Engineering Principles, Modelling and Economics of Evaporative Coolers

Engineering Principles, Modelling and Economics of Evaporative Coolers covers the basic engineering and technical principles behind the operation and construction of evaporative coolers, also highlighting challenges. The book presents the reader with selected case studies on modelling in the cooling chamber and explains the economic implications an evaporative structure can bring. Edited by a team of specialists, the book also explains the strong dependence of the technology's performance on environmental conditions, and hence the limits on temperature control in the preservation of post-harvest agriculture products. Evaporative coolers are an ancient technology, invented long before the introduction of chemical refrigerants as used in modern fridges or cooling towers. This two volume set covers the topic, with practical applications, construction techniques, and operation of the technology. Thoroughly explores unit operations and engineering principles of evaporative coolers Includes CFD modelling on evaporative cooling structures Covers the economics of evaporative coolers INDICE: THEME 1: Background knowledge 1.
