Abstract

The increasing of people population and vehicle number in big city has caused lack of parking space. This condition has forced the architects to design some parking spaces in form of parking building i.e., underground parking garage. However, an underground a parking garage is having higher risk to the health due to the possibility of hazardous gases trapped inside the room. In a cold start condition, a motorized vehicle will emit higher concentration of hazardous compounds particularly for parameter of Carbon Monoxide (CO). So in this research, the authors aim to maintain, improve the Indoor Air Quality (IAQ) inside the enclosed parking garage by implementing low energy consumption method. Generally, the management of parking garage can operate one or more exhaust fans to create air circulation and remove the air pollutant out of the parking garage. This method works by diluting the air pollutants with the fresh air and decrease the pollutant concentration. However, this method needs more fresh air supply to prevent the accumulation of air pollutants trapped in the enclosed parking garage. In order to decrease the fresh air supply, it is need to short the path flow of the air pollutant. In order to short the path flow, the authors add a secondary exhaust fan near to the emission source (tailpipe of cars) which is integrated to the wheel stopper. Then, we evaluate the performance of the secondary exhaust fan in a simple enclosed parking garage which has maximum capacity of six cars. There are 6 (six) designs of secondary exhaust fan/wheel stopper proposed to remove the air pollutants. The selected is determined based on the uniformity of the air flow absorbed by each hole on the secondary exhaust fan. In the final stage of the study, we evaluate the effects of the secondary exhaust fan in decreasing the Indoor Air Pollution (IAP) inside the enclosed parking garage. The performance of each secondary exhaust fan design and the effects of the addition of secondary exhaust fan are evaluated by using Computation Fluid Dynamics (CFD). By combining the primary and the secondary exhaust fan, they create better air circulation inside the parking garage and maintain the CO concentration which is emitted by three idling cars. Based on the CFD simulations, the secondary exhaust fan can effectively reduce the indoor air pollution which caused by the emission of three idling cars. The CFD results also show that the increasing of flow rate of secondary exhaust fan will reduce the CO concentration inside the parking garage.
