Experimental study on flat plate solar heating and cooling combined system

该文提出一种全新的平板式太阳能供热与制冷联合循环新思路 ,并进行了实物样机制作。将传统太阳能集热器的吸热芯片插入太阳能吸附制冷吸附集热器内的吸附剂中间层 ,有效地解决太阳能吸附制冷循环过程中吸附床的散热问题 ,并可有效回收吸附床的显热及吸附热供用户使用。用石英碘钨灯模拟太阳能辐射能量对实物样机进行了试验 ,结果表明 ,在接受外界能量 16～ 18MJ/m2 的情况下 ,集热面积为 0 .9m2 的平板型太阳能冷热联供装置可对外输出 5 kg的冰 ,并可使热水箱内 6 0 kg的水温升高 18℃ ,系统制冷 COP在 0 .11～ 0 .12之间 ,总的供热效率在 0 .4 5左右。通过试验 ,证明了所提出的平板式太阳能冷热联供装置结构简单、性能可靠 ,对太阳能的合理利用作出了一次有效的尝试。

A new flat plate solar combined system with heating and cooling was proposed and experimental prototype device was constructed. A traditional flat plate solar collector absorber was immersed inside adsorbent bed in the new combined system, the radiated heat about adsorbent bed at night can be solved efficiently, also the sensible heat and adsorption heat of adsorbent bed can be reused efficiently. The experimental results with quartz lamps showed that this combined heating and cooling system with 0.9 m 2 collector can produce 5.0 kg ice, also make the temperature of 60 kg water increase 18℃ under the condition of accepting the radiation energy of 16~18 MJ/m 2. The COP of this combined heating and cooling system is about 0.11 ~0.12, and the heating efficiency of this system is about 0.45. The structure of the flat plate combined heating and cooling system is simple and the property of this system is good. The successful experimental achievement has demonstrated an efficient way of the application of solar energy.
