Car park ventilation system design

The following steps are sufficient to create an initial impulse ventilation system design. A Computational Fluid Dynamics (CFD) analysis is often required to prove and further refine the design. Fans may need to be re-orientate or in some cases, added or removed. An impulse ventilation system can be tailored to suit virtually any car park. With a combined experience and knowledge of car park ventilation , smoke ventilation and natural ventilation systems of over years, we will be able to provide the most suitable and efficient system to meet with your requirements.

Car park venting systems are required to exhaust pollutants produced by vehicles an in the event of fire, clear smoke to assist the fire service. Impulse ventilation systems move the air throughout the car park and ensure that the air goes where we want it to go, rather than where it would flow to if left to its own devices. For this article, i will only describe mechanical ventilation design.

Fan System design , allowing the most efficient design to meet the car park’s requirements. Extract rates can be varied by constant pollution monitoring. What regulations apply to the design of ventilation systems for underground car parks, and what guidance is available? We have considerable experience in the design and implementation of smoke control systems or smoke ventilation in car parks.

Colt offers the latest technology in impulse or induction ventilation systems , comprising of relatively small fan units positioned around the car park , eliminating the need for disruptive ductwork. Ventilation systems for car parks, loading bays and service areas are needed to achieve two objectives. Day-to-day ventilation is needed to control build up of vehicle exhaust fumes or spilled fuel when the facility is in general use. Smoke Clearance System 20.

Car park ventilation needs to provide both day-to-day air quality ventilation as well as deliver emergency smoke clearance in the event of a fire. A major threat to life in enclosed spaces is smoke. Delta Ventilation design , supply and install a range of industrial and commercial smoke air ventilation systems and louvres. In some cases, fans may be set off the ceiling through the use of brackets and anti-vibration mounts. The FläktGroup Thrust Fan System is one of the most efficient and cost effective car park ventilation systems available on the market today.

Both day-to-day pollution and emergency smoke are safely and effectively ventilated. Designed to the highest standards and meeting the most stringent criteria to ensure all design requirements are met. Any design guiddines should account for thi. Reversible jet fans are available and can be programmed to drive smoke in opposite directions dependant on the fire location. Computational Fluid Dynamics modelling and car park ventilation Computational Fluid Dynamics (CFD) is often used to help design complex smoke control systems and is a useful tool for predicting their performance.

ACH Download Free MEP Calculation Excel Sheets, AutoCAD Drawings, and Training Courses for HVAC, Firefighting, Plumbing and Electrical Systems Design. The product design eliminates the requirement for ducted systems , making efficient use of the limited space of enclosed car parks, in addition to reducing power consumption and the associated running costs. Car Park Ventilation System Design - Calculation Excel Sheet. In enclosed car parks, mechanical ventilation is necessary to keep the level of hazardous gases such as carbon monoxide (CO) to a minimum.

By using jet fans, these ventilation systems can be designed without the use of bulky ductwork. The small car park jet fans are strategically positioned and can ventilate large areas of the car park by means of induction. It helps maintain good air quality when the car park traffic is high and conserve energy when it is low, controlling operation of the fans according to the conditions in the space to save energy and will usually incorporate CO sensors and fans speed control. The first approach imposes a significant energy cost and the latter two can compromise occupant health and safety.

We are specialists in providing ventilation solutions to every type of car park including commercial, residential, fully or partially enclosed. CO Guidelines for the Design Engineer Detection and Control System 4. Ventilation Requirements A controller monitoring multiple CO sensors should be capable of zoning. The controller should have multiple relay outputs and thresholds in order to control exhaust fans, make-up fans and supply fans.
