摘要
介绍了以氨-水为工作介质的制冷/制热潜能储存工作循环和流程;根据工作循环的特点提出了循环的计算方法,并对工作循环进行了详细的计算和分析.可以发现,以氨-水为工作介质的制冷/制热潜能储存系统具有较广的工作范围,不仅可用于蓄能空调系统,还可用于0℃以下的蓄能制冷.根据不同的需要,工作溶液的蓄能密度可以在较大的范围内改变,最大的蓄能密度可以超过冰蓄冷,但其代价是降低了系统的COP值.
A detailed introduction dealing with the cycle and the working flow of refrigerating/heating potential storage (R/HPS) technology in which NH_3-H_2O is used as the working fluid is presented. Based on the characteristics of the cycle, the calculation methods of the cycle are described. With these methods, detailed calculation and analysis are carried out for R/HPS system. Results show that the system can run in a larger range of the working temperature. R/HPS system can be applied not only to energy storage air-conditioning system, but also to energy storage refrigeration system in which the evaporation temperatures are lower than 0 ℃. According to different requirements, the storage density of the working fluid can be changed in a larger range. The maximum storage density of the working fluid can exceed that of the ice cold energy storage. However, to increase the storage density of working fluid is at the cost of dropping the coefficient of performance (COP) of RPS system.
