Outline of Final Research Achievements |
I constructed an actual simplified thermal storage tank and measured the thermal performance of the tank.The simple thermal storage tank uses a small water tank with a volume of a cubic meter. A numerical analysis model that considers heat conduction and water flow inside the tank was developed and compared with the measurement results from the experiment.By comparing the results of the numerical analysis model with the actual measurement results, the accuracy of the model could be confirmed then the accuracy was improved. A simulation model of the air conditioning system including the developed numerical analysis model was constructed and it was confirmed that the proposal system could achieve the energy saving by 30% around and 70% of system efficiency improvement.
