SSE enrolled specialist air conditioning and refrigeration company York to provide the equipment for the facility.
York provided two YIA single effect absorption chillers, a YK centrifugal chiller and three low sound cooling towers dedicated to this task. These were installed within an 18-month period.
The two absorption chillers are capable of running on heat from generators and boilers during the summer period and utilise water as a refrigerant, so have a low electricity demand and are environmentally friendly. They also use microprocessor control logic, which enhances their performance.
The centrifugal chiller is a highly efficient compact unit that does not need an electrical substation, as it has its own motor and starter. It has been especially designed to obtain high levels of thermal transfer.
The units are all controlled by York's OptiView graphic control centre, which gives improved access to chiller operating data. SSE operators can adjust the chiller to optimise its performance, simplify its maintenance scheduling and improve reliability by pinpointing problems before they cause downtime.
The control centre automatically performs adjustments designed to correct problems before they lead to a shut down. The versatile control centre unit can also integrate with most major industrial systems. The system's small footprint helped Scottish and Southern Electric conserve vital floor space within the energy centre.
