HDH seawater desalination technology has characteristics of flexible scale, small investment, and suitable for decentralized fresh water demand. This paper designs a HDH seawater desalination system, and based on the principles of energy conservation and mass conservation, a theoretical calculation model is established, and the influence of spray liquid flow and temperature, airflow, cooling water temperature and flow on the system water production and Gained output ration (GOR) is studied. And the orthogonal analysis method is used to study the influence of different parameters on water production and GOR. The results show that: water production and GOR are positively related to temperature of the spray liquid, when spray liquid or air flow is large, fresh water output is negatively correlated with air flow, system water production and cooling water flow are positively correlated at first, then system fresh water production tends to be stable, GOR and cooling water flow are first negatively correlated, and then GOR become stable, water production is negatively correlated with cooling water temperature, GOR is positively correlated with cooling water temperature. The spray liquid flow rate has the greatest influence on water production, and spray liquid temperature has the greatest influence on GOR.
