| 摘 要： | 对液体干燥剂制冷和除湿能力贮存环节进行了分析，给出一种太阳能干燥剂再生转换装置传热传质数学模型．该储能方式没有因储能介质与周围环境存在温差产生的冷热损失，对ＣａＣｌ２和ＬｉＣｌ等典型液体干燥剂的分析表明，理想情况下，二者的储能密度可达１０００ ＭＪ／Ｍ３和 １４００ ＭＪ／ｍ３，远大于水和冰的蓄能密度，储能密度还受太阳辐射、面盖间距、环境条件等因素影响．

| Abstract: | A mathematical model describing the heat and mass transfers of a solar liquid desiccant regeneration unit is presented in this paper. Analysis regarding the energy storage represented by dehumidification potential of liquid desiccant has been conducted. The usual heat and cold loss for conventional energy storage methods does not occur with respect to the storage of dehumidification potential. Under ideal conditions, the energy storage capacity for CaCl2 and LiCl can reach 1000 MJ/m3 and 1400 MJ/m3 respectively much more than that of ice or water storage. The conditions affecting the storage capacity, such as solar irradiation, ambient conditions, etc., are also identified. |
