HVAC Efficiency and Performance Insights

Thermal dispersion airflow measurement devices continuously monitor airflow, providing performance insight and HVAC efficiency. By analyzing airflow data, you can identify energy savings opportunities and maintenance needs, provide fault detection and diagnostics (FDD), and make informed ongoing commissioning decisions (OCx). Monitoring helps to improve the operation and management for fine-tuned control, FDD, and maintenance needs.

Ensures Indoor Air Quality

After the code enforcement authorities have granted a building occupancy certification, there is no IAQ police to monitor indoor air quality. However, the IMC, UMC, and Title 24 codes mandate the design and commissioning of outdoor airflow rates. Monitoring and documenting these flow rates not only helps minimize the liability of the engineer and the owner for indoor air quality but also optimizes energy consumption. By monitoring and controlling the airflow in an HVAC system, you can ensure that it operates efficiently and effectively, allowing you to identify and address any potential issues. Fluctuations in fan speed or malfunctioning dampers can lead to imbalanced air distribution, resulting in inadequate conditioning in some areas while others experience over-conditioning. External factors such as wind and stack pressure can exacerbate these problems. Monitoring also applies to recirculating air handling and dedicated outdoor air systems and can detect more than 50% discrepancies in outdoor air ventilation rates from the desired setpoint. An audible alarm will sound when airflow falls below the designated set point. By monitoring airflow, you can identify these discrepancies early and take corrective action to prevent energy wastage and discomfort for occupants.

Reliable Accurate Airflow

Airflow monitoring is crucial for optimizing HVAC systems in buildings. By analyzing airflow rates over time, you can adjust system settings like fan speed and damper positions to improve energy efficiency and reduce operational costs. 

EBTRON’s thermal dispersion airflow measurement solution provides accurate and repeatable measurement in ducts and plenums. The rugged RH sensor, onboard barometric pressure sensor, and velocity-weighted temperature result in accurate relative humidity, enthalpy, and dew point calculations. It is ideal for supply, return, and outdoor air intake applications on systems with an airside economizer. Bluetooth® low-energy technology interface.

The device supports BACnet and Modbus communication protocols, which provide gradual trending data to the cloud for more in-depth analysis. This data can help make operational decisions for IAQ, energy efficiency, and maintenance. Only EBTRON provides this dual capability.

The EB-Link App lets you easily view airflow measurement data, including temperature, humidity, enthalpy, dewpoint, and other parameters for all EBTRON Gold Series products. The app also allows real-time and traverse data to be stored on your phone and emailed as a text file. This tool enhances TAB and commissioning or provides quick validation anytime without going through the BAS. With its exceptional product features, connectivity options, and alarm capability, EBTRON is the best choice for high-performance buildings.
