摘要
建立了以水为热交换媒介的太阳能热电模块制冷实验系统。系统配置了双位能量存储装置,用以储存昼夜温差能和太阳光电转换电能,以备无日照或日照不足时系统能够连续工作。热电制冷装置模块化,用以适应制冷功率变化较大的空间制冷,并在制冷启动与温度维持不同阶段实现较大功率的切入或撤出。制冷模块以半导体热电元件为核心,冷热端均以导热性能良好的紫铜作为热交换材料,以热容量较大的水作为冷却液和散热循环液。热交换装置采取集合散热冷却分流的集散一体化热交换系统。对制冷模块制冷性能进行了实验分析,并对制冷效果进行了模拟实验,实验结果基本达到了设计的预期。
The solar pyroelectricity module refrigeration experiment system was built taking water as heat exchange intermediary. The system deployed dual energy memory device to store the energy of day and night temperature difference, so it would be able to continue working for the system if sunshine was insufficient. Refrigeration was modularized in order to suit for space refrigeration with great power changing, and to realize high-power in or out at starting refrigeration and maintaining different temperature periods. Semiconductor pyroelectricity components were mainly used in refrigeration module, red copper as heat exchange material for its fine heat conduction function at the cold or hot end, water was used as cooling liquid and heat circulation liquid. Heat-exchanging system adopted integration heat-exchange system. The experimental analysis and simulation were carried out on the property of refrigeration module, the results met the design basically.
