There are 14 external Cooling Distribution Units (CDU) as the one shown in Figure 2-4(a). These CDU units are connected to 101 rear door cooling units (Figure 2-3 b) through underfloor piping as shown in Figure 2-4(b). The maximum chilled water capacity is 65 kg/s but the actual hourly usage is approximately 30 kg/s. Figure 2-3. (a) Data server racks (b) Rear door cooling units. The Purdue University West Lafayette campus benefits from a combined heat and power system that utilizes steam not only to provide heat to facilities but also to generate electricity and the chilled water that is used to cool facilities such as data centers. Figure 2-5 shows the energy flow diagram of the current system. Chilled water at 7°C is provided to the MATH data center by 10 electric driven chillers and 3 steam driven chillers. A turbine and a generator are used to produce electricity from the high temperature and pressure steam at 435°C and 4.48 MPa, which is produced by 1 coal fired and 3 natural gas fired boilers.
