In order to reduce the energy consumption of data center,a solar energy-driven combined cooling and power supply system for data center application was proposed,and the thermodynamic model and exergy analysis model for the proposed system were established.The effects of key parameters,such as solar radiation intensity,turbine inlet temperature and generator heat source inlet temperature on the system performance,have been investigated.The results show that the total energy utilization efficiency and exergy efficiency are 30.59%and 20.71%,respectively,under the design conditions.When the inlet temperature of the generator heat source is higher than 385 K,the cooling efficiency of the system slows down and reaches the maximum at 412 K.In addition,after the optimization algorithm for the performance of the system,and the total energy efficiency and net out-put work of the system are improved by 13.435%and 61.94%respectively.
