Research On Energy-saving And Optimization Analysis Of Green-Data Centre

The energy consumption of the data center has increasingly become the focus of attention, because of the national advocate energy-saving emission reduction policies at present; In the meantime, data center power consumption becomes more and more not being ignored as it develops. The power consumption of data centre has its particularity compared to other building energy consumption:various types of energy consuming equipment, highly specialized, research on energy saving of it is comprehensive system engineering. Research status and development trends at home and abroad are summarized, on the principle of combining theory with practice, based on actual measurement data room parameters and through the software airpak to room temperature and velocity field to make simulation, and then put forward some energy saving measures, That established a certain foundation for the construction of Green-data centre.In the actual measurement data center we can use the self temperature meter instrument to test temperature field, and use of digital anemometer in the underground the outlet and the inlet of ceiling test wind speed. Parameters of the wind speed, air volume, flow, refrigerating capacity, chilled water flow etc of the refrigeration unit in refrigeration room about Data center have been tested. According to the measured temperature of actual measurement data room of the values and the measured wind speed value, combined with various specifications and standards within the industry, we analyzed the problems existing in the measured data room, also the analysis of reasons lead to the problem of existence. By using the simulation software has been, test data of room temperature field and velocity field were simulated and optimized, So that we can research the temperature field and velocity field of the optimization scheme. Through the contrast before and after optimization parameters of the Coefficient of refrigeration refrigeration room of the refrigeration unit,the opening degree of each unit. We compare and analysis of energy saving indicators before and after optimization, for example, energy consumption etc.Through the comparative analysis of the pros and cons on the air supply and air supply mode, and the optimization of the arrangement of server location, it reached this conclusion that the green data center need to send the wind of air conditioning form. The airflow gradient inside the cabinet meets the requirements for energy saving, increasing the cooling unit so that the whole of air temperature and air flow rate can play a certain role in the control room, and to make the data of low PUE value. In the cold area in winter outdoor air temperature is low, Fresh air through certain processing can be applied to the refrigeration unit, Therefore, to reduce the temperature treatment, and then analyzes the refrigerating capacity savings and maximum reduced energy consumption. Evaporative cooling water by using transition season, the results of reducing energy consumption, time and area analysis can be applied to that energy saving measures. Combination of indicators at home and abroad about data center at each index and retain certain redundancy, by taking the refrigeration coefficient, energy consumption than other energy saving index, the paper analyzes the energy saving measures of energy saving.
