| 摘 要： | 为了探索利用太阳能进行储热和供暖的可能性,建立了一套开式循环太阳能储热装置,开展太阳能热利用的实验研究.实验采用天然沸石作为吸附剂,水作为吸附质,沸石床集储热和供热于一体.为了尽可能接近实际应用情况,实验过程全部在冬天寒冷环境下完成.在对冬天太阳辐射能观测的基础上.详细测量了天然沸石床的吸附/脱附的动态特性,对冬天正常日照条件下沸石储热床的吸附/脱附过程的可利用热能进行计算;进而对整个太阳能储热装置的热效率进行分析,为太阳能用于供暖提供基本依据.根据计算,装置的吸附热约为152.5 kJ,脱附热为2 126 kJ,太阳能储热装置的总的热利用效率超过30%.

| Abstract: | In order to explore the application of solar energy in heat storage and heating, a set of solar-powered open cycle system of heat storage was proposed to investigate experimentally the thermal utility of solar energy. Experiments were performed by means of natural zeolite-water as adsorption medium for possible application in winter. Based on continual observation of solar radiation, the dynamic properties of adsorption or des-orption process of the natural zeolite heat storage bed have been determined and the amount of thermal energy available and thermal efficiency were calculated. It was showed that absorption heat and desorption heat were about 152.5 kJ and 2 126 kJ, respectively. Then, thermal efficiency of the solar energy storage set was higher than 30% in present study. |
