The unique HVAC requirements of supermarkets present a compelling blend of engineering challenges and opportunities. Supermarkets are dynamic environments, with various zones that demand precise temperature, humidity, and ventilation control to ensure the comfort of shoppers, preserve perishable products, and meet stringent regulatory standards. Yet, behind the scenes, these systems must be energy-efficient, sustainable, and seamlessly integrated with refrigeration and automation technologies to control costs and minimize environmental impact. This book, HVAC for Supermarkets: Design, Efficiency, and Operations, is designed for HVAC professionals, supermarket facility managers, and engineers who seek to deepen their understanding of supermarket-specific HVAC design and management. It is also invaluable for anyone involved in building sustainable and efficient retail spaces. In recent years, the growing emphasis on energy efficiency, sustainable practices, and indoor air quality has spurred innovations in HVAC technology. Supermarkets, as complex and energy-intensive facilities, are at the forefront of this evolution. From the basic principles of HVAC design tailored to supermarkets, through integration with refrigeration systems, to the implementation of advanced controls and smart technologies, this book provides practical insights and guidelines for addressing both current challenges and future demands. Through a careful balance of theory, practical advice, and real-world case studies, readers will gain a clear roadmap to designing HVAC systems that not only meet the technical demands of supermarket environments but also contribute to broader sustainability goals. Whether you are an experienced HVAC professional or new to this field, I hope this book becomes an essential resource in your pursuit of efficient, sustainable, and high-performing supermarket HVAC solutions.
Carbon emissions from the retail segment of the food cold chain are relatively high compared to other parts of the food cold chain. Studies have also shown that food temperature is less well controlled at the retail and consumer end of the cold chain. There is therefore considerable potential to optimize performance of refrigerated display cabinets and the refrigeration systems that are used to operate them to reduce carbon emissions and to improve food temperature control. Sustainable Retail Refrigeration draws together world experts on retail refrigeration. In a single resource, the authors cover the latest technologies and best current knowledge in the field. With increasing concerns about energy use and global warming gasses, retailers are increasingly being called to account for their actions. Sustainable Retail Refrigeration is a valuable reference to manufacturers, managers and policy makers, incorporating both a design and an operational perspective.
Advanced District Heating and Cooling (DHC) Systems presents the latest information on the topic, providing valuable information on the distribution of centrally generated heat or cold energy to buildings, usually in the form of space heating, cooling, and hot water. As DHC systems are more efficient and less polluting than individual domestic or commercial heating and cooling systems, the book provides an introduction to DHC, including its potential contribution to reducing carbon dioxide emissions, then reviews thermal energy generation for DHC, including fossil fuel-based technologies, those based on renewables, and surplus heat valorization. Final sections address methods to improve the efficiency of DHC. - Gives a comprehensive overview of DHC systems and the technologies and energy resources utilized within these systems - Analyzes the various methods used for harnessing energy to apply to DHC systems - Ideal resource for those interested in district cooling, teleheating, heat networks, distributed heating, thermal energy, cogeneration, combined heat and power, and CHP - Reviews the application of DHC systems in the field, including both the business model side and the planning needed to implement these systems
This book covers the fundamentals and applications of carbon dioxide vapor compression refrigeration thermodynamic cycles. In particular, it presents new application areas, such as making ice and snow in the Winter Olympic Games, food cooling and refrigeration. The book explores the physical and chemical characteristics of CO2 fluid, and the unique traits of its thermodynamic cycle. The contributors explain how CO2 refrigeration is a developing, eco-friendly technology, and emphasize its importance for refrigeration and air-conditioning in the current and future market. This book is a valuable source of information for researchers, engineers and policy makers looking to expand their applicable knowledge of high-potential refrigeration technology using carbon dioxide. It is also of interest to postgraduate students and practitioners looking for an academic insight into the industry’s latest eco-friendly technologies.

Effective water and energy use in food processing is essential, not least for legislative compliance and cost reduction. This major volume reviews techniques for improvements in the efficiency of water and energy use as well as wastewater treatment in the food industry.Opening chapters provide an overview of key drivers for better management. Part two is concerned with assessing water and energy consumption and designing strategies for their reduction. These include auditing energy and water use, and modelling and optimisation tools for water minimisation. Part three reviews good housekeeping procedures, measurement and process control, and monitoring and intelligent support systems. Part four discusses methods to minimise energy consumption. Chapters focus on improvements in specific processes such as refrigeration, drying and heat recovery. Part five discusses water reuse and wastewater treatment in the food industry. Chapters cover water recycling, disinfection techniques, aerobic and anaerobic systems for treatment of wastewater. The final section concentrates on particular industry sectors including fresh meat and poultry, cereals, sugar, soft drinks, brewing and winemaking.With its distinguished editors and international team of contributors, Handbook of water and energy management in food processing is a standard reference for the food industry. - Provides an overview of key drivers for better management - Reviews techniques for improvements in efficiency of water and energy use and waste water treatment - Examines house keeping proceedures and measurement and process control
This book covers challenges and opportunities related to solar-energy based systems. It covers a wide variety of topics related to solar energy, including applications-based systems such as solar thermal systems that are focused on drying, desalination, space cooling, refrigeration, and processing; recent advances in solar cells (DSSC) and photovoltaics; technologies for storage of energy (both sensible heating as well as latent heating); and the design of concentrated solar receivers.

The contents of this book will be of interest to researchers, professionals, and policymakers alike.
Thermal energy storage (TES) technologies store thermal energy (both heat and cold) for later use as required, rather than at the time of production. They are therefore important counterparts to various intermittent renewable energy generation methods and also provide a way of valorising waste process heat and reducing the energy demand of buildings. This book provides an authoritative overview of this key area. Part one reviews sensible heat storage technologies. Part two covers latent and thermochemical heat storage respectively. The final section addresses applications in heating and energy systems. - Reviews sensible heat storage technologies, including the use of water, molten salts, concrete and boreholes - Describes latent heat storage systems and thermochemical heat storage - Includes information on the monitoring and control of thermal energy storage systems, and considers their applications in residential buildings, power plants and industry
