大空间建筑夏季喷口送风工况下室内空气垂直温度分布试验研究
Experimental study on vertical temperature distribution of indoor air in large space building under nozzle air supply condition in summer
摘要
Abstract
In order to study the vertical temperature distribution characteristics and its influencing factors of indoor air in a stratified air conditioning environment of large space buildings,the indoor temperature distribution of a large space building under different summer conditions is studied exper-imentally in this paper. Through the analysis of the influencing factors such as nozzle height, air supply volume and outdoor meteorological parameters, the characteristics of vertical temperature distribution and horizontal temperature distribution of indoor air are obtained. The results show that with the increase of the height of the nozzle and the volume of the air supply,the temperature layer increases,the vertical temperature distribution is not uniform, the large convection heat transfer is caused,and the horizontal temperature distribution tends to be uniform. There is a close correlation between the outdoor integrated temperature and the temperature and gradient of the non-air-condi-tioned zone. The research results in this paper can provide a reference for the airflow organization design of the nozzle air supply.关键词
