This textbook explains the meaning of heat and work and the definition of energy and energy systems. It describes the constructive role of entropy growth and makes the case that energy matters, but entropy growth matters more. Readers will learn that heat can be transferred, produced, and extracted, and that the understanding of generalized heat extraction will revolutionize the design of future buildings as thermal systems for managing low grade heat and greatly contribute to enhanced efficiency of tomorrow's energy systems and energy ecosystems. Professor Wang presents a coherent theory-structure of thermodynamics and clarifies the meaning of heat and the definition of energy in a manner that is both scientifically rigorous and engaging, and explains contemporary understanding of engineering thermodynamics in continuum of its historical evolution. The textbook reinforces students' grasp of concepts with end-of-chapter problems and provides a historical background of pioneering work by Black, Laplace, Carnot, Joule, Thomson, Clausius, Maxwell, Planck, Gibbs, Poincare and Prigogine. Developed primarily as a core text for graduate students in engineering programs, and as reference for professional engineers, this book maximizes readers' understanding and shines a light on new horizons for our energy future.

• Brings forth students' understanding of how heat and work are different and why the principle of their inter-convertibility (i.e., exchangeability) should be rejected;
• Elucidates the constructive role of entropy growth, and the notion that energy matters, but entropy growth matters more;
• Demonstrates that heat can be transferred, produced, and extracted;
• Teaches readers that all reversible-like processes are heat extraction processes and how this understanding will revolutionize the design of future buildings.

Autorentext

Professor Lin-Shu Wang is Associate Professor of Mechanical Engineering at the State University of New York at Stony Brook. A lifelong student of thermodynamics and philosophy of science, Dr. Wang has taught courses in engineering thermodynamics for decades and is the inventor of the "Turbo-Cool turbocharging system", "hybrid solar panels", and "reverse-cycle ductless heat pumps for zoned heating and cooling," technologies that, respectively, improve engine energy efficiency and vehicle fuel economy, increase the supply of power and heat from solar energy conversion, and reduce the energy demand for building heating and cooling. He earned his PhD at the University of California, Berkeley.
