Figure 2-6. Heating load of the MATH building and cooling load of the MATH data center. 2.3. Mathematic Department - Proposed System The proposed CO2 heat pump system would replace the 13 chillers shown in Figure 2-5. The chilled water required to cool the data center is instead provided by a CO2 heat pump system. The heat rejected by the electrical equipment will be pumped to a higher temperature of approximately 62° C which can be utilized to heat the rest of the building. The energy flow diagram of the proposed system is shown in Figure 2-7. The CO2 heat pump system is designed to meet the cooling demand of the data center. The waste heat is utilized to heat the MATH building in which the data center resides. Figure 2-8 is the schematic diagram of the proposed the system. The cold water from the evaporator is used to cool the data center. The system has two compressors with intercooler. It takes advantage of single stage compression in cold winter months and two-stage compression in warm summer months. A gas cooler is used to cool the refrigerant in heat exchange with water. The heated water is then used to provide heating to the building. After passing through the gas cooler, the refrigerant passes through the air cooler. 17PDF Image | CO2 HEAT PUMPS FOR COMMERCIAL BUILDING APPLICATIONS
