Can Chilled Beams Be Used in Heating?

Posted by Price Industries on May 16, 2023 at 9:00 AM

Working with Active and Passive Beams in Cold Climates

For applications in climates that require a significant amount of heating, owners, engineers and contractors often wonder if chilled beams are an appropriate choice for their projects. Since the “chilled” part of the chilled beam name only specifies cooling, can you also produce heat with a chilled beam?

Can Chilled Beams Be Used in Open Ceilings?

Posted by Price Industries on February 21, 2023 at 9:00 AM

Active Chilled Beams and the Coanda Effect

Open-ceiling spaces are becoming increasingly popular, especially in the architectural industry. Aside from providing a feeling of spaciousness and a contemporary aesthetic, the absence of a ceiling grid or drywall also simplifies coordination and allows for more flexibility with ceiling fixtures. But can chilled beams be used in these open-ceiling spaces? As is the case with other air diffuser products, the answer is yes – but with one simple addition.

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?

What Is an Active Chilled Beam Cabinet?

Combining the Benefits of Chilled Beams and Displacement Ventilation

Chilled beam systems use the heat transfer capabilities of water to provide sensible cooling to a space. As we’ve discussed previously on the blog, when the system is in cooling mode, the induction process facilitated by the chilled beam nozzles causes warmer room air to mix with the colder primary air, providing the space with supply air with temperatures at 62°F to 66°F – much warmer than the 55°F supply air provided by conventional cooling systems.

What Is a Passive Chilled Beam?

Posted by Price Industries on May 10, 2022 at 9:29 AM

Using Natural Convection to Provide Energy-Efficient Comfort

Chilled beam technology is often separated into two categories: active and passive. As we explored in a previous blog post, active chilled beams take in primary air from an air handler, which is then pressurized and released through a series of nozzles. Passive chilled beams, however, do not have any supply air ducted to them and operate utilizing natural convection. This energy-efficient cooling device is often coupled with other air systems such as underfloor air, displacement ventilation and active chilled beams.
