Essential Strategies for Cleanroom Design

Cleanrooms are a growing market worldwide within the HVAC industry. Cleanrooms are specialized spaces where the control of airborne particles is critical to the processes occurring there. Great care must be taken to avoid the introduction and generation of particles as well as to remove existing particles as quickly as possible.

Taking a Closer Look at Air Distribution in Critical Environments

Creating high-performing, well-ventilated spaces is essential in critical environments such as hospital operating rooms, patient rooms and other medical spaces. Indoor air quality directly affects occupants’ well-being and productivity and, in the case of pharmaceutical compounding, for instance, can have a profound impact on processes that occur in the space.

Price Ultrasuite Combines HVAC and LED Lighting in One Revolutionary System

Integrated operating room ceiling systems consolidate multiple services in a single system to streamline supply, installation and on-site coordination. Price Industries’ Ultrasuite^® system (pat. 10,401,049) combines hospital-grade LED lighting with precision-equalized laminar airflow diffusers to eliminate the traditional “light ring” and open valuable ceiling space for surgical equipment – all while mitigating contamination in the surgical zone.

An Overview of Air Distribution and Filtration Requirements

The main goal of operating room air distribution design is to maintain a hygienic surgical zone around the patient and surgical team. Patient well-being is critical, and a well-designed air distribution system can help mitigate surgical site infections.

Examining the Science of Laminar Flow and How It’s Used in HVAC Applications

Laminar flow is a type of fluid motion characterized by smooth parallel layers, or laminae, that can slide relative to each other with little to no mixing. This is in contrast to turbulent flows, where chaotic changes in pressure and velocity can be observed as vortices, or eddies (reverse swirling currents), and where much more mixing occurs within the fluid.
