摘要
提出一种太阳能驱动的小型风冷氨水吸收式制冷循环系统,该系统有效回收精馏热及吸收热,降低发生温度,实现机组风冷化以及对太阳能的有效利用,增加系统能效比。在建立组成系统各部件热力学数学模型基础上,对循环特性进行计算,得出在热源温度、蒸发温度、冷凝温度等参数变化时,性能因数的变化规律,为系统优化设计提供理论基础。
This paper proposed a solar-driven air-cooled NH3H2O absorption refrigeration cycle,which can increase energy efficient ratio by recovering heat from rectifier and absorber,reduce generating temperature,and realize air-cooled and the effective use of solar energy.Based on the establishment of thermal dynamic mathematical model of each component,the cycle performance was calculated by programe.The influences of the heat source temperature,evaporating temperature,condensing temperature on the coefficient of performance of the refrigerator were analyzed,which lays the foundation for optimization design of refrigeration system.
