摘要
本文基于人体散热平衡的理论,建立了非稳态环境下在夏季和冬季空调房间预测人体冷热感受的评价方法。在冷热感模型的基础上,结合红外传感器和室内环境参数关联算法获取用户体表参数及周围的环境参数,预测空调房间内人员的冷热感觉,控制空调的温度、风速大小和方向,自动使用户达到舒适状态。实验结果表明:通过采用冷热感技术的空调自动调节,在开机50min后,制冷和制热工况下,用户冷热感在舒适偏凉到舒适偏暖之间的比例分别为92%和94%,达到了用户手动调节的水平。
Based on the theory of human body heat balance, an evaluation method of predicting the thermal sensation of human body in air-conditioned rooms in summer and winter under unstable environment was established. On the basis of thermal sensation model,the infrared sensor and the indoor environment parameter correlation algorithm were used to obtain the parameters of the user’s surface and the surrounding environmental parameters which then adopted to predict the users’ thermal sensations in air-conditioned rooms. The temperature, wind speed and direction of the air conditioner were controlled automatically, realizing a comfortable state for users. The experimental results showed that the users’ proportion of thermal sensation from slightly cool to slightly warm was 92 % and 94 % respectively in refrigeration conditions and heating conditions after the conditioning operated for 50 minutes by using the thermal sensation technology, which achieved the same level through manual adjustment.
