摘要

利用实验的手段研究了位于真空集热管内的溴化锂溶液，在室外环境中接受连续变化的太阳辐射时，溴化锂溶液的吸热升温及汽化特性.通过对实验数据的分析表明位于真空集热管内的溴化锂溶液吸热效果良好，温度升高较为迅速，能够连续而且稳定地产生蒸汽；特别是在加装反射板的情况下，溴化锂溶液的吸热升温及汽化效果更为显著；计算得出单根真空集热管的理论制冷量可以达到8.9～12.8 W，瞬间集热效率位于17.7%～39.0%之间.

Abstract

Heat absorbing and vaporization characteristics of Lithium bromide solution is tested outdoor in evacuated solar collector tubes. The result shows that Lithium bromide solution in vacuum tubes can be heated up rapidly and vaporized continuously and steadily

especially when using a reflector. Equivalent cooling capacity and instant heat collecting efficiency per vacuum tube are 8.9~12.8W and 17.7%~39.0% respectively.
