Calculation of equivalent diameter of air ducts

Program that carries out comparison calculations of the diameters of quadrangular ducts with circular ones and vice versa. By entering the dimensions in mm of the sides of the quadrangular ducting, immediately find the diameter of the corresponding circular ducting. Vice versa, by entering the diameter of the circular duct, choosing the size of one side, finds the other side of the quadrangular duct.

Calculating the equivalent diameter of air ducts is an essential step in the design and management of air distribution systems in HVAC (Heating, Ventilation, and Air Conditioning) engineering. This parameter is fundamental to ensure that the air flow inside the channels is optimized in terms of energy efficiency, reduction of pressure drops and uniform distribution of the air.

The reason for this program

This program was designed and created by Itieffe with the aim of providing a complete guide on the calculation of the equivalent diameter of the air channels. We will explore fundamental concepts, calculation methodologies, practical tools and applications in the design and optimization of HVAC systems.

The calculation of the equivalent diameter is crucial for HVAC engineers, system designers and operators in the sector, as it allows determining the optimal dimensions of the air ducts, comparing the diameters of quadrangular ducts with circular ones and vice versa. This directly affects the system's ability to distribute air evenly, control pressure losses and maintain energy efficiency.

With this program, we will guide you through the calculation process, explaining theoretical concepts and offering practical examples. We will explore how to take into account the important variable such as the shape of the channels.

Itieffe is pleased to accompany you on this learning journey, which will equip you with the skills necessary to design and manage efficient and high-performance HVAC systems. Understanding this agenda is a critical step toward achieving the goal of air distribution systems that contribute to the comfort, energy efficiency and sustainability of built environments.

Calculation of equivalent diameter of air ducts

Program that performs comparative calculations of the diameters of the quadrangular ducts with the circular ones and vice versa.

By entering the dimensions in mm of the sides of the quadrangular duct, immediately find the diameter of the corresponding circular duct.

Conversely, by entering the diameter of the circular duct, choosing the size of one side, find the other side of the quadrangular ducting.

Let's take an example

In the section “Quadrangular channels”, by entering the base and the height of the channel, the equivalent and rounded diameter of the circular channel is obtained.

In the "Circular channels" section, by entering the diameter of the circular channel and by entering the dimensions of one side of the quadrangular one, the rounded dimensions of the other side are obtained
