摘要:

提出了基于房间用户热感觉的室内热环境控制方法,为比较其与基于温度设定值的室内热环境控制方法的优劣,搭建了基于热感觉控制的实验台。通过实验对比了2种控制方法在供冷运行条件下,室内热环境控制效果、用户满意度、用户工作效率和空调系统能耗的差异。实验结果显示,2种控制方法在用户满意度和用户工作效率方面没有统计意义上的显著差异。但基于热感觉的控制却能实现更稳定的室内热环境,对于安装分体空调、内有10个左右用户的办公用房间来说,基于热感觉的控制比基于温度设定值的控制减少空调系统能耗15.3%

Abstract:

Proposes an indoor thermal environment control methodology based on thermal sensation. In order to compare the differences of indoor thermal environment control between thermal sensation and temperature set point value, establishes a test-bed and conducts a series of experiments to compare their control performances, user satisfaction, productivity and system energy consumption in the cooling operation. The comparison results show that both of the two control methods can achieve similar user satisfaction and productivity without statistically significant difference. However, the thermal sensation based control can achieve more stable thermal environment. Further, for the office room with about ten occupants and equipped with split air conditioners, the thermal sensation based control consumes 15.3% less energy than temperature set point based control.
