Recently, residents living in high-density residential zones have been ever increasing, with floor area ratios growing higher following the industrial development and the enhancement of our living standards. Consequently, there is an insufficient number parking spaces. In order to solve the lack of parking spaces an increasing number of underground parking lots are being constructed. Nowadays, jet fan ventilation systems utilizing the airflow induced by jet fans are being widely used for the ventilation of large areas such as underground parking lots and tunnels. The purpose of this actual study is to present a jet fan that is designed to reduce electric power consumption and carbon dioxide emissions through the enhancement of its performance. The airflow characteristics of a jet fan that is widely used for the ventilation of underground parking lots and large spaces were realized during the experiments performed in this study. In order to enhance the performance of the existing jet fan, alternative cases were fabricated and their airflow characteristics, etc. were measured. In addition, the power consumption for each case was also measured, thereby predicting the correct amount of carbon dioxide (CO2) emissions. Case 1 (inside guide type) presented as an alternative for the basic case was found to be the most superior type. It was considered to be more effective when reducing the power consumption and carbon dioxide emissions by approximately 30% in comparison to the basic case. It is thought that a better performance than that of an existing jet fan can be realized by simply replacing its nozzle part with a new one. |
