smoke control fans applications

smokecontrol
Shopping Centres & Public Buildings: Safe Escape
The main benefits of installing NuAire Smoke Control Systems are: • Safe escape for occupants • Safe entry for fire fighters • Reduced smoke damage • Reduced water damage NuAire fans provide a smoke ‘clear layer’ to allow building occupants to safely escape from a building during a fire situation.
Reservoir Screen Clear Layer Fresh Airflow Fresh Airflow Safe Means of Escape

Commercial & Industrial Buildings: Safe Escape & Protecting Goods
In addition these systems allow fire fighting services to safely enter the building, to locate the fire and maintaining a clear layer helps prevent ‘fire damage’ to stored goods or machinery.

High Temperature Fan/Cowl Combination

Pressurisation of Escape Routes
BS5588 Part 4: specifies the use of pressurisation for the means of escape. The systems ensure that stairs and corridors in mulit-storey buildings remain clear of smoke. BS5588 Part 5: specifies the use of pressurisation for fire fighting systems. In addition to providing safe means of escape, these are designed to offer safe access to fire fighters. Nuaire pressurisation run & stand by fans are specially designed to meet the requirements of these standards.

How the system works
The car park impulse system is used to control and remove contaminants on a day to day basis, whilst ensuring that smoke is removed quickly and efficiently in the event of a fire. The systems utilises a number of strategically positioned impulse fans, mounted on the ceiling, that push the fumes and smoke towards a designated point of exhaust. This in effect compartmentalises the smoke stream ensuring quick and effective clearance whilst keeping the rest of the car park smoke free. This removes the need for complicated ductwork systems and optimises space.

The system runs at low speed ensuring that Carbon Monoxide levels and other contaminants are kept within acceptable limits. Strategically placed detectors monitor the air and control the units which can directly effect the condition.

Smoke detectors throughout the car park identify the units which can most effectively contain the smoke layer and increases the fan speed to maximum, the main exhaust unit is also switched to maximum.

4

A fire starts in one of the vehicles and smoke starts to spread throughout the car park, the smoke detection system identifies the situation and the fire alarm system will be activated.

Car Park Impulse Fan Key:
Low speed/day to day High speed/smoke mode Main exhaust/extract unit, low speed/day to day

The smoke layer is contained and directed towards the main extract unit, where the smoke can be safely exhausted to atmosphere. This maximises the space within the car park, keeping large areas clear of smoke, enabling the area to be quickly and safely evacuated.

Car park impulse system specification

Complete solution for car park ventilation
Airvent Systems have over twenty years experience in the smoke ventilation industry and their project managers were instrumental in establishing the first Car Park impulse system in the UK, designing, installing and commissioning the system Airvent systems utilise the latest computer aided design, computational fluid dynamic technology and extensive testing, to master the physics and behaviour of fires within buildings. By understanding the movement of the fire and smoke and combining that with the knowledge and expertise of fire engineering, ventilation and containment principles, Airvent are capable of designing bespoke smoke ventilation systems to protect any building and its occupants whilst providing safe, healthy, clean and welcoming car parks. Airvent offer; • • • • • • • • • Conceptual design UK’s largest sales engineer network Dedicated technical in-house support team Regulatory compliance/co-ordination Onsite liaison Installation Commissioning Maintenance Whole life support facility

The car park ventilation system shall control and remove pollutants, such as Carbon Monoxide, on a day to day basis, whilst ensuring that smoke is removed quickly and efficiently in the case of fire. The car park Impulse Ventilation System shall consist of a number of strategically positioned acoustically treated Impulse fans distributed throughout the car park, the positions shall be in accordance with the specialists design & layout drawings. Carbon Monoxide & smoke detectors shall be strategically placed in accordance with the specialists design and shall control the operation of the impulse fans in individual areas appropriately. By controlling the fans in this way the impulse fans will contain pollutants and smoke within a defined & predetermined corridor and channel its flow to the extract point where it can be evacuated safely to atmosphere by the main exhaust fan unit. The control system ensures that only the fans that can directly effect the ventilation requirement are in operation. The Nuaire SVT impulse unit comprises a high temperature axial fan with specially designed inlet and outlet attenuators which, along with the fan unit, are encased in a Galvanised steel acoustic enclosure. The Nuaire SVT unit comprising fan/motor assembly, and inlet & outlet silencers shall be certified for high temperature operation at 3000C for 2 hours, the range shall have been type tested to EN12101-3.The Axus Main exhaust unit and ancillaries shall have been type tested and certified for high temperature operation at 3000C for 2 hours to EN12101-3. The units shall be either 2 speed or inverter driven providing, low speed for day to day environmental extract and one off operation for emergency extract. They shall also be suitable for reversible operation. Fully reversible options (i.e similar duty in both airflow directions) are available, please contact Nuaire for details. The unit shall have a unique mounting bracket, which shall enable the bracket to be positioned as a “first fix” component with the unit being fitted as a “second fix” component, avoiding possible mechanical damage. The Nuaire SVT unit shall have inlet guards for safety purposes and also to prevent debris being sucked through the fan. It also has a specially designed airflow deflector to direct the jet stream from the fan at the required angle sufficient to overcome the natural buoyancy effect of the smoke. The car park impulse units shall be the SVT type and the main Exhaust unit shall be the high temperature AXUS type all as manufactured by Nuaire.
