The process of testing and balancing the heating, ventilating, and air-conditioning (HVAC system) and related control systems to perform at the design intent and operate at an optimum level.
To ensure hydronic systems are properly adjusted with cross checks, such as pump curves, pressure drop across components, and flow measuring devices.
Duct leakage reduces the air quantity at the system terminals and should be minimized. Excessive leakage will lead to increased fan speeds to compensate for the reduced terminal airflow, and, therefore, increase energy use to overcome the leakage.
Many devices are factory tested under ideal conditions for sound, which may be totally different than the actual installed conditions. Often the TAB agency is requested to help identify sound problems or take measurements.
Inspection and testing of HVAC equipment to aid in identifying problem areas. Also, to determine current or required capacity of equipment operating conditions.
Controlling the spread of airborne infectious disease in health care facilities is a serious concern. To minimize the spread of disease, it is important that certain rooms have proper flow and pressure to contain these infectious hazards.
Operating rooms are tested for proper airflow, air changes, and pressures per the required health care standard.
Each exhaust device in the laboratory should be set between 100% and 110% of design airflow. All fume hoods, bio-safety cabinets, canopy hoods, and snorkels should be traversed to establish airflow.
Hoods are used for removal grease and smoke. Hoods are required over kitchen equipment that produce smoke or grease laden vapors.
Calculating pulley and belt sizes for HVAC equipment that needs adjusted to meet design criteria.
