层式通风下送风温差对室内热舒适性的影响

针对层式通风这一新型空调通风方式，以某一典型的空调办公室为研究对象，对不同的送风温差下办公室冬季室内环境的温度场、速度场进行了探索性实验测量。结果表明在满足规范规定的送风温差的前提下，大温差送风可以提高人体活动区的温度，降低人体活动区的风速，热舒适性更高。实验研究工作为层式通风在其他相同或类似房间气流组织的设计提供参考。

Influence of the Supply Air Temperature Difference on Indoor Thermal Comfort under Stratum Ventilation

In view of the new ventilation type under stratum ventilation, this paper chooses a typical office as the research object, through measuring the temperature field and velocity field of the winter office environmental, we can obtain the results that large supply air temperature difference can improve the temperature and reduce the wind speed of the human activity areas, under the premise of meeting the specification of supply air temperature difference. The experimental research work provides reference for the design of ventilation in the same or similar room air-flow.
