Cost Implications

System Design Options

Several considerations should be kept in mind when determining sizes for new systems. As pipe size is decreased, so are valve and specialty sizes and costs. Remember that reducing pipe size increases pressure drop. Keep a balance between first cost and operating costs. This can significantly reduce the system retrofit costs because existing pipes may be used.

In both cases, either reusing an existing tower, or reusing existing chilled water piping, the design engineer can often help reduce total project costs using the existing infrastructure by selecting a chiller with a higher temperature differential.

By reducing either chilled- or condenser-water flow rates, the following installed-cost reductions are possible:

•Reduced size of pumps, valves, strainers, fittings, and electrical connections

•In new systems, reduced pipe sizes

•In existing systems, more capacity from existing chilled-water piping

•Reduced cooling-tower size, footprint, and fan power

If a physically-smaller cooling tower is selected using low flow, its reduced footprint can benefit building owners in a number of ways:

•Reduced real estate requirements (often more important than realized)

•Reduced structural requirement, since the amount of tower water is reduced

•Reduced excavation and material costs in the case of a large, built-up tower with a concrete sump

•Improved aesthetics because of the reduced tower height

In addition to reducing installation costs, operating cost reductions for the whole system are also available. Due to a smaller pump and/or tower, the pump and tower operating costs can be reduced substantially with less adverse impact on the chiller operating cost. Analysis programs such as EnergyPlus, eQuest, TRACE™, or System Analyzer™ software can be used to determine annual operating costs. Nordeen and Schwedler11 showed that operating costs for chilled-water systems using absorption chillers can benefit greatly from reduced condenser-water flow. Figure 23 shows operating costs as generated with System Analyzer analysis software.
