EN 13779 Air Handling Unit Airflow Verification
The European Standard EN 13779 specifies the methodology for verifying the airflow of air handling units (AHUs). This standard is crucial for ensuring that AHUs operate efficiently and meet their designed performance levels. The testing procedure covers a range of parameters, including static pressure, fan speed, and system efficiency. Proper verification ensures that HVAC systems function as intended, leading to improved indoor air quality and energy savings.
During EN 13779 compliance testing, the following steps are typically taken:
- Sampling: Select a representative sample of AHUs from the production batch or installed units.
- Instrumentation Setup: Equip the AHU with appropriate flow measurement instruments such as anemometers and pitot tubes. Ensure that all test setups comply with EN 13779 requirements.
- Data Collection: Measure airflow, static pressure, fan speed, and other relevant parameters under different operating conditions. This helps in assessing the actual performance of the AHU against its design specifications.
- Compliance Check: Compare measured data with the design values as per EN 13779. Calculate system efficiency to verify adherence to the standard.
- Reporting: Generate a detailed report summarizing all test results, including any deviations from specified limits.
The importance of this service extends beyond mere compliance; it ensures that HVAC systems contribute effectively to energy conservation and occupant comfort. By adhering strictly to EN 13779 guidelines, laboratories like Eurolab can provide accurate and reliable verification results, which are essential for maintaining the integrity of HVAC equipment.
Table 1: Common Parameters Measured During EN 13779 Testing
| Parameter | Description |
|---|---|
| Static Pressure | Difference in pressure between the supply and return air ducts. |
| Airflow Rate | Volume of air passing through the AHU per unit time. |
| Fan Speed | The rotational speed of the fan motor. |
| System Efficiency | The ratio of output power to input power, indicating how efficiently energy is used. |
Table 2: Acceptance Criteria According to EN 13779
| Parameter | Critical Limits |
|---|---|
| Static Pressure Deviation | No more than ±5% from the design value. |
| Airflow Rate Variance | No more than ±10% from the design value. |
| Fan Speed Tolerance | Within ±2% of the nominal speed. |
| System Efficiency Range | Within ±5% of the expected efficiency level. |
In summary, EN 13779 testing is a critical process that ensures HVAC systems meet their design parameters and operate efficiently. This service plays an essential role in maintaining indoor air quality, reducing energy consumption, and complying with international standards.
