The energy consumed by air conditioners accounts for more than 50% of the buildings’ whole energy consumption. Solar energy as an inexhaustible and pollution-free natural energy is considered to be the most promising energy in the 21st century. For this reason the solar energy has obtained international widespread attention. The aim of this topic is to take advantages of the solar adsorption refrigeration technology and its distinguished feature, the stronger the solar radiation the greater system capacity, to achieve continuous refrigeration and air conditioning in summer. This design starts from solar absorption refrigerating principles, the cycle of continuous cooling process and the refinement of the whole process of adsorption refrigeration then ends with designs of solar energy collectors with vacuum tubes, heat storage water tank, etc. The design of vacuum tube solar energy collectors aims to meet the demand of hot water for absorption refrigeration machine. Then the heat storage water tank aims to fulfill hot water demand. On the other hand, the heat water tank is equipped with a electrical heating system, it is back-up energy to provide hot water for absorption refrigeration machine. According to the refrigerating output the fan coil system and pipelines are designed. Finally, the 100m2 solar energy collectors with vacuum tubes drive the absorption refrigeration machine which provides 12KW refrigerating output and reaches 0.5 COP. It demonstrates that solar powered absorption refrigeration system which could continuously air conditioning a single construction in Shanghai during summer is possible.
