Application Analysis of Data Centre Cooling Systems Based on Dewpoint Indirect Evaporative Cooling Towers
Under the background of"double carbon",evaporative cooling technology has become an important means to reduce the energy consumption of the data centre and meet the PUE index of the data centre,and the optimization of the cooling system of the data centre will make an important contribution to energy saving and carbon reduction in this field.This paper describes the data centre indirect evaporative cooling pre-cooling integrated architecture cooling system.The system applies dew-point type indirect evaporative cooling tower,which supplements the short board of the traditional cooling tower and achieves a water outlet temperature lower than the wet bulb temperature,significantly increasing the utilization time of the natural cooling source throughout the year;it also adopts the downward-feeding column-to-column air conditioning,and builds the end-end secondary pump into the inside of the end-end air conditioning,which reduces the power consumption of the primary pump and achieves the personalized load control on the side of the end end-end and the cooling source;and the airflow organization of the closed hot and cold channels can maximally improve the The airflow organisation of the closed hot and cold channels can maximise the utilisation rate of the air conditioning system in the server room and make the system have a highly efficient cooling effect.At the same time combined with the actual application cases,through the measurement of the annual comprehensive energy coefficient(GCOPA)of 6.64,power utilization efficiency(PUE)can be as low as 1.23 and water utilization efficiency(WUE)of 1.39 to evaluate and verify the energy saving effect of the system,the results show that the system promotes the development of evaporative cooling technology in the data centre,while also contributing to the energy saving and emission reduction for the whole data centre,and has a good reputation in the field of data centre.The results show that the system contributes to the development of data centre evaporative cooling technology,while also contributing to the energy saving and emission reduction of the whole data centre,and has great application prospects in the field of data centre.
