Abstract In response to the high energy and water consumption of data centers，hollow fiber membrane chillers were used to produce chilled water for the system in order to improve the air conditioning system performance and reduce water consumption.The response surface methodology （RSM） was used to design the experimental program.Air temperature，relative humidity，air flow rate，inlet water temperature and water flow rate were selected as impact factors.And a cooling system experimental bench based on fork flow hollow fiber membrane cooler was built.The data were collated and analyzed to assess the potential impact of each impact factor on the response values，including outlet water temperature，cooling efficiency，coeficient of performance （COP） and water consumption， and their magnitude. The results show that there is a significant positive correlation between inlet water temperature and outlet water temperature.And the cooling performance of the system is optimized when the inlet water temperature is In addition，increased air flow helps to increase cooling efficiency and COP，and can effectively reduce water consumption. While increasing the water flow rate can further increase COP，it can lead to an increase in outlet water temperature and an increase in water consumption. This study provides scientific basis and theoretical support for the optimal design of air conditioning cooling system in data centers.
