Abstract:

A solar-powered adsorption cooling system was designed.The system can realize both open-type circulation mode and closed circulation mode by switching the pipeline.The operation performance under two different circulation modes was studied，which includes temperature variations of solar collector arrays and adsorption chillers as well as refrigerating output variations of the system.From the experiments，it was shown that open-type system operated stably because of regulating effect by heat storage water tank.However，obvious wave characters could be observed in the operation of closed system.Besides，closed system has the advantages of higher solar collecting efficiency as well as higher COP，which leads to evident energy conservation.

摘要：

设计了太阳能吸附式制冷系统，通过管路切换，该系统可实现开式循环方式以及闭式循环方式。研究了两种不同的循环方式下，太阳能吸附式空调系统的运行特性，包括太阳能集热器阵列、吸附式制冷机组的温度变化规律以及系统制冷量的变化规律。实验表明，由于蓄热水箱的调节作用，开式循环的运行工况稳定，而闭式循环在运行过程中具有明显的波动性但其具有较高的太阳能集热效率以及系统COP，节能优势明显。
