Book Description
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.

Book Description
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.

Book Description
There is a growing concern about fluctuating energy prices, energy security, and the impact of climate change. Buildings are amongst the primary energy consumers in the world. This fact underlines the importance of targeting building energy use as a key to decreasing any nation's energy consumption. According to the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Research Strategic Plan 2010-2015, even limited deployment of Net-Zero-Energy buildings within this timeframe will have a beneficial effect by reducing the pressure for additional energy and power supply and the reduction of GHG emissions. The building sector is poised to significantly reduce energy use by incorporating energy-efficient strategies into the design, construction, and operation of new buildings and retrofits to improve the efficiency of existing buildings.
