【摘要】 以成都市晚霞养老机构为例，通过对其室内外颗粒物(PM_2.5和PM₁₀)、有害气体（总挥发性有机化合物TVOC,CO₂和甲醛）浓度及室内外温湿度的持续监测，明晰冬季养老机构的室内外环境质量现状，剖析空气温度（T_a）和相对湿度（RH）对室内外空气质量的影响。最后，从养老机构选址、庭院绿地布局、植物配置等方面入手，为养老机构的空气质量提升提出有针对性的优化措施。更多还原

【Abstract】 In winter, this study takes Sunset Glow nursing home in Chengdu as an example, through the continuous monitoring of indoor and outdoor particulate matter(PM_2.5 and PM₁₀), harmful gases（total volatile organic compounds TVOC, CO₂ and formaldehyde） concentration, indoor and outdoor temperature and humidity, to clarify the indoor and outdoor environmental quality status of the nursing home in winter. The effects of air temperature（T_a） and relative humidity（RH） on indoor and outdoor air quality were analyzed. Finally, starting from the site selection of pension institutions, green space layout of courtyards, plant allocation and other aspects, targeted optimization measures are proposed for the improvement of air quality of pension institutions.更多还原
