CCN examines what's happening in the chiller space to keep operational costs to a minimum.
Cosair Australia principle, Matthew Cosgrove, who has been in the business for more than 30 years, has noticed a move toward new 4 pipe heatpump recovery, all in one chiller.
“This multipurpose machine will provide all the chilled and hot water from the one unit; no gas boiler or gas reticulation required,” he said.
“It is extremely efficient with substantial running cost savings to the client over a traditional solution.
"Aermec lead the way in this exciting technology with their NRP range which has a cooling capacity up to 480 kW.”
Aermec is a well known innovator overseas with one of the largest test facilities for air conditioning applications in Europe.
The 2.200m3 laboratory is both Eurovent certified for Europe and AHRI certified for North America. Air and water-cooled Chillers and Heat Pumps, Air Handling Units, Indirect Evaporative Coolers and Dry Coolers can all be tested, with an added Data Hall simulator chamber allowing realistic testing of Data Centre applications.
Vertiv ANZ data centre solutions director, Mark Deguara, said another recent trend is the modularisation of chillers.
As organisations continue to move towards CAPEX and ‘pay-as-you-grow’ models of spending, Deguara said many organisations don’t want to pay outright for the full chiller capacity from day one or deal with the potential inefficiencies of running a large chiller at small loads.
“The challenge comes into design and allowing for the ability to grow this capacity. That means that when this need does come, the chiller must be deployed in a very short space of time to ensure the data centre is supported," he said.
“Providers need to think about how they can quickly deploy, remove and redeploy chillers to support these needs.
“The other key factor is how to manage multiple chillers operating together and the importance of integrated controls.”
