This paper proposes a self-filling exhaust-type natural vacuum solar distillation system for seawater desalination, which aligns with China’s “green, low-carbon, and efficient” strategy and its “carbon peak and carbon neutrality” goal. The system’s structure and working principle are described, and an experimental apparatus is built to test its water production at different temperatures. The results show that the water production and performance coefficient increase with the water temperature. At a seawater heating mass flow rate of 0.1 kg/s and a temperature of 60℃, the unit cycle water production is 13.77 kg, and the performance factor is 1.80. The paper also analyzes the economic benefits of the system, which aims to improve the desalination speed and rate of seawater, and enhance the wind power generation efficiency.
