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 .


water-cooled screw chiller


Below is one of H.Stars Group projects done details for reference.

The tunnel excavation works underground, the working environment temperature is high (35~42 degrees), the air is hot and dusty. The operating surface of the shield machine needs to maintain a temperature of about 30 degrees.


We send cold air, comfort and health protection for the staff.

1. It is integrated and small in size. It adopts a Integrated Water-cooled Screw Chiller. The chilled water pump and its electric control are integrated into an integrated unit in the factory to reduce the equipment placement space and installation work on site.

2. The operation is stable and reliable, and the special compressor for high temperature is adopted.

3. The condenser is designed with large temperature difference and small flow to solve the problem of insufficient cooling water flow for customers.

4. Intelligent management, microcomputer control, cloud service, remote monitoring of mobile phone APP.

5. Easy installation and maintenance. The unit has been filled with refrigerant and lubricating oil before leaving the factory. Customers only need to connect the inlet and outlet pipes and power supply to run.

6. The industrial chiller matchs the high-efficiency condenser, evaporator and brand expansion valve produced by our factory.

7. Air handler with detachable filter for easy cleaning.

Avoid Downtime, Cut Costs: Smart Maintenance for Smarter Chillers

  Screw water-cooled chillers   typically operate around 3,000 hours per year, depending on China's climate and geographical conditions. Regular and scientific maintenance is crucial to ensure long-term, reliable operation, extend the lifespan, and reduce operating costs. Maintenance and Upkeep Preventive maintenance during operation and inspection involves creating annual and monthly maintenance plans based on actual operating conditions. Shutdown Procedures In winter, clean and dry the unit. Open the drain valve to empty the  shell-and-tube heat exchanger  to avoid freezing. The shutdown sequence is: chiller off - cooling tower fan off - cooling water pump off - chilled water pump off. Special attention to anti-freezing: 1. Drain the evaporator and condenser if the unit is outdoors below 0°C during standby. 2. Interlock the water flow switch with the unit to prevent freezing when the chilled water flow switch malfunctions. 3. Ensure water in the evaporator is flowi...

What Are the Key Requirements for Flooded-Type Heat Exchangers in Air Suspension Chillers

  Air suspension chillers   are crucial in many industrial and commercial applications, and the flooded-type heat exchanger is one of the most important components of these systems. Understanding the requirements of the heat exchanger is essential to ensuring the air suspension units operate efficiently and remain stable. A flooded-type heat exchanger works by transferring heat between two fluids with different temperatures. In air suspension chillers, it helps regulate temperature, optimize energy use, and improve overall performance. For instance, it can transfer heat from high-temperature gases to low-temperature liquids, or vice versa. 1. Material Requirements 1.1 Corrosion Resistance In many industrial environments, fluids can be corrosive. For example, they may come into contact with acidic or alkaline substances. To withstand these conditions, the heat exchanger’s tubes and casing need to be made from corrosion-resistant materials, such as stainless steel. Stainless ste...

Hotels Go Green: Heat Recovery Chillers Cut Costs and Carbon Footprints

  In the operation of hotels, energy costs are a significant factor that cannot be overlooked. The advent of   heat recovery chillers   offers an efficient and energy-saving solution for hotels. ​ A heat recovery chiller, in simple terms, not only performs cooling tasks but also effectively recovers heat. For hotels, this is a highly practical feature. Traditional chillers only accomplish cooling, wasting the heat generated. However, heat recovery chillers are different; they can convert the otherwise wasted heat into usable hot water. In principle, during the cooling cycle of a chiller, the refrigerant releases heat. Heat recovery chillers use special devices to collect this heat, and through a series of heat exchange processes, they can produce hot water. This hot water can be used in various scenarios within the hotel. For example, it can supply water for guest rooms' washing and brushing, provide hot water for the hotel's restaurant kitchen, and even be used for heati...
