Star Refrigeration cools University of Strathclyde

Star Refrigeration has installed an Indigochiller air-conditioning system at The University of Strathclyde.

The company designed, manufactured and installed two Indigochillers on the roof of the Curran Building, each with a 750kW cooling capacity.  The chillers cool water from 12°C to 6°C, which is then pumped to air handling units throughout the six-storey building for comfort cooling.

Rob Lamb, Star Refrigeration sales and marketing director, says: “Indigochiller stands out from the rest of the market thanks to a range of unique design features and leak-tight components.  It is manufactured to ensure maximum efficiency, long-term reliability and low life-cycle costs.  These were key considerations for the University of Strathclyde when selecting a chiller.”             

Indigochiller features the Turbocor compressor, which is said to be low maintenance by design, ensuring lifelong trouble-free running.  The oil-free compressor operates on electromagnetic bearings and uses the synthetic refrigerant R134a.

Standard features include ‘leak-free’ bellows seal valves, sealed expansion valves and welded steel pipework.  The air-cooled Indigochiller has epoxy coated condenser fins as standard to reduce the risk of corrosion damage.

With growing demand to cut refrigerant leakage to meet f-gas regulations, Star developed its Indigochiller for medium to large scale air conditioning and process cooling.  The company claims it uses only 60% of the energy required by a standard chiller operating on typical load and ambient profiles.

Available as an air-cooled or water-cooled unit, Indigochiller has capacity options ranging from 250kW to 1,650kW.  A robust PLC computerised control system allows the user to monitor refrigerant charge, running conditions and optimise efficiency.
