摘　　要：建立了蓄热式倾斜芯型太阳能蒸馏系统,在实际天气条件下进行了实验研究,分析了给水流量和倾斜角度等对系统性能的影响。结果表明,在倾斜角度为45°时,白天的产水量最高可达4.07 L/m^2,在倾斜角度为30°时,白天的产水量最高可达3.67 L/m^2;随着给水流量的增大,太阳能蒸馏器的产水量降低;注入相变蓄热材料后夜间产水量最大可提高104%,日产水量最高可达到5.16 L/m^2,是传统式太阳能蒸馏器产水量的2.58倍。The inclined solar distillation system is established. The experiments are performed under the condition of the practical weather outdoor. The performance of the system is analyzed with different feed water flow and inclination.The results show that,in the inclination of 45°,the daily water production can be up to 4. 07 L / m^2,and in the inclination of 30°,the daily water production can be up to 3. 67 L / m^2. The production water rate of solar distillation system is reduced with the increase of feed flow rate. The night water production could be increased by 104% after injecting PCM,and the highest water production could reach 5. 16 L / m^2. The production water is 2. 58 times of a traditional solar distillation system.
