A stratum ventilated heating system is applied to satisfy the thermal requirements in a sleeping environment. Several parameters and configurations significantly influence the performance of the heating system. Among these parameters, the supply vane angle, supply air terminal, and exhaust location are critical factors that influence the energy consumption, indoor air quality, and thermal comfort level, and show no direct energy consumption character itself. However, it is difficult to achieve an effective trade-off between these parameters. This study aims to determine a suitable vane angle and height of the air supply and an appropriate exhaust location to achieve the best performance based on the technique for order preferences by similarity to an ideal solution (TOPSIS) method. The optimal parameters are a supply vane angle of 30° and a supply height of 800 mm. For Version 1, the mean age of air (MAA), room-air change efficiency (RACE), occupied-zone-air change efficiency (BACE), energy utilization coefficient (EUC), and whole percent dissatisfied (WPD) were 386.5, 0.546, 0.806, 1.12, and 4.6, respectively. The corresponding values for Version 2 were 436.1, 0.546, 0.790, 1.291, and 4.58. Therefore, the stratum ventilated heating achieves a trade-off between indoor air quality, energy savings, and thermal comfort using the TOPSIS method.

应用分层通风的加热系统以满足睡眠环境中的热量需求。几个参数和配置会严重影响加热系统的性能。在这些参数中，送风叶片角度，送风终端和排气位置是影响能耗，室内空气质量和热舒适水平的关键因素，并且本身没有直接的能耗特征。但是，很难在这些参数之间实现有效的折衷。这项研究的目的是根据与理想解决方案（TOPSIS）方法相似的订单偏好技术，确定合适的叶片角度和供气高度以及合适的排气位置，以实现最佳性能。最佳参数是供应叶片角度为30°，供应高度为800 mm。对于版本1，平均空气年龄（MAA），房间空气变化效率（RACE），占用区空气变化效率（BACE），能源利用系数（EUC）和整体不满意百分比（WPD）为386.5、0.546、0.806、1.12和4.6，分别。版本2的相应值为436.1、0.546、0.790、1.291和4.58。因此，使用TOPSIS方法，分层通风采暖可在室内空气质量，节能和热舒适性之间进行权衡。
