Sungard has successfully implemented the replacement of the existing water cooled Luke chillers and Muller cooling towers mechanical plant, with three new 1100Kw evaporative cooled and highly efficient Smardt-Powerpax Chillers.
The integrating evaporative pre-cooling capability of the new chillers lowers the incident air temperature on the coil to dramatically reduce energy consumption, effectively shifting heat rejection from ambient dry bulb towards ambient wet bulb. In warmer, dryer climates, Smardt-Powerpax reference sites show further savings compared with normal Smardt-Powerpax air-cooled operation. The efficiency is comparable to a water-cooled system eliminating the need for a recirculation system including cooling tower, cooling water piping, pumps and water treatment system.
Smart-PowerPax advise that the units installed by O’Connors on behalf of Sungard Data Centre are the “only evaporative-cooled chillers on the Australian market with an unmatched efficiency in a range from 300 – 1200kW cooling capacity”. The new evaporative pad system installed at the Kidman Park Sungard Data Centre, is estimated to save approximately 23,000kL per annum (if fully loaded), which is equivalent to just over 9 Olympic sized swimming pools which each on average contain 2,500kL.
