Cole Krisko 

Degree qualified Mechanical Engineer from the University of Manitoba, Canada. 

Five years of service in HVAC and connected industries, including Antec Controls, MacDon Industries, and Holyoake by Price Australia.  

Past two years at Holyoake by Price as a lead technical specialist for the Critical Environments team. Primarily focused on supporting projects in the design and selection of air diffusion and airflow control equipment. Project types include laboratories, operating theatres, and clean rooms. 

 

Diffuser Selection Might Be More Critical Than You Think! 

 

Selecting the correct diffuser is essential in critical environments where air quality and containment control are paramount. The function of diffusers in these settings extends beyond simple air distribution; they play an integral role in maintaining cleanliness standards, ensuring particulate and microbial contamination are minimized. The appropriate diffuser not only effectively manages airflow to prevent the accumulation of contaminants but also contributes to the comfort and safety of personnel working within these environments. 

 

In critical spaces, the distribution, velocity, and direction of airflow are essential factors that influence the room’s particulate levels. The type of diffuser impacts these variables, affecting how airborne particles are managed. For example, laminar flow diffusers supply air in a unidirectional pattern with minimal turbulence, reducing the risk of cross-contamination in sensitive areas. In contrast, swirl diffusers are design to effectively mix and entrain air which may be suitable for less critical spaces but can disturb particulates settled on surfaces. 

 

Furthermore, air change rates, pressurization and room leakage rates determine the required supply and exhaust airflow for a critical space. Airflow is a key element of diffuser selection as it determines the pressure drop, throw pattern, and noise. Additionally, diffuser layout has a significant effect on thermal comfort and occupant safety. In conclusion, appropriate diffuser selection is imperative in optimizing the operational performance and environmental safety of critical spaces.
