This book is geared toward those interested in the engineering and physics of airconditioning and refrigeration devices (chillers). Analytic thermodynamic models are developed for a wide variety of cooling systems and a broad range of operating conditions. These models are easily implemented in the field or laboratory. Although the authors focus upon mechanical (electrically-driven) chillers - primarily reciprocating and centrifugal machines - there is also substantial material on heat-driven absorption chillers. Heat pumps and heat transformers are also addressed. A few less common chiller types are also treated, such as thermoelectric, thermoacoustic and vortex-tube units. The material is presented in a manner that can appeal to both the engineer and the physicist, and can form a bridge between the two communities in their analysis and presentation of cooling systems. In each chapter, the authors try to capture the basic physics of the problem, and to emerge with quantitatively accurate predictive and diagnostic tools. They aim for simple thermodynamic models where the functional dependences of chiller performance on the major operating variables are transparent. And all the models presented are required to stand the test of comparison against experimental performance data. The reader is shown how chillers can be viewed as input-output devices, viewed from the outside and probed with only externally-measurable parameters such as power input, cooling rate and coolant temperatures. measurable parameters such as power input, cooling rate and coolant temperatures. The type of information needed by chiller manufacturers and developers in designing and assembling new designs is alsoprovided. How will a given modification in a chiller component affect efficiency and cooling rate? What is the combination of operating conditions of the individual components that maximizes chiller efficiency at a required cooling rate? Many of the chapters can serve as an industry-oriented course tailored to cooling engineers. The book can also constitute part of a university course on cooling systems. Sections of the book can be included in introductory and advanced thermodynamics courses. Both engineering-oriented and physics-oriented topics are covered in most of the chapters. More than a dozen tutorial examples are included.
The text describes the main features of currently available heat pumps, focusing on system operation and interactions with external heat sources. In fact, before choosing a heat pump, several aspects must be assessed in detail: the actual climate of the installation site, the building’s energy requirements, the heating system, the type of operation etc. After discussing the general working principles, the book describes the main components of compression machines – for EHPs, GHPs and CO2 heat pumps. It then addresses absorption heat pumps and provides additional details on the behavior of two-fluid mixtures. The book presents a performance comparison for the different types, helping designers choose the right one for their needs, and discusses the main refrigerants. Notes on helpful additional literature, websites and videos, also concerning relevant European regulations, round out the coverage. This book will be of interest to all engineers and technicians whose work involves heat pumps. It will also benefit students in energy engineering degree programs who want to deepen their understanding of heat pumps.

The original idea of IS is to send two solid-gas streams to impinge against each other at high velocity, enhancing transfer between phases. IS is classified into two kinds: Gas-continuous impinging streams (GIS) and Liquid-continuous ones (LIS). Impinging Streams describes fundamentals, major properties and application of IS, as a category of novel technologies in chemical engineering. Because of the universality of transfer phenomena, it is receiving widespread attention. This book represents the first book in this area for over 10 years and covers achievements and technologies.* describing clearly the properties of Gas-continuous and Liquid-continuous impinging streams* introducing new technical devices * includes a number of worked application cases, which are illustrated in detail
