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.
