Understanding and Designing Chilled-Beam Systems

Share This

Course Length: 3 hours

This course is primarily designed for mechanical engineers with at least three years of experience in the design of commercial HVAC systems. Chilled-beam systems save on cooling and transport energy by decoupling most or all of the space sensible loads from the air-distribution system and removing them with water, a much more efficient heat transfer medium.

Attendees will review HVAC fundamentals as they relate to chilled-beam system design. Attendees will understand the system benefit, be able to identify suitable applications, and design chilled-beam systems to optimize the energy and operational benefits. Properly identifying and controlling equipment and components that optimize design are also major components of this course. Efficient design of a chilled-beam system requires some departure from practices and conventions used to design all-air VAV systems.

As most North American HVAC designers have almost exclusively used VAV systems, they are often not aware of the energy benefits that can be derived by departure from some of these VAV-system rule-of thumb design procedures.  This course seeks to identify those areas where slight design modifications can greatly enhance the performance of the system. This course is intended to educate the attendees so that they can decide whether claims regarding the operation and costs of chilled-beam systems are justified.

This ALI course/seminar may be a suitable resource to help prepare for a Certification exam or earn PDHs for recertification.
