| 摘 要： | 提出了一个适合于利用太阳能的新型1.x级溴化锂吸收式制冷循环。计算了该循环的性能。结果表明,在现有太阳能集热器所能提供的热水温度范围,1.x级循环克服了单效循环运行范围窄的缺点,其性能指标明显高于两级循环;冷却水先进入冷凝器的串联流程优于并联流程;热水、冷媒水、冷却水温度对溴冷机循环系统的性能系数、热源单耗、面积单耗等经济性指标有较大影响。

| Abstract: | A novel 1.x-lift LiBr absorption refrigeration cycle driving by solar energy is presented. The performance of the new cycle are calculated and analyzed. The results show that within the capable temperature range of conventional solar energy collectors, l.x-lift cycle eliminates the drawback of narrow operation range of single effective cycle, and the coefficient of performance is higher than that of double-lift cycle at same circumstance. The series loop of cooling water with condenser first is superior to parallel loop of cooling water. The inlet temperatures of hot water, chilling water and cooling water have considerable effects on the economical indexes of this system, such as coefficient of performance, unit hot water consumption and unit heat transfer surface of the cycle system. |
