In response to the problems of high energy consumption of existing air conditioning systems and unstable temperature fluctuations of cold air produced by evaporative cooling air conditioning technology due to the outdoor environment,a seasonal ice storage and evaporative cooling coupled air conditioning system is proposed to store the cold in winter for use in summer and assist evaporative cooling technology to produce cold air.And a data center in Yulin city is taken as an example,and the system is modeled based on TRNSYS simulation software to analyze the cold storage throughout the year and verify its feasibility of cold capture and storage in Yulin area.Its annual operation energy consumption was simulated,and it was concluded that the data center PUE value was stable at about 1.1 throughout the year.The energy consumption of the coupled seasonal ice storage and evaporative cooling air conditioning system was compared with that of the mechanical cooling and evaporative cooling plus mechanical cooling air conditioning systems with the same cooling capacity,and the PUE was reduced by 0.66 and 0.13,respectively.
