AHU FAT (Factory Acceptance Test)
AHU stands for Air Handling Unit, which is an essential component of an HVAC (Heating, Ventilation, and Air Conditioning) system. A factory acceptance test (FAT) is a crucial step in the manufacturing process of an AHU, where the AHU is tested and inspected to ensure that it meets the design specifications and customer requirements.
The FAT typically takes place at the AHU manufacturer's factory and involves various tests and inspections to verify that the AHU is functioning correctly and meets the required performance parameters. These tests may include:
1. Visual inspection: The AHU is inspected for any damage or defects.
2. Functional testing: The AHU is tested to ensure that all components and systems are functioning correctly, such as the fans, motors, dampers, filters, and sensors.
3. Airflow testing: The AHU is tested to ensure that it delivers the required airflow at the specified static pressure.
4. Noise testing: The AHU is tested to ensure that it meets the specified noise levels.
5. Electrical testing: The AHU is tested to ensure that all electrical components are functioning correctly.
6. Controls testing: The AHU's control system is tested to ensure that it can accurately control the AHU's operation.
Once the AHU has passed all the tests and inspections, a factory acceptance certificate is issued, indicating that the AHU meets the design specifications and customer requirements. This certificate is an essential document that confirms that the AHU has been thoroughly tested and inspected and is ready for shipment to the customer's site.
