AIR BALANCING
Using appropriate instrumentation devices, air flow is measured and adjusted according to engineering specifications. Air balancing is important as it distributes air evenly across spaces, maximizing both comfort and efficiency.
HYDRONIC TESTING & BALANCING
Measuring and adjusting the flow rate to meet design criteria can also verify the correct function of associated pumps. This is important to ensure that equipment receives enough flow to function properly. Such equipment includes heat pumps, fan coil units, radiant heating, chilled beams, and heating and cooling coils.
AIR CHANGES TESTING
Testing air changes in various spaces ensures adequate ventilation by measuring how many times the air in a given space is completely replaced with clean air. The air change rate can be cross-referenced with recommended standards. A higher air change rate helps dilute air pollutants and improves indoor air quality.
Fume Hood Testing
Testing and balancing fume hoods in laboratory spaces ensure adequate ventilation and face velocity. Proper functioning of fume hoods is essential for the safety of technicians and the performance of the laboratory. Proper balancing of these systems will ensure that the fume hood alarm does not engage, preventing unnecessary downtime.
Ultrasonic Flow Reading
Using a flow meter to determine the flow rate of a liquid through a pipe is useful when circuit balancing valves or other flow measuring devices are not available. This allows for measuring the flow rate through the pipe to ensure that the related hydronic systems are functioning properly.
Sound Testing
Using a meter to measure acoustics at various bandwidths determines the noise criteria. This data can then be cross-referenced with the recommended standards for the tested spaces. If necessary, adjustments can be made to reduce noise in areas of concern.
Air & Hydronic Audits
Testing all air and water flows in a building is essential for checking proper functionality. An audit provides valuable insight into the overall performance of the system and can identify potential problem areas with low flow. It can pinpoint the location of blockages, such as a closed fire damper, balancing damper, seized actuator, or dirty strainer.
Sheave Changes
Changing motor and fan pulleys, as well as belts, can increase or reduce supply or exhaust air. This approach is practical in situations where airflow needs to be adjusted without the costly replacement of the supply or exhaust fan. It can also be useful for reducing noise levels.
CO / CO2 Testing
Engaging CO or CO2 sensors to ensure proper functionality of associated exhaust fans involves safely replicating a real scenario of unsafe carbon dioxide or carbon monoxide levels. This tests the sensors’ ability to engage an alarm and activate the interlocked exhaust fan.
Duct Leakage Testing
Duct leakage testing is an important diagnostic tool used to measure the efficacy of the installed ductwork. Leakage in the ducts can reduce the efficiency of the designed system. Therefore, it is worthwhile to assess leakage within ductwork systems and seal accordingly.
HVAC System Mapping
As renovations occur over time, the HVAC layout of the building changes. Recreating the layout is useful for building managers and operators. It is also more organized to have complete sets of the entire HVAC system for maintenance purposes. We can map out and create professional AutoCAD and PDF drawings. These drawings of the actual on-site HVAC layout are color-coordinated and labeled for convenience.
