By lifecycle. Chilled beams have become a more common design bringing chilled water to the perimeter of a space under a raised strategy for controlling the perimeter zone...

InFloor Chilled Beam:Perimeter Solutions 6/17/11 4:42 PM Page 4 Improve Design & Performance Underfloor Air Distribution and In-floor Active Chilled Beams Underfloor Air Distribution (UFAD) In-floor Active Chilled Beams Improve UFAD Underfloor Air Distribution (UFAD) uses a raised floor to create Overall, placing a chilled beam at the perimeter can simplify the an air distribution plenum to improve energy efficiency and design of a UFAD system by eliminating the concern for thermal modularity of design. UFAD uses stratified airflow to improve decay. Typical UFAD designs use spider ducting to...

InFloor Chilled Beam:Perimeter Solutions 6/17/11 4:42 PM Page 5 In-floor Active Chilled Beam Applications Typical In-floor Active Chilled Beam Design In-floor Active Chilled Beams allow for complete seamless integration. The beam can be installed as a continuous linear grille along the perimeter or segmented only where needed. Using chilled beams reduces the number of diffusers in the perimeter zone and eliminates the need for equipment to be installed under floor panels. With In-floor Active Chilled Beams you gain all the aesthetic benefits of a raised floor including the elimination of the...

InFloor Chilled Beam:Perimeter Solutions 6/17/11 4:43 PM Page 6 Tate In-floor Active Chilled Beams With a wide product range the In-floor Active Chilled Beam offers many benefits over other perimeter solutions commonly used in raised floor office environments. The image below shows the above and below floor visual of this easy to install solution that offers buildings in almost any climate a highly efficient perimeter heating and cooling solution. Carpet overlays part of chilled beam housing. Flanged edge for mounting to raised floor panel. Cut raised floor panel. 1” 7.625” Anodized aluminum...

InFloor Chilled Beam:Perimeter Solutions 6/17/11 4:43 PM Page 7 Product Options 2-Pipe The 2-Pipe model is designed to create an efficient and simple solution to meet perimeter heating and cooling needs. A supply and return water connections are located on opposite ends of the chilled beam. Hot and Chilled water can be alternately passed through these based on the building demands and the facility operators control. By time modulating the air valves and water valves controlled by a thermostat located in the space, one can meet the perimeter demands of any season. 4-Pipe The 4-Pipe model is designed...

InFloor Chilled Beam:Perimeter Solutions 6/17/11 4:43 PM Page 8 2-Pipe: Modes of Operation Cooling Mode The Thermostat detects a cooling condition and the Aquastat detects chilled water: The control box will begin to time modulate the air valves and open the water valve. Chilled water flows through the coil, and air passes through the unit in a time modulation of six second full open bursts. Once the thermostat detects that the occupied space has reached set point, the system will return to suspend mode, closing the air and water valves awaiting further system demands. Heating Mode The Thermostat...

InFloor Chilled Beam:Perimeter Solutions 6/17/11 4:43 PM Page 12 Applying In-Floor Active Chilled Beams It is important to select a Chilled Beam that meets both load and architectural needs. Chilled Beam selections have been made to T fulfill maximum load within a 10 ft. perimeter zone. Capacities chilled water temperature, hot water temperature, inlet air our space into zones for a proper load calculation: a conference temperature, flow rate, and room conditions. We have broken were determined based on the given conditions listed below: space, an open office area, and a private office. Next,...
