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

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. - Thoroughly explores shelf-life extensions that can be achieved when applying evaporative cooling - Covers postharvest management through evaporative cooling - Brings food and consumer science aspects from evaporative cooled fruits and vegetables - Presents information on the interaction of edible coatings towards the extension of climacteric and non-climacteric fruits

Air conditioning boosts man's efficiency no less than his comfort. Air-conditioned homes, offices, and factories unmistakably raise human productivity and reduce absenteeism, turnover, mistakes, accidents and grievances, especially in summer. Accordingly, many employers every year cool workrooms and offices to raise summer profits. Employees in turn find cool homes enhancing not only comfort and prestige but also personal efficiency and income. With such economic impetus, low-cost summer cooling must irresistibly spread to all kinds of occupied buildings. Refrigeration provides our best cooling, serving well where people are closely spaced in well-constructed, shaded, and insulated structures. However, its first and operating costs bar it from our hottest commercial, industrial, and residential buildings. Fortunately, evaporative cooling is an economical substitute in many regions. First used in Southwest homes and businesses and in textile mills, it soon invaded other fields and climates. In 1946, six firms produced 200,000 evaporative coolers; in 1958, 25 firms produced 1,250,000, despite the phenomenal sale of refrigerating window air conditioners. Though clearly secondary to refrigeration, evaporative cooling is 60 to 80 percent is economical for moderate income groups and cheaper to buy and operate. Thus, it climates where summers are short. Moreover, it cheaply cools hot, thinly constructed mills, factories, workshops, foundries, powerhouses, farm buildings, canneries, etc., where refrigerated cooling is prohibitively expensive.

Engineers often find themselves tasked with the difficult challenge of developing a design that is both technically and economically feasible. A sharply focused, how-to book, Engineering Economics and Economic Design for Process Engineers provides the tools and methods to resolve design and economic issues. It helps you integrate technical a
