Abstract: With the application of solar energy storage system with phase change thermal storage to air conditioning and refrigeration, an air conditioning and refrigeration of solar energy storage system with phase change thermal storage was presented. Partial thermo-technical parameters in exothermic process of phase change thermal storage equipment was calculated, and then the heat efficiency of air conditional refrigeration system was analyzed. According to the analysis it was found that this system has avoided instability and discontinuity problems which existed in previous solar energy air conditioning systems. Solar energy storage system with phase change thermal storage is suitable to store solar energy and provide heat source for air conditional refrigeration system due to its good characteristics such as small volume, great heat storage capacity, good uniformity of releasing temperature and easy control.
