An Airflow Capture Hood is a device used to measure and quantify the volume of air flowing through air supply or return vents in HVAC (Heating, Ventilation, and Air Conditioning) systems. It consists of a hood-shaped device with an integrated airflow sensor and a digital display or data logging capabilities.
The Airflow Capture Hood is placed over the air vent, and the airflow is captured and measured as it passes through the hood. The device provides readings of air velocity, air volume, temperature, and other relevant parameters, allowing HVAC professionals to assess the performance and balance of the system.
By using an Airflow Capture Hood, technicians can measure and verify the airflow rates at different registers, grilles, diffusers, or exhaust vents. This information is crucial for diagnosing issues such as inadequate or excessive airflow, identifying ductwork obstructions, and ensuring proper air distribution throughout the building.
The measurements obtained from the Airflow Capture Hood can be used to evaluate the effectiveness of HVAC system design, detect air distribution imbalances, optimise system performance, and verify compliance with design specifications and industry standards.
Airflow Capture Hoods are designed to be easy to use, portable, and accurate. They may feature a lightweight design, a digital display for instant readings, and an adjustable airflow capture area to accommodate various vent sizes. Some advanced models may offer wireless connectivity and data logging capabilities for more detailed analysis and reporting.
Using an Airflow Capture Hood helps ensure that HVAC systems operate efficiently, provide optimal indoor air quality and thermal comfort, and minimise energy consumption. Regular airflow measurements and adjustments based on the captured data contribute to the overall performance and efficiency of the HVAC system.
