摘　　要：在传统风洞风速模拟与控制实验技术基础上,通过增加太阳辐射模拟和空气温湿度控制,初步实现对室外自然气候中太阳辐射,风速及温、湿度环境的模拟控制。经过对可视化程序设计的风洞环境测控系统的调试,风洞内4个参数(辐射照度、风速、温度和湿度)各指令值与模拟值的平均偏差分别为-0.6%、+2.9%、+0.7%和- 0.7%,此风洞实验台可以用于含湿建筑材料太阳能被动蒸发降温问题的研究。Hot-humid climatic wind tunnel （HCWT）was introduced for simulate above natural climate environmental elements according to the variant velocity of flow and simulated solar radiant intensity regulation. A performance debug of the environmental measurement and control system was carried out and difference between instructions and simulations were - 0.6%, ＋ 2.9%, ＋ 0.7%, - 0.7% for solar radiation,air velocity,temperature and humidity,respectively. The Hot- humid climatic wind tunnel was adapted to the study of passive evaporation cooling effect of porous materials.
