Field measurement of indoor environment of underground garage in winter and analysis of its influence on people

Since the National Fitness has become a national strategy, people’s enthusiasm for fitness has also been increasing. When winter comes, the outdoor temperature becomes unsuitable for people to carry out exercise activities. Therefore, more community residents choose underground garages as a place for fitness activities. Due to the frequently entry and exit of vehicles and ventilation restrictions in the underground garage, whether the internal air quality in an underground garage meets the requirements of personnel activities remains to be studied. In this study, an underground garage in a residential area of Jinan was tested. The parameters involved CO2, CO, PM2.5, temperature and relative humidity. Select areas where people often gather for measurement. According to the test results, the distribution of CO2, CO, PM2.5, temperature and relative humidity in the underground garage were quantitatively analyzed. It is found that the air quality in some areas of the underground garage is poor, and long-term activities in this environment will affect people’s health. To solve this problem, in this study, the area with relatively good air quality in the underground garage is found to provide personnel activities, and the optimization measu.res of winter ventilation in the underground garage were put forward
