The lack of breakthrough in the design technologies of sea water cooling tower calls for a more systematic investigation into this topic to provide necessary theoretical bases for the extensive application of seawater cycling and cooling technology in China, and at the same time lay foundation for the design of seawater cooling tower. Major research topics include:

(1) Typical salinity distribution in China’s offshore areas.
(2) Affective factors and mechanism of thermodynamic differences between seawater and fresh water cooling towers.
(3) Characteristics of thermal resistance of fillers that are of different sea water salinities.
(4) Methods to evaluate and formula to convert the influences of different sea water qualities upon the thermodynamic characteristics.
(5) Methods to calculate and formula to modify thermal resistance of seawater cooling towers.
(6) Characteristics of column internal materials presently used at home and abroad, and domestic column internal materials suitable for seawater cooling towers.
(7) Concentration multiple of foreign sea water cycling, and bases and principles to decide such multiple.
(8) Filler improving plan applicable to different sea water qualities.
Major renovations include:
(1) It is the first time in China to systematically research on the seawater cooling tower technology in China.
(2) Theoretical discoveries of relation between the thermodynamic characteristics of seawater cooling tower and sea water quality, as well as the formula to calculate such relation, laying theoretical foundation for the thermodynamic calculation of seawater cooling towers.
(3) The modification formula offset the shortcomings of the assumed evapotranspiration flux, making a sound matching between the calculated and experimented results while increasing its applicability.
The achievements of the research have been included into the Guidance for Designing Seawater Cooling Tower compiled by China Power Engineering Consultation Group Corporation, and become the domestic guiding principles for designing large-scale seawater cooling towers. The formula is adopted by the thermodynamic calculation program developed by North China Power Engineering Co., Ltd.
