Abstract
Recirculating cooling water systems are consist of a cooling tower and
heat-exchanger network which conventionally have a parallel
configuration. However, reuse of water between different cooling duties
enables cooling water networks to be designed with series arrangements.
This will result in performance improvement and increased cooling tower
capacity. Research on recirculating cooling water systems has mostly
focused on the individual components. However, a particular design
method represented by Kim and Smith accounts for the whole system
interactions. In this study, the Kim and Smith design method is
expanded and a comprehensive simulation model of recirculating cooling
system was developed to account for the interaction between the cooling
tower performance and the heat-exchanger network configuration.
Regarding this model and considering cycle water quality through
introducing ozone treatment technology, a modern methodology of
recirculating cooling water system design was established and
developed. This technique, called the integrated ozone treatment
cooling system design, is a superior designed tool based on pinch
analysis and mathematical programing. It also ensures maximum water and
energy conservation, minimum cost and environmental impacts. Related
coding in MATLAB version 7.3 was used for the illustrative example to
get optimal values in cooling water design method computations. The
result of the recently introduced design methodology was compared with
the Kim and Smith design method
