The cold storage system utilizes the superior heat transfer characteristics of heat pipe and eliminates drawbacks found in the conventional thermal storage system. The system consists with three main parts, solar cool-storage system, loop heat pipe and evaporative condenser. The solar cool-storage system can operate properly without any external power input and control the indoor conditions automatically by using the intelligent comfortable database technology. The result of the performance test shows that different heat transfer mechanisms including nucleate boiling, geyser boiling and natural convection are identified in different experimental systems with various liquid fills. The investigative RC model shows good prediction in the nucleate boiling stage of cold storage process. Summarizing the test result of the loop heat pipe shows that the permeability of the polymer wicks with different porosity, formulas of polystyrene wick structure and polymethylmethacrylate wick structure between permeability and porosity expressed specific are and . The maximum heat transfer capacity of the LHP is 200W and the thermal resistant is 0.177oC/W. The COP of the evaporative condenser is 25% higher and its pump power consumption is 5% lower than the conventional system. The evaporative condenser operates with its best performance when the condensing pressure is 1280kPa. The optimal operating state of the solar cold-storage air conditioner is achieved automatically by using the intelligent comfortable database technology. The proposed system can achieve its optimal operating condition in one sec and provide comfort environment under dynamic heat load, which is form 400W to 1200W in our experimental conditions.太陽能儲冰式冷氣機儲能系統迴路熱管蒸發冷卻式冷凝器Solar Ice Storage Air-Conditioning SystemEnergy Storage SystemLoop Heat PipeEvaporative Condenser
