Boken är ett komplement till handboken 'Praktiska lösningar Brandskydd ventilation', som gavs ut av Svensk Ventilation i samverkan med Energi- och Miljötekniska Föreningen 2004.
I modern husbyggnadsteknik har det blivit allt vanligare med skyddsmetoder där värme, rök och brandgaser förs bort från byggnaden mekaniskt i händelse av brand. Många brandskydds-tekniska lösningar innehåller därför särskilda brandgasfläktar vid tillämpning av dessa metoder.
Denna handbok behandlar både teori och praktik kring detta ämne. Den riktar sig till projektörer och andra aktörer inom VVS-, brand-, el-, styrområdena m fl. Syftet med boken är att ge läsaren möjlig-heten att både bredda och fördjupa sina kunskaper i ämnet och på så sätt bidra till att brandtekniskt säkra byggnader skapas.
I boken redovisas beprövade lösningar på många vanliga brandskyddstekniska problem ventilationssammanhang. Naturligtvis har den inte en lösning på varje tänkbart problem. De lösningar som redovisas är inte heller de enda möjliga ett givet fall. Men urvalet är gjort så att det skall täcka de allra flesta vanliga installations-situationerna, och därmed vara ett värdefullt arbetsredskap för dem som projekterar eller leder byggandet av ventilationsanläggningar.
Huvudförfattare till boken har varit Olle Cronberg på uppdrag av branschorganisationen Svensk Ventilation. Värdefulla synpunkter på uppläggning och innehåll har lämnats av Svenska Brandförsvars-föreningen (SBF) och teknikgruppen Brand inom Energi- och Miljötekniska Föreningen.

En byggnads termiska funktion bestäms av hur värme strömmar mellan byggnaden och dess omgivning, i byggnads-konstruktionen och mellan byggnadens innerytor och rumsluft. De klimat-styrande installationernas funktion i klimatsystemen för värmning, ventilation och kylning, som i slut-änden säkerställer det önskade inneklimatet, bygger i stor utsträckning på hantering av värme-strömmar i värmeväxlande komponenter
När Energi- och Miljötekniska Föreningen nu firar sitt 100-års jubileum känns det angeläget att i bokform dokumentera den gedigna och imponerande historia som föreningen med stolthet kan titta tillbaka på.

Research, development and use of displacement ventilation, mainly confined to Scandinavian countries, is now gaining popularity in other countries as well.
The guidebook serves as a comprehensive and easy-to-understand design manual. The book explains the benefits and limitations of displacement in commercial ventilation and outlines where ventilation should be applied. Case studies for a restaurant, office cubicle, auditorium, meeting room and classroom are included.
With displacement ventilation, warm contaminants rise to the ceiling, the contaminated air is extracted and fresh, cool air is supplied at floor level. Displacement ventilation has two main advantages over traditional mixing systems. First, it ensures improved indoor air quality throughout occupied spaces and removes more contaminants at high level than conventional mixing air distribution systems. Second, as an efficient use of energy due to its capability to remove exhaust air from the room at a higher temperature than that in the occupied zone, this strategy allows a higher inlet temperature for the same internal heat gain/load. Benefits are that less cooling is needed for a given temperature in the occupied spaces, longer periods with free cooling and better air quality in the occupied spaces.
The book also points out the limitations of displacement ventilation. The technique is no marvel that can solve all ventilation problems, but a principle that has definite advantages when applied correctly.
Ventilation effectiveness is the common notion for the indices used to characterize the ability of a ventilation system to exchange the air in the room and the ability of a ventilation system to remove air-borne contaminants. Improving the ventilation effectiveness allows the indoor air quality to be significantly enhanced without the need for higher air changes in the building, thereby avoiding the higher capital costs and energy consumption associated with increasing the ventilation rates. This guidebook does not only present the practical research on ventilation effectiveness, but also illustrates its application with case studies.
This guidebook is aimed at practising, consulting and contracting engineers. It provides easyto- understand descriptions of the indices used to measure the performance of a ventilation system and which indices to use in different cases. It also demonstrates how to measure ventilation effectiveness in practice. Use of tracer gases, measurement equipment and how to perform measurement and calculations are introduced. Eight practical case studies are also presented and discussed.
An Electrostatic Precipitator is a device that collects particles from air or flue gas by electrostatic forces. he ESP’s discussed in this book are all for industrial processes. Indoor small units for purification of ambient air are not covered. In the early days ESP’s were developed for recovery of precious material, e.g. Cu, Ni and Zn. Environmental aspects are however the main focus today. This guidebook is aimed at the practising, consulting and contracting engineers. It provides basic knowledge of the physics and power supplies of Electrostatic Precipitators (ESP’s), practical aspects of ESP design, and examples of typical applications of ESP’s. ESP’s are characterised by low-pressure drop and very high capture efficiencies and very low power demand. They can be built for operation at high temperatures, 400 °C and above with help of special steel. Today’s environmental egislation requirements are specified as emissions in terms of e.g. mg/Nm³ of flue gas rather than collecting efficiency.
Extremely low emissions can be guaranteed for most ESP applications today. The future will see even lower emission guarantees and for many applications the ESP will remain as an important device for the removal of particulate from flue gases.
The topic of guidebook on ventilation and environmental tobacco smoke is extremelyimportant in respect of indoor air quality, health and energy consumption. REHVA realises that the best protection against the environmental tobacco smoke is to ban the smoking indoors.
But if the smoking is allowed indoors, like it is in many countries, the ventilation can be effectively used to reduce the exposure to the environmental tobacco smoke. The purpose of this guidebook is present the state-of-the-art technology of controlling the nvironmental tobacco smoke indoors. The guidebook presents latest ventilation technology and illustrates the use of the technology with several practical examples for application. The book is intended for the designers, installers, architects, restaurants and building owner. With its illustrations it is an excellent textbook also for the vocational training.
Chilled beam cooling is relatively new technology that has rapidly spread all over the Europe. Its advantagesare in low noise generation, low room velocities and flexibility. High temperature level of cooling media also improves the energy efficiency of the mechanical cooling and allows longer periods of free cooling.
The guidebook presents theory on the principles of chilled beam cooling and illustrates its practical applications. The chilled beam systems are primarily used for cooling and ventilation in spaces, where good indoor environmental quality and individual space control are appreciated and where the internal moisture loads are moderate. Chilled beam systems are dedicated outdoor air systems. They can also be used for heating. Active chilled beams are connected to the ventilation ductwork, high temperature cold water and when desired low temperature hot water system. The main air-handling unit supplies primary air into the various rooms through the chilled beam. Primary air supply induces room air to be recirculated through the heat exchanger of the chilled beam. In order to cool or heat the room either cold (14–17 °C) or warm (30–50 °C) water is cycled through the heat exchanger. Recirculated room air and primary air mix prior to diffusion in the space. Room temperature is controlled by regulating the water flow rate of the heat exchanger.
How to integrate productivity in life-cycle cost analysis of building services
This REHVA guidebook shows for the first time how to quantify the effects of indoor environment on office work, and also how to include these effects in the calculation of building costs. This is a concerted effort of researchers, engineers and ractitioners. Such calculations have not been performed previously, as very little data was available on this issue. In recent years more and more information has become available on this topic. This information has been reviewed during the present work to find out whether there is solid scientific evidence that the indoor environmental quality affects office work.
The quantitative relationships presented in this guidebook can be used to calculate the costs and benefits of running and operating the building, as illustrated by several examples. One of the aims of these examples is to emphasize that the costs of running the building are much lower than the benefits from improved office work obtained by reducing temperatures or improving of indoor air quality. This is further presented in the guidebook by comparing the typical costs of wages, and typical energy and operation costs. The main purpose of the guidebook is to increase the awareness of building owners and practitioners to indoor environmental quality and its importance for office work. This is attempted by showing how large profits can be obtained from fairly small investments. Examples on how to convince the client in practice are given.
The guidebook describes the systems that use water as the heat-carrier and where the heat exchange within the conditioned space is more than 50% radiant. Radiant ceiling panels are suspended under the ceiling with heat carrier temperature relatively close to room temperature. Embedded systems insulated from the main building structure (floor, wall and ceiling) are used in all types of buildings and work with heat carriers at low temperatures for heatin and relatively high temperature for cooling. Finally systems with pipes embedded in the building structure (slabs, walls), which are operated at heat carrier temperatures very close to room temperature and take advantage of the thermal storage capacity of the building structure.
Using a low water supply temperature (of 25 – 40°C) in heating conditions and high water temperature (16 – 20°C) in cooling, allows the possible use of renewable energy sources. In cooling conditions it is also possible to use renewable energy sources, for example ground heat exchangers or rain water ground accumulators.
The guidebook describes the following systems: • Radiant heating and cooling panels • Pipes isolated from main building structure • Thermo Active Building Systems (TABS)
A growing body of evidence shows that indoor environmental conditions substantially influence ealth and productivity. Ventilation is an important contribution to air quality. Its purpose is to maintain good indoor air quality. But air handling systems may also be a source of pollution if not properly constructed and maintained.
This guidebook presents criteria and methods on how to design, install and maintain clean air handling systems for better indoor air quality. The ventilation system should be cleaned according to a cleaning plan. The plan consists of a selection of methods suitable for the different components and surface materials. The methods should be selected so as to avoid damage to surfaces and components being cleaned. The guidebook is useful for practitioners who like to follow the recent international practices. With its illustrations and examples it is also an excellent text book for the vocational training of various building professionals.
The guidebook offers a wide approach to the factors affecting indoor air quality and is aiming to conform to the European standards of HVAC system maintenance.
This Guidebook is intended to provide a holistic formulation of hygiene-related constructional, echnical and organisational requirements to be observed in the planning, manufacture, execution, operation and maintenance of ventilating and air-conditioning systems. These requirements for ventilating and air-conditioning systems primarily serve to protect human health; they may, however, also be the consequence of technical conditions.
The guidebook complements the REHVA guidebook no 8 Cleanliness of ventilation systems, published at the same time. The guidebook is based on VDI Guideline 6022, one of the most popular Guidelines published by VDI. Since 1998, more than 10.000 copies of VDI Guidebooks have been printed and thousands of people went to the training described in the guidebook. As the result the hygiene standard in air-conditioning systems today is much better than 10 years ago. REHVA´s Swiss member SWKI accepted the VDI 6022 Guideline as SWKI-2003-5, in 2003. The REHVA working group revised and updated the German Guidebook with some new ideas and procedures.
Both the development of CFD models for room air movement and progress in the general fluid dynamics research are strongly influenced by the increased computer power that has been available for the past few decades.
This guidebook is written by a working group of highly qualified international experts representing research, consulting and design. CFD-calculations have rapidly been developed a powerful tool for the analysis of air and pollution distribution in various spaces. However, the user of CFD-calculation should be aware the basic principles of calculations, and specifically the boundary conditions. The reliability of the results depend very much on the skills of the person who performs the calculations.
Guidebook is intended for users of CFD-programs, designers, manufactures and building owners. It gives also guidelines for those who order CFD-calculations from the experts. With its illustrations and examples it is also an excellent text book for universities and also the vocational training of various building professionals.
