for cold-water condenser systems. Equipment costs for fixed-tubesheet and floating-head
heat exchangers are given in Figs. 5 and 6 for heat transfer surface areas (A ) from 300

to 1500 ft . The equipment costs are in July 1988 dollars. The cost of auxiliary equipment
includes ductwork, dampers, fan, and stack costs, which can be obtained from another
chapter of this handbook series specifically dealing with cost estimations (24).
For condenser systems requiring a coolant based on Table 1, Table 5 can be used to
estimate the total capital cost (RTCC) of a refrigerant system, as a function of refrig-
eration capacity (Ref) and condensation temperature (T ). This cost must be added to
con
the condenser capital cost (TCC) obtained from Fig. 6 or Fig. 6 and Table 4. Although
refrigerated units are often sold as packaged systems, splitting the cost of the basic
condenser system and refrigerant system in this manner allows for more flexibility in
estimating the cost of a given system. A refrigerant system may not be necessary for
