Research Status and Development on Latent Energy Storage Technology of Building

As an important building energy saving technology, latent energy storage technology can solve the mismatch between energy supply and demand in time,space and strength. The preparation and thermal conductivity enhancement of building energy storage phase change materials, the heat transfer characteristics and enhancement of a phase change unit, the development and application of building phase change energy storage system are reviewed. The deficiency of materials research and development, system performance evaluation and system application technology development is summarized, and this paper points out the focus of further research, namely, developing the phase change materials with stable performance and strong heat storage or release capability, predicting dynamic performance of multi-physical processes and multi-phase energy storage system effectively and achieving an objective that the energy storage system could run independently and effectively without human intervention.
