海水淡化系统是必要的，以满足日益增长的淡水需求。将海水淡化系统与太阳能技术结合起来是消除对化石燃料能源的需要的一个可能途径。在这里，我们建立了一个技术经济模型，评估耦合太阳能集热器与热海水淡化系统的可行性。该模型考虑了系统寿命和规模、各子系统的单价和性能参数、当地市场和厂址环境因素对特定贴现水生产成本和投资回收期的影响。这种方法消除了技术和地理限制。技术经济模型试图预测太阳能多级闪蒸系统的经济性。如果太阳能集热器单位成本为100美元/m2，效率为40%，则生产1000 m3/天的工厂的特定贴现水生产成本为0.97美元/m3。根据美国七个沿海城市的市场和环境因素，太阳能海水淡化厂最经济可行的地理位置是佛罗里达的迈阿密。
Desalination systems are necessary in order to meet growing demands for freshwater. Coupling desalination systems with solar energy technologies is one possible route for eliminating the need for fossil fuel energy sources. Herein, we build a technoeconomic model that assesses the viability of coupling solar collectors with thermal desalination systems. The model considers the impacts of system lifetime and scale, unit price and performance parameters for each subsystems, local market and environmental factors of plant site on specific discounted water production costs and payback period. This approach eliminates technical and geographic constraints. The technoeconomic model attempts to predict the economics of a solar multi-stage flash distillation system. The specific discounted water production cost for a plant producing 1000m3/dayis$0.97/m3if the solar collector unit cost is$100/m2and operates at 40% efficiency. According to market and environmental factors in seven coastal cities in the United States, the most economically feasible geographic location for a solar desalination plant is Miami, Florida.
