17 RECOMMENDED UNIT LAYOUT It is advisable to select and design the best layout or location to avoid air recirculation. Recirculation occurs when some of the hot moist discharge air leaving the cooling tower flows back into the fresh air inlet. The following guidelines will provide the best location or layout which will minimize recirculation, maximize fresh air flow and allow adequate maintenance accessibility. A. SINGLE UNIT INSTALLATIONS The best place for EX-S Series Cooling is in an open space. However, when this is not possible, correct layout guidelines must be followed to provide satisfactory installation. INCORRECT: Wind effect with top of unit lower than top of wall Ensure that the top of the cooling tower is higher than any adjacent walls, buildings or other structures. Figure 1(a) and 1(b) are examples of incorrect installation. These conditions can be corrected by elevating the unit on structural steel/concrete plinths so that the top is higher that the wall as shown in Figure 1(c). When a cooling tower is located near a wall, consideration must be given to the clearance distance between the air inlets of the tower and the wall structure(s). See Figure 2, Recommended Dimensions D1 and D2. The minimum dimensions, D1 and D2, as shown in Table 1 must be maintained to ensure that the unit is provided with adequate air flow. In some installation, consideration must also be given to access to the unit for maintenance. Room must be provided for piping, removals of access panels, etc. CORRECT: Installation elevated so that top of unit is higher than top of wall Sometimes other pieces of equipment such as pumps, filters, piping etc are placed in front of the air inlets. These obstructions should not be located any closer than the minimum dimensions in Table 1.

18 RECOMMENDED UNIT LAYOUT B. MULTIPLE UNIT INSTALLATIONS When more than one cooling tower is installed at the same location, recirculation becomes a bigger problem. With the installations of two cooling towers, they should be placed end to end with the narrows ends adjacent as shown in Figure 3. Another method is to locate the units side-by-side with the longer sides parallel to each other as shown in Figure 4. In either configuration, the distance between the units must provide adequate airflow as well as room for piping to the unit and access for maintenance. The minimum dimensions are as listed in Table 2. C. SPECIAL ENCLOSURE INSTALLATION 1) Solid Wall Enclosure or Wells Figure 5 shown a cooling tower is installed in a well, When considering a multiple-call unit located in a well, the D5 and D6 dimensions, found in Table 3, must be used as absolute minimums. The unit should be oriented so that the air flow uniformly to the air inlets on all louver sides of the unit. The air discharge of the unit must be level with or higher than surrounding walls.

The inlet air will be drawn from the top as well as through the louvers or slots. When considering a multiple-cell unit located in a louvered wall enclosures, the D7 and D8 dimensions, found in Table 4, must be used as absolute minimums.
