This book discusses nocturnal cooling technologies for building applications. Exploiting the natural environment as a renewable and sustainable resource has become a significant strategy for passive energy saving in buildings, and has led to growing interest in the use of passive radiative cooling based on nighttime (nocturnal) and daytime (diurnal) operating periods. Of these, nocturnal cooling is more promising since diurnal cooling is hard to achieve due to the solar radiation effect. As such, this book provides a comprehensive overview of nocturnal cooling for building applications, including a definition, concepts and principles; materials and devices; and cooling systems and configurations.

This book explores how lighting systems based on LED sources have the ability to positively influence the human circadian system, with benefits for health and well-being. The opening chapters examine the functioning of the human circadian system, its response to artificial lighting, potential health impacts of different types of light exposure, and current researches in circadian photometry. A first case study analyzes the natural lighting available in an urban interior, concluding that it is unable to activate the human circadian system over the entire year. Important original research is then described in which systems suitable for artificial circadian lighting in residential interiors and offices were developed after testing of new design paradigms based on LED sources. Readers will also find a detailed analysis of the LED products available or under development globally that may contribute to optimal artificial circadian lighting, as well as the environmental sensors, control interfaces, and monitoring systems suitable for integration with new LED lighting systems. Finally, guidelines for circadian lighting design are proposed, with identification of key requirements.

Die Autoren untersuchen die Voraussetzungen fur eine erfolgreiche Vergabestrategie bei Grossprojekten. Zunachst analysieren sie die Risiken fur die am Bau Beteiligten und stellen Varianten dar, wie Planungs- und Bauleistungen zu vergeben sind. Danach werden die Moeglichkeiten und Grenzen von in jungerer Zeit "in Mode gekommenen" Vergabemodellen, insbesondere die Vergabe mit Garantiertem Maximalpreis bzw. die Beauftragung von Construction Managern, diskutiert. Hierauf und auf einer Analyse der typischen Struktur eines (grossen) Bauprojekts aufbauend, wird ein Vergabemodell entwickelt, das einerseits den Risiken der Baubeteiligten Rechnung tragt, andererseits dem Bauherrn die erforderliche Flexibilitat belasst. So kann er in einem kompetitiven Umfeld ein seinen Vorstellungen bezuglich Kosten, Qualitaten und Terminen entsprechendes Bauvorhaben realisieren.

This book elaborates on different aspects of the decision making process concerning the management of climate risk in museums and historic houses. The goal of this publication is to assist collection managers and caretakers by providing information that will allow responsible decisions about the museum indoor climate to be made. The focus is not only on the outcome, but also on the equally important process that leads to that outcome. The different steps contribute significantly to the understanding of the needs of movable and immovable heritage. The decision making process to determine the requirements for the museum indoor climate includes nine steps: Step 1. The process to make a balanced decision starts by clarifying the decision context and evaluating what is important to the decision maker by developing clear objectives. In Step 2 the value of all heritage assets that are affected by the decision are evaluated and the significance of the building and the movable collection is made explicit. Step 3. The climate risks to the moveable collection are assessed. Step 4: Those parts of the building that are considered valuable and susceptible to certain climate conditions are identified. Step 5. The human comfort needs for visitors and staff are expressed. Step 6: To understand the indoor climate, the building physics are explored. Step 7. The climate specifications derived from step 3 to 5 are weighed and for each climate zone the optimal climate conditions are specified. Step 8: Within the value framework established in Step 1, the options to optimize the indoor climate are considered and selected. Step 9: All options to reduce the climate collection risks are evaluated by the objectives established in Step 1.

Alternatives in Refrigeration and Air Conditioning highlights the issues related to ozone layer depletion and global warming due to use of conventional cooling technologies and refrigerants in the field of Refrigeration and Air Conditioning (RAC). It describes, simulates and analyzes the alternate technologies and alternate refrigerants from energy and exergy point of view. The unconventional and alternative refrigeration technologies viz. Vapor Absorption Refrigeration, Vapor Adsorption Refrigeration, Evaporative Cooling, Desiccant Cooling, Thermoelectric Refrigeration, Thermo Acoustic Refrigeration, Ejector Cooling, Vortex Tube Refrigeration Systems and Metal Hydride Refrigeration etc. are explored in the subject matter of this book. The combined or integrated approach of some technologies to enhance the performance, waste heat utilization or to increase the arena of its use is also discussed. This book will cater to the needs of the RAC community from the point of view of feasible futuristic options in this area. This book will also serve as a text book for postgraduate students especially of thermal and energy engineering stream and useful to the teachers, researchers, and practicing engineers.

It's a contraption that makes the lists of "Greatest Inventions Ever"; at the same time, it's accused of causing global disaster. It has changed everything from architecture to people's food habits to their voting patterns, to even the way big business washes its windows. It has saved countless lives . . . while causing countless deaths. Most of us are glad it's there. But we don't know how, or when, it got there.
It's air conditioning.
For thousands of years, humankind attempted to do something about the slow torture of hot weather. Everything was tried: water power, slave power, electric power, ice made from steam engines and cold air made from deadly chemicals, "zephyrifers," refrigerated beds, ventilation amateurs and professional air-sniffers. It wasn't until 1902 when an engineer barely out of college developed the "Apparatus for Treating Air" a machine that could actually cool the indoors and everyone assumed it would instantly change the world.
That wasn't the case. There was a time when people "ignored" hot weather while reading each day's list of heat-related deaths, women wore furs in the summertime, heatstroke victims were treated with bloodletting . . . and the notion of a machine to cool the air was considered preposterous, even sinful.
The story of air conditioning is actually two stories: the struggle to perfect a cooling device, and the effort to convince people that they actually needed such a thing. With a cast of characters ranging from Leonardo da Vinci and Richard Nixon to Felix the Cat, Cool showcases the myriad reactions to air conditioning some of them dramatic, many others comical and wonderfully inconsistent as it was developed and presented to the world. Here is a unique perspective on air conditioning's fascinating history: how we rely so completely on it today, and how it might change radically tomorrow.

This book introduces magnetic bearings--mechatronic devices that produce contact-free electromagnetic force to support a load, such as a moving train or a spinning rotor. Compared to traditional bearings, magnetic bearings offer several advantages: no friction, low heat generation, no required lubrication, quiet operation, and fast and stable rotation. For these reasons, magnetic bearings have been used in rotary ventricular assist devices (VADs) to increase design life, reduce or eliminate material wear and bearing maintenance, as well as to increase biocompatibility by eliminating high fluid stresses and heat generation, both of which are associated with hemolysis, platelet activation and aggregation, and thrombus growth. The book covers the principles of these bearings, how they are used in integrated control and electronics systems, and useful information on several major brands of current assist devices.
