The TAB Process
The testing, adjusting, and balancing (TAB) process is a critical step in ensuring optimal performance and efficiency of HVAC systems in buildings. TAB involves a series of tests and adjustments to ensure that the HVAC system is delivering the right amount of heating and cooling to each area of the building and maintaining the desired indoor air quality. Here is an overview of the different stages of the TAB process:
Testing : The first stage of the TAB process involves conducting tests to identify any inefficiencies or malfunctions in the HVAC system. Tests may include measuring airflow, temperature, humidity, and pressure in different areas of the building.
Adjusting : Once inefficiencies or malfunctions have been identified through testing, the next stage is adjusting the HVAC system to address these issues. Adjustments may include modifying airflow, adjusting temperature and humidity levels, and making changes to the HVAC system’s components, such as dampers, valves, and thermostats.
Balancing : The final stage of the TAB process is balancing the HVAC system to ensure that it is delivering the right amount of heating and cooling to each area of the building. Balancing involves adjusting the HVAC system’s components, such as dampers and valves, to ensure that air and water flow rates are balanced throughout the system.
