摘要
提出一种开放式循环太阳能海水淡化系统 ,热力学效率和得水率是反映该系统能量利用程度及淡水产量和能耗关系的综合性指标。受加热、蒸发和冷凝三个环节制约。对诸多参数进行了分析 ,表明蒸发器入口海水温度和冷却水温度是影响系统性能的最重要两个参数 。
A new kind of solar desalination unit for sea water,of which the performance is dominated by three components,solar collector,crossflow evaporator and condenser,is introduced in this paper.Thermal efficiency reflecting the utilization completeness of thermal energy,and fresh water yielding ratio representing the relation of the production of fresh water and the energy consumption,are two performance indexes for this system.Numerical analysis indicates that the inlet water temperatures of evaporator and condenser are the most important parameters impacting the system performance.It is proved that this system is of potential to be used as desalination unit.
