| Abstract | In this study, steady state models were developed to simulate
reciprocating and centrifugal compressor chiller systems, coupled with
cooling tower. Additionally models were developed to simulate a chiller
system coupled with chilled water storage, operating under different
storage modes.
The reciprocating chiller model was developed using data from a
catalog. The centrifugal chiller model was developed for a chiller in the
AIT chiller system. Using actual data from the AIT system, the
centrifugal compressor was modelled, and further readings were taken under different conditions to validate the model predictions.
Through the actual readings taken, and the models predictions, some
improvements in operating practice were suggested.
The chilled water storage simulation was done, considering a load
curve similar to that of AIT's load on a single chiller. Three different
storage operating modes were considered, and these were evaluated using
three different electricity rate structures.
Replacement of the large chiller by a smaller one, coupled with
storage, proved to be the most worthwhile investment, with a payback period of 4 to 5 years for all three electricity rate structures. These
results showed it would be feasible for AIT to consider installing chilled
water storage. |
