They often assist developers, architects, and building owners that are responsible for the building of a fresh building or home. There are several reasons for hiring a fire protection engineer that you ought to consider.

Good reasons to hire one of these experts – Here are the two premiere factors behind working with a fire protection engineer. First of all, you have to ensure the care of everyone that would ultimately be present at that structure frequently. Secondly, it is important to have many possible protections in position in case a fire occurs. Anything that they suggest will be counted on investors, and subsequently included in the specific building. If getting a fire protection engineer is the next step of your respective project, you can easily find several of them that can help you.

What Exactly Is The Concept Of Fire Protection Engineer in Graceland West Chicago?

The concept of fire protection engineer is simply the study of fire in terms of our built-up environment and the way architectural design sways the causes and spread of fire. Furthermore, this discipline of engineering involves using engineering principles (mechanical, chemical, electrical, and civil engineering), chemistry, physics, material science, technology to implement underlying fire suppression system that protects both humans and the property under consideration.

In connection with this, fire protection engineering can be a field and study that is involved in saving property and lives from disaster way before fire emerges. Fire protection engineers use their skill to impact just how the fire suppression system in the building happens. To this particular end, they may have input in the design of a building, materials employed in the erecting of the building, as well as the building layout. Essentially, a fire protection engineer may have input regarding fire discovery and suppression method used.

Their efforts guarantee that each time a fire arises, the suppression system works to control the fire effectively, allowing time for anybody inside the building to get out to safety. Moreover, the suppression system that is choosen should hinder the spread of fire, negating the potential of the fire spreading even more.

An MEP Engineers’ Guide to Air Dampers

HVAC Engineering Salary

An air damper is a device that uses valves or plates to stop or regulate the flow of air within a duct, chimney, variable-air-volume (VAV) box, air-handling unit or other similar pieces of equipment. Dampers are also used to stop airflow into unoccupied or unused rooms where air conditioning is not required. In addition, MEP engineers install dampers as protection measures against smoke or fire.

An air damper is a complex mechanism with many moving elements. Their main components are the blades, which adjust their position to control airflow. In addition, dampers include frames, linkages, axles, bearings, seals, blade pins, actuating motors, flanging, jackshafts, and sleeves, among other components.

Types of Air Dampers

Based on their construction, air dampers can be classified into parallel blade and opposed blade dampers. Each configuration has unique performance features and is intended for different applications.

1) Parallel Blade Dampers

In this type of air damper, blades rotate in the same direction, parallel to one another. The parallel blade configuration is typically used when the damper operates in two positions: open or closed.

These dampers redirect air flow along their first few degrees of rotation, as they move from fully open to closed, and therefore control is achieved along the first 20-30% of movement.  Rather than modulating air streams, these dampers change their direction, and that is the main reason why they are preferred for open-close operation or fixed flow control.

Parallel blade dampers are typically used by MEP engineers in applications where the damper represents a major portion of the overall system pressure loss. They should not be used upstream of critical components due to their uneven airflow.

2) Opposed Blade Dampers

In this type of air damper, blades rotate in opposite directions to one another, modulating airflow. These air dampers are mostly used when the system requires airflow control rather than open-close operation, but they can also be used for on-off service.

Opposed blade dampers are typically used in the following applications:

  1. When the damper doesn’t represent a major portion of the overall system pressure loss.
  2. Systems that are required to maintain an even airflow downstream from the damper.
  3. Ducted terminals.

Classification of Dampers by Control Method and Application

Air dampers can also be classified based on the control method they deploy and their intended application. Based on their control method, dampers can be either automatic or manual:

  • Automatic dampers are similar to automatic control valves in terms of functioning.
  • Manual dampers are adjusted manually depending on the required airflow, as implied by their name.

Dampers can also be classified based on their application, and the following are some of the main types:

  • Balancing dampers (volume dampers)
  • Face and bypass dampers
  • Fire dampers
  • Smoke dampers
  • Combined fire and smoke dampers
  • Gravity dampers (backdraft or barometric)
  • Mixing dampers
  • Multi-zone dampers
  • Round dampers
  • VAV boxes (variable-air-volume)

Note how dampers are not only used for air balancing in ventilation systems, but also for safety in fire protection applications.

Why Are MEP Engineers Concerned About Dampers?

Air dampers are an important element of MEP engineering design since their use is subject to code requirements. They should also be designed to minimize energy losses, through the prevention of heat exchange across them when in the closed position, all while maintaining the required pressure conditions in different spaces.

Air dampers are subject to the following codes and standards:

  1. National Fire Protection Association (NFPA) standards:
    1. NFPA 90A Standard for the Installation of Air-Conditioning and Ventilating Systems
    2. NFPA 92A Standard for Smoke-Control Systems Utilizing Barriers and Pressure Differences
    3. NFPA 101 Life Safety Code
  2. Underwriters Laboratories (UL) standards:
    1. UL 555 Standard for Fire Dampers
    2. UL 555S Standard for Smoke Dampers
    3. UL 555C Standard for Ceiling Dampers

The main locations where air dampers are required to meet code are the following: stair enclosures, elevator shafts, common corridors, mechanical rooms, fire-rated walls, exterior building walls, shaft enclosures, horizontal assemblies, and duct and transfer openings.

Air Dampers in Fire Protection Applications

The three main types of dampers used in fire protection applications are fire dampers, smoke dampers, and combined fire/smoke dampers. This section provides an overview of each type and its applications.

Fire Dampers

Fire dampers interrupt airflow through the duct automatically, restricting the passage of flames. To accomplish their function, these dampers are installed in ducts that cross fire-rated assemblies or fire-rated walls. They can be installed in both horizontal and vertical ductwork and can be of both curtain type and multi-blade type.

A fire damper has the following components:

  1. Sleeve
  2. Curtain blade
  3. Break-away joints
  4. Fusible link
  5. Access door to inspect the fire damper

All fire dampers are installed in the open position, with a fusible link. When the temperature in the ductwork exceeds a specified value, the fusible link melts and the damper gets shut off, either by gravity or by a spring. To guarantee they accomplish their function, fire dampers need to pass various tests.

Fire damper selection is based on three main factors: fire resistance rating, temperature, and operating range. Fire rating depends on the time span for which a damper will withstand the heat associated with a fire. For walls, partitions, and barriers with fire resistance rating of less than 3 hours, 1.5-hour fire dampers are used. For fire barriers rated for 3 hours or more, 3-hour fire dampers are used. This procedure ensures building code compliance, which requires that the fire resistance rating is maintained across the full area of walls, partitions, and floors.

The exceptions for the use of fire dampers are parking garages, kitchen exhaust ductwork, and dryer exhaust ductwork.

Smoke Dampers

Smoke dampers prevent smoke from spreading in HVAC systems that are designed to shut down automatically in case of fire, and they only have two positions: open and closed. These dampers are installed in a slotted duct section – they are installed whenever a duct penetrates a smoke partition or smoke barrier inside the building. They can be applied in passive smoke control systems, or as part of an engineered smoke control solution.

In passive systems, smoke dampers close and prevent the circulation of air and smoke through ducts or ventilation openings that cross a smoke barrier. On the other hand, in engineered smoke control systems, the spread of smoke is controlled by the building HVAC system or by dedicated fans that create pressure differences. Smoke dampers may be controlled by heat sensors, smoke sensors, fire alarms, or any other method that meets the design intent.

A smoke damper has the following components:

  1. Sleeve
  2. Smoke blades (parallel)
  3. Break-away joints
  4. Duct-mounted smoke detector
  5. Damper actuator
  6. Access door

It is important to decide which ratings are required for UL Listed fire dampers.

  • The SD-1320 and SD-1330 smoke dampers are UL/cUL leakage rated dampers, listed under the latest UL 555S standard.
  • SD-1620 smoke dampers meet UL Class II. Leakage is less than 20 cfm per square foot at 4 inch w.g. and at 350°F (177°C).
  • SD-1630 smoke dampers meet UL Class I. Leakage is less than 8 cfm per square foot at 4 inch w.g. and at 350°F (177°C).

Fire and Smoke Damper (Combined)

As implied by its name, this type of damper is a combination of a fire damper and a smoke damper, and it is installed in ducts that cross partitions rated as both fire and smoke barriers. This type of damper must be qualified under both UL555 and UL555S.

Selection of a combined fire and smoke damper depends upon 4 factors: fire resistance rating, leakage rating, temperature and operational ratings.

Combined fire and smoke damper applications include walls, floors, partitions required by the local building code.

For walls, partitions, and barriers with fire resistance rating of less than 3 hours, 1.5-hour fire/smoke dampers are used. For fire barriers rated for 3 hours or more, 3-hour fire/smoke dampers are used. Designers are usually suggested to pick a very low leakage category.

Conclusion

Air dampers have a wide range of applications, ranging from airflow modulation in normal operating conditions to providing a reliable barrier against smoke or fire during emergencies. However, code compliance is an important aspect to consider regardless of the application, so working with qualified MEP engineers is highly recommended.
