District cooling technology has developed at fast speed in Europe and the Middle East in recent years. However this technology was only in early stage of development in China. There is still much to be improved concerning relevant product classification, technical standards and specifications. As people have pressing needs for high-quality life when their living standards improve, the domestic district cooling industry is bound to develop rapidly in the next 5 to 10 years. In order to fill the niche of the potential market, HTN has made much effort to build on the technological base and carry out research and development. Practically, it provided the district cooling pipeline system to Guangzhou Higher Education Mega Center, which amounted to be the biggest project of this kind in China by far. This project has been well received by the client on account of positive social and economical effects.
