Comparative study of simulation tools for multi-zone model

Making the directional airflows between zones is an efficacious measure to avoid contaminants threatening the health of people indoors and outdoors. Using the multi-zone model can predict the airflow in the whole building at the design phase, which can provide suggestions for actual engineering. At present, there are many tools to implement multi-zone simulation. The simulation tools are divided into traditional multi-zone simulation tools and multi-domain integration simulation tools, and they are summarized and compared in this study. The results show that the latter inherits and develops the multi-zone model of the former, and can simulate a more realistic ventilation system. In addition, because of its scalability, the latter can be applied to widely research fields. Therefore, the multi-domain integration simulation tool is considered to be a suitable multi-zone simulation tool in the future in this study.
