Exergy: Energy, Environment and Sustainable Development
This book deals with exergy and its applications to various energy systems and applications as a potential tool for design, analysis and optimization, and its role in minimizing and/or eliminating environmental impacts and providing sustainable development. In this regard, several key topics ranging from the basics of the thermodynamic concepts to advanced exergy analysis techniques in a wide range of applications are covered as outlined in the contents.
- Comprehensive coverage of exergy and its applications
- Connects exergy with three essential areas in terms of energy, environment and sustainable development
- Presents the most up-to-date information in the area with recent developments
- Provides a number of illustrative examples, practical applications, and case studies
- Easy to follow style, starting from the basics to the advanced systems

45. oldal - It contains within it two key concepts: • the concept of 'needs', in particular the essential needs of the world's poor, to which overriding priority should be given; and • the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs.
91. oldal - Further features of the superfluid state are the thermomechanical effects and the phenomenon of "second sound." The former effects, which were found by Allen and Harry Jones (1938) and by Daunt and Mendelssohn (1939), involve the spontaneous flow of superfluid from a region of low temperature to a region of higher temperature and conversely the development of a temperature gradient whenever there is a spontaneous flow of superfluid. These effects were explained by Laslo Tisza ( 1938) and by Heinz...
17. oldal - Q/7~at that location, and the direction of entropy transfer is the same as the direction of heat transfer. To determine the rate of total entropy generation during this heat transfer process, we extend the system to include the regions on both sides of the wall that experience a temperature change. Then one side of the system boundary becomes room temperature while the other side becomes the temperature of the outdoors.
157. oldal - Ta are the charging and discharging outlet temperatures of the heat transfer fluid, respectively. The subscripts 1 , 2 and 3 indicate the temperature of the storage fluid at the beginning of charging, storing or discharging, respectively. Also, t indicates the liquid state and s indicates the solid state for the storage fluid at the phase-change temperature. In addition, for all cases, the inlet temperatures are fixed for the charging-fluid flow at Ta = -10°C and for the discharging-fluid flow at...

91. oldal - The heat pump principle was discovered before the turn of the century as the basis of all refrigeration. The principle of using a heat engine in a reverse mode as a heat pump was proposed by Lord Kelvin in the nineteenth century, but it was only in the twentieth century that practical machines came into common use, mainly for refrigeration. Beginning in the 1970s, air-source heat pumps came into common use. They have the advantage of being...
47. oldal - It can also be expressed in the simple terms of an economic golden rule for the restorative economy: Leave the world better than you found it, take no more than you need, try not to harm life or the environment, make amends if you do.

304. oldal - they are the primary candidates for light-duty vehicles, for buildings, and potentially for much smaller applications such as replacements for rechargeable batteries." The proton exchange membrane is a thin plastic sheet that allows hydrogen ions to pass through it. The membrane is coated on both sides with highly dispersed metal alloy particles (mostly platinum) that are active catalysts. Hydrogen is fed to the anode side of the fuel cell where the catalyst helps the hydrogen atoms to release electrons...
v. oldal - ... the environment. Exergy analysis is a method that uses the conservation of mass and conservation of energy principles together with the SLT for the design and analysis of refrigeration systems and applications. The exergy method can be suitable for furthering the goal of more efficient energy-resource use, for it enables the locations, types, and true magnitudes of wastes and losses to be determined. Therefore, exergy analysis can...
