Abstract:

This paper studied the intelligent control system of district heating based on the fixed structure phase change heat storage module, and described the fixed structure phase change heat storage module and heating system. Combined with the change rule of load coefficient of winter heating with outdoor environment temperature, the intelligent control system of district heating and its connotation were proposed. Combined with the demonstration project of urban district heating, the intelligent heating system was compared with the traditional two operation modes, and the operation cost of heating equipment was reduced by 24% and 32% respectively. Based on the fixed structure phase change heat storage module heating system, the operation cost was reduced significantly after using intelligent control system because of the use of low valley power or renewable energy. Compared with the traditional two operation modes, the intelligent heating system reduced the operation cost of heating equipment by 70% and 73.3%, respectively. Therefore, based on the fixed structure phase change heat storage module district heating, the use of intelligent heating system was of great significance to reduce operating costs.

Key words: phase change heat storage module with shaped structure, district heating system, intelligent control system, operating cost analysis

摘要：

研究了基于定型结构相变储热模块小区供热的智慧控制系统，对定型结构相变储热模块及供热系统进行了描述。结合冬季供热的负荷系数随室外环境温度的变化规律，提出小区供热的智慧控制系统及其内涵。结合城市小区供热的示范工程，智慧供热系统与传统二种操作模式进行对比，分别降低供热设备运行费用24%、32%。基于定型结构相变储热模块供热系统，因为使用低谷电或可再生能源用电，使用智慧控制系统后，运行费用降低明显。智慧供热系统与传统两种操作模式进行对比，分别降低供热设备运行费用70%、73.3%。因此，基于定型结构相变储热模块小区供热，采用智慧供热系统对于运行费用降低具有非常重要的意义。
