Applications of smoke control methods

Figure 4: Sample HVAC operation during smoke control

Note:

For simplicity, Figure 4 does not show the ducts on each floor or the penthouse equipment.

When an HVAC system serves only one smoke control zone, the following sequence provides smoke control:

1.In the smoke control zone, the return/exhaust fan activates, the supply fan deactivates.

2.The return air damper closes, and the exhaust damper opens (optionally, the outside air damper closes).

3.In the no-smoke zone, the return/exhaust fan deactivates, the supply fan activates.

4.The return air damper closes, and the outside air damper opens (optionally, the exhaust air damper closes).

Stairwell smoke control

Stairwell smoke control uses pressurization to prevent smoke migration through stairwells to floors remote from the source of the smoke. Secondarily, it provides a staging area for fire fighters.

In the smoke control zone, a pressurized stairwell maintains a positive pressure difference across closed stairwell doors to limit smoke infiltration to the stairwell. Stairwell smoke control employs one or more of these design techniques: compensated pressurization, non- compensated pressurization, single injection pressurization, and multiple injection pressurization.

Compensated pressurization technique

The compensated stairwell pressurization technique adjusts air pressure to compensate for various combinations of open and closed stairwell access doors. The technique maintains constant positive pressure differences across openings. To compensate for pressure changes, it either employs modulated supply airflow or over-pressure relief.

BAS-APG001-EN, Engineered Smoke Control System for Tracer Summit specifications

The Trane Engineered Smoke Control System is an advanced solution designed to enhance safety and efficiency in buildings by effectively managing smoke during emergency situations. Specifically tailored for integration with the Tracer Summit Building Automation System, the Trane Engineered Smoke Control System (BAS-APG001-EN) combines cutting-edge technologies with user-friendly features, empowering facility managers to maintain optimal air quality and ensure occupant safety.

One of the standout features of the system is its programmable logic capabilities, which allow for customized smoke management strategies based on building layout and operations. This flexibility ensures that smoke is effectively controlled, providing clear egress paths for occupants while maintaining a safe environment for emergency responders. The system is engineered to operate seamlessly with other building systems, including HVAC and fire alarm systems, enabling a cohesive response during smoke events.

The Trane Engineered Smoke Control System employs sophisticated detection technologies that monitor air quality and detect smoke in real-time. This proactive approach facilitates early intervention, allowing for rapid activation of smoke control measures. Additionally, the integration of variable speed fans ensures that smoke is moved efficiently out of critical areas, reducing the risk of smoke inhalation for building occupants.

One of the key characteristics of this system is its ability to provide reliable, redundant operation. With engineered backup systems in place, the reliability of smoke control measures is significantly enhanced, ensuring that they will function correctly even in the event of a power failure. This is especially critical in high-rise buildings or complex structures, where smoke control is vital to occupant safety.

User interface features included in the Tracer Summit system offer intuitive controls and monitoring capabilities, simplifying the management of smoke control operations. Facility managers can easily view system status, receive alerts, and make necessary adjustments through the user-friendly dashboard, enhancing operational efficiency.

The Trane Engineered Smoke Control System stands out as a premier solution for smoke management in contemporary building designs. By integrating sophisticated detection technologies, programmable logic, and reliable operation, it provides an essential layer of safety in creating environments that prioritize occupant protection. As buildings continue to evolve, Trane’s commitment to innovation ensures that its Engineered Smoke Control System remains a key component in modern fire safety infrastructure.
