Selection of type of an air terminal depends on lightning protection category of the structure. The standards fix three categories of lightning protection devices, depending on the explosion and fire risk, capacity, fire resistance and purpose of protected sites, as well as annual average duration of thunderstorms in the geographical area of ...

In the 1970s, two types of unconventional air terminals had been commercially re-invented4 and introduced in the world market. They are the lightning prevention air terminal and the lightning attracting air terminal. Only one un-conventional air terminal is usually installed centrally on the roof of a building

An air terminal, also known as a, lightning rod, franklin rod, finial, lightning protection mast, or air termination rod, is a pointed tip rod made from conductive material such as copper or aluminum and is positioned above all other metallic objects on a building or structure to provide external protection from direct lightning strikes.

Carrier's Axis™ air terminals provide a customizable and energy-efficient solution for your commercial building's HVAC system, with single and dual duct, fan-powered, and system-powered options available.

The purpose of this standard is to establish for Air Terminals: definitions; classifications; test requirements; rating requirements; minimum data requirements for Published Ratings; marking and nameplate data; and voluntary conformance conditions. 1.1.1 Intent.

Different types of air terminals cater to specific needs and building designs: Early Streamer Emission (ESE) Air Terminals: These advanced air terminals utilize a special technology to proactively attract lightning strikes, creating a protective zone around the structure.

For example, air-terminals (rods) may be required on a parapet edge and a good design will allow sufficient height so that protection is provided regardless of whether the rods are installed on top of the parapet, or on the inside or outside edge.

2024年12月16日 · Understanding the differences between these two types of air terminals allows stakeholders, including architects, engineers, and facility managers, to make informed decisions when implementing lightning protection systems.

2014年12月1日 · Four types of air terminals, including circular diffusers, square diffusers, perforated diffusers and double deflection grilles were studied by experimental and numerical methods. Human subject tests of thermal sensations and comfort were conducted under various experimental conditions.

2021年3月2日 · What are the different types of terminals? Several types of terminals include ring, spade, hook, quick-disconnect, bullet, butt terminals and flagged. Wire terminals are available in insulated and non-insulated.
