Design and develop an enhanced indoor air flow device via bubbles

Abstract

This project aims to improve the existing design of an air flow device so that the cooling process can be easily performed in the normal room condition. The previous project of the air flow device was focus on the performance testing of cooling process. Hence, a design modification of an enhanced air flow device is required in this project so that the final product can be applied into the office and household environment.

The cooling process for this enhanced air flow device requires water as the main cooling medium for the hot air inside the room. The design concept for the cooling process mainly consists of two parts: primary cooling for the hot air by the heat exchange in the water and secondary cooling for the warm air by the evaporation of the water bubbles.

Based on the design concept, a product prototype for this enhanced air flow device was made and a performance testing was conducted. According to the data and observation from the experiments, a detail analysis was explained and some of recommendations were suggested for developing the actual product.
