A newly designed freezing desalination system was constructed. The system operates on the principle of reversed vapor compression. It is equipped with two identical heat exchangers, one of them works as an evaporator and the other as a condenser. A three-way valve was used to reverse the operation of heat exchangers, causing the ice in the evaporator to melt. The performance of the newly designed system was evaluated in both the forward and the reversed cycles. Electric current, power consumption, pressure drop, water productivity, and specific consumption were all investigated. The experiments were conducted with ice ratios of 0.27, 0.39, 0.45, 0.54, and 0.65 with cycle operating periods of 110, 135, 180, 240, and 300 min. The results showed that the electrical current, power consumption, and pressure drop were decreased with the reversed cycle. The maximum energy-saving percentage was 13% for cycle operation time 300 min. The amounts of freshwater reached 19 L for cycle operation times of 300 min from 30 L saline water. It is recommended to run our newly designed system at an ice ratio of 0.45 since these results save 1.5% in the reversed cycle, which is the most used cycle in the new design.

建造了一个新设计的冷冻海水淡化系统。该系统根据反向蒸汽压缩原理运行。它配备了两个相同的热交换器，其中一个用作蒸发器，另一个用作冷凝器。三通阀用于逆转热交换器的运行，使蒸发器中的冰融化。在正向和反向循环中评估新设计系统的性能。对电流、功耗、压降、水生产率和比消耗量进行了调查。实验以 0.27、0.39、0.45、0.54 和 0.65 的冰比进行，循环操作周期为 110、135、180、240 和 300 分钟。结果表明，电流、功耗和压降随着反向循环而降低。循环运行时间300分钟，最大节能率为13%。对于 300 分钟的循环操作时间，从 30 升盐水中淡水量达到 19 升。建议以 0.45 的冰比运行我们新设计的系统，因为这些结果在反向循环中节省了 1.5%，这是新设计中最常用的循环。
