Research on interaction effect of thermal, light and acoustic environment on human comfort in waiting hall of high-speed railway station

People's feelings of comfort about the indoor environment are a comprehensive reflection of the interaction of various environmental factors. This paper focuses on the impact of the interaction of air temperature, illumination and sound pressure level on human environment comfort perception in the waiting hall of high-speed railway stations. However, it is necessary to consider waiting halls with different space scales, a relatively stable experimental environment state and combined experiments of different environmental factor variables under the same experimental conditions. To solve this problem, this study adopts the method of combining on-site measurement, environment simulation cabin and VR (virtual reality) technology to construct the experiment scheme. The experimental results of this study confirm the following points: (i) People prefer the medium-scale waiting hall space. (ii) In the warm indoor environment in winter, the thermal environment comfort perception evaluation increases with increasing of illumination. The thermal comfort evaluation score in the environment (1500 – 3000 Lx, 26 °C) is 6.94% higher than that in the environment (150 – 500 Lx, 26 °C). (iii) Light environment perception is affected by the interaction of air temperature and sound pressure level, and a warm environment will reduce people's light environment comfort. The light environment comfort perception evaluation is negatively correlated with the sound pressure level. (iv) The sound environment comfort is affected by the temperature. When the air temperature increases from 17 °C to 26 °C, the acoustic environment comfort evaluation score is reduced by 22.84%. • People prefer the medium-scale waiting hall space. • The low illuminance will reduce the thermal environment comfort in waiting hall. • The warm environment will reduce the light environment comfort in waiting hall. • The sound environment comfort is affected by the air temperature in waiting hall.
