征,结果表明:采用喷口和散流器送风形式,室内环境场和人员热舒适情况均能够得到一定保障。其中,散流器送风人员活动区域温度略低于喷口,空气龄较低约为212s,而喷口形式下的空气龄约为419s;喷口送风时室内平均温度略低为24.4℃,空间空气流动性更大,吹风感较强,中间区域风速达0.3-0.4m/s。对于空间大、人员密度高的地下空间,为保证人员区域环境更加舒适,从热湿环境角度考虑,采用散流器小风量形式能够更好地保障室内温湿度和风速环境场,并且室内PMV更加均匀,平均PMV为0.68,人员热感觉适中,能够实现整体人员不满意率低于25%。In this paper, we use Airpak to compare and simulate the indoor temperature, humidity and wind speed environmental of the underground centralized office hall under two different air supply forms. The results show that the indoor environmental field and personnel thermal comfort can be guaranteed by using the air supply form of ejector and air diffuser. Under the condition of diffuser air supply, the temperature in the activity area in the form of diffuser air supply is slightly lower than that of the ejector, and the air age is about 212s, while that of the ejector is about 419s. When use the air ejector supply, the indoor average temperature is slightly lower, which is 24.4℃, the air fluidity in the space is greater, the blowing feeling is strong, and the wind speed in the middle area is up to 0.3-0.4m/s. For the underground space with large space and high density of people, in order to ensure the more comfortable environment in the personnel area, considering the hot and humid environment, the small air volume of diffuser can better guarantee the indoor temperature, humidity and wind speed environment field. And the indoor Predicted Mean Vote(PMV) is more uniform, the average PMV is 0.68, and the people’s thermal sensation is moderate, which can realize that the Predicted Percentage Dissatisfied is less than 25%.
