(Gawkwire) – A world leader in cooling and heating system innovation, Star replaced an existing R22 refrigeration plant with a highly energy efficient, low maintenance solution. Star has provided the banking client with a state-of-the-art data centre cooling system designed for a low carbon, cost saving operation.

Operating as a data centre since 1990 in a confidential location, the building features two main data halls each with independant power and cooling infrastructure. Earlier this year IT and computer server systems in one of the data halls were being replaced as part of a major refurbishment programme.

The existing plant had a total cooling capacity of 2,700kW and operated on R22, an ozone-depleting HCFC refrigerant currently being phased out by EU regulations.

The new cooling system features four 1,100kW chillers operating on synthetic refrigerant R134a.

The innovative design incorporates revolutionary oil-free Turbocor compressors, with variable speed drives and high efficiency at full and part load. The chillers also feature an air-cooled refrigerant circuit configured for thermosyphon operation to provide “free cooling” when possible.

Star Refrigeration’s Director of Sales – Process, Alan Walkinshaw, says: “Power consumption in data centre’s has quadrupled by some estimates over the last decade. Operators are increasingly looking to reduce energy usage by IT and associated building support systems such as cooling.”
