Study on the Influence Law of Indoor Temperature Conditions on Formaldehyde Diffusion: A Case Study of a Residential Building in China

With the improvement of people’s living, learning and working environments, the requirements for indoor air quality in buildings are getting higher and higher. People begin to pay attention to various indoor environmental qualities, because these qualities directly affect people’s physical and mental health and the efficiency of work and study. Among them, the concentration diffusion of formaldehyde is the most important influencing factor. This thesis explores the change rule of formaldehyde diffusion rate and the change rule of formaldehyde concentration under different temperature conditions, taking the indoor of a building residence in Huangdao District, Qingdao City, as the research object, and numerical simulation and analysis of it by using Airpak software, which allows users to check the diffusion law of formaldehyde with the temperature boundary conditions in a visualized contour manner, and provides the results to guarantee the improvement of the quality of indoor air to protect the occupants’ safety and health.
