Abstract

In order to analyze the cold loss and cold storage performance of the pipe network cold storage system, the soil temperature field model, the cold loss and thermal resistance model of the pipe network are established, and the experimental verification is carried out by using the pipe network cold storage system of the regional energy station in Binhu New Area of Hefei. The experimental results show that the cold loss power of pipe network accounts for about 6.81% of the rcrred maxiccm cooling capacity of the whole power station, the power consumption of the cold storage strategy is 9.25% more than that of the non storage strategy, but the cost saving rate can reach 22.26%. The economic benefits can be further improved by increasing the cold storage power at night and reducing the cooling power in the daytime. With the decrease of service range of single energy station, the increase of users and the application of multi energy complementary, the energy consumption of the system will be greatly reduced.
