JP Series Jet Fans - For Car Park VentilationINTRODUCTIONPacific HVAC Engineering is able to offer a complete solution in car parkventilation at a competitive price in partnership with Elektrovent, oneEurope’s largest and most experienced fan specialists.Car Park Ventilation PrinciplesJet fan systems are active systems offering a cost effective solution toventilate and extract smoke and pollutants, for example Carbon Monoxide(CO), from car parks. This ductless ventilation system provides either normalventilation or smoke extract in case of emergencies, or a combination ofboth.An efficient system requires good planning, starting with the physicaldimensions of the cark park, considering the pattern of utilisation as well aspeak loads. Ventilation rates are mostly based on an air exchange rate, or ona rate multiplied with the number of parking spaces.A Jet Fan system offers the “ventilation on demand” principle for car parks,depending on measurements by CO sensors. Jet Fans can be individuallycontrolled, or grouped together in fire zones. In fire mode, after a pre-setstandstill escape period, the jet fans will run at full speed to quickly andeffectively clear smoke.BenefitsThe space saving design, compared to a standard duct based ventilationsystems, offers a variety of benefits:• It is possible to ventilate or extract smoke in particular sections ofthe car park. CO (carbon monoxide) and smoke sensors ensurethat only fans in polluted areas are activated and the fans areswitched into smoke extract mode immediately if a fire starts.• No expensive, bulky and complex duct systems, making it an idealsolution for renovations.• Car park design is more attractive.• Improved air quality in car parks compared to conventionalducted systems.• Optimum safety is provided in case of a fire in the car park. Rapidsmoke extraction, smoke cooling, limited smoke spread, i.e. bettersmoke control.• Jet Fan systems for smoke extract prevent costly consequentialdamages in case of a fire: the ceilings are subjected to less heat,and smoke is quickly removed from the building.• More flexible in re-positioning when the parking area is redesigned.• Energy saving in exhaust air fans due to reduced system resistance(no duct systems).• Reduced installation and running costs.BCA And The Requirements of AS/NZS1668.2The use of an appropriately designed Jet Fan system is deemed to meet therequirements of the Building Code of Australia (BCA) and comply withAS/NZS1668.2 provided there is evidence to support the efficacy of theinstalled system. Evidence of the system function and compliance isproduced in the form of computer generated models (Computational FluidDynamics Analysis) simulating air flows within the structure.2 © Pacific HVAC Engineering 2013 www.pacifichvac.com Tel.

JP Series Jet Fans - For Car Park VentilationINTRODUCTIONBCA And The Requirements of AS/NZS1668.2 (Continued)In order to perform a CFD analysis, it is essential to have a 3-Dmodel of the building site, giving all openings, slab height, surface of theceiling (flat or with drop beams, dimensioning of the drop beams, etc.)and all other details required to carry out a simulation.A CFD analysis is used to simulate the airflows, to ensure that the distributionof the air is sufficient to effectively ventilate the cark park under normalconditions as well as in emergency situations. The analysis references allaspects of the design of the structure and the emissions concentrationscalculated for the intended usage loads of the building. The CFD reportillustrates the number and placement of Jet Fans taking into account thebuilding design and structural obstacles.Pacific HVAC Engineering is able to facilitate the preparation of CFD Reportson a project by project basis. Costing is quoted taking into account the scaleas well as complexity of the project.Control SystemsA control system is required, which is tailored to handle the requirements ofthe specific project for ventilating and smoke extraction. An effective controlsystem saves energy by reducing the ventilation rate with the help of COsensors, depending on the car park usage, increasing ventilation rate only inpeak hours and operating the jet fans only selectively, according to demand.When used for smoke extract, the system has to work on a fire detectionsystem (heat or smoke detection). In car parks with different levels, thesystem has to run the jet fans full speed on the fire level, and simultaneouslyswitch off the fans in all other levels. The main exhaust air fans are switchedto full speed. The control equipment regulates the main supply and/orexhaust fans together with the jet fans, both depending on thesignals coming from the sensors.Note: Owing to the complex nature of control systems generally and moreprecisely the integration of ventilation and smoke control systems withBuilding Management Systems (BMS), Pacific HVAC Engineering is not able tofacilitate control system design for projects.JP CENTRY - SeriesLow Profile Centrifugal Impulse Fans.JP DUCT - SeriesAxial Impulse Fans.© Pacific HVAC Engineering 2013 www.pacifichvac.com Tel.
