Siemens also offers KyotoCooling, a technology that is quite different from traditional data center cooling methods.The traditional method involved a constant and therefore very energy intensive need for air-conditioning that resulted in higher operational costs.
KyotoCooling however, uses a modified heat-exchange wheel technology. Warm air is fed through this heat exchange wheel, is cooled, and then led back to the cool area of the room. It is an environmentally friendly system that dramatically reduces carbon dioxide emissions and also delivers significant power and cost savings.
One of our reference projects – KPN in the Netherlands – could reduce overall power consumption by 20 to 30 percent and the power consumption for cooling could be reduced by more than 70 percent. So it is not only green, but it also saves money.
