| 摘 要： | 在传统两级溴化锂吸收式制冷循环的基础上，从增大热源可利用温差考虑，提出了一种由太阳能驱动的新型吸收式制冷循环，分析计算了低压发生器压力(中间压力)和中间溶液浓度变化对系统热力系数COP和热源可利用温差的影响。结果表明，在发生热源温度85℃~95℃的范围内，中间压力在1.6KPa (12mmHg)和2.2KPa (16.5mmHg)之间取值新型循环有较高的热力系数和较大的热源可利用温差。

| Abstract: | On the basis of the traditional two-level lithium bromide absorption refrigeration cycle, considering that the heat can be increased by the temperature difference, this paper proposes a new absorption refrigeration cycle driven by solar energy to an-alyze and calculate the influence of the system thermal coefficient COP as well as available temperature difference made by the heat source under the low-voltage generator pressure (intermediate pressure) and intermediate solution concentration change. The results show that, within the scope of the occurrence of the heat source temperature of 85℃-95℃, the intermediate pressure be-tween 1.6KPa (12mmHg) and 2.2KPa (16.5mmHg) can obtain the new value which has a higher thermodynamic cycle coeffi-cient and the temperature difference of a larger heat source. |
