Cooling Water Alternatives
The most common method of supplying cooling
water is the direct connection of the cooler to the
water main. In this method the inlet of the cooling
coil (or its water control valve) is connected directly
to the city water supply. This method of connection
has the lowest capital cost of aU the cooling water
supply systems. Nothing more than interconnecting
piping is required. Figure 1 is a graphical
representation of this type of connection. Fresh
water from the main flows through a single pass of
the coil. Water from the cooler’s outlet goes to drain.
