摘　　要：提出了一种利用槽式聚光集热器直接加热管内溴化锂溶液,使溴化锂溶液在溶液发生器内实现蒸发再生过程的新型太阳能溶液再生器。对该太阳能溶液再生器在无预热及有预热情况下的吸热再生性能进行了实验研究,结果表明在这2种情况下溴化锂溶液都能够稳定吸热并连续产生蒸汽,但有预热时其日均汽化效率可达0.186,是无预热情况下的3.8倍。A novel solar energy solution regenerator is presented which uses parabolic trough collector to heat the LiBr-H2O solution.The solution evaporates in the regenerator and completes the regeneration.The performance of heat absorption and regeneration of the regenerator with or without the pre-heated progress are analyzed.The results indicate that LiBr-H2O solution in the regenerator can produce steam constantly and steadily in both situations.The daily vapor generating efficiency under the situation of pre-heating is 0.186 which is 3.8 times higher compared with the situation without pre-heating.
