Analysis of Indoor Inhalable Particle Concentration under Variable Air Volume Air Conditioning System

In order to study the factors of influencing indoor particle concentration under the variable air volume air conditioning system, utilizing the law of mass conversion establish unsteady model on indoor particulate matter concentrations. As the inhalable particle for researchful object(particle diameter is less than or equal to ten micrometer), analyze the influence factors on indoor inhalable particle concentration theoretically on the basis of unsteady model, such as the indoor residual heat, indoor moisture load, outdoor inhalable particle concentration and initial concentration of indoor inhalable particle and obtaining the variable relationships about different factors and indoor inhalable particle concentration. Results indicate that, by controlling some relevant factors reasonably can reach for the purpose of reducing indoor particle concentration. Therefore, the unsteady model can provide some theoretical basis on lowering indoor particle concentration and improving indoor air quality.
