Experiment Research on the Effect of Indoor Temperature and Humidity Variation on Indoor Formaldehyde Concentration

Indoor environment is attracting more and more attention.Formaldehyde as a typical indoor pollutant especially endangers occupants'health.Indoor formaldehyde concentration is closely related to indoor temperature and humidity.The experiment results show that when indoor temperature or humidity alone rises,formaldehyde concentration accordingly in creases exponentially.Simultaneous increase of temperature and humidity makes greater conrtibutions to the increase of formaldehyde concentration.Therefore,indoor temperature and humidity should be kept as low as possible in the range of thermal comfort.
