This CPD presentation by Brooke Air Diffusion Ltd explores HVAC principles to improve indoor comfort and air quality. It covers:

• HVAC system components and functionality.
• Ventilation, air conditioning, and airflow control principles.
• Ductwork design and air distribution techniques.
• Selection criteria for grilles, diffusers and louvres.

The presentation includes case studies highlighting practical applications in residential, commercial, and industrial settings. Attendees will gain actionable insights into optimising HVAC systems for enhanced performance and well-being

Induction Ratios of Grilles and Diffusers

This CPD presentation by Brooke Air Diffusion Ltd examines how induction ratios in

HVAC grilles and diffusers influence air mixing, thermal comfort, and energy

performance. It covers:

• The principles of air jet behaviour and entrainment.
• Definition and calculation of induction ratio (IR).
• The impact of outlet type, placement, and velocity on mixing.
• Selection and commissioning guidance for different diffuser types.

The session includes technical comparisons and design strategies to support effective

diffuser specification across varied building applications. Attendees will gain a deeper

understanding of diffuser performance and its role in occupant comfort and HVAC

system efficiency.
