Air ducts flow rate dimension speed
Chart for quick selection of dimensions, flow rates and air speed in the ducts. There is a clean printable version.
This document created by Itieffe represents a precious tool for engineers, designers and air conditioning and ventilation professionals. This graph provides a quick and intuitive overview of the relationships between duct sizes, air flow rates and flow speeds, making it easier to design and select air distribution systems.
In this introduction, we would like to highlight the importance of carefully designing air ducting systems to ensure comfort and efficiency in heating, ventilation and air conditioning (HVAC) systems. Choosing the appropriate dimensions of the ducts and correctly managing air flows and speeds are essential to guarantee a healthy and comfortable internal environment.
Key features and topics addressed in this chart include:
- Duct dimensions: The chart presents a range of commonly used duct sizes, including diameters and cross sections. This data is essential for the initial design and selection of ductwork materials.
- Air flow rates: information is provided on recommended air flow rates for each duct size. These flow rates are related to the volume of air needed for the HVAC system to maintain thermal comfort and air quality.
- Air speed: the graph illustrates the air speeds that can be obtained for the different dimensions of the ducts and air flow rates. Air speeds affect system efficiency and noise level.
- Energy efficiency: the importance of considering energy efficiency in the design of HVAC systems is discussed, trying to minimize pressure losses and heat losses.
The main objective of this graphic is to simplify the process of designing and selecting air duct systems, helping HVAC operators make informed decisions and ensure the comfort and efficiency of ventilation systems. Correct duct design is essential for the well-being of people indoors and for optimizing the energy costs associated with HVAC systems.
