The application can be used as a reliable reference tool in the field or in the office for mechanical engineers, project offices, HVAC designers, kitchen consultants, and especially industrial kitchen manufacturers.

DW/172 Standard Technical Description

DW/172 is a standard published by the UK-based BESA (Building Engineering Services Association) that contains technical rules for the design and operation of ventilation systems in commercial kitchens. DW/172 is based on the calculation of exhaust airflow rates based on the thermal loads of cooking equipment used in kitchens.

The Standard Scope:

Airflow requirements by cooking equipment type
Thermal load classifications (light, medium, heavy, extra-heavy duty)
Flow rate differences by hood type and placement
Recommended parameters for exhaust/fresh air ratios
Load density differences by kitchen operation type (fast food, fine dining, etc.)
DW/172 is a widely used, practical, and applicable resource for airflow calculations, particularly in mechanical engineering projects and industrial kitchen production.
