Abstract

China has one of the largest district heating (DH) markets in the world with total district heat sales in 2011 amounting to 2,810,220 TJ. Nevertheless, it still has great potential for further expanding its DH supply, due to rapid urbanization and the demand to improve the quality of life. However, the current DH system in China is in great need of system improvements, technology renovation, and optimization of operations and management. As one of the world’s leading countries in terms of DH supply, Denmark has state-of-the-art DH technologies and rich experience in the design and operation of DH systems. Experiences learned from the Danish DH system are useful for improving the current Chinese DH system. This article provides an overview of the technological differences between the two countries, focusing on: a) heat generation, b) the DH distribution network, c) DH network control, and d) the end consumer. The paper looks at the obvious differences between these two countries in terms of DH supply and concludes that there is significant, achievable potential for improvement regarding both energy efficiency and user comfort in the Chinese DH system, through technological advancement and implementing the operational know-how of more modern DH systems.
