How to design a suitable and safe air conditioning system for tunnel shield 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 a common concern of all countries. The utilization of underground space will also be paid more attention. Country's tunnel construction has achieved leap-forward development in recent years. As of 2019, there are 56 cities in mainland China with a total line size of 6,902 kilometers. Among the 6,902 kilometers of construction lines, underground lines are 5,632 kilometers, accounting for 81.6%, and ground lines are 416 kilometers, accounting for 6%; elevated lines 853.2 Kilometers, proportion, 12.4%; The estimated demand for  water-cooled screw chiller  in this market is USD 5 million per year. At present, we have a model case and hope to achieve excellent performance in this sub-industry. H.Stars Group has invested capital in this industry since the last few years .
