The main objective of this study is to investigate the practicality of using ice as a cooling agent to improve the air cooling efficiency of a portable cooler by harnessing the latent heat of fusion. A portable air cooler has been fabricated utilising a commercially available polyurethane insulation box. The box has been integrated with a galvanised iron conduit, featuring a square cross section measuring 3 inches by 3 inches, to enable the flow of air. This tunnel efficiently separates the airflow from the ice, while still allowing thermal conduction between the ice and the surrounding air. The system underwent experimental testing at ambient temperatures ranging from 34.6 ℃ to 30 ℃. Based on the test findings, the system has shown the ability to reduce the air temperature by a maximum of 11.4 ℃. The results also suggest that the cooling effectiveness of the system is affected by variations in air temperature, room temperature, and time.
