When it comes to buildings with limited space, rectangular air ducts are the ideal choice. Unlike round ducts, which have a uniform diameter, rectangular ducts have two different measurements for width and height, allowing HVAC contractors to adjust the duct until it fits the wall. This is a major advantage over circular ducts, as they require a lower pressure drop than rectangular ducts. Circular ducts are also stiffer than rectangular ones, reducing the drum effect caused by the vibration of the duct. However, if not properly supported, rectangular ducts can produce excessive noise levels.
Additionally, they provide a better connection between the fan coil and the main duct than round ducts, as they come in longer lengths and require fewer expensive joints in the field and less sealing.
Flexibility
: Circular ducts can be adjusted in place more easily than rectangular ones, which usually require specific tools for modification. As round spiral ducts have fewer longitudinal and transverse joints in long straight sections of the duct, they tend to have fewer leaks than rectangular ducts.Duct Wall Thickness
: Rectangular air ducts usually require a thicker gauge of material to achieve stability comparable to that of a circular duct. In many ways, round metal ducts are cheaper than rectangular metal ducts as a means of transporting air. The spiral duct, also referred to as a round duct, is often made of galvanized steel and sometimes aluminum. As an expert in HVAC systems, I can confidently say that when it comes to buildings with limited space, rectangular air ducts are the best option.They provide better connection between the fan coil and the main duct than round ducts and require a lower pressure drop. However, circular ducts are more flexible and tend to have fewer leaks than rectangular ones. Additionally, round metal ducts are usually cheaper than rectangular metal ones. Rectangular air ducts offer several advantages over circular ones when it comes to limited space buildings. Furthermore, they are more adjustable and require less sealing than circular ones.
On the other hand, circular air ducts are more flexible and tend to have fewer leaks than rectangular ones. Additionally, round metal ducts are usually cheaper than rectangular metal ones. In conclusion, when it comes to buildings with limited space, rectangular air ducts are the best option for HVAC contractors. However, circular air ducts are more flexible and tend to have fewer leaks than rectangular ones. Additionally, round metal ducts are usually cheaper than rectangular metal ones.
