本文对新加坡、马来西亚和类似热带地区采用真空管太阳能集热器的太阳能联合吸附制冷循环的性能进行了理论分析。这种新型循环融合了活性碳(AC)-R507A作为底部循环和活性碳-R134a循环作为顶部循环，在底部循环中提供低至−10°C的制冷负荷。利用新加坡和马来西亚的气象资料，开发了太阳能联合吸附制冷循环的模拟和性能评估程序。结果表明，联合循环与天气是同步的。根据循环时间、切换时间、回热和盐水入口温度计算了最佳制冷量、性能系数(COP)和制冷效率。
This paper presents the theoretical analysis of the performance of solar powered combined adsorption refrigeration cycles that has been designed for Singapore and Malaysia and similar tropical regions using evacuated tube solar collectors. This novel cycle amalgamates the activated carbon (AC)-R507A as the bottoming cycle and activated carbon-R134a cycle as the topping cycle and deliver refrigeration load as low as −10 °C at the bottoming cycle. A simulation program has been developed for modeling and performance evaluation for the solar driven combined adsorption refrigeration cycle using the meteorological data of Singapore and Malaysia. The results show that the combined cycle is in phase with the weather. The optimum cooling capacity, coefficient of performance (COP) and chiller efficiency are calculated in terms of cycle time, switching time, regeneration and brine inlet temperatures.
