DW/172 – Canopy Airflow Calculation Application A technical support tool for mechanical engineers and commercial kitchen manufacturers. This mobile application has been developed to enable fast, accurate, and practical exhaust airflow calculations for kitchen canopies in compliance with the DW/172 standard in commercial kitchen projects. Completely free of charge, this tool is offered without commercial intent, aiming to contribute to the technical community and strengthen our company’s corporate image in the sector. Application Features: Exhaust airflow calculation according to the DW/172 standard Equipment heat load classification: Light, Medium, Heavy, Extra Heavy Duty Suitable airflow output for different canopy types Unit selection: m³/h or L/s Data saving and sharing functionality Simple, engineer-focused interface The application can be used by mechanical engineers, design offices, HVAC designers, kitchen consultants, and especially commercial kitchen manufacturers as a reliable reference tool both on-site and in the office. DW/172 Standard Technical Overview DW/172 is a standard published by the UK-based BESA (Building Engineering Services Association) containing technical guidelines for the design and operation of ventilation systems in commercial kitchens. DW/172 specifically focuses on calculating exhaust airflows based on the heat loads of cooking equipment used in kitchens. The standard covers: Airflow requirements according to types of cooking equipment Heat load classifications (light, medium, heavy, extra-heavy duty) Airflow variations based on canopy type and layout Recommended parameters for exhaust/fresh air ratios Load intensity differences according to kitchen operation type (fast food, fine dining, etc.) DW/172 is widely used in mechanical engineering projects and commercial kitchen manufacturing as a practical and applicable reference for airflow calculations.
