This book is a basic textbook of comprehensive thermal science and energy utilization technologies, which is divided into two parts: Engineering Thermodynamics and Heat Transfer. Engineering Thermodynamics mainly introduces the basic concepts and laws of thermodynamics, thermophysical properties of commonly used working medium, analysis of typical thermal processes and cycles and ways to improve the cycle efficiency. Heat Transfer mainly introduces the basic laws of heat conduction, convection and radiation, together with the solving methods and technical measures to control the heat transfer process, and design and check methods for heat exchangers. This book absorbs the experience and advantages of similar textbooks, enriches the discussion of basic concepts and laws, and expands the scope of knowledge of thermal engineering. Whether the readers are students embarking on their academic journey or seasoned engineers seeking to enhance their understanding of thermal phenomena, "Thermal Engineering: Engineering Thermodynamics and Heat Transfer" is an indispensable resource that bridges theory with practice, offering invaluable insights into the complexities of thermal systems and their relevance to modern engineering challenges.

Scientific Essay from the year 2017 in the subject Physics - Thermodynamics, , course: Heat transfer engineering, language: English, abstract: Air-cooled condensers (¿ACC¿) operating in vacuum are widely used at the cold end of contemporary thermal power plants. Proper functioning of the condenser is paramount for power plant efficiency. To adapt to changing process conditions because of changed ambient air temperature or power station load ACC streets are either taken out of or into service or, module fan speed settings are selected appropriately. Even if all fans are running at same speed local variations of cooling air flow may arise as a consequence of e.g. fan location or local wind impact. The designer must ensure that no negative effect (i.e. no cold spot) may evolve at the steam side of the ACC caused by uneven air side cooling or fan control. The following note describes a theoretical method to assess the effect of air flow variations on ACC performance and provides simple rules to avoid potentially risky situations. An important role for safe operation plays the size of the secondary condenser. The procedure may be used as a guideline for proper sizing of the secondary condenser with respect to airflow maldistribution.

Low-Temperature District Heating Implementation Guidebook. This guidebook was written between 2018 and 2021 by seventeen authors within the IEA DHC/CHP TS2 annex. The input came from 250+ literature references and 165 inspiration initiatives to obtain lower temperatures in buildings and heat distribution networks. The author group wrote 40 internal documents about early implementations of low-temperature district heating. Fifteen of these early implementations are presented in this guidebook. The guidebook contains aggregated information about the main economic drivers for low-temperature district heating, how to obtain lower temperatures in heating systems inside existing and new buildings, and how to obtain lower temperatures in existing and new heat distribution networks. An applied study of a campus system in Darmstadt shows the possibility of reducing temperatures in an existing heat distribution network with rather high temperatures. The competitiveness of low-temperature district heating is explored by analysing business models and heat distribution costs. Early adopters of low-temperature district heating are presented by examples and by identified transition strategies. Five groups of network configurations with fourteen variants are presented to be used for low-temperature district heating. Finally, all 165 identified inspiration initiatives and all 137 locations mentioned are listed.
