Challenge
Telstra is Australia’s leading telecom provider and as part of that service, they have many thousands of telephone exchanges that require cooling during the summer. With the advent of fast communications and data transfer for commerce and national security, these systems are required to be exceptionally reliable and this is now reflected in the design of the support infrastructure.
Solution: Climate Wizard Pre-Cooling
The air conditioning design for this exchange makes use of economiser operation when appropriate in the shoulder seasons and the Climate Wizard provides the first stage of cooling as the summer heat builds. The refrigerated second cooling stage will then come on line as required, while the Climate Wizard continues to provide its full cooling capacity.
