Using Particle Tracking to Optimize Indoor Air Quality

During the COVID-19 pandemic, we’ve seen an increased focus on indoor air quality – especially regarding the spread of infectious diseases in all types of indoor environments. Since one path of transmission is through exhaled droplets both large and small, the engineering community is particularly interested in how those particles move in indoor environments.

Taking Flexibility with Chilled Beams to the Next Level

In a building’s life cycle, the interior infrastructure may undergo multiple renovations or tenant improvements (TI). A TI project will typically involve adding, moving, or removing walls, furniture,
occupants, electrical wiring, and even the HVAC air distribution system in some instances. TI projects for the air distribution system can cost up to $30/ft², which brings forth the challenge of ensuring flexibility in the HVAC design to minimize future TI or renovation costs.

Now You Can Go Inside for a Breath of Fresh Air

In today’s world, indoor air quality is an increasing concern and the ability to provide clean air to room occupants is more important than ever. Most commercial spaces focus primarily on cost and thermal comfort while air quality is based on minimum requirements, which can result in lower than optimal air quality.

The Room Air Purifier (RAP) is an ideal option for improving indoor air quality wherever and whenever you need it, particularly in high density areas like office spaces, classrooms, fitness centers, retail and restaurants. It is designed to continuously cycle air through a HEPA filter, eliminating unwanted dust particles, germs and contaminants.

VAV Diffusers in High Performance Air Systems

Posted by Price Industries on August 11, 2020 at 12:04 PM

Creating Comfort, Efficiency and Sustainability with VAV Diffusers

High performance air systems demand modern design approaches with leading-edge
products and technology in order to optimize comfort and reduce energy consumption. A
comfortable environment is achieved by providing the smallest possible zones of temperature
control, allowing for individual temperature distribution and better air movement. Reduction
in energy is realized by designing a low-pressure HVAC system that allows for maximum
turn-down while maintaining temperatures.
