Abstract
- The evaluation of contaminant removal effectiveness can play a key role in a working environment quality investigation and in remediation efforts. In this study a computer simulation technique was developed for assessing the efficiency of contaminant removal within a partitioned working environment. To determine the effect of the physical parameters of each partitioned space on contaminant removal effectiveness, a relative contaminant concentration unit was used to show the simulation results. In addition, tracer gas techniques were adopted to validate the accuracy of the prediction model. A comparison of measured CO2 concentrations in a controlled environment chamber with the results of a simulation model is presented. This study investigated the partition configuration of work environment and environment parameters including openings operation, constant concentration, and exhaust air volume mode. Results indicated that variations of the above three parameters can produce great differences in overall ventilation performance. Through this type of study, the interaction of airflow and contaminant concentration between partitioned spaces can be understood in advance and adequate knowledge can be provided to maintain a high-quality and healthy environment for workers.
