Chilled Beams and Pinnacle Application Guide

    Columbia, MO - August 24, 2009 - Due to the growing number of LEED certified and “Green” buildings being designed, the significant energy efficiency benefits offered by chilled beam technologies have caught the interest of a growing number of architects and engineers worldwide. Chilled beam systems can improve the quality of the indoor environment; increasing occupant comfort and reducing energy costs, while cutting the size of air handling units and the associated ducted airflow by 66% when compared to traditional HVAC designs.

    As a result of these benefits, chilled beam systems (both active and passive) have become the system design of choice in Scandinavia, central Europe and the United Kingdom over the past 20 years. High building efficiency standards, the need to cut carbon emissions and regulations limiting the fan energy that can be used based on building size have accelerated their use in these markets in recent years.

    Fläkt Woods has been a dominant chilled beam supplier and technology leader in the European market for more than 30 years. SEMCO, a Fläkt Woods company, is now producing this chilled beam technology in the US. Ambient humidity levels in the US are often much higher than those in Europe. High space humidity presents a challenge to applying chilled beams. SEMCO has invested in design tools and test facilities to understand and address this challenge.

    Chilled beams systems demand that internal latent loads be accurately estimated and that indoor humidity levels be controlled effectively to avoid the possibility of condensation on the “cooled” coil (active beam) mounted at the ceiling surfaces.

    In humid climates, this demands the primary airflow to be delivered at low dew points if the energy efficiency benefits offered by chilled beams are to be recognized. This document explains why low supply air dew points are required and how the SEMCO Pinnacle® system is uniquely suited to achieve these conditions in the most cost effective, energy efficient manner.
