IEC 61591 Range Hood Test System for Airflow Performance Measurement

IEC 61591 Range Hood Test System for Cooking Fume Extractor Performance Testing

Kitchen ventilation appliances such as range hoods must meet strict airflow performance and efficiency requirements to ensure effective removal of cooking fumes and smoke. The IEC 61591 range hood test system is designed to evaluate the aerodynamic and electrical performance of cooking fume extractors under standardized laboratory conditions.

The testing system measures key performance indicators including airflow rate, static pressure, electrical power consumption, rotational speed, temperature, and humidity. These parameters are essential for determining whether a range hood meets the performance limits defined by international appliance standards such as IEC 61591, AMCA 210, and ISO 5801.

The airflow measurement process uses a calibrated nozzle airflow method combined with differential pressure sensing. By measuring the pressure difference across standard nozzles, the system calculates the airflow generated by the tested appliance. This method ensures reliable airflow measurement across the full testing range.

A frequency-controlled auxiliary fan provides stable airflow conditions and allows engineers to adjust airflow continuously during the testing process. The airflow chamber contains flow equalizing plates and nozzle components that ensure consistent airflow distribution and accurate measurement results.

The system is controlled by an industrial computer interface that allows operators to monitor real-time test data and automatically collect measurement results. The software records airflow, pressure, electrical parameters, and environmental data while generating performance curves such as airflow versus static pressure and efficiency curves.

With automated testing functions and accurate sensor integration, the IEC 61591 range hood test system provides reliable performance evaluation for product development, certification testing, and quality control applications.
