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…
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.…
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…
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…
The oil pump and oil reservoir are contained within the unishell. Oil is pumped through an oil filter-cooler that removes heat and foreign particles. A…
The dehydrator removes water and noncondensable gases. It indicates any water leakage into the refrigerant (see No. 6 in Fig. 8-11). This system includes a…
Refrigerant liquid from a sump in the condenser (No. 24 in Fig. 8-11) is subcooled by passage through a line in the cooler (No. 27…
The machine compressor continuously draws large quantities of refrigerant vapor from the cooler, at a rate determined by the size of the guide-vane opening. This…
A chiller is part of a condenser. Chillers are used to cool water or brine solutions. The cooled (chilled) water or brine is fed through…
