In 2011, Changzhou Sunhome Solar Water Heater Manufacture Co., Ltd. established a solar thermal electrical power storage research & development center in Changzhou science city. The R&D team comprises of 20 members including one Professor, one Doctor, six graduates and twelve undergraduates. The test facilities covering 4000 sq.m consists of high temperature storage tank, large scale molten salt heat exchanger, transmission & control of molten salt. The molten salt storage was studied at a laboratory scale before raising the research facility with a 100ton high temperature molten salt storage tank.
Phase Change Materials (PCM) oscillate between solid and liquid phase within a certain temperature range (Mansfield). When the environment’s temperature is higher than that of the PCM, heat transfers from the surroundings to the material, which creates a cooling effect and changes PCM’s state from solid to liquid. When the environment’s temperature is lower than that of the PCM, heat transfers from the PCM to the surroundings, generating a warming effect and PCM changes back to its solid state.
