| Outline of Final Research Achievements |
Thermal energy storage air-conditioning system is effective for reduction of daytime peak demand in electric power. In this research project, diffuser installed in storage water tank was developed to have the highest performance. The relationship between various design parameters of storage system and thermal storage performance was introduced through theoretical and experimental study and computer simulation of fluid dynamics, and it was found that there can be the limit in improving performance of diffuser design. The thermal energy storage system of low cost in construction can be easily designed to have the highest performance.
