Freeze desalination is a promising technique for wastewater treatment and zero/minimum liquid discharge systems, often requiring multiple stages to produce potable water. This research focuses on developing a Multiple Effect Freeze Desalination (MEFD) system based on experimental data for Single-Stage Desalination Efficiency (SSDE) and Single-Stage Recovery Rate (SSRR). The study analyzes various MEFD setups, calculating cooling energy consumption and correlating it with electrical usage through the coefficient of performance (COP). Comparisons with Reverse Osmosis (RO), Multi Effect Evaporation (MEE), and Multi-Stage Flashing (MSF) suggest that MEFDs may face challenges in matching RO efficiency but can compete with MEE and MSF within specific operational ranges. Exergy assessments indicate difficulties against even 10-stage MSF systems. Achieving SSDE and SSRR levels above 65% enables MEFDs to rival 10-stage MSF plants in terms of energy efficiency, surpassing MEE and MSF at over 85% efficiency. Despite these challenges, MEFDs offer benefits for treating high salt concentrations and resisting corrosion.

冷冻淡化是一种用于废水处理和零/最小液体排放系统的有前途的技术，通常需要多个阶段来生产饮用水。本研究重点基于单级海水淡化效率（SSDE）和单级回收率（SSRR）的实验数据开发多效冷冻海水淡化（MEFD）系统。该研究分析了各种 MEFD 设置，计算冷却能耗并通过性能系数 (COP) 将其与用电量关联起来。与反渗透 (RO)、多效蒸发 (MEE) 和多级闪蒸 (MSF) 的比较表明，MEFD 在匹配 RO 效率方面可能面临挑战，但可以在特定操作范围内与 MEE 和 MSF 竞争。火用评估表明，即使是 10 级 MSF 系统也存在困难。 SSDE 和 SSRR 水平达到 65% 以上，使 MEFD 在能源效率方面可与 10 级 MSF 工厂相媲美，并以超过 85% 的效率超越 MEE 和 MSF。尽管存在这些挑战，MEFD 在处理高盐浓度和耐腐蚀方面仍具有优势。
