The Science of ComfortTM
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?

Sound-power and sound-pressure levels are used to catalog acoustical performance for terminal units. The sound performance of a terminal unit is crucial when considering the comfort of occupants within a space. For example, some places have an open-ceiling design and are well suited to quiet units to minimize distracting noises.

When SolutionAir launched the RegenCore alternating mass-exchanger energy-recovery unit in 2019, the unit rocked the industry, delivering up to 92% effectiveness and no preheat requirement down to outdoor temperatures of −40°C/F. Its energy-recovery cores and four-damper design maximized energy conservation and minimized leakage, but combining the components meant RegenCore needed to be either mounted on a roof or concrete pad outdoors or installed in large mechanical rooms indoors.

The patent-pending Ceiling Air Purifier (CAP) by Price is the perfect combination of performance, aesthetics and efficiency. Simply replacing a 2-by-2-foot ceiling tile, the CAP is a stand-alone unit that can easily be integrated into a space – without any modifications to the existing HVAC system – and is independent of all building controls. Multiple diffuser faces are available to seamlessly fit in with the design intent of the surrounding area. The unit is discreetly contained above the ceiling for quiet operation at any of the three adjustable motor speeds.

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.
