Abstract:

As a necessary part during sleeping, the bedding system has more pronounced effect on sleeping thermal comfort than the indoor environment. To properly evaluate the sleeping thermal comfort of the bedding system, commonly used evaluation methods were reviewed in terms of experimental research and numerical modeling studies worldwide. Based on the heat and moisture exchange theory of human-bedding system-environment system, various influencing factors for sleeping thermal comfort were analyzed in three aspects, i.e. bedding system factors such as thermal resistance, evaporative resistance and bedding microclimate, human body factors such as thermal physiological differences in gender and working status. Environmental factors such as environmental temperature, humidity and speed of wind were also investigated for their effects on the sleeping thermal comfort. The drawbacks of current studies were pointed out and the development trends of sleeping thermal comfort of bedding systems were predicted. A comprehensive ″human-bedding system-environment″ thermal comfort model was proposed to improve the accuracy of sleeping thermal comfort evaluation.

Key words: bedding system, sleep, thermal comfort, evaluation method
