Tianjin Binhai High-Tech Industrial Development Zone was established in 1988, approved by the State Council as the first batch of national high-tech zones in 1991, and approved as a national demonstration zone of independent innovation in 2014. The zone has gathered a number of strategic emerging industries represented by China Science and Technology Shuguang, Feiteng, Kirin and Qihoo 360, and has attracted a number of leading enterprises such as Cloud Account, Ziguang Cloud, Today’s Headlines, Tencent, Tuniu and 58 Tongcheng, etc. It has gathered a number of high-end research institutes such as the Fifth Institute of Aerospace, the Eleventh Institute of Aerospace, the Eighteenth Institute of CEC, the Advanced Institute of China Science and Technology, and the Binhai Research Institute of Zhejiang University, etc., making the Marine High-Tech Zone the city’s most innovative resource It has become the area with the most abundant innovation resources, the most independent intellectual property rights and the most potential for economic growth.

Project programme

The original heat exchange system of the Ocean Hi-tech Zone Management Committee Building was seriously aged and without energy metering and automatic control system, relying only on manual operation, with serious energy wastage. In order to meet the building’s winter heating demand and improve energy utilisation, the technical team of Hengtong adopted the idea of unattended heat exchanger unit with independent intellectual property rights and adopted Armstrong technology to achieve zero overflow (circulation flow), zero overload (heat production), zero distance (remote control), automatic, digital and intelligent operation of the system.
