The study aims to explore the practicality of using ice as a cooling medium to enhance the efficiency of a portable evaporate cooler, particularly by harnessing the latent heat of fusion. The researchers constructed a portable evaporate air cooler and food chiller using a commercially available polyurethane insulation box. This box was combined with a galvanized iron conduit, which served to guide the airflow. This setup effectively isolated the airflow from direct contact with the ice while still allowing for thermal conduction between the ice and the surrounding air. The experimental testing was conducted across a range of ambient temperatures, specifically between 34.6°C and 30°C. This range likely represents typical conditions where such a cooling system might be used. According to the test results, the system demonstrated the capability to lower the temperature of air by up to 20°C. This significant reduction suggests that the system was effective in providing cooling. Additionally, the findings indicated that the cooling efficiency of the system was influenced by fluctuations in air temperature, outdoor temperature, and the duration of operation. Overall, the study provides empirical evidence supporting the viability of using ice as a cooling agent to enhance the efficiency of a portable evaporate cooler and food chiller. However, the study also emphasizes the need to consider factors such as ambient temperature fluctuations and operational duration when evaluating the system's performance. These insights can inform further research and development efforts aimed at improving the design and effectiveness of portable cooling systems.
