摘要： 为分析管网蓄冷系统的冷损失及蓄冷性能,建立土壤温度场模型、管网冷损与热阻模型,并利用合肥滨湖新区区域能源站管网蓄冷系统进行实验验证。实验得出,管网冷损失功率约占整个能源站额定最大制冷量的6.81%,蓄冷策略供冷较非蓄冷策略供冷耗电量多9.25%,但节费率可达22.26%。可通过加大夜间低谷电价时的蓄冷功率,减少白天的制冷功率来进一步提高经济效益。随着单个能源站服务范围的减少、用户的增加及多能互补的应用,系统能耗会大幅降低。

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.

Key words: ground source heat pump, cold storage, energy consumption, economic analysis, cold loss
