| 摘 要： | 为了促进工业中低温余热的利用,设计一种新型的余热回收利用装置——溴化锂储热储冷系统.该系统结构简单,余热利用率高,可以对60 ℃左右的低温工业余热进行收集并加以储存,储存的潜能可以转化成热能,或者在转化成热能的同时产生冷能,这是传统的蓄能技术所不具备的.通过计算分析输出温度、热源温度、溶液质量分数及冷却水温度对系统热效率的影响.结果表明,随着输出温度和冷却水温度的升高,系统热效率下降,而提高热源温度和发生器溶液最终质量分数可以提高系统的热效率.

| Abstract: | A new equipment for industrial waste heat storage—the lithium bromide heat and cold storage system was designed in order to improve the utilization of middle low temperature waste heat. The structure of the system is simple, and the system has high utilization rate of waste heat that can recycle low temperature industrial waste heat of about 60 ℃. Storaged potential energy can converse to heat and cold meanwhile, which the traditional thermal storage technology cannot reach. Thermodynamic calculation in different operating conditions was conducted to find the characteristics of thermal efficiency. How the output temperature, the heat source temperature, the final solution mass fraction and the cooling water temperature affect the thermal efficiency was analyzed. Results demonstrate that the thermal efficiency decreases with the output temperature and the cooling water temperature increasing, while the system thermal efficiency increases with heat source temperature and the final solution mass fraction increasing. |
