3 YORK Linear Active Chilled Beams Energy Efficiency Delivered YORK linear chilled beams are the air distribution device of choice in high performing energy efficient buildings. Utilizing an integrated sensible cooling coil, active beams reduce the volume of air required for space cooling. A smaller volume of primary air minimizes energy consumed treating outdoor air and nearly eliminates energy wasted by parasitic reheat. When compared to conventional VAV systems a 30% energy savings can be realized. Superior Performance Aerodynamically designed nozzles inject conditioned primary air into the diffuser at high velocity. As the jets of air expand and slow the change in velocity creates a pressure gradient along its boundary. This pressure differential induces room air across the sensible coil within the diffuser. Using Computational Fluid Dynamics (CFD) and extensive laboratory testing the geometry of the YORK linear active chilled beams was refined to maximize induce air flow for optimal energy efficiency. CB-ABL-YK / CB-ALV-YK CB-ALE-YK Low Sound, Low Maintenance Active chilled beams utilize system pressure in their operation, eliminating fans in the space or in the ceiling plenum minimizing overall system noise. With the elimination of fans, active chilled beams have no parts to replace for maintenance. Additionally, since coils are providing sensible cooling only there are no filters to be changed nor drain pans to clean; only periodic vacuuming of the coils to remove lint and dust from the coil and general cleaning of the exposed surfaces. Linear Styling and Flexible Installations The linear design of these beams is such that they can be installed in continuous runs to become a core design feature of a space or project. Perforated or bar grille faces are available to tie into styling of the entire project. Flexible mounting methods allow for direct attachment to the building slab, suspended by hanging wire or by threaded rods. Available border types accommodate standard lay-in, narrow tee and tegular drop face ceiling systems. The CB-ALE-YK is specifically designed for exposed installations with integral coanda plates for ceiling independent air distribution. Available Models: CB-ABL-YK: Standard Linear Active Chilled Beam CB-ALV-YK: Linear Active Chilled Beam with Vertical Coils and condensate tray CB-ALE-YK: Linear Active Chilled Beam for exposed installations 3

24 Guide Specification: CB-ABL-YK Active Chilled Beams 24-inch Width PART 1- GENERAL 1.01 Summary This section describes the active chilled beams Submittals Submit product data for all items complete with the following information: 1. Operating weights and dimensions of all unit assemblies. 2. Performance data, including sensible and latent cooling capacities, nozzle types, primary and total supply (primary plus induced) airflow rates, chilled (and where applicable hot) water flow rates, noise levels in octave bands, air and water side pressure losses and maximum discharge air throw values. 3. Construction details including manufacturers recommendations for installation, mounting and connection. PART 2- PRODUCTS 2.01 General Materials and products required for the work of this section shall not contain asbestos, polychlorinated biphenyls (PCB) or other hazardous materials identified by the engineer or owner Design 1. Furnish and install YORK CB-ABL-YK series two slot active chilled beams of sizes and capacities as indicated on the drawings and within the mechanical equipment schedules. The quantity and length of the beams shall be as shown on the drawings, without EXCEPTION. The beams shall be constructed and delivered to the job site as single units. 2. The face of the beam shall consist of a room air induction section of 50% free area perforated (optional linear bar type) induction section flanked by linear supply slots. The face section shall include hinged fastening on each side that allows the face to be swung opened from either direction for coil cleaning. Faces that are designed to be lifted out are NOT ACCEPTABLE. The entire visible face sections and all visible internal surfaces shall be finished in white powder coat paint or as specified by the architect. 3. Beams shall be provided with side and end details which will allow its integration into the applicable (nominal 24 inch wide) acoustical ceiling grid as specified by the architect. 4. The beams shall consist of a minimum 20 gauge galvanized steel housing encasing the integral sensible cooling coil and a plenum feeing a series of induction nozzles. A single duct connection shall be provided on either the side or top of the unit. The use of multiple duct connections is NOT ACCEPTABLE. 5. Each beam shall be provided with a pressure tap that may be used to measure the pressure differential between the primary air plenum and the room. Airflow calibration charts that relate this pressure differential reading with the primary and beam supply airflow rates shall be furnished with the beams. 6. Beams shall be provided with connections for either 2 or 4 pipe water connections as indicated on plans and schedules. Four pipe configurations shall require separate supply and return connections for chilled and hot water. The coil shall be mounted horizontally and shall be manufactured with seamless copper tubing (½ outside diameter) with minimum.016 inch wall thickness 24

25 mechanically fixed to aluminum fins. The aluminum fins shall be limited to no more than ten (10) fins per inch. The coil shall have a working pressure of at least 300 PSI, and be factory tested for leakage at a minimum pressure of 360 PSI. Each chilled beam shall be provided with factory integrated manual air vents. (OPTIONAL, coil shall be provided with factory integrated drain fittings.) Unless otherwise specified, coil connections shall be bare copper for field sweating to the water supply circuit. Connections shall face upwards, be located near the left end of the beam (when viewing into the primary air connection). (OPTIONAL, the chilled water coil shall be provided with NPT male threaded fittings. These fittings must be suitable for field connection to a similar NPT female flexible hose spigot and shall be at least 1½ long to facilitate field connection (by others). 7. Beams shall be delivered clean, flushed and capped to prevent ingress of dirt 2.03 Performance 1. All performance shall be in compliance with that shown on the equipment schedule. Acoustical testing shall have been performed in accordance with ASHRAE Standard Coils shall be rated in accordance with AHRI Standard 410, but their cooling and heating capacities shall be established in accordance to ASHRAE Standard for the specific application on the inlet side of the submitted chilled beam. 3. Chilled water flow rates to the beams shall be limited to that which results in a maximum ten (10) foot head loss. Water flow velocities through the beam shall not exceed 4 FPS. PART 3- EXECUTION 3.02 Installation 1. Coordinate the size, tagging and capacity of the beams to their proper location. 2. Chilled beams up to six feet in length shall be independently suspended from the structure above by a four (4) threaded rods of 3/8 diameter (provided by the installing contractor). For beams beyond six feet in length, six (6) threaded rods of 3/8 diameter shall be used. The upper end of the rods shall be suspended from strut channels that are a) mounted perpendicular to the beam length and b) at least four inches wider than the beam to facilitate relocation of the threaded rods along their length. The beam shall then be positioned above the acoustical ceiling grid and lowered into the grid module by adjusting the nuts connecting the threaded rods to the beam. 3. Before connecting the supply water system(s) to the beams, contractor shall flush the piping system(s) to assure that all debris and other matter have been removed. 4. Contractor shall perform connection of beams to the chilled water circuit by method specified (hard connection using sweated connection or connection using flexible hoses). 5. Flexible connector hoses shall be furnished by others (optionally by the manufacturer). Hoses shall be twenty four (12, 18, or 24) inches in length and suitable for operation with a bend radius as small as five (5) inches. Connector hoses shall consist of a PTFE lined hose with a wire braided jacket. The hoses shall be suitable for operation in an environment between -40 and 200BF, rated for a least 300 PSI and tested for leakage at a minimum pressure of 360 PSI. Contractor shall assure that the chilled water supplying the beams has been 25
