Eurostars Chillers Application For Shield Tunneling Machines
1.Market development of shield tunneling machine industry
The 21st century is a century of rapid technological development. The global population has exceeded 6 billion, and the shortage of land resources has increasingly become the focus of attention of all countries. The usage of underground space will be paid more attention. Our country's tunnel construction has achieved a leap-forward development in recent years. Up to 2019, 56 cities in mainland China have a total line of 6,902 kilometers under construction. Among the 6,902 kilometers of construction lines, the underground line is 5632 kilometers, accounting for 81.6%. The annual demand for chillers in this market is estimated to be 5 million dollars.
Tunnel excavation works underground, the working environment is high, about 35~42 degrees Celsius, and the air is sultry and dusty. The operating surface of the shield machine needs to maintain a temperature of about 30 degrees.
Through evaluating and calculating, the required cooling capacity is about 290KW. Recommend Eurostars water cooled integrated industrial chiller:
