Pressurisation

Full integrated smoke management system includes the following systems:

✓ Pressurisation ✓ Smoke Extraction System ✓ Car Park Ventilation System ✓ Smoke Control Solutions

5NAFFCOFlow.com

Pressurisation

PRESSURISATION

A pressurisation system consists of three main components: ✓ Supply Air (where air is injected into the area that is to be protected), ✓ Pressure Relief (to avoid overpressure when doors are closed) ✓ and Air Release (air and smoke is released from the adjoining fire area).

Combining these elements creates a positive pressure difference that prevents lobbies and staircases from filling up with smoke.

A pressurisation system for smoke and fire ventilation should meet the recommendations of: ✓ BS EN 12101-6 “Specification for Pressure Differential Systems” or BS 5588-4 - “Code of practice for smoke

control using pressure differentials” ✓ NFPA ✓ Other international codes of practice ✓ and Local authority regulations.

The System Comprises:

Inlet Fans for introducing air into the designated

area. The run and standby fans and

control equipment should be housed in a

separate plant room or outdoors and the inlet should be protected from smoke.

Automatic air release to prevent unwanted

pressure build up in the adjacent spaces.

This may be automatic vents, natural shafts or

mechanical extract systems.

Ductwork and Outlet Grilles, to provide

distribution of air.

The control system should operate

automatically from the smoke detection

system with a manual on/off switch.

Pressure relief dampers, to release excess air

in the closed door condition from the stair

area.

Pressurisation SystemWhat We Offer

7NAFFCOFlow.com

System Requirements:

There are three requirements to maintain within a pressurisation system.

Design Methodology:

✓ Assess the usage and layout of the building, the area to be pressurised and the class of system required.

✓ Assess the leakage paths (through doors, lifts, vents). ✓ Calculate the required volume flow rates. ✓ Calculate the area of pressure relief dampers. ✓ Calculate the area of air release ventilation.


Maintaining a pressure difference for a closed door condition.

Maintaining a velocity for an open door condition.

Right balance is required in a pressurisation system. Insufficient pressure difference across a closed door will allow the passage of smoke into the protected space. Excess pressure will impede door opening and hence escape.

8NAFFCOFlow.com

What We Offer

1. Staircase Pressurisation

The stairwell pressurization serves several purposes: ✓ Inhibit migration of smoke to stairwells, areas of refuge, elevator shafts, or

similar areas. ✓ Maintain a tenable environment in areas of refuge and means of

egress during the time required for evacuation. ✓ Facilitate the fire and rescue operation by improving visibility

in the building for the fire-fighting crew. ✓ Facilities egress evaluation.

Pressurisation System

2. Lift-Shaft/Lift-Well Pressurisation

3. Lobby Pressurisation

Elevator shaft pressurization is required to protect the shafts from ingress of smoke. Thereby, it restricts smoke spread to other floors connected to the shaft.

Lobby pressurization based ventilation systems are pervasively used to ventilate mid-rise to high-rise multi-unit residential buildings. This system uses a make-up air unit (MAU), usually located on the roof of the building, to draw fresh air in with a large fan either continuously or on a pre-set schedule. Once the air is drawn into the building, it is distributed to each floor through a large vertical duct usually located in the building core.

Car ParkVentilation

Car Park VentilationWhat We Offer

INTRODUCTION

Special Technology

In recent years, the technology used for jet (or impulse) fans has been established as the new standard for normal ventilation and smoke extraction in case of fire in enclosed car parks.. In fact, this technology represents the most innovative and cost-effective alternative to traditional ducted mechanical extraction systems.

The ventilation of enclosed or underground car parks, loading bays and service areas fulfils two key requirements: remove the pollutants emitted by cars and, in the event of a fire, control the hot fumes and gases produced by the fire, protecting the escape routes and easing access for the emergency teams.

Car park ventilation systems are designed as per following codes of practice: ✓ BS 7346 Part 7 ✓ NFPA 88A ✓ NFPA 92 ✓ Other International Codes of practice ✓ Local Authority Regulations

Smoke ventilation systems may be designed in addition to provide clear smoke-free access for fire fighters to tackle the seat of the fire or to protect means of escape from the car park.

15NAFFCOFlow.com

System Description

Design

The fully integrated JET FAN includes 6 elements, ✓ Main Smoke Exhaust Fans ✓ Fresh Air Fans ✓ Jet Fans ✓ CO Sensors ✓ System Control Panels ✓ Starter Panels ✓ DDC Panels

These are the essential requirements to design the most suitable Smoke Management/ventilation system for a specific car park.

The system is based on placing a set of axial impulse fans (JET FANS) all along the parking area, which operate in a similar way to a ducted system: when installed on the ceiling, they move the air from the top layers to the bottom layers towards the exhaust areas; by effectively creating a continuous air flow, the JET FANS are able to thoroughly push the air at the bottom and the top layers of the car park, avoiding the creation of areas where air gets trapped.

✓ It saves design time as it does not require a complex ducted system to be designed and implemented.

✓ The system effectiveness can be measured with CFD (Computational Fluid Dynamics) modelling.

Compared to a ducted ventilation system, the innovative JET FAN system ensures multiple benefits in terms of low cost and efficiency associated with its design, installation, operation and usage.

Installation

Benefits

Use

✓ It removes the need for costly and complex ducted and grilled systems.

✓ The fans are easy to install, ensuring time saving in terms of hours of work.

Enclosed or underground

car parks normally require

ventilation systems to assist

fire fighting operations.

These systems generally

also prevent the build-up

of carbon monoxide during

normal day-to-day use of

the car park.

Ventilation can be fully or partly operated: the CO (carbon monoxide) detectors and the smoke sensors ensure that the ventilation located in the parking zones control the pollution levels or signals at the event of fire.

✓ Optimized safety in the event of a fire: fast and effective toxic fume extraction, leading to safer escape routes, easier access for the emergency teams, promoting people safety and minimizing the effects of fire on the building structures.

Main Components

1. System Control Panel

Control panel is responsible for the operation of all the mechanical equipments (axial fans, jet fans, smoke/ air dampers, doors etc.) of the system in compliance with the scenarios identified to PLC (Programmable Logic Card), according to the signals coming from all carbon monoxide sensors and/or fire/smoke detection systems.

3. Jet Fans (In Floor Ceilings)

Jet fans are responsible for circulating air through all the sections of car park by moving air in small volumes in high velocities through the exhaust shaft and consequently creating a low pressure area near the ceiling of the car park.

2. Fire Rated Duct

Ducts are utilised as a part of heating, ventilation, and air conditioning (HVAC) to deliver and eliminate air.

Ducts are rated as per the local regulations and international codes of practice. These ducts facilitate movement of Smoke/Fresh Air/Exhaust Air as desired by the ventilation system

18NAFFCOFlow.com


5. Motorised Smoke Dampers

Motorised smoke dampers are installed in duct work to achieve desired sequence of opening in an event of fire.

4. Axial Fans (For exhaust and/or fresh air requirement)

Main duty of the axial fans is the discharge of polluted air and/or fire smoke from the car park and supply of fresh air from outside required for the car park. Capacities and power values of axial fans are calculated according to the exhaust and fresh air flow rates specified by local car park fire and ventilation codes.

6. Sound Attenuators

Sound absorbers are responsible for reducing the noise generated by main axial fans to the desired NC levels. They are located in inlet and outlet of axial fans.

19NAFFCOFlow.com


Detection Accessories which ensure Smooth Operation of Ventilation System:

1. Fire/Smoke Detection System

Thanks to fire/smoke detection systems, it is possible to immediately detect fire or a smoke source in car parks and put fire safety systems into use. Sensors are distributed and addressed in car park according to the related codes.

2. CO Detection Systems

By means of CO detection systems, air pollution inside car park can be measured at any time. In line with these measurements, ventilation system works in various capacity levels as per the need.

3. FIRE & SMOKE CURTAINS

A Fire Curtain in a building creates a fire-resistant barrier which protects and separates a part or a section of the building from fire or smoke damage in the event of a fire mishap. The Fire Curtain is a part of fire safety measure, it is either fixed or it automatically drops and separates the area when activated by fire.

Compared to a Smoke Curtain, it includes a coated glass fabric with stainless steel wire insert as an additional safety measure to offer protection from sudden impacts and to with stand a fire resistance temperature of 1100˚C for 120 minutes or more of fire exposure.

A Smoke Curtain in a building will guide the smoke which consists of gas and small particles send into the air by burning materials to an extraction system within the building and effectively protect people from the exposure to dangerous smoke as well as limits the damage and further spread of fire.

A fixed Smoke Curtain or an automatic Smoke Curtain separates an area and keeps the smoke from spreading from one area to another. Silicone or PU coated woven glass fabric is used as a standard material to withstand a fire resistance temperature of 600˚C for 60 minutes of exposure to fire.
