HVAC Square Duct

HVAC square ducts are a type of air duct used in heating, ventilation, and air conditioning (HVAC) systems to distribute air throughout a building. Square ducts are typically made of galvanized steel or aluminium and come in various sizes to accommodate different airflow requirements.

Key points of HVAC Square Ducts:

Construction: Square ducts are fabricated by bending and joining flat metal sheets into a square or rectangular shape. The seams are typically sealed with adhesive or airtight fasteners to prevent air leakage.

Sizes: Square ducts come in different sizes to meet the specific needs of an HVAC system. Common sizes range from 4 inches by 4 inches (100 mm by 100 mm) to larger sizes like 48 inches by 48 inches (1,200 mm by 1,200 mm) or even larger for industrial applications.

Airflow Capacity: The size of the square duct directly affects the airflow capacity. Larger ducts allow for higher airflow rates, while smaller ducts restrict airflow and may cause pressure drop and decreased system performance.

Insulation: Square ducts can be insulated to reduce heat transfer and minimize energy loss. Insulation helps maintain the temperature of the air being distributed and reduces condensation on the duct surface.

Dampers: Dampers are often installed within square ducts to control airflow and balance the distribution of air in different zones or rooms. Dampers can be manually adjusted or automated, allowing for precise control over the air supply.

Duct Fittings: Various fittings such as elbows, transitions, and offsets are used to change the direction, shape, or size of the ductwork as needed to fit the layout of the building. These fittings help ensure proper airflow and efficient distribution.

Maintenance: Regular inspection and cleaning of square ducts are important to maintain optimal system performance and indoor air quality. Accumulated dust, debris, or microbial growth can hinder airflow and lead to potential health issues.

When designing an HVAC system, factors such as the required airflow, pressure drop, noise level, and space constraints should be considered to determine the appropriate size and configuration of square ducts. It's best to consult with a professional HVAC engineer or contractor to ensure the system is designed and installed correctly.
