Abstract

This study performed of a water cooling system by using a steam ejector and jet condenser to drop the temperature of the water in aquafarm by about 5°C from 25°C or higher. In this research, to replace the present water cooling system, we focused on a water cooling system operated by latent heat of evaporation, thus this system needs a vacuum pressure to evaporate the water in enclosed tank. The water cooling effects are dependent on the vacuum pressure in the enclosed tank, and the cooling water is generated by evaporation. As the experimental results, the absolute vacuum pressure obtained was about 5~8mmHg using a steam driven ejector with jet condenser in experiments from Type 1 to Type12. The temperature difference of the water is about 5°C from Figure 8, 10, 12. Figure 13, 15 and 17 is the graphs of temperature difference of heat exchanger. The obtained results are respectively ΔT=7°C, ΔT=5°C and ΔT=5.5°C. Figure 19, 21 and 23 is the graphs of temperature difference of heat exchanger. The obtained results are respectively ΔT=5.5°C, ΔT=5.5°C and ΔT=5.5°C.
