Study on Indoor Thermal Comfort of Waiting Hall of Passenger Station in Desert Area in Summer

In order to grasp the thermal comfort of waiting halls of highway passenger stations in desert areas in summer, this paper selects a typical highway passenger station in the desert area of Xinjiang as the research object, and firstly carries out a one-week test and questionnaire survey on the thermal environment in the hottest month of the summer, and then proposes a method of estimating the average value of the thermal expectation factor e based on the theoretical formula of PMVe, and at the same time establishes the PMV and PMVe thermal comfort evaluation models, and both of them were compared with the MTS model for validation and analysis, respectively. The results showed that under the natural ventilation conditions in summer, the indoor temperature of the waiting halls varied less, and the indoor values of each temperature and humidity measurement point showed significant differences by the influence of the dry and hot outdoor air, with the maximum temperature and humidity differences of 1.33 ℃ and 7.08%, respectively; among the people with different origins, age groups and waiting times, the people who had a better acclimatization to the indoor thermal environment of the waiting halls in summer in the desert region were respectively: Southlanders, teenagers (13–17 years old), elderly people (60 years old and above) and people with a waiting time of 10 min or less; e was calculated to be 0.5513 by the method of estimating the mean value of the thermal expectancy factor e, and the results of the model validation showed that, compared with the difference of 0.75 for the PMV and the MTS, the differences between the PMVe and the MTS in the effective summer temperature range of the waiting halls ranged from 0 to 0.37.
