Ventilation & AHU Commissioning & Balancing
Ventilation System Commissioning, Balancing, Testing & Servicing
Correctly designed ventilation systems must be commissioned and balanced to ensure that the required air changes and airflow rates are achieved throughout the building or process environment.
RB Industrial provides commissioning, balancing, testing and servicing of general ventilation systems and Air Handling Units (AHUs), including complex multi-branch systems and systems incorporating Building Management Systems, variable air volume control and pressure feedback.
Initial System Commissioning
Initial commissioning can include:
- System balancing
- Confirmation of correct air changes
- Confirmation of airflow against specification
- Fan performance
- Supply and extract airflow
- System operation
- Control system configuration
- Design and test data
- Operation and maintenance manuals
- System logbooks
The objective is to confirm that the installed system performs in accordance with its design requirements.
Complex Ventilation System Balancing
RB Industrial has experience in balancing multi-branch and complex ventilation systems.
Balancing ensures that airflow is distributed correctly between branches and that the system achieves the required performance at the relevant points.
Where systems have been modified, extended or reconfigured, balancing can also identify changes in system resistance and airflow distribution.
BMS Setup & Commissioning
We can assist with Building Management System (BMS) setup and commissioning, including systems such as TREND BMS.
This can include configuration and commissioning of:
- Pressure control
- Airflow control
- Temperature
- Humidity
- Fan speed
- VAV systems
- CAV systems
- Pressure feedback
- Transmitters
- Control loops
Fan Speed Inverters & Pressure Feedback
Commissioning of fan speed inverters can include:
- Inverter configuration
- Fan speed setup
- Pressure feedback
- Constant Volume Damper (CVD) systems
- Variable Air Volume (VAV) systems
- Supply and extract control
- Pressure/flow transmitter configuration
- Proportional/integral control tuning
Correct control tuning helps ensure the system responds effectively to changing demand while maintaining the required ventilation performance.
Energy-Efficient Ventilation Control
Ventilation can be controlled according to occupancy and demand where the system design permits.
For example, PIR sensors or light-switch signals can be used to control room ventilation.
Individual rooms can incorporate constant volume dampers on supply and extract systems, allowing the ventilation system to maintain the required airflow while individual room ventilation is switched on or off.
Correctly configured variable-speed and pressure-feedback systems can also help reduce unnecessary fan energy consumption.
Temperature & Humidity Control
Our commissioning services can also include setup and control tuning for:
- Temperature control
- Humidity control
- Sensors
- Transmitters
- Control loops
- Proportional/integral control
Duct Leakage Testing
RB Industrial can carry out duct leakage testing to DW/143.
Testing can include:
- Class A zones
- Class B zones
- Class C zones
- Calculation of duct surface area
- Confirmation of permitted leakage allowance
- Blanking of grilles
- Appropriate zoning of the duct system
- Pressure testing
- Recording of test results
Duct leakage can have a significant effect on the performance of ventilation and extraction systems, particularly where systems are required to deliver specific airflow rates.
Commissioning Documentation & Logbooks
Following commissioning and balancing, we can provide clear documentation including:
- Test data
- Design information
- Airflow measurements
- Balancing results
- System diagrams
- Operating information
- Maintenance recommendations
- Modification recommendations
- System logbook information
This provides a useful reference for future maintenance, testing and system modifications.
Fire Damper Testing
Where applicable, ventilation system testing and servicing can also include assessment and testing of fire damper arrangements and associated release mechanisms.
Any defects or maintenance requirements identified can be recorded within the system report.
