摘要:
为了研究大空间建筑在分层空调环境下的室内空气垂直温度分布特性及其影响因素,该文对某大空间建筑在夏季工况不同喷口送风下的室内温度进行了试验测试。通过对喷口高度、送风量、室外综合温度等参数的分析,获得了室内空气垂直和水平温度场分布特性。研究结果表明,喷口高度和送风量的增加会引起温度分层面升高和垂直温度分布不均匀,且导致较大的对流转移热负荷,但水平温度分布趋于均匀; 室外综合温度与非空调区的温度及梯度密切相关。该文研究结果可为喷口送风的气流组织设计提供参考。
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 experimentally 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-conditioned zone. The research results in this paper can provide a reference for the airflow organization design of the nozzle air supply.
