The fluid cooler uses a mechanically induced draft, crossflow technology. And, the fill media is located above the coil. The process fluid is pumped internally through the coil. Recirculating water is cooled as it passes over the fill media, as shown in Fig. 8-28. The process fluid is thermally equalized and redistributed over the outside […]

The fluid cooler is one of the most efficient systems for industrial and HVAC applications (see Fig. 8-26). By keeping the cooling process fluid and in a clean, closed loop it combines the function of a cooling tower and heat exchanger into one system. It is possible to provide superior operational and maintenance benefits. The […]

Crossflow towers, as shown in Fig. 8-24, have a fill configuration through which the air flows horizontally. That means it is across the downward fall of the water. The water being cooled is delivered to hot-water inlet basins. The basins are located above the fill areas. The water is distributed to the fill by gravity […]

The atmospheric type of tower does not use a mechalnical device, such as a fan, to create air flow through the tower. There are two main types of atmospheric towers—large and small. The large hyperbolic towers are equipped with “fill” since their primary applications are with electric power plants. The steam driven alternator has very […]
Read More…Acooling tower is a device for cooling a stream of water. Evaporating a portion of the circulating stream does this. Such cooled water may be used for many purposes, but the main concern here is its utilization as a heat sink for a refrigeration-system condenser. A number of types of cooling towers are used for […]

The evaporative condenser is a condenser and a cooling tower combined. Figure 8-18 illustrates how the nozzles spray water over the cooling coil to cool the fluid or gas in the pipes. This is a very good water conservation tower. In the future, this system will probably become more popular. The closed-circuit cooler should see […]

Classified by the air-circulation method used, there are two types of cooling towers. They are either natural-draft or mechanical-draft towers. Figure 8-15 shows the operation of the natural-draft cooling tower. Figure 8-16 shows the operation of the mechanical-draft cooling tower. The forced-draft cooling tower shown in Fig. 8-17 is just one example of the mechanical-draft […]
Read More…The following terms apply to cooling-tower systems. Cooling range is the number of degrees in Fahrenheit through which the water is cooled in the tower. It is the difference between the temperature of the hot water entering the tower and the temperature of the cold water leaving the tower. Approach is the difference in degree […]

Cooling towers are used to conserve or recover water. In one design, the hot water from the condenser is pumped to the tower. There, it is sprayed into the tower basin. The temperature of the water decreases, as it gives up heat to the air circulating through the tower. Some of the towers are rather […]

The cooling capacity of the machine is automatically adjusted to match the cooling load by changes in the position of the compressor inlet-guide vanes (see Fig. 8-13). A temperature-sensing device in the circuit of the chilled water leaving the machine cooler continuously transmits signals to a solid-state module in the machine-control center. The module, in […]
