Emergency Smoke Extract Principles and Solutions troduction The mechanical ventilation systems shown in this catalogue resolve the problems connected to smoke extraction at high temperature and are the ideal solution for emergency extraction in case of fire. Potential Risks in Fire Situation release of gas and toxic substances causing eyes to water and consequent difficulty in escaping ashes can be suspended in the atmosphere leading to reduced or no visibility development of very high temperatures the increase of carbon monoxide and reduction of oxygen in the air (possibly leading to asphyxiation) Function and Advantages of Mechanical Ventilation in Case of Fire 1. Mechanical ventilation removes smoke and fumes produced by a fire and by creating negative pressure (in the ambient) it prevents smoke spreading into other parts of the building. This makes it easier for people to escape and simplifies the job of the fire and rescue services. 2. enclosed areas, temperatures can easily exceed 1000 C, causing combustion from heat radiation and mak ing any external extinguishing opera tion useless. Keeping the tempera ture relatively low (300-400 C) by extracting hot air, can avoid the collapse of support structures. addition, the higher oxygen levels will cause better combustion and thus, for most materials, a lower production of toxic smoke. 3. Mechanical ventilation allows the siting of the exhaust outlets away from the fire. High temperature axial fans are easily connected to a duct system. 4. Mechanical ventilation allows the extraction of cold fumes, which since they remain at a lower level are dangerous and are difficult to remove using static systems. 5. Mechanical ventilation allows for ventilation in normal circumstances (clean air), using products with two speed motors: at low speed for normal ventilation (so with lower noise level) and at high speed for emergency conditions. For this type of operation, it is necessary to install the fan with a dedicated power line that automatically operates in case of fire. Certification Emergency Smoke Extract fan design and installation is regulated by the European standard EN12101-3, which establishes the temperature ranges/operation time certified products must comply with. The SMOKEX range is CE certified to classes F300 and F400 and guaranteed to operate at 300 C for two hours in compliance with EN12101-3 standard by the Applus laboratories in Barcelona. Page 3

Car Park Ventilation Principles and Solutions Basic Principle The ventilation of enclosed or underground car parks demands certain key fundamentals: the removal of pollutants emitted by vehicles the control and removal of hot fumes and gases in the event of a fire the effective protection of escape routes (which also provides easier access for Emergency Services) Special Technology recent years, the jet or induction fan technology has become the new standard for normal ventilation and for smoke extraction in case of fire in enclosed car parks. This technology represents the most innovative and cost-effective alternative to traditional ducted mechanical extraction systems. The careful management of the project in all its development stages (requireing the use of fluid dynamics calculation programs) ensures that the system will operate efficiently and correctly. Car park ventilation systems provide either normal ventilation to remove fumes and other pollutants, or can extract smoke at very high temperatures should there be a fire in an underground car park. Or they can be combination of both, i.e. dual purpose fans. tegrated Systems A fully integrated car park ventilation system requires five key elements: suitably positioned carbon monoxide (CO) and heat/smoke sensors a system control panel CFD (computation fluid dynamics) analysis accurate selection and positioning of smoke control fans contaminated air removal system. LCA-JT/HT or JTCHT CAHT Normal Ventilation The axial impulse or centrifugal induction fans efficiently ventilate both bottom and top layers avoiding the creation of areas where air could get trapped. The fans are only operated when the CO (carbon monoxide) detectors show a level of pollution higher than the pre-set level (variable according to requirements). Normal Ventilation Emergency Smoke Extract A fire starts The ventilation system starts to operate LCAHT LCA-JT/HT - axial impulse fans for car park ventilation JTCHT - centrifugal induction fans for car park ventilation The system is based on placing a set of axial impulse fans or centrifugal induction fans throughout the parking area, which operate in a similar way to a ducted system. When installed on the ceiling, they transfer the smoke-laden air from the upper to the lower layers, creating a continuous air flow, inducing cleaner, cooler air which drives the smoke to the extraction and removal points. The system is completed by natural or mechanical air inlets and exhaust fans. The smoke is extracted Page 31

Car Park Ventilation Principles and Solutions Advantages A smoke and fume extract system based on impulse axial or centrifugal induction fans can easily be split into different control areas. This ensures maximum extraction of smoke from the area where fire has broken out and increased the air pressure where the fire needs to be extinguished. Pressure is lowered at the site of the fire, stopping fumes spreading, and reducing the temperature of the fire affected area. Compared to a ducted ventilation system, this innovative system ensures multiple benefits in terms of the low cost and efficiency associated with its design, installation, operation and usage. Design The compact size of the fans and the flexibility of installation allows the optimisation of space. Design time is saved since there is no need for a complex ducted system. The system effectiveness can be pre dicted with CFD (fluid dynamics cal culation) modelling. It allows the project designer to benefit from a better pre-sales customer service. The project can be financially assessed within 24 hours to make sure that the final costs are in line with ex pected costs. stallation The fans are easy to install, ensuring time saving in terms of hours of work. There is no need for an expensive and complex duct and grille systems. The smaller sizes of the fans adds to the ease of installation of other services (sprinklers, lighting etc); The fans and systems are easy to maintain and service. Operation Major savings in running costs are ensured by the system's distinctive features: The ventilation system can be fully or partly operational. Carbon monoxide (CO) detectors and the smoke sensors, ensure that only those fans operate which are located in areas where pollution levels are exceeded or where a fire has started. Less total power required as the ac curate design ensures the optimal size of the ventilation system. The inlet and exhaust fans can be smaller as the jet or induction fans generate a negligible pressure drop compared to ducted systems. Use Better quality of breathable air: this system creates a continuous air flow mixing different layers of air and avoiding areas of trapped air. Optimised safety in the event of a fire: fast and effective toxic fume extraction, leading to safer escape routes, easier access for emergency services, promoting people safety and minimising the effects of fire on the building structure. From Design to Customer Service Designing a car park ventilation system requires the application of CFD. The high complexity and reliability of fluid dynam ics calculations are well established. During this crucial design stage, we can offer a full CFD analysis and valuable engineering support. How it Works CFD calculation is essential to ensure that all areas of the car park are correctly ventilated and, in the event of fire, fume extraction is optimised. CFD analysis is also necessary to calculate accurately the size of the ventilation system required together with the correct positioning of the jet or induction fans and of the other exhaust and/or inlet fans. This calculation is based on computer simulation and combines variables such as the required number of air changes/hour (as required by regulation), air volume and direction, and the structural features of each car park (in a 3D model). The data generates dynamic scenarios based on air speed profiles, particle movement and airflow distribution. This allows a customised ventilation scheme to be designed. This methodical approach allows not only prediction of the system effectiveness, but also ensures the most cost-effective solution. Page 32

Car Park Ventilation Principles and Solutions Calculation Set-up and Scenario Development Account must be taken of boundary conditions and initial conditions such as external pressure and outside air temperature. Structural parameters (light wells, access ramps etc) also need to be specified, together with operating conditions (material definition, assignment of air performance required). Mesh definition is also necessary (ie the quantity of primary volumes the model must be split into). Data processing and assessment of each scenario can be made by changing the type, quantity and position of the fans. Final Scenario During this last stage, the computer programme analyses the system effectiveness. Analysing Results and Developing a Balanced Solution Data can be analysed by checking the air speed inside each section of the car park. The graph shown below represents the average air speed on a sectional floor. Page 33

The presence of the pod gives higher noise attenuation, but creates an additional pressure drop in the system. Both the versions can be fixed to the corresponding flange of the fan in inlet and outlet. The LCS range does not create additional loss, but the LCSP versions do. Silencers can be in lengths equal to 1, 1.5 or 2 times the diameter (b). The silencers are manufactured completely in galvanized steel. The internal part and the pod are made in perforated sheet, to allow effective sound absorption of the acoustic lining in mineral wool. The working temperature is from -40 C and +150 C. Page 37
