Data-Centre cooling saves energy and creates revenue
SemperTec's Delta-T cooling solution for data centres is based on installing cooling units in the rows of racks, rather than CRAC (computer-room air-conditioning) units around the perimeter.
By localising cooling in this way, the number of IT racks in a room can be increased by 16%. An example put forward by SemperTec is 352 racks being increased to 408, with the potential revenue from those 56 extra racks being over £1 million a year. And there's an electricity cost saving of over £77 000 a year compared with CRAC units.
