Book excerpt: 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

This book was released on 2023-04-27 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book excerpt: This book systematically discusses state-of-the-art dew-point evaporative cooling and provides key insights into current research efforts and future research interests. Novel energy-efficient and environment-friendly cooling technologies are essential to reduce the sharply rising energy consumption and greenhouse gas emissions and achieve carbon neutrality. Conventional air-conditioners which adopt a vapor compression cycle are neither energy-efficient nor sustainable due to the use of compressors and chemical refrigerants, as well as their intrinsic coupling of sensible and latent cooling loads. With the merits of high energy efficiency and the ability to decouple cooling loads without using chemical refrigerants, indirect dew-point evaporative cooling provides an ideal alternative solution to air conditioning in a variety of applications. A comprehensive review of evaporative cooling and their underlying engineering challenges is included. Advanced engineering and modeling experience critical to the development of dew-point evaporative coolers are highlighted. The effective analysis techniques for dew-point evaporative coolers are documented, and their intrinsic characteristics captured by these methods are reported. Lastly, advanced dew-point evaporative cooling systems in various energy-connected applications are discussed by providing multiple case studies. Specifically targeted at HVAC engineers, thermal scientists, and energy-engineering researchers, this book will balance fundamental concepts, industrial applications, and leading-edge research. As this book provides readers with depth and breadth of coverage, it can also be used by graduate-level students in relevant fields.

Book excerpt: The aim of this book is to supply valid and reasonable parameters in order to guide the choice of the right model of industrial evaporative tower according to operating conditions which vary depending on the particular industrial context: power plants, chemical plants, food processing plants and other industrial facilities are characterized by specific assets and requirements that have to be satisfied. Evaporative cooling is increasingly employed each time a significant water flow at a temperature which does not greatly differ from ambient temperature is needed for removing a remarkable heat load; its aim is to refrigerate a water flow through the partial evaporation of the same.

Book excerpt: Cooling Towers: Principles and Practice, Third Edition, aims to provide the reader with a better understanding of the theory and practice, so that installations are correctly designed and operated. As with all branches of engineering, new technology calls for a level of technical knowledge which becomes progressively higher; this new edition seeks to ensure that the principles and practice of cooling towers are set against a background of up-to-date technology. The book is organized into three sections. Section A on cooling tower practice covers topics such as the design and operation of cooling towers; types of cooling tower; cooling tower components and construction materials; practical aspects of tower selection; industrial applications; and water quality and treatment. Section B is devoted to cooling tower theory and calculations. These include psychrometry; heat transfer theory and calculations; calculations when selecting tower size for a given duty; and the use of charts for calculation of cooling tower duties. Section C on data and tables explains the basis of the SI system of units and includes meteorological tables and data as well as data on specific heat capacity of some common substances.

Available in PDF, EPUB and Kindle. Book excerpt: A new type of air cooler using inexpensive materials, mostly plastics, has been developed in the mechanical Engineering Division of the CSIRO. Extensive Laboratory and field tests have been made. The unit contains a plastic plate heat exchanger, two fans, a water pump and water spray nozzles. Exhaust air from the room being cooled is drawn over wet plates in the heat exchanger and the evaporated water is carried through with the air and discharged outside. Evaporation of the water keeps the plates cool, and fresh air blown past the dry side of the plates is cooled before entering the room without any increase in absolute humidity. It is possible to obtain lower temperatures and humidities in the room than is obtainable from conventional evaporative cooling systems.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
