The Energy Consumption in Refrigerated Warehouses


Book Description

This book explores the philosophical understanding of the “energy consumption” in warehousing process that can be found in the literature. It presents known technical solutions that, if they are used in cold storage rooms, can effectively reduce energy consumption: through lower power consumption and/or energy recovery, such as the use of photovoltaic panels. The final part of the book explores the problems discussed on the basis of a concrete example – a project involving energy recovery in a refrigerated warehouse.This publication also describes the design of refrigerated warehouses, taking into account their energy intensity. In the case of logistic warehousing systems, the pallets in warehouses can offer a source of energy – namely of the potential energy stored in the loads on the shelves. Given that today’s construction warehouses have heights on the order of several tens of meters, that energy can be considerable. In the case of refrigerated warehouses and cold storage facilities, it is necessary to monitor the stored goods in order to maintain a constant freezing temperature, in keeping with the requirements of the HACCP system. Inevitably, this calls for constant cooling of the air inside the warehouse, and thus produces a fixed, high and constant level of energy usage. And, just as in any other context, it becomes important to identify methods for reducing energy consumption.

Advanced Concepts for Renewable Energy Supply of Data Centres


Book Description

The rapid increase of cloud computing, high performance computing (HPC) and the vast growth in Internet and Social Media use have aroused the interest in energy consumption and the carbon footprint of Data Centres. Data Centres primarily contain electronic equipment used for data processing (servers), data storage (storage equipment), and communications (network equipment). Collectively, this equipment processes, stores, and transmits digital information and is known as information technology (IT) equipment. Advanced Concepts for Renewable Energy Supply of Data Centres introduces a number of technical solutions for the supply of power and cooling energy into Data Centres with enhanced utilisation of renewable energy sources in order to achieve low energy Data Centres. Because of the high energy density nature of these unique infrastructures, it is essential to implement energy efficiency measures and reduce consumption before introducing any renewable energy source. A holistic approach is used with the objective of integrating many technical solutions such as management of the IT (Information Technology) load, efficient electrical supply to the IT systems, Low-Ex air-conditioning systems, interaction with district heating and cooling networks, re-use of heat, free cooling (air, seawater, groundwater), optimal use of heat and cold storage, electrical storage and integration in smart grids. This book is therefore a catalogue of advanced technical concepts that could be integrated into Data Centres portfolio in order to increase the overall efficiency and the share of renewable energies in power and cooling supply. Based on dynamic energy models implemented in TRNSYS some concepts are deeply evaluated through yearly simulations. The results of the simulation are illustrated with Sankey charts, where the energy flows per year within the subsystems of each concept for a selected scenario are shown, and graphs showing the results of parametric analysis. A set of environmental metrics (as the non-renewable primary energy) and financial metrics (CAPEX and OPEX) as well of energy efficiency metrics like the well-known PUE, are described and used to evaluate the different technical concepts.







Food Processing


Book Description

Food Processing: Principles and Applications second edition is the fully revised new edition of this best-selling food technology title.Advances in food processing continue to take place as food scientists and food engineers adapt to the challenges imposed by emerging pathogens, environmental concerns, shelf life, quality and safety, as well as the dietary needs and demands of humans. In addition to covering food processing principles that have long been essential to food quality and safety, this edition of Food Processing: Principles and Applications, unlike the former edition, covers microbial/enzyme inactivation kinetics, alternative food processing technologies as well as environmental and sustainability issues currently facing the food processing industry. The book is divided into two sections, the first focusing on principles of food processing and handling, and the second on processing technologies and applications. As a hands-on guide to the essential processing principles and their applications, covering the theoretical and applied aspects of food processing in one accessible volume, this book is a valuable tool for food industry professionals across all manufacturing sectors, and serves as a relevant primary or supplemental text for students of food science.







Research Anthology on Food Waste Reduction and Alternative Diets for Food and Nutrition Security


Book Description

The world population is expected to increase exponentially within the next decade, which means that the food demand will increase and so will waste production. The increasing demand for food as well as changes in consumption habits have led to the greater availability and variety of food with a longer shelf life. However, there is a need for effective food waste management and food preservation as wasted food leads to overutilization of water and fossil fuels and increasing greenhouse gas emissions from the degradation of food. The Research Anthology on Food Waste Reduction and Alternative Diets for Food and Nutrition Security explores methods for reducing waste and cutting food loss in order to help the environment and support local communities as well as solve issues including that of land space. It also provides vital research on the development of plant-based foods, meat-alternative diets, and nutritional outcomes. Highlighting a range of topics such as agricultural production, food supply chains, and sustainable diets, this publication is an ideal reference source for policymakers, sustainable developers, politicians, ecologists, environmentalists, corporate executives, farmers, and academicians seeking current research on food and nutrition security.
