The Different Types of Air Ducts for Air Conditioner

We’ve looked at the compressors and compressors used in central air conditioning. A duct is a channel that transports cooled air from your air conditioner throughout your home. Heating and filtering systems can use the ducts used for central air conditioning. Let’s have a look at some of the different types of ducts required for air conditioning as well as what is Ducted Air Conditioning.

Knowing what you’re doing with your ductwork or what is ducted air conditioning?

To begin, you must first understand what a duct is. Ducts are channels that carry chilled air from your air conditioner throughout your home while also removing warm or stale air. Ducts used for air conditioning systems can also be used for heating and filtering.

When it did come to an HVAC system, we tend to neglect ducts, despite the fact that they’re one of the most important components that play a critical role in keeping us comfortable, whether it’s hot or cold. The air ducts are in charge of distributing cooled or warmed air throughout the building’s rooms. The rest of the HVAC system would be useless without an air duct. There are a variety of duct systems that can be used in either a residential or commercial setting. While it is not necessary to know everything there is to know about all the duct systems available on the market, it would be beneficial if you did. It will undoubtedly assist, particularly when maintaining the duct system in your home or commercial building.

1. Flexible Ductwork

If you’re short on space, your home most likely has a flexible air duct. Flexible ductwork is usually in the shape of a cube, with no elbows or offsets.

This type of ductwork is created of a metal wire coil with a flexible plastic layer on top. Glass wool is used as thermal insulation in the adjustable air duct, but other materials such as polyethylene or metallized PET are also used.

2. Rigid Ductwork

They can be conical or rectangular and come in a variety of materials and sizes. They are frequently insulated as well. These are tough, long-lasting, and dependable. The following are the most common rigid ductwork types:

i) Sheet Metal Ducts

These ducts are similar to those seen in movies. The most commonly used materials for sheet metal ducts are galvanized steel and aluminum. Aluminum is a lightweight material that is simple to install. They also have the lowest risk of harboring dangerous molds or overgrowth.

ii) Fiberglass-Lined Ducts

These really are sheet metal ducts with an internal or external fibreglass lining, similar to those described above. The audio of the air – conditioning unit is muffled by this type of duct, which is common in retail and office buildings. However, the fibreglass in such ducts can deteriorate and finally release fibreglass particles in air, posing a serious health risk, particularly when exposed for an extended period of time. As a result, cleaning fibreglass-lined ducts is difficult: cleaning can harm the lining and discharge fibres. Mold and bacteria can grow in these ducts, causing them to become contaminated.

iii) Fiberboard Ducts

Fiberboard is created from fibreglass layers that were condensed and bonded with a resin, then protected from moisture with a foil laminate sheet. Because it is well insulated, this type of duct is appropriate for air conditioning units. Ventilation, like fibreglass-lined ducts, is not advice because it can become a breeding place for mold and mildew in humid areas. The roughness of the surface can also affect the flow of air and efficiency.

3. Semi-rigid Ducts

Semi-rigid ducting is term as the highest form of ventilation ducting available, as it provides installers with some advantages. As it is a zero leakage ventilation system, high-quality semi-rigid ductwork helps a ventilator perform at its best. Many semi-rigid duct processes have anti-bacterial and anti-static linings, making them easier to maintain.

High-quality semi-rigid duct systems, on the other hand, have a high crushability level. You should purchase good quality air ducts. Furthermore, some semi-rigid ducting processes provide the installer with flexibility by allowing them to switch between round and oval ductwork without sacrificing hydraulic pressure or performance levels.

Which One Is The Most Effective?

Though there are various types of ductwork currently available, sheet metal is the most recommended because it is non-porous and does not allow mold or bacteria to grow in the air ducts. Sheet metal ductwork can also help you avoid the health risks associated with fiberglass air ducts. To keep your indoor environmental quality in good condition, remember to clean your duct system on a regular basis; if you’re not sure when to do so, check out our post on how often air ducts should be scrubbed to learn more.

An adaptable air duct is an option if you have limited space in your home. This system air duct will save you room and allow you to move it around freely.

Conclusion

When replacing a heating unit in a building or home, it’s critical to consider the duct system. Ductwork is necessary because it is responsible for air distribution throughout the home or office. However this function has a direct effect on the central unit’s performance. You can make sure that your HVAC system functions correctly as a whole because you start replacing your ductwork at the same time as your central unit.

FAQs

Q. Which ductwork is the most effective?

Sheet metal ductwork is the most durable and least adequate to harbor mold or biological expansion due to its non-porous surface.

Q. What type of ductwork is the most efficient?

In terms of material use, airflow resistance, and air leakage, the round duct is the more efficient shape.

The disadvantage is that the round duct may not always fit in the available space. In these cases, the duct is rectangular or flat-oval to fit into the open space.

Q. Is it true that metal ducts are superior to flex ducts?

Existing trunk-and-branch heating systems benefit from flex ducts. This is due to their greater adaptability and versatility. Given the nature of steel, metal ducts are more rigid, making them ideal for constructing an entire HVAC system.
