Four Approaches for a Quieter System
There is a misconception that VAV diffusers are noisy, but a review of their performance data shows that they have a pressure versus noise relationship similar to that of all diffusers. The difference is that VAV diffusers have a built-in VAV damper and can close to a minimum, possibly building up pressure in the system. It is the higher pressure that makes diffusers noisy, and because of this, a method of pressure control should be used in every VAV diffuser system.

A Look at Air Distribution and Patient Safety Standards
Patient care is constantly evolving, and these changes impact how we design spaces within psychiatric care facilities – including the components for air distribution systems. Patient health and safety is at the forefront of design considerations, but a challenge faced by many HVAC designers is a lack of guidance as to what types of air inlets and outlets should be installed in these unique spaces.

Understanding Volumetric Offset and Direct Pressure Control
Maintaining a pressure relationship between a target and reference space provides control over the direction of air leakage that occurs between the spaces. Controlling the direction of this “transfer air” helps to prevent the migration of unwanted particles, which can directly impact occupants and products in or near such spaces.

Price Noise Control Team Delivers Custom Enclosure for Minneapolis School
Public schools play an important role in the communities they serve. More than just a place for students to learn, schools offer valuable extracurricular programs for young people and their families. They help foster a connection between the students and the world around them, and the best schools continually rise to the needs of their neighbors. That was the case in Minneapolis, MN, when Ella Baker Global Studies and Humanities Magnet School (formerly Jefferson Middle School) realized its HVAC system was causing too much noise.
