EN 14879 Air Terminal Unit Performance Testing
The EN 14879 standard governs the performance of air terminal units (ATUs) used in HVAC systems. These ATUs play a crucial role in ensuring that buildings are adequately protected from lightning strikes, which can cause significant damage to electrical and electronic equipment. The testing process outlined by this standard is essential for quality managers, compliance officers, R&D engineers, and procurement personnel involved in HVAC system design and installation.
The tests conducted under EN 14879 aim to evaluate the ATU's ability to withstand lightning strikes without failing or causing damage. This involves simulating a real-world scenario where an air terminal unit is subjected to high-voltage surges, ensuring it meets the required performance criteria specified in the standard.
The testing process typically begins with thorough preparation of the ATUs. Engineers ensure that each specimen undergoes stringent quality checks before being placed under test conditions. The specimens are then connected to a lightning simulator capable of generating controlled high-voltage surges, simulating the effects of actual lightning strikes. This setup allows for precise control over variables such as voltage amplitude and duration.
The testing process involves multiple stages designed to assess different aspects of ATU performance:
- Static discharge resistance
- Dynamic discharge resistance
- Withstand capability against high-voltage surges
- Protection level (PL) classification according to IEC 62305-1
Each stage involves rigorous measurements and observations. Engineers record data such as surge current, voltage waveform, and energy absorbed by the ATU during testing. These metrics are crucial for determining whether the unit meets the stringent requirements set forth in EN 14879.
The results of these tests are documented meticulously. Compliance officers rely on these reports to verify that all ATUs meet regulatory standards and can be safely installed in commercial and residential buildings. R&D engineers use this data to refine future designs, enhancing the performance and reliability of air terminal units.
