Taking an industrial park in Zhongshan as an example,design and estimate the equipment and initial investment of three types of cold source systems:conventional system,water storage system,and ice storage system.Two operating modes and control strategies of cold storage systems were proposed,and based on this,the electricity bills and static payback period of investment for the three cold source systems were compared.When using a cold storage system as the cold source in this project,the initial investment of the water storage sys-tem increased by 11.2 million yuan compared to the conventional system,resulting in an annual operating cost savings of 5.74 million yuan and a static payback period of 1.95 years;The initial investment of the ice storage system increased by 11.6 million yuan compared to the conventional system,resulting in an annual operating cost savings of 5.19 million yuan and a static payback period of 2.80 years.From the perspective of later operating costs,the cold storage system is superior to conventional cold source systems,and the water storage system has a shorter recovery period,saving more electricity bills.
