| Summary: | The chassis dynamometer room in the automotive laboratory UTHM is one of very few chassis dynamometer room available in Malaysia. Therefore, it is considered as a one of rare facilities for test concerning engine performances, fuel consumptions and exhaust emissions. SIRIM for instance, needs the equipment for experiments on new invented biodiesels. The room is already equipped by a ventilation system, but unfortunately this existing system is not sufficient to support activities conducted in the room, as high temperature and accumulated smoke in the room are obviously observed. Hence, the person in charge has to depend on natural ventilation which is windows and doors opening. However, the problem is still occurring. Therefore, health and comfort issues are crucial. Furthermore, reliability of the chassis dynamometer test results could be questioned due to the instability of temperatures and relative humidity in the room during experiments. In order to obtain good results both temperature and relative humidity in chassis dynamometer room shall be maintained at certain constant values during testing. In the present work the Indoor Air Quality (IAQ) in the chassis dynamometer room is has been proved to be poor, leading to hazardous and uncomfortable working environment. Thus, the development of an improved ventilation system is essential. Therefore, the present study is carried out to determine the ventilation rate and heat load needed for the chassis dynamometer room. From the results, the undersized existing ventilation system is of evident. |
