8 SECTION 3 Computer Room Floor Grille Type CFG/AFG Floor grille types CFG and AFG are specifically developed for mounting in Raised Access Floors in such areas as Computer Rooms, where load and damage resistance are of the utmost importance. Having a heavy duty construction, they can replace 600mm square floor tiles. Grille border depth can be specified to suit the type of floor system used. A range of surface finishes is available. The type CFG is a fan assisted computer room floor grille that eliminates hotspots and reduces risk of equipment failure by providing up to 5kW of cooling per cabinet. Floor Grilles The type AFG is a static grille assembly which can handle supply air or alternatively extract air and be fitted with rear opposed blade damper assembly for air volume flow control.

The floor void static pressure must be considered in the selection process (see Potential cooling below). Sufficient void air (cooled by others) must be available to be drawn by the grille at the specific point of need. Structural performance The 125mm deep unit will provide the following strength against the performance specification: CFG Acoustic Data Sound power level for one CFG 76dB(A) In an area with several units the noise level will increase due to multiple sources. To allow for this and room attenuation an assessment should be made by an acoustic engineer to ensure required room noise levels are achieved.

38 Disc Valves SECTION 10 Disc Valve Type LVS Z-LVS The disc valves consist of a valve ring, central disc and installation subframe. To guarantee a perfect seal, the valve ring is fitted with a peripheral sealing strip. A bayonet fitting is used to mount the unit in the installation subframe. The air volume flow is adjusted by rotating the central disc which alters the gap between the disc and the valve ring. The central disc is held in position with a locknut.

40 Swirl Diffusers SECTION 11 Swirl Diffuser Selection Methodology Swirl diffusers offer a high induction air distribution method that enables the highest comfort criteria to be achieved. The following range of diffusers each discharge an air stream horizontally across the ceiling. The entrainment and expansion takes place rapidly, and the velocity decay of the air-stream occurs in direct proportion with the distance from the device. High turbulence occurs immediately within the proximity of the diffuser, which allows high air change rates to be successfully supplied into the room. With careful selection swirl diffusers can handle up to 30 air changes per hour while still satisfying relevant comfort criteria. Minimum Diffuser Centres A, B or C 2.7m 1.0m X V H1 Occupied Zone The layout and centres of the swirl diffusers must be carefully considered to ensure maximum comfort is achieved. We have provided three alternative arrangements for positioning diffusers, selection methods 1, 2 and 3. Each of the selections will ensure that the maximum terminal velocity in the occupied zone (VH1) will not exceed 0.25m/s, 1.0m below ceiling. 40

52 Swirl Diffusers SECTION 11 Type TDV The diffuser face of the type SilentAIR offers a high volume flow rate at low sound power levels. The horizontal swirl-type discharge of the supply air ensures high induction and hence rapid reduction in jet velocity and temperature differential. Suitable for supply air temperature differentials up to ±10 K. Depending on requirements, the diffuser can be supplied with a circular or square face and with either white or black air control blades. For the air connection a plenum box is used.

56 Jet Nozzles SECTION 12 Type DUK - Standard Supply Jet nozzles type DUK are suitable for almost all situations because of the wide range of variants available. Fixed construction type DUK-F consists of a nozzle with fixing holes. Adjustable construction type DUK-V consists of a spherical discharge nozzle mounted flange and circular spigot for direct connection to a circular duct. The nozzle can be adjusted manually up to max. 30 in any direction. The adjustment can be motorised with an electric or pneumatic actuator. With an actuator the nozzle can only be rotated in one plane up to 30 upwards (cooling) and up to 30 downwards (heating). For full details see publication 1/5/EN/...
