研究了太阳能驱动的吸附式制冷系统在不同气候条件下的性能。利用澳大利亚珀斯（南半球代表城市）和约旦安曼（北方半球代表城市）的实时天气数据，研究了集热器面积、集热器坡度、热水温度和流量对系统性能的影响。模拟结果表明，这两个城市有类似的太阳辐射在夏季期间，太阳能吸附式制冷机可以可靠地提供冷却在一个合理的高系统COP。对于CPC（复合抛物面集热器）太阳能集热器总面积为36.22 m（2）的住宅制冷，珀斯天气条件下的平均系统COP为0.491，安曼天气条件下的平均系统COP为0.467，而珀斯和安曼在高峰时间的制冷能力分别为10.3 kW和8.46 kW。当系统以CPC收集器斜率约为30、太阳能储水箱体积为1.4m3、入口热水温度为80 ℃以及热水流速为0.33kg/s运行时，出现最佳性能。进一步的经济分析表明，太阳能驱动的吸附式制冷系统可以减少电力消耗的珀斯和安曼城市分别为34%和28%，相比传统的蒸汽压缩制冷系统。(C)2016爱思唯尔有限公司版权所有
Performance of an adsorption cooling system driven by solar thermal energy was studied under different climatic conditions. The effects of solar collector area, collector slope, hot water temperature and flow rate on the system performance were investigated using the real-time weather data of two cities: Perth, Australia (a representative city in the southern hemisphere) and Amman, Jordan (a representative city in the northern hemisphere). The simulation results showed that the two cities had similar solar radiation during the summer period and that the solar adsorption chiller could reliably provide cooling at a reasonably high system COP. For residential cooling with a total CPC (Compound Parabolic Collector) solar collector area of 36.22 m(2), the average system COP was 0.491 for Perth weather conditions and 0.467 for Amman weather conditions, respectively while the cooling capacity was 10.3 kW for Perth and 8.46 kW for Amman, respectively at peak times. Optimum performance occurred when the system run with the CPC collector slope of around 30, the solar water storage tank volume of 1.4 m(3), inlet hot water temperature of 80 degrees C, and a hot water flow rate of 0.33 kg/s. An economic analysis was further investigated and the results showed that the solar driven adsorption cooling system could reduce the electricity consumption for Perth and Amman cities by 34% and 28%, respectively in comparison to a conventional vapour compression cooling system.
