Diese Studie vergleicht ein Direktexpansionssystem (K„ltemittelsystem) und ein Indirektes Expansionssystem (Wassersystem) zur Beheizung und zur Khlung einer Verkaufsst„tte. Dabei werden zun„chst Grundlagen der K„ltetechnik dargestellt und die vorgegebene Heizlast nach der DIN EN 12833 berprft. Der n„chste Schritt beschreibt die Gasmotorw„rmepumpe. Deren Funktion wird aufgezeigt und Berechnungen fr den Heiz- und Khlmodus werden angestellt. Daraufhin erfolgt die Auswahl der passenden Gasmotorw„rmepumpe, wobei die Nennleistung zwischen den zu konzipierenden Systemen variiert. Aufgrund des einzubringenden Auáenluftanteils, nach der DIN EN 13779, wurde der Einsatz eines RLT-Ger„tes fr die Verkaufsst„tte, unter Bercksichtigung des Brandschutzes und der Ger„uschbel„stigung, geprft. Unter Bercksichtigung verschiedener Kriterien erfolgte eine Auswahl der dezentralen Klimaeinheiten fr die šbertragung der Heiz- und Khlenergie an den jeweiligen Raum. Die Verkaufsst„tte verfgt ber einen hochfrequentierten Eingangsbereich, welcher durch eine geeignete Abschirmvariante ausgestattet werden muss. Durch die Wirtschaftlichkeitsbetrachtung nach der VDI 2067 wurden die Systemvarianten Direktexpansions-, Indirektes Expansions- und Alternativsystem miteinander verglichen. Ein wesentlicher Auswahlaspekt war hierbei die Umweltfreundlichkeit des Systems, bei dem der Ausstoá von CO2 pro Jahr ermittelt wurde. Dies ist selbstverst„ndlich wichtig aufgrund der Erderw„rmung infolge eines erh”hten CO2- Ausstoáes und einem daher erstrebenswerten sinnvollen Umgang mit endlichen fossilen Brennstoffen. Dabei wurde die Gasverbrennung und der elektrische Strom, welcher in Kraftwerken erzeugt wird, in Betracht gezogen. Das System mit der optimalsten Wirtschaftlichkeit und mit den vorteilhaftesten ”kologischen und ”konomischen Aspekten wurde vom Autor ausgew„hlt.
This book supports HVAC planners in reducing the cooling energy demand, improving the indoor environment and designing more cost-effective building concepts. High performance buildings have shown that it is possible to go clearly beyond the energy requirements of existing legislation and obtaining good thermal comfort. However, there is still a strong uncertainty in day-to-day practice due to the lack of legislative regulations for mixed-mode buildings which are neither only naturally ventilated nor fully air-conditioned, but use a mix of different low-energy cooling techniques. Based on the findings from monitoring campaigns (long-term measurements in combination with field studies on thermal comfort), simulation studies, and a comprehensive review on existing standards and guidelines, this book acts as a commonly accessible knowledge pool for passive and low-energy cooling techniques.

Foundations of Engineering Acoustics takes the reader on a journey from a qualitative introduction to the physical nature of sound, explained in terms of common experience, to mathematical models and analytical results which underlie the techniques applied by the engineering industry to improve the acoustic performance of their products. The book is distinguished by extensive descriptions and explanations of audio-frequency acoustic phenomena and their relevance to engineering, supported by a wealth of diagrams, and by a guide for teachers of tried and tested class demonstrations and laboratory-based experiments. Foundations of Engineering Acoustics is a textbook suitable for both senior undergraduate and postgraduate courses in mechanical, aerospace, marine, and possibly electrical and civil engineering schools at universities. It will be a valuable reference for academic teachers and researchers and will also assist Industrial Acoustic Group staff and Consultants. Comprehensive and up-to-date: broad coverage, many illustrations, questions, elaborated answers, references and a bibliography Introductory chapter on the importance of sound in technology and the role of the engineering acoustician Deals with the fundamental concepts, principles, theories and forms of mathematical representation, rather than methodology Frequent reference to practical applications and contemporary technology Emphasizes qualitative, physical introductions to each principal as an entrée to mathematical analysis for the less theoretically oriented readers and courses Provides a 'cook book' of demonstrations and laboratory-based experiments for teachers Useful for discussing acoustical problems with non-expert clients/managers because the descriptive sections are couched in largely non-technical language and any jargon is explained Draws on the vast pedagogic experience of the writer
The Foundations of Acoustics

Publisher: Springer Science & Business Media
Research and scientific progress are based upqn intuition coordinated with a wide theoretical knowledge, experimental skill, and a realistic sense of the limitations of technology. Only a deep insight into physical phenomena will supply the necessary skills to handle the problems that arise in acoustics. The acoustician today needs to be well acquainted with mathematics, dynamics, hydrodynamics, and physics; he also needs a good knowledge of statistics, signal processing, electrical theory, and of many other specialized subjects. Acquiring this background is a laborious task and would require the study of many different books. It is the goal of this volume to present this background in as thorough and readable a manner as possible so that the reader may turn to specialized publications or chapters of other books for further information without having to start at the preliminaries. In trying to accomplish this goal, mathematics serves only as a tool; the better our understanding of a physical phenomenon, the less mathematics is needed and the shorter and more concise are our computa tions. A word about the choice of subjects for this volume will be helpful to the reader. Even scientists of high standing are frequently not acquainted with the fundamentals needed in the field of acoustics. Chapters I to IX are devoted to these fundamentals. After studying Chapter I, which dis cusses the units and their relationships, the reader should have no difficulty converting from one system of units to any other.
