Abstract Air distribution is widely used for thermal comfort. Air distribution is inevitably non-uniform with some subzones in the occupied zone cooler than the others, and the thermal preferences of occupants are differentiated. Non-uniform air distribution may deteriorate thermal comfort because occupants with warmer thermal preferences might sit in cooler subzones. This study proposes to utilize the non-uniformity of air distribution to improve the satisfaction of thermal preferences by coupling the thermal condition profile of air distribution and thermal preferences. Firstly, the thermal condition profile is characterized by ranking the thermal conditions of the subzones from cool to warm using possibility analysis. Secondly, the thermal condition profile and thermal preferences are coupled sequentially, and the thermal conditions of the subzones are controlled to be as close to the respective thermal preferences as possible. The sequential coupling of the thermal condition profile and thermal preferences takes advantage of the non-uniformity of air distribution and the active role of occupants in improving thermal comfort. Thus, with the proposed method, the occupants with warmer thermal preferences sit in the warmer subzones, and their differentiated thermal preferences are maximally satisfied by the non-uniformity in air distribution. Based on the experiments in a classroom served by stratum ventilation, the proposed method is validated by 100,000 cases with different cooling loads and thermal preferences. Compared with the previous method which ignores the matching between the thermal condition profile and thermal preferences, the proposed method improves the satisfaction of thermal preferences by 40.1% on average.

空气分布和热偏好的热条件剖面的耦合热舒适控制

摘要 空气分配被广泛用于热舒适。空气分布不可避免地不均匀，占用区域中的一些分区比其他分区更冷，并且占用者的热偏好是不同的。不均匀的空气分布可能会降低热舒适性，因为具有较高热偏好的居住者可能会坐在较冷的分区中。本研究建议利用空气分布的不均匀性，通过耦合空气分布的热条件剖面和热偏好来提高热偏好的满意度。首先，热条件剖面的特征在于使用可能性分析将子区域的热条件从冷到暖进行排序。其次，热条件剖面和热偏好依次耦合，并且子区的热条件被控制为尽可能接近各自的热偏好。热条件剖面和热偏好的顺序耦合利用了空气分布的不均匀性和居住者在提高热舒适性方面的积极作用。因此，使用所提出的方法，具有较暖热偏好的居住者坐在较暖的分区中，并且空气分布的不均匀性最大限度地满足了他们差异化的热偏好。基于在由地层通风服务的教室中进行的实验，所提出的方法通过具有不同冷却负载和热偏好的 100,000 个案例进行验证。与之前忽略热条件剖面和热偏好之间匹配的方法相比，
