Abstract: From the ASHRAE Global Thermal Comfort Database II, several researchers in East and South Asia utilized personal and environmental variables to establish the thermal comfort model. Body temperatures at several locations were the most utilized personal input. The collected papers from 2003 to 2022 were utilized to analyze the progressive development of the thermal comfort model by using VOSviewer. The results indicate that scant research discusses the relationship between multiple physiological parameters and thermal comfort index under dynamic environments and neutral thermal comfort threshold. Therefore, this study establishes the physiological thermal comfort model under cold and hot environments for young subjects in Asia. The results indicate that people are more sensitive to cold stimulation than hot due to the cold sensors of human skin closing to the surface. The human temperature-regulated mechanism operates spontaneously to manage heat conservation and dissipation during cold/hot stimulation. During cold/hot stimulations, the neutral thermal comfort threshold of three physiological parameters adjusts with the level and properties of the stimulation. For the TSV models established by the single physiological parameter, the forehead skin temperature had a closer relationship with TSV than the other two parameters. However, the TSV model established by the multiple physiological parameters is the closest one to TSV among them all. This information could benefit air conditioner manufacturers and household occupancy decision makers to select a better controlling strategy for air conditioners for saving air-conditioning electricity but not sacrificing dwelling comfort.
