Sino Finnish pilot project in Changyuan

Dunan Energy Saving Technology Co., Ltd. (the company) hired Planora Oy (consultant) in the company’s Changyuan district heating pilot project in 2017 to participate in the company’s Changyuan district Sino-Finnish heating pilot project and created expert database for the pilot area, and completed a grid hydraulic calculation to find the functional improvement of the existing district heating system to achieve the key performance indicators of the Finnish Energy Model (FEM) of the future Changyuan heating network.

盾安节能技术有限公司（公司）于2017年在公司的长垣地区供热试点项目中聘请普兰诺拉Oy（顾问），参与公司长垣地区中芬供热试点项目，为试点地区创建了专家数据库，并完成了一次网水力计算，以查找现有区域供热系统的功能改进，以达到未来长垣供热网络芬兰能源模型（FEM）的关键绩效指标。

After 1 phase and 2 phase of the project, Both parties agree and recognize the following results achieved in the pilot project：

  • In the pilot area, all pipe sizes are reduced by one nominal DN size, saving approximately 20% of pipeline investment
  • Due to the reduced pipe size, the network heat loss is reduced by about 10%
  • In the Longshouyuan demonstration community, the thermal index (120 days) was reduced from 36 GJ/m2 to 0.31 GJ/m2, an increase of 14%
  • Optimize the future heating capacity demand from 174 MW to 116 MW in 2030, saving 30% of heat capacity and 20% of investment
  • Find the bottleneck of the current network
  • Suggestions on improving the existing district heating system
  • Supplement the original short-term and long-term development plan
  • Create a digital network model for future FEM cloud services

在项目的第一阶段和第二阶段之后，双方都同意并认可在试点项目取得的以下成果：

  • 在试点区域，所有管道尺寸均减少了一个标称DN尺寸，节省了约20％的管道投资
  • 由于管道尺寸减小，网络热损失减少了约10％
  • 在龙首苑示范小区中，热指标（120天）从36 GJ / m2降低到0.31 GJ / m2，提高了14％
  • 将2030年未来的供暖能力需求从174 MW优化到116 MW，将30％的热容量节省下来，将20％的投资节省下来
  • 查找当前网络的瓶颈
  • 关于改善现有区域供热系统的建议
  • 补充原始的短期和长期发展计划
  • 为未来的FEM云服务创建数字网络模型
