This book addresses the increasing energy demand and costs associated with the global refrigeration industry, primarily driven by the need for cooling. It proposes the substitution of vapour compression refrigeration systems (VCRS) with vapour absorption refrigeration systems (VARS), which operate on low-grade, renewable energy sources like solar, geothermal, and waste heat. Focusing on the absorber component of VARS, which plays a critical role in facilitating heat and mass transfer processes, the book provides a comprehensive overview of absorber configurations, including tray, packed bed, falling film, spray, bubble, and membrane absorbers. It offers guidance on selecting the appropriate absorber configuration considering their advantages and limitations in different operating conditions, as well as their numerical, experimental, and performance enhancement studies. The book will interest heating, ventilation, and air conditioning (HVAC) academic researchers, graduate students, and professionals involved in the advancement of sustainable refrigeration technologies, particularly absorber selection.

It has long been recognized that realizing the potential for energy conservation and diversification by using heat pumps offers considerable benefits to the environment. Important work on more efficient and ozone-friendly working fluids will further enhance the case for greater support of heat pump research. This book contains the Proceedings of the Third International Energy Agency Conference held in Tokyo in March 1990. The main theme of the Conference, 'Heat Pumps - Solving Energy and Environmental Challenges', is explained in great depth, covering not only technical characteristics but economic factors and the role of government and other bodies in promoting research, and the uses of all types of heat pumps are also fully considered. As well as publishing the papers presented at the meeting, the book also contains the extensive complementary poster sessions from the Conference.

This book highlights key recent developments in air conditioning technologies for cooling and dehumidification with the specific objectives to improve energy efficiency and to minimize environmental impact. Today, air conditioning, comprising cooling and dehumidification, is a necessity in commercial and residential buildings and even in many industrial processes. This book provides key update on recent developments in air conditioning systems, cooling cycles and innovative cooling/dehumidification technologies. Key technologies related to cooling include heat-driven absorption and adsorption cooling and water-based dew point evaporative cooling. Technologies connected with dehumidification involve new generations of adsorbent–desiccant dehumidifiers, liquid-based desiccants and membranes that sieve out water vapor from air. Losses in cooling cycles and thermo-economic analysis for a sustainable economy are also judiciously documented.
