1 PRODUCT BROCHURE Fixed Helical Swirl Diffuser HSC-FD HSC-FD : 07 smartemp.com

2 DESCRIPTION The SMARTEMP Fixed Helical Swirl Diffuser, type HSC-FD, produces highly inductive swirl discharge, diffusing the supply air stream radially with fixed horizontal discharge and strong mixing characteristics into the space. The patent pending design delivers high levels of draught-free comfort well suited to both constant volume or VAV applications, inclusive of low temperature or cold air supply air systems with a minimum supply-to-room temperature differential of - K including turndown to approximately %. Helical Twist The diffuser comes standard with a square face (figure ), or may optionally be ordered with a round face. The cambered leading edges of the twenty off-set radial vanes reduce the sound power level and pressure drop, improving aural comfort and saving fan energy. Cambered Leading Edge The vane tips feature helical twist (figure ) that reduces pressure drop, allowing the airflow rate to be increased, thereby reducing the number of diffusers required in the space. This unique feature also reduces the minimum Figure Fixed Helical Swirl Diffuser HSC-FD : 07 Figure

3 CONSTRUCTION - M Rivet Nut - Spigot - Connection Box - M Thread Rod - Reducer (Optional) - HSC-FD Swirl Diffuser 7 - Perforated Face (Optional) permissible VAV turndown to % at - K cooling or % at - K (based on Pa maximum total pressure) and enhances stable operation under low supply air temperature conditions. The HSC-FD diffuser may be flush mounted in a ceiling or freely suspended (ie no Coanda attachment to the ceiling required). Typical discharge height ranges from.0 to. m, depending on diffuser size and airflow. 7 The highly inductive swirl discharge benefits heating performance by strongly diluting supply air with cooler room, thereby diminishing supply air stream buoyancy. The maximum recommended differential between supply air and room air is a function of diffuser size, discharge height and airflow rate. The HSC-FD swirl vanes form a flush surface with the surrounding flat diffuser face, which may be square or round, and which may be optionally screened by a perforated face. The diffuser is made of powder coated steel and is available with nominal neck diameters of 0 mm, mm and 00 mm. Optional reducers are available to reduce effective neck size for decreased airflow rates. Reducers Reducers can be inserted into the neck from behind, Figure reducing the effective neck size to suit reduced airflow rates, especially in low air quantity VAV applications (figure ). Reducers allow a largely uniform diffuser aesthetic to be achieved by enabling the use of a common diffuser size even where airflow rates between diffusers vary widely. The ability to simply change reducer size also provides future-proofing for refurbishment and fit-out changes. Five reducer sizes are available for size DN00 and six for size DN. Fixed Helical Swirl Diffuser Reducers are not available for size DN0. HSC-FD : 07

4 Discharge Pattern Segment covers that blank one half, two opposed quarters, or one quarter of the diffuser vanes are available to reduce the discharge pattern from 0 to 80 (-way asymmetrical), or x 90 (-way symmetrical), or 70 (-way) so as to allow for diffuser placement in corners, in corridors, or close to a wall, respectively (figure ). Segment covers reduce the diffuser airflow rate. Segment covers may be used in combination with reducers where further airflow rate reductions are required. Reducer Mode of Operation The highly inductive swirl discharge of the HSC-FD produces rapid discharge velocity decay as the total supply air stream mass flow rate increases due to strong entrainment of secondary air from the room into the primary air stream. Effective air changes per hour are increased. Consequently, at any given airflow rate, the HSC-FD swirl diffuser is suitable both for long throws (due to the high momentum of the supply air stream) as well as short throws (due to the air stream's low velocity) making it an extremely adaptable diffuser, well suited to a broad range of applications and fit-out changes. Strong dilution of the supply air stream with large quantities of room air provides rapid supply air stream temperature equalisation and hence density equalisation with room air, preventing cold air dumping in summer and minimising warm air stratification in winter. The resultant low velocity room air motion with uniform temperature distribution throughout the occupancy space produces high levels of thermal comfort (no cold and draughty or hot and stagnant spots). x x a: -way asymmetrical blow Figure x s: -way symmetrical blow Centre-line spacing to wall: DN x DN x Figure x w: -way blow Fixed Helical Swirl Diffuser HSC-FD : 07

The supply-to-room temperature differential when cooling is - K. Select 0 L/s for input into the nomogram. Select no collar (Reducer 0). Select m discharge height and L/s/m specific airflow, resulting in a maximum heating temperature differential ( Tmax) of + K. As the diffuser is freely suspended, Tmax.freely suspended Tmax.heating /. +.7 K, based on 00% high level return air. (Even 00% low level return air will only increase Tmax.freely suspended to +. K, which is not sufficient for heating. Consider using the Smartemp HSC-AD instead if heating is required.) The total pressure (Pt) is 8 Pa, inclusive of side-entry connection box pressure loss. Select m discharge height twice (once in the grey zone; once in the white zone). Select - K cooling. 7 Select - K cooling and m discharge height. 8 For an auditorium, select ADPI = 9%. The minimum recommended centre-line distance (Cmin) between two adjacent diffusers is 7.0 m; and hence. m to walls. The minimum recommended discharge height (Hmin) is. m. The maximum recommended centre-line distance (Cmax) is m (ie the lower of m for - K cooling and m for m discharge height); and hence m to walls. 9 The A-weighted sound power level (LW) per diffuser is 8 db(a). As this is a large volume auditorium (and not an office, which typically has approximately 0 db room absorption) the sound pressure level (LP) based on 0 db room absorption should not be used (ie only LW should be provided for acoustical calculations).
