Concept of District Energy
District heating, district cooling, district power supply and the energy system and comprehensive integration that solve the energy demand in a district are collectively referred to as district energy. The district can be an administrative division or natural city and urban area, or a residential quarter (building complex), or a development area and park specially designated by someone.
The district energy system is one or several combinations of heating system, cooling system, hot water supply system, steam supply system and power supply system that aim at providing system solutions to full-life-cycle energy demand in urban low carbon ecology and industrial development. It makes use of the energy resource endowment in the district according to local conditions and makes organic matching and integration in combination with energy demand, so as to accomplish more with less energy and realize high energy efficiency and the sustainable development of district energy environment.
In a word, district energy refers to the process that all energy used for production and living throughout the development history of human beings is used in a scientific, rational, comprehensive and integrated manner in a specific district and undergoes energy production, conversion, supply, distribution, use and emission completely.
Implication of District Energy
Implication: high energy efficiency, low emission; do more with less energy, emission minimization.
The high energy efficiency throughout the process from secondary production, distribution, use and monitoring to emission of energy helps better dig into resource endowment stock. Also, the integrated implementation from top-level design, planning, design, investment, construction to operation and maintenance achieves full-process energy conservation from the source, process, stage and details.
Key points: Analysis of energy resource endowment according to local conditions, simulation of local energy demand; full-process control and implementation, and achieve consistent taste, parallel temperature, ladder-form utilization, integrated complementation, multiple integration.
Scope: Whole process and whole industry chain
Whole process: Energy production, conversion, supply, distribution, use and emission.
Whole industry chain: Planning, feasibility study, design, construction, management, operation, service, course setting and talent cultivation.
User: Energy for industrial, architectural and transportation use
