2 A I R D I S T R I B U T I O N S P E C I A L I S T APPLICATIONS FLOWTECH Linear Slot Diffuser (LSD) is a high capacity slot diffuser suited to a wide range of applications. With its pleasant aesthetic appearance it can be used in variety of prestigious locations such as Lobbies, Dinning Halls, Hotels, Palaces and Buildings Entrances where aesthetic is architecturally critical. For this purpose FLOWTECH LSD can be supplied in a straight or curved shape with a wide variety of powder coated colors. Functionally, Linear Slot Diffusers are used in large open areas where perimeter supply or return is required. For this purpose, FLOWTECH LSD is provided with unique curved design of air deflecting vanes which can be adjusted as required to achieve precise control of air flow direction. Usually directional control is required towards perimeter heat source or away from adjacent glass areas. With its steady performance at variable air flow rates, FLOWTECH LSD can be effectively used as part of VAV systems. For this purpose, FLOWTECH LSD can be combined with unitary plenum boxes of designer choice. FLOWTECH LSD can be used as supply air diffuser, return air diffuser or dummy ceiling diffuser for decorative purposes. Rev. 0:00/ E-

9 A I R D I S T R I B U T I O N S P E C I A L I S T GENERAL NOTES Pages onwards give performance data for all models and variants, and unless otherwise stated the following general notes apply: Throws shown are to three terminal velocity of 0.m/s, 0.m/s, 0.7m/s, (0fpm, 00fpm, 0fpm) with coanda effect across a flat ceiling, and with supply air at conditions with max DT=0k cooling. For standard room height of.7 metres, throws should be taken as the distance to the nearest wall (minimum plan dimension, MPD), or to half the distance between linear slot diffuser centres. 4 Care should be taken to avoid 'dumping' on cooling cycles is low jet velocities at the diffuser core. In order to avoid this it is advisable to ensure that neck velocities do not drop below 0.7m/s. The accoustical data were tested in accordance to ASHRAE standards, the octave band sound power levels obtained were plotted to determine the point of tangency with the highest rank Noise Criteria curve (NC) to establish the NC. Noise Criteria ratings were determined by subtracting room absorption of 0dB from the sound power level data. NC, and Pressure values shown, are based on a slot diffuser where the pattern control vanes were set for maximum horizontal throw for one of the test and positioned fully open for the vertical throw test. The hit and miss damper is aligned for a fully open position. The damper should only be used for fine balancing, as for every doubling of pressure there is a resulting increase in the noise level of +9dB for supply, or +db for exhaust. 7 The following tables include the results of tests conducted on samples of air terminals. The test results include Noise Criteria (NC), static pressure versus air flow, throw and effective area. Extrapolation was used to obtain the performance for other sizes and other parameters within the range of products mentioned above. Test method included in ETL report.
