| With the public’s attention to sports and health,the indoor thermal environment of small and medium-sized gymnasiums has also been widely concerned by the public.At present,the indoor environment of the existing gymnasium in Guangzhou is mainly regulated by active equipment such as air conditioning,which causes great resource consumption and also has an impact on the physical health of the athletes.In addition,the types and time of national sports are diverse,and the preference and demand of people exercising in different seasons and in different intensities for thermal environment are also different.The transition season in Guangzhou is long,the climate is mild,and it is suitable for physical exercise.At this time,the use frequency of gymnasium is high,and the passive adjustment of thermal environment can achieve the best indoor comfortable effect.Therefore,based on the climatic characteristics of the transition season and winter,it is of great significance to study the passive regulation design to improve the indoor thermal environment of the stadium based on the expectation of the sports crowd to the environment.In this paper,the physical environment parameters of Guangdong Pharmaceutical University Gymnasium,a typical small and medium-sized gymnasium in Guangzhou,were collected in the transitional season and winter,and experiments were made to study the environmental expectations of sports people with three different exercise preference: low,medium and high.Through the comparative analysis of physical environment parameters and questionnaire survey results of the main and auxiliary pavilions,the indoor thermal environment of the main pavilions is evaluated.In the experiment,we know that in the transition season,the preferred temperature of the main hall under three sports intensity is:23.1℃,21.1℃,18.2℃,the preferred temperature of the auxiliary hall is: 24.6℃,21.8℃,20.8℃;In winter,the preferred temperature of the main hall is 18.6℃,14.8℃,13.7℃respectively,and the preferred temperature of the auxiliary hall is 16.9℃,13.6℃,12.4℃.With the increase of exercise intensity,the preferred temperature decreases gradually.In the main pavilion,the thermal environment is not good.In the transition season,the main pavilion feels hotter than the secondary pavilion.In winter,the main pavilion is colder than the secondary pavilion and the temperature difference between morning and evening is big.People who exercise are less receptive to environmental change;The demand for cooling is strong in the transitional season,and there is still a demand for cooling in winter under high exercise intensity.Ambient wind speed and humidity are expected to increase during the transition season and winter.In view of the above problems,based on the design status and use situation,the design strategy for passive adjustment of outdoor cooling environment,natural ventilation and heat insulation of the outer protection structure in the transitional season of the stadium was put forward respectively,and the adjustment effect of outdoor cooling and natural ventilation was verified by software simulation.The results show that the combination of greening and water and the opening of the skylight and side Windows have the best effect on the adjustment of the thermal environment in the transitional season.Finally,combined with the optimization scheme,the passive design method of thermal environment regulation of the stadium was extracted and summarized,and some suggestions were put forward for the site design,architectural form and skin design of the stadium in Guangzhou. |
