These diffusers rely on a high velocity cyclonic discharge pattern to increase the induction of room air and rapidly dissipate temperature and velocity differentials associated with the supply air stream. Their unique design enables them to create room air induction ratios significantly greater than those of conventional diffusers. involving high air changes or high sensible loads. They are also capable of supplying significant airflow quantities (see page 34 for high air change applications) while minimizing space air velocity disturbances in applications such as animal research laboratories. Swirl diffusers have been succesfully used in European process and comfort conditioning applications for over thirty years. They are widely employed for critical process applications such as fume hood laboratories, clean rooms, industrial drying facilities and hospital operating room applications. In fact, they are ideal for use in any application 2 Swirl diffusers are available in a variety of shapes and sizes to fit any application or aesthetic requirement. Unlike conventional outlets, swirl diffusers do not require a ceiling surface to properly operate. Certain models incorporate automatic adjustment of their discharge pattern to facilitate heating and cooling applications in high ceiling areas. Swirl diffusers can also be fitted with high efficiency particulate filters for clean room applications (see page 38 for further details).

A series of linear slots are aligned radially around the center of the diffuser face. These slots divide the supply air to the diffuser into a number of high velocity jets. This increase in supply jet surface area enables the diffuser to induce large quantities of room air. In most designs, the slots are subdivided along their length to further enhance the induction rate. The supply jets are also discharged in a cyclonic pattern, which forces the air jets to travel in a rotating manner around the diffuser center. During this travel, the jets induce additional room air and rapidly dissipate the velocity and temperature differentials between the jet and the ambient air, minimizing the distance at which high velocities and/or drafts exist. This high induction performance also enables them to perform equally well without an adjacent ceiling surface, making swirl diffusers an excellent choice for areas where exposed ductwork is employed. The unique discharge characteristics of swirl diffusers make them ideal for high air change applications involving air change rates up to eighty (80) per hour. A section of this brochure is dedicated to such applications (see page 34). TROX also employs swirl technology in diffusers designed for raised floor and underseat applications.

In accordance with this, TROX has tested its swirl diffusers under a variety of supply air conditions and is able to provide data that will enable the designer to estimate such local thermal conditions. Local velocities can be estimated by using the throw data in the individual diffuser performance tables. The table below presents a thermal decay factor (KT) that can be used to estimate local temperatures various distances from the diffuser. The following equation to predict the temperature differential between the supply air jet and the ambient air at any given distance X from the diffuser discharge: ∆TX = KT x ( AEFF / (X1 or X2) x ∆TZ where ∆TZ is the initial temperature difference between the supply and room air. AEFF is the effective outlet area of the diffuser and is listed in the individual diffuser performance tables. Nomenclature A, B Distance between opposing diffusers B A A X2 A/2 Distance from diffuser to point X midway between diffusers plus distance H1 from ceiling X2 Distance from diffuser to point L along wall VZ Jet velocity at point of discharge into room ∆TZ Temperature differential between supply and room air at point of discharge from diffuser VX Local velocity at point X ∆TX Predicted temperature differential between the supply air jet and ambient room air at point X VL Local velocity at point L ∆TL Predicted temperature differential between the supply air jet and ambient room air at point L vZ ∆TZ X1 H1 X1 X1 X X vX ∆TX vL ∆TL L Thermal Decay Constant Diffuser Type TDF TDV VDW RFD RFD-D DCS VDL VDZ Thermal Decay Constant (KT) 1.54 2.00 0.77 0.86 0.85 1.06 1.90 * 1.90 * * Applies to cooling applications only 6 Diffuser Selection Selection Example 1 TDF swirl diffusers (top entry) are to be located (as shown at right) in a laboratory with a nine (9) foot ceiling. The diffusers will handle 650 CFM each and velocities at the top of the fume hood sash (6 foot level) cannot exceed 60 fpm. The supply air is 55 °F and the room temperature is 72 °F. 7 8 4 X2 vZ ∆TZ X1 X1 3 Performance data for the TDF is shown on page 10. A size 605 diffuser is considered first as it can be integrated with the lay-in ceiling grid. X X At 650 CFM, the diffuser produces a throw (to 50 fpm) of 7 feet, therefore, the velocities at points L and X (the top of the hood sash) will be 50 fpm or less. Using the equation for thermal decay (X1 and X2 equal 7 feet): vL ∆TL vX ∆TX L Layout for Example 1 ∆TX = ∆TL = 1.54 x ( .43 / 7 ) x 17 = 2.45 °F Selection Example 2 VDL swirl diffusers are to be used for heating and cooling a convention space. The diffusers are mounted on exposed duct drops 24 feet above the floor and must handle 1200 CFM each. Cool air is supplied at 55 °F while warm air is introduced at 95 °F. The room temperature is to be maintained at 75 °F. Diagrams illustrating the application can be found at the right. 20 10 ∆TZ = -20F 24 vX ∆TX Diffuser selection in high ceiling applications requiring both heating and cooling are usually based on the heating mode as the diffuser must be capable of projecting the warm air stream to the occupied levels of the space. Cooling Mode 6 Performance data for the VDL is shown on page 32. A size 400 unit will perform the required operation at a space NC of 34. 20 10 ∆TZ = +20F Performance of the diffusers in the cooling mode indicate throw values (to a 50 fpm terminal velocity) of about 10 feet, therefore, no drafts should be experienced in the occupied zone (lower 6 feet). The maximum vertical throw of the diffuser shown in the performance table on page 32 represents the vertical projection of the air stream (based on a 20 °F temperature differential). At this point, there is no temperature difference between the supply and room air. For the diffuser being considered, the maximum throw is 26 feet, which indicates that the heated air stream will indeed penetrate the occupied zone. The diffuser selection is valid. 24 6 VMAX ∆TVMAX Heating Mode Layout for Example 2 7 Product Information · Application Product Information Guide Dimensional Information Performance Data Specification Text Ordering Information Features 9 10 11 11 • TDF series features a fixed swirl discharge pattern.

Figure 1 illustrates a collision between two air streams from conventional ceiling diffusers. The velocity measured at height (H) is dependent upon the distance (X) between the diffusers and increases as that distance between is reduced. This relationship is depicted in Figure 2. Although their projection is significantly less, swirl diffusers operate in a similar manner when located far enough apart that their radial swirl fields do not intersect. The performance data in previous sections of this leaflet is based on such spacing. However, when the diffusers are located such that their swirl fields intersect (see figure 3), a secondary swirl field is formed which increases the induction of room air. As such, room velocities can actually be reduced by locating the diffusers in very close proximity to one another. This should be limited to a single direction and 8 to 10 feet spacing maintained in the perpendicular direction (see figure 4 below). Swirl diffusers can be employed to deliver air change rates in excess of 80 per hour, while maintaining minimal velocity disturbances in the occupied or process areas of the space. Performance data presented on pages 36 and 37 (and the examples on page 35) aid designers in selecting swirl diffusers for high air change applications. TROX also provides designers with selection and location software supporting high air change applications. Contact your local TROX representative for further details.

Swirl Field Figure 3: Intersection of Swirl Fields 34 Figure 4: High Density Mounting For High Air Change Rates Diffuser Selection · Examples High Air Change Selection Procedure Swirl diffusers for high air change applications may be identified and selected according to the following procedures: 1. Identify the air change rate and maximum allowable velocity for the application under consideration. 2. Identify the types and sizes of swirl diffusers that are capable of the specified performance using the table on page 36. 3. After identifying diffuser type and size, consult the table on page 37 to determine the maximum outlet airflow rate that corresponds to the desired performance. 4. Calculate the required number of diffusers for the application, rounding up to the next number that results in an equal diffuser distribution in each row For example, if three rows (but onlyseven outlets) are required, increase the number of outlets to maintain equal distribution. If a single row (of seven outlets) is involved, the calculated number of outlets is sufficient. Each outlet handles the same CFM. 5. Locate diffusers in an array such that the distance from any wall to the center of the nearest diffuser is at least 3 feet. Diffuser spacing may be anywhere from 3 to 6 feet in one direction, while the perpendicular spacing is limited to at least eight (8) feet. Note that maximum air change capacities on page 36 are based on a 3 ft by 8 ft spacing and may be reduced as spacing is increased. 8 ft. 3 ft (min) Diffuser Layout for High Air Change Applications 8 ft. High Air Change Selection Example 1: TDF (size 605) swirl diffusers are to be used in a laboratory with nine (9) foot ceilings. The space (16 ft x 15 ft) requires 40 ACH-1 (1440 CFM) and velocities at the top of the hood sash (6 foot level) cannot exceed 50 fpm. A quick check verifies that the maximum air change rate (page 36) for a TDF/605 installed 3 feet above the level where velocities are limited to 50 fpm is 58. Airflow data for the TDF/605 (see page 37) indicates that the maximum outlet airflow that may be employed while limiting velocities (3 feet below the diffuser) to 50 fpm is 240 CFM. Therefore, 6 diffusers must be used, handling 240 CFM each and located as shown. High Air Change Selection Example 2: VDW (size 605 x 48) swirl diffusers are to be used in a clean room with a nine (9) foot ceiling. The space (15 ft x 14 ft) requires 70 ACH-1 (2205 CFM) and velocities at the 6 foot level cannot exceed 60 fpm. A check verifies that the maximum air change rate (page 36) for the selected diffuser installed 3 feet above the level where velocities are limited to 60 fpm is 74. Airflow data (page 37) for the VDW (size 605 x 48) indicates that the maximum outlet airflow that may be delivered while limiting velocities (3 feet below the diffuser) to 60 fpm is 305 CFM, so 8 diffusers must be used, handling 275 CFM each and located as shown. 3 ft (min) 3 ft. 3 ft. 3.5 ft 5 ft.

These terminals incorporate any of the high efficiency filters shown below, and are offered with either TDF or VDW swirl diffuser faces. Sizes are available for terminal airflow rates as high as 625 CFM (based on a 1.0 in.w.g. clean filter pressure requirement). F640 Series Filter Terminals F640 series terminals incorporate a side entry collar and are intended for flush ceiling mounting. These terminals incorporate any of the high efficiency filters shown below, and are offered with either TDF or VDW swirl diffuser faces. Sizes are available for terminal airflow rates as high as 625 CFM (based on a 1.0 in.w.g. clean filter pressure requirement). F640 Series F655, F656 and F657 Series Terminals F655 and F656 series terminals also incorporate a side entry collar but include an integral motorized shut-off damper. This allows filter service without effect to the airflow supply to other terminals. In addition, it may be used to shut-off selected terminals during unoccupied periods in order to increase filter life and conserve fan energy. F657 terminals incorporate a mechanical volume regulator which compensates for filter loading and maintains a constant volume airflow through the terminal. No external power or control connections are required. All terminals are offered with either TDF or VDW swirl diffuser faces. Sizes are available for terminal airflow rates as high as 625 CFM (based on a 1.0 in.w.g. clean filter pressure requirement).
