通过对人体模型测试和示踪气体测量 ,研究了一种个性化送风系统中风速、风温和污染物浓度随送风参数的变化状况 ,并预测了此系统微环境 (人员呼吸区 )中空气参数的改变程度。结果表明 ,个性化送风的灵活控制有助于改善局部热环境和空气品质 ,且呼吸区空气品质的改善程度与送风量、送风距离和人体周围的热羽流均紧密相关 By testing human body model and tracer gas measurement, the variation of wind speed, air temperature and pollutant concentration with air supply parameters in a personalized air supply system was studied and the air in this system micro-environment (personnel breathing area) was predicted The degree of change of parameters. The results show that the flexible control of personalized air supply can help to improve the local thermal environment and air quality, and the improvement of air quality in the breathing zone is closely related to the air supply, air supply distance and thermal plume around the human body
