报告题目：Phase Change Material and Thermal Energy Storage Systems
报告人：Tan Jiak Kwang
A phase change material (PCM) is a material that changes phase at a certain temperature. During the phase change process, a PCM absorbs or releases a large amount of heat in order to carry out the transformation. We have successfully developed a phase change thermal energy storage system for a refrigeration system. No degradation in thermal capacity is observed over the testing period. The refrigeration system together with the storage facility successfully achieves a peak demand reduction during the summer period. The system is able to shift the electricity load from the peak to off-peak electricity period using PCM (ability to discharge for a maximum of 8hours).
We have also successfully developed a software, KOOLSIM™ for the design and simulation of thermal system. The software can be used to design and investigate customized heat, ventilation, and air conditioning system and simulation of thermal system. we are also conducting research to design and incorporate high temperature phase change thermal energy storage system for concentrating solar power (CSP) plants.
