A tool for integrated simulation to evaluate the performance of ventilation system

To properly evaluate the performance of ventilation system, the interaction among ventilation rate, indoor air-quality, and cooling/heating load should be analyzed. In this study, an integrated simulation tool based on TRNSYS will be suggested to analyze the performance of ventilation system. Some modules to calculate the changes in indoor concentration of pollutants with ventilation system and to decide the operation mode of ventilation system were newly developed. In addition, the developed modules were coupled with building load and heating/cooling simulation modules. To verify the developed integrated simulation tool, the comparison study between simulation and field study were accomplished. The simulation tool developed in this study can be used to predict the performance of ventilation system with high accuracy.
