Variable volume terminal units, type KS Description Koolair boxes type KS are air volume control terminal units for use in single duct installations. KS boxes consist of a cabinet constructed of galvanised steel-sheet with interior thermal-acoustical insulation of fibreglass, fire resistance M1 not inflammable. They comprise of two connections, one circular or oval at the inlet and another rectangular at the discharge side. Also available is an additional plenum at the discharge side with various connections: circular, oval or rectangular, up to a maximum of five (see table on page 6). The...

KS units are usually installed in the false ceilings of the rooms to be conditioned. In their design this fact has been taken into account, resulting in a minimum height. To facilitate the mounting of the units their length was also considered important and is therefore kept at 610 mm for all sizes. Indicate size from 100 to 8000. Re-heating coil with hot water. Electrical re-heating coil. Product code: Examples: KS-200-1 Standard supply unit, size 200 with one rectangular discharge duct. KS-200-7-P-W Supply unit with two lateral discharge ducts, perforated plate in interior and...

KS-KSL Coefficient to transform the differential pressure reading into air flow rate. Size In the following table the constants are presented which are used to calculate the air flow rate based on the differential pressure, measured by the probe situated in the inlet duct of the KS box, according to the following formula: Q = C •VPd Q = air flow rate in m3/h C = constant (see table) Pd = differential pressure at probe in Pa Comments: * Oval discharge. Maximum diameter lateral discharge: 315 mm. When lateral discharges are incorporated the length is 915 mm. For sizes 6000 and 8000 circular...

Duct connection discharge side The rectangular discharge can be connected to the duct as shown in the figure. In this way the exterior height of the duct is less than that of the KS and even permits exterior duct insulation without superseeding the height of the terminal unit. Detail duct connection Re-heating coil mounting In the standard configuration the re-heating coil is mounted at the discharge side of the KS unit on a 25 mm wide flange by means of screws. This way of mounting adds 50 mm to the height of the KS unit. The coil which is mounted in this configuration has a 60 mm pitch...

Selection tables In the following tables (1 to 10) all data are presented which are necessary for a correct selection of the KS terminal units. Data common to all tables: Diam.(mm): diameter of the circular inlet duct connection. Pmin (Pa): minimum pressure at the inlet of the KS, equivalent to the pressure loss of the box with the damper fully open. Q(m3/h) (l/s): Air flow rate for which the unit is to be selected. Reverberation room Determination of sound power regenerated by the KS. In this table the sound pressure level in the room is given expressed in NC (value of the NC curve...

Table n°6 In this table the sound pressure level in the room, due to the noise radiated by the KS-unit, is given in dB(A) for various air flow rates and for pressures from 100 to 1000 Pa. To obtain these values a 10 dB/octave attenuation has been assumed for the false ceiling. Tables n°7 and 8 These tables are similar to the former, except that the sound pressure levels are referred to the NC and NR curves respectively. Tables n°9 and 10 Sound power levels (dB) are given for the radiated noise for the octave bands from 63 to 8000 Hz. Determination of the attenuation due to the KS units. ISO...

KS-KSL Variable volume terminal units, type KSL Koolar unit type KSL is a KS unit with an extension of the insulation part behind the damper to improve its acoustic characteristics. Therefore, all information corresponding to the KS units is common, except for dimensions and acoustic data. Indicate size from 100 to 8000. Indicate according to table on page 6 If not indicated, he interiorfinish will be fibreglass with neoprene film. Perforated plate in interior. Protection of the insulation with "melinex".
