High efficiency chiller plant for OneAsia
CARRIER HAS COLLABORATED WITH CLOUD-BASED SERVICES PROVIDER ONEASIA TO BUILD THE COMPANY’S FIRST DATA CENTRE EQUIPPED WITH A WATER-COOLED CHILLER SYSTEM.
THE DATA CENTRE in Nantong Industrial Park, China, is 120,000 square metres and includes 846 cabinets with a total load of 10,548 kW.
Carrier’s solution to reduce power usage effectiveness (PUE) includes the design of a high-efficiency chiller plant with four Carrier AquaEdge 19XRV centrifugal chillers, a com- puter room group control system and power distribution system.
The solution also includes Carrier Comfort Network (CCN) controls.
OneAsia is the first data centre project based on a programmable logic controller (PLC) framework for CCN in China.
In addition to participating in the PUE plan- ning, Carrier also provided the data for the annual dynamic load and energy consumption analysis,
as well as group control strategy support. Carrier optimised the design of the entire cooling system of the chiller plant to meet
China’s GB50174 A-level standard.
To enhance the overall energy efficiency of the
chiller plant, Carrier provided the AquaEdge 19XRV chillers with variable frequency drive (VFD) conversion technology to increase the par- tial load by up to 74.4 per cent. The result is improved efficiency and reliability under low ambient temperature.
By optimising the pipelines in the equipment room, improving equipment energy efficiency, and deploying energy-saving designs for the group control system, the annual average opera- tional energy efficiency ratio (EER) of chiller plant system increased from 7.05 to 8.67.
Fujitsu sell off confirmed
FUJITSU LTD.IS PLANNING to divest its bil- lion dollar stake in air-conditioning manufac- turing unit Fujitsu General Ltd. to help streamline operations.
Fujitsu CEO, Takahito Tokita, told Bloomberg that Fujitsu wouldn’t consider a partial investment.
Fujitsu General shares are worth an estimated $1.1 billion.
“We have set certain criteria for the sale, and aim to sell 100 per cent of the 42 per cent stake. We
won’t do it half way,” Tokita told Bloomberg. The Japanese firm plans to focus on informa-
tion technology (IT).
When Fujitsu reported quarterly results
in October, the company said it was consid- ering the sale of holdings in non-core affili- ates, including Fujitsu General, battery manufacturer FDK Corporation and Shinko Electric Industries Co., which makes packaging materials for
semiconductors.

Technicians key to net zero
AUSTRALIA’S 125,000 LICENSED
climate control technicians and busi- nesses are a key part of the puzzle in achieving a zero emissions future, according to the national regulator for the industry, the Australian Refrigeration Council (ARC).
ARC chief executive officer Glenn Evans said the target for the climate control (RAC) industry should not be just net zero emissions – which implies compromise – but zero emissions outright.
“Technicians deal with direct emis- sions every day as part of their lawful responsibilities under the ARCtick licence scheme, and the quality of installations and maintenance also has a massive impact on energy efficiency and indirect emissions,” he said.
“RAC technicians have set the stand- ard for more than 15 years in the emis- sion reduction space, courtesy of the ARCtick licence scheme.
“A key part of the adoption of any new technology, and policy based around new technology, is to have appropri- ately trained technicians – they are a key piece of the Zero Emissions Future puzzle.
“The ultimate objective is not just to eliminate the climate control sector’s direct emissions but also to influence indirect emissions via energy efficiency achieved through quality installations.
“The RAC sector uses almost 25 per cent of the nation’s electricity, so it stands to reason that it is the sector where the largest savings can be made.”
