Classification of Duct Systems: An Expert's Guide

Ducts are an essential component of any air conditioning system, and understanding the different types of ducts available is essential for ensuring your home or office is properly ventilated. There are three main classifications of ducts: air conditioning ducts, recirculating air ducts, and fresh air ducts. Each type of duct has its own unique characteristics and benefits, and understanding them can help you make the best choice for your needs. Flexible ducts are the most common type of air conditioning ducts. They are constructed from a coil of metal wire covered with a layer of flexible plastic, and often have thermal insulation made from glass wool, polyethylene, or metallized PET.

Flexible ducts are ideal for tight spaces, as they can be easily moved from one side to the other. They also have the added benefit of dampening the sound of the air conditioner. Rigid-type ducts are similar to sheet metal ducts, but they have an internal or external fiberglass coating. This type of duct is preferred in commercial buildings and offices, as it offers superior sound dampening and improved airflow efficiency. Rigid-type ducts can also be lined with fiberglass, which helps to prevent mold growth. Semi-rigid duct systems offer the installer versatility to switch between round and oval ducts without losing hydraulic pressure or system performance.

This type of air duct is ideal for complicated spaces where it is impossible to install or use rigid ducts to connect non-flexible ducts to an air supply outlet. It's important to keep in mind that all types of air conditioning ducts require regular cleaning in order to maintain their efficiency. Cleaning your air ducts regularly will help ensure that your home or office is properly ventilated and that you're getting the most out of your air conditioning system.
