Abstract:
Although water vapor is not typically thought of as an indoor contaminant, multizone indoor air quality (IAQ) modeling can be used to predict water vapor concentrations in each zone by applying mass balance equations that incorporate water vapor sources and sinks. However, very few attempts have been made to model water vapor with a multizone IAQ program and such modeling presents unique issues including the appropriateness of model assumptions, the adequacy of moisture storage and generation models, availability of input data, and metrics for analysis.
This paper describes measurements of humidity and other IAQ parameters in a single zone test house. Experiments included generation of water vapor with a humidifier during a variety of ambient conditions. Moisture storage and generation elements were then added to a previously validated airflow model of the building to evaluate the capability of the CONTAMW multizone IAQ model to predict indoor humidity levels.
