基于暖通专业视角的区域能源系统思考——概念、规划、设计

Thinking of district energy system based on HVAC professional perspective——Concept,planning and design

就区域能源系统的概念理解、规划要点、能源站设计,以暖通工程师的视角,结合项目认识与实践对存在的问题进行了梳理与分析,主要观点是:1)区域能源并非具体的能源形式,而是基于终端需求与节能减排目标的各种形式能源系统的集成或整合;2)区域能源是规划概念,是以提高区域能效、降低区域能耗为目的的能源系统布局、技术路线与管理模式;3)区域能源规划应以终端需求为出发点,抛弃传统"大能源"供应侧思维,代之以需求侧思维;4)不能简单地将建设集中能源站视为区域能源规划的目的;5)区域能源系统设计应特别重视对终端负荷的研究,因为它直接关系能源系统配置、设备选型、节能与减排量计算,以及经济性;6)集中能源站设计应采用性能化方法,并给出了7项设计要点。

Aiming at district energy system's concept understanding,main planning points and energy station design,straightens out and analyses the problems existing in cognition and implementation from the perspective of HVAC engineers.The main points are:1.District energy is not a specific form of energy, but the integration of various forms of energy systems based on terminal demand,energy saving and emission reduction objectives;2.District energy is a planning concept,layout,technology roadmap and management of energy aiming at improving district energy efficiency and reducing energy consumption;3. District energy planning should be based on the terminal demand,and substitute the demand side thinking for the traditional thinking of comprehensive energy supply;4.Construction of centralized energy stations cannot be simply regarded as the ultimate goal of district energy planning;5.Special attention should be paid to the study of terminal load in planning district energy system,which is directly related to energy system configuration,equipment selection,energy saving and carbon emission calculation,and economy;6. Designs of centralized energy station should adopt the performance-based method,also 7 key points of design should be pay more attention to.
