Evaporative Coolers for the Postharvest Management of Fruits and Vegetables covers world demand for food of high quality without chemical preservatives and with extended shelf life. The book provides the practical application of evaporative coolers, with a strong focus on postharvest management and fruit/vegetable science as high moisture foods are highly perishable. Special emphasis is laid on the impact of the evaporative coolant structure on the nutritional and food safety content of fresh produce. Moreover, the book covers the effect of evaporative coolant structure towards the reduction of spoilage microorganisms responsible for the spoilage of post-harvest losses of various fruits and vegetables. Edited by a team of specialists, this title also helps people dealing with microbiology understand how this simple technology can help improve product quality for communities that currently lack access to cooling or have unreliable power supplies.

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.

The use of High Density Polyethylene (HDPE) lining in seepage prevention in dams was identified to reduce the cost of water storage. To make it acceptable to end users, it is necessary to determine its lifespan when exposed to tropical climates using viscoelastic models. The Findley Power Law was used to build a model for prediction of the material behaviour at elevated temperature in both short term and long term applications. Time-Temperature Superposition (TTSP) was also used to develop master curves for prediction of long term properties. Micrographs were presented to track the changes during the aging process under different conditions. A simple model was developed for estimation of the service life of the HDPE lining that only requires determination of maximum strain at a given temperature. It was further concluded that the welded joint was the most serious factor undermining the service life of the lining material under tensile creep and that alternating temperature had a more damaging effect on the lining material than elevated temperature hence the lining is likely to suffer more damage in the tropics than in other climates.
