碩士 === 國立勤益科技大學 === 冷凍空調系 === 98 === The information room (IT Equipment) are equipped with large heat dissipation devices, Its energy consumption per unit area is very "significant." To take away the heat generated by IT equipment, IT room air conditioning to cool the room must be set and maintain the space for the working environment. Weather these air-conditioning operation is appropriate, the energy consumption must be obedient to existing laws and regulations, which affect the overall cost of operation directly. In this study, a domestic semiconductor plants information room air conditioning system energy consumption analysis is conducted. First, relation between supply air rate and rack fan volume flow rate affect temperature field and velocity around single rack is analyzed by STAR-CD computational fluid dynamics software package. So the position and outlet type can be improved and overall operating efficiency of air conditioning system is found out and implement. Second, the heater and humidifier operation point setting within air-conditioning (CRAC) is considered. It is found out when operation temperature and humidity are adjusted higher can reduce substantially air-conditioning energy consumption. After this two above-mentioned methods are implemented. Overall air-conditioning system energy saving is 30.76%. Its PUE(Power Usage Effectiveness) value decrease from 1.908 to 1.721.
