Exploring the Inner Workings of Mechanical VAV Diffusers

In a previous blog post, we discussed variable air volume (VAV) diffusers and how these simple devices create small-zone comfort. VAV diffusers are available in two basic types: mechanical (thermal) and digital (electric). In this post, we take a closer look at the mechanical version, which requires no electrical or pneumatic connections and is powered by the temperature of the air.

More Space, More Capacity and a World-Class Paint Line

In the summer of 2021, Price’s Golspie North manufacturing facility in Winnipeg, MB, completed a massive expansion. Measuring 130,000 square feet (108,000 square feet of which is dedicated manufacturing space), the Golspie North project is the largest expansion to be completed on the Winnipeg campus. The additional space dramatically increased manufacturing and surge capacity for the Critical Environments product group and PARC, Price’s architectural ceilings business.

Controlling Unwanted Noise from the Source to the Receiver

An acoustic panel is one of many names that describe a modular component used to block or absorb noise where it’s unwanted. Also known as a double-walled panel, sandwich panel, insulated panel, thermal panel, double-walled ductwork or plenum wall, this engineered building element contains or reduces sound energy at different stages along the path that sound travels from the source to the receiver.

When You Should – and Shouldn’t – Use These Powerful Devices

Commonly used in both residential and commercial applications, a seven-day programmable thermostat is what sets the weekly schedule for the equipment it is controlling. We often see programmable thermostats connected to home furnaces, for instance; the device’s schedule is programmed for different days of the week to operate the fan within the furnace and any heating or cooling associated with it according to the homeowner’s needs.

Measures to Mitigate Condensation Concerns

More than ever before, engineers, contractors and building owners are choosing chilled beams for their projects. This energy-efficient technology uses the heat transfer capabilities of air and water to provide heating and cooling in a space. But the concept of installing a water coil within the housing of the chilled beam raises some very important questions: will there be condensation, and are drain pans required?
