【摘要】 提出了太阳能烟囱海水淡化及热风发电综合系统。以天津地区的气候条件为准,估算出此系统每平方米集热棚面积可年产1.0kWh的电量和0.74t的淡水。对建立的小型冷凝实验验证系统中的冷空气风速、冷凝水产量及温度场进行了测量,给出了高浓度不凝气体—水蒸气间壁冷凝换热的水蒸气冷凝速率模型和理论风速计算公式,用来关联不凝气体浓度、温度等对冷凝换热的影响,为将来综合系统的优化提供理论依据。并根据实验数据对冷凝系统进行了初步设计。更多还原

【Abstract】 The integrated solar chimney system for power and freshwater from seawater has been put forward.1.0kWh wind electric power and 0.74t freshwater per collector square meters per year could be obtained by the integrated system.The vapor condensation velocity model of indirect condensation of air-vapor was discussed to associate the air concentration and temperature with condensation process.In the small experimental system the wind velocity,output of freshwater and temperature were measured for the design of condensation system.更多还原
