Natural draft towers can be used for cooling and ventilatingstructures. From an operational perspective,the downdraft evaporatively cooled tower is preferred for a dry climate. Solar chimneys, when used alone, tend to require an excessively large solar collector area when appreciable quantities of air must be moved. When used m combination with a downdraft tower, the roof and attic of buildings may assistthe solar chimney and their use becomes more attractive. Both a frame building and a greenhouse were successfully cooled during this program. The economms of the downdraft tower compare favorably with conventional evaporative coolingforsome applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
