Progress Toward a General Analytical Method for Predicting Indoor Air Pollution in Buildings: Indoor Air Quality Modeling Phase 3 Report

摘要

The interim report presents the results of Phase III of the National Bureau of Standards General Indoor Air Pollution Concentration Model Project. It describes: (a) a general element-assembly formulation of multi-zone contaminant dispersal analysis theory that provides a general framework for the development of detailed (element) models of mass transport phenomena that may affect contaminant dispersal in buildings; (b) an approach to modeling the dispersal of interactive contaminants involving contaminant mass transport phenomena; (c) an approach to modeling the details of contaminant dispersal driven by convection-diffusion processes in one-dimensional flow situations (e.g., HVAC ductwork); and (d) the features and use of CONTAM87, a program that provides a computational implementation of the theory and methods discussed. Equations governing contaminant dispersal in the whole building air flow system due to air flow and reaction or sorption mass transport phenomena are formulated by assembling element equations, that characterize a specific instance of mass transport in the building air flow system.
