群体热感觉模糊综合评判方法研究

Comprehensive fuzzy evaluation method of group thermal sensation

为计算室内热环境控制区域内多名用户的群体热感觉,以实现基于人体热感觉穿戴传感的室内环境优化控制,提出了群体热感觉模糊综合评判方法。为验证该方法的有效性和适用性,进行了不同人数模式下的试验研究,结果证明利用该方法计算的群体热感觉能够有效平衡个性化热感觉的差异性,代表所有用户的群体热舒适性。根据综合评判误差,对不同综合评判算子在不同用户人数和不同热感觉权重比例下的综合评判结果进行了优劣排序,指出了不同评判算子在不同场景下的适用性。

In order to calculate the group thermal sensation of multiple users in the control area of building thermal environment and realize the indoor environment optimization control based on wearable sensing of human thermal sensation,proposes a comprehensive fuzzy evaluation method of group thermal sensation.To verify the effectiveness and applicability of this method,carries out the experimental studies in the laboratory under different number modes.The results prove that the group thermal sensation obtained by this method can effectively balance the difference of personalized thermal sensation and represent the group thermal comfort of all users.According to the comprehensive evaluation error,ranks the results of different comprehensive evaluation operators at different user numbers and different thermal sensation weight ratios^and points out the adaptability of different evaluation operators under different scenarios.
