Numerical analysis of ventilation system performance by COMIS model
This research evaluated the performance of four kinds of ventilation systems for dwellings under various conditions by means of numerical simulation. The total number of combinations of various parameters for the calculation was 174. Calculations were performed hourly for indoor air pollutant concentration, humidity and condensation, indoor-outdoor pressure difference, airflow rate, and heat energy by ventilation, etc., through the heating season. A multizone infiltration and pollutant transport model (COMIS) was used to perform the simulation. A new term, acceptable ratio, is introduced in this study to evaluate the performance of ventilation systems from the point of view of CO{sub 2} level and energy consumption. In addition, by means of statistical methods, the effect of various factors on ventilation system performance is discussed. A set of predictive equations for ventilation systems are derived in this paper to try to evaluate ventilation system performance in an easy way under any conditions.
