The composite air cooling system includes a dry wet intermodal system for circulating water and a exhaust condensation system. Northern water scarce areas have higher requirements for cooling products. Air cooling and wet cooling each have their own advantages and disadvantages. The products of cooling water and condensed steam should fully consider the climatic conditions such as sunlight, water, and wind in water scarce areas, and make personalized designs based on the operating mechanisms of air cooling and wet cooling. The heat transfer coefficients of the air side film and water film, as well as the specific heat of air and water, should be fully considered to strike a balance and obtain the best solution. VAN SHARE has developed a series of products over the years, including dry and wet intermodal closed cooling systems and exhaust condensing air cooling islands with peak shaving devices, based on practical application cases.
