Range Hood Air Volume Testing System for IEC 61591 Air Performance Testing

Range Hood Air Volume Testing System – IEC 61591 Air Performance & Efficiency Evaluation

The Range Hood Air Volume Testing System is a fully automated, high-precision test platform engineered by KingPo to evaluate the aerodynamic performance of range hoods and cooking fume extractors in strict accordance with IEC 61591:2014 (household range hoods – methods for measuring performance) and GB/T 17713-2022. The system adopts a blowing test configuration featuring a standardized air chamber (600×600 mm interface), multiple nozzles (8 pieces, φ15 to φ60), flow equalizing orifice plate, and a frequency-controlled auxiliary diagonal flow fan to achieve precise regulation and measurement of air volume and static pressure.

It enables accurate determination of maximum static pressure (zero air volume), maximum air volume (zero static pressure), working air volume point, full pressure efficiency, fluid dynamic efficiency, energy efficiency index, and characteristic curves (P-Q, air volume-speed/power/efficiency). The system supports both inhalation and discharge modes, with fully automatic and manual test options, making it an essential tool for R&D, type approval, and production quality verification of range hoods, ventilation fans, and similar appliances.

Professional Construction & Technical Precision

Key features include:

• Air Chamber: Cross-section ≤1700×500×500 mm, equipped with 8 nozzles (manual plug operation), transparent access door, flow equalizing orifice plate
• Auxiliary Fan: Diagonal flow type, maximum 25 m³/min at 1000 Pa, stepless frequency control via converter
• Damper Control: Electrically adjustable damper with variable speed motor (forward/reverse, high/low speed) for precise airflow regulation
• Measurement Accuracy: Static pressure 0–1500 Pa (±1% or ±1.5 Pa), electrical parameters 0.2 level accuracy
• Control System: PLC + large-screen computer, automatic nozzle selection, curve plotting (P-Q, efficiency, power), report generation
• Test Modes: Fully automatic (based on maximum air volume point or specified pressure/volume points) and manual (air volume/static pressure/frequency-based)

These elements ensure high repeatability, compliance, and operational efficiency in range hood air performance testing.

Primary Use Cases & Business Value

The range hood air volume testing system supports critical stages:

• Product Development – Optimize impeller design, motor efficiency, and duct resistance for improved performance
• Certification Testing – Generate traceable data for IEC 61591, GB/T 17713 compliance and energy labeling
• Quality Control – Batch verification of maximum/working air volume and static pressure
• Performance Analysis – Compare inhalation vs. discharge modes under various operating conditions

It accelerates design iteration, shortens certification timelines, and strengthens product competitiveness.
