This book serves as a guide for discovering pathways to more efficient energy use. The first part of the book illustrates
basic laws of energy conversion and principles of thermodynamics. Laws of energy conservation and direction of energy conversion
are formulated in detail, and the types of thermodynamic processes are explained. Also included is the characterization of
various types of real energy conversion. The second part of the book discusses types of energy conversion referred to as thermal-energy
technologies. The advantages of the co-generation processes and devices operating within the Brayton direct cycle and their
adaptively to household energetics are underlined.
