潜熱蓄熱プレート式熱交換器の研究

抄録

The world's primary energy consumption continuing to increase due to economic growth and population growth. In particular, the growth rate of energy consumption is high in developing countries, so the energy consumption is expected to increase in the future. In such a background, the importance of technology to effectively utilize the waste heat discharged from factories and power plants etc. is beginning to be widely recognized. The efficient use of the waste heat is a very important issue from the viewpoint of the energy security and the reduction of greenhouse gas emissions through reducing fossil fuel consumption. Besides, the Latent Heat Thermal Energy Storage (LHTES) technology is drawing attention as one of the active utilization technology of waste heat. This technology is able to bridge the gap between the temporal and spatial heat demand and supply. In other words, by storing the waste heat generated in advance, the storage heat will be effectively used for supply of hot water and room heating when it is necessary. In this research, we proposed the newly plate type heat exchanger using latent heat thermal storage which fills the conventional plate type heat exchanger with the phase change material (PCM), and performed the simulation of melting and solidification of PCM. Furthermore, we actually built the prototype latent heat storage exchanger and did the performance test. Finally, we added consideration about practical use possibility.
