Tunnel boring machine (TBM) matching refrigeration units (air coolers)

Introduction

Currently, more and more subway construction projects are using tunnel boring machines (TBMs). As TBMs generate a large amount of heat during tunneling operations, combined with poor ventilation conditions inside the tunnel, high temperature and humidity in the tunnel, and other factors, the generated heat cannot be cooled or dissipated in time, resulting in harsh working conditions inside the tunnel and potential safety hazards. Therefore, it is essential to take measures to reduce the temperature inside the tunnel and improve working conditions.

Tunnel boring machine (TBM) matching refrigeration units (air coolers) product features

Baochiyuan air coolers are widely used in production workshop workstations, aircraft maintenance, open-air catering, bridge steel box girder welding, hull painting, sandblasting, docks, shipyards, decks, segments, and other high-temperature workplaces for ventilation, temperature reduction, and improving the working environment. They are also suitable for tunnels, mine operations, and other places that require localized cooling.

Unit features:

1. Casing: Made of high-strength steel plate with spray coating, using outdoor paint, fully rainproof, with the most advanced patented technology and high-precision processing to ensure no rusting in acidic or alkaline gas environments. Equipped with built-in cup-type universal casters.

2. Compressor: Uses internationally renowned brands such as Japan's Panasonic and America's Copeland series compressors, providing high cooling capacity and quiet operation.

3. Condenser: Air-cooled fin condenser uses clean aluminum foil to enhance corrosion resistance, with excellent heat dissipation, easy cleaning and maintenance, and convenient installation.

4. Evaporator: Fin evaporator uses clean aluminum foil to enhance corrosion resistance, with excellent heat dissipation, easy cleaning and maintenance, and convenient installation.

5. Air blower: Uses domestic renowned brands such as Jiuzhou and Dongqin fans, with high air pressure and airflow, durable and long-lasting.

6. Cooling fan: The entire series uses Dunli and Maer low-noise external rotor fans, with high airflow, long lifespan, and excellent heat dissipation.

7. Refrigerant throttle valve: The entire series uses Danfoss and Emerson expansion valves.

8. Taiwan's renowned brand Bangpu microcomputer control, with built-in comprehensive intelligent monitoring and protection, including motor temperature control, phase sequence monitoring, manual reset lock, oil temperature monitoring, and precise temperature control within ±2°C.

9. All electrical components use French Schneider or LG brands, ensuring high efficiency, environmental protection, safety, long lifespan, and resistance to aging. Internally integrated with multiple protection and processing functions such as water cutoff, low temperature, high/low pressure, antifreeze, phase loss, reverse phase, delayed start, overload, motor overheating, oil pressure difference, etc.

10. Refrigerant standards: Uses stable and high-strength R22. Environmentally friendly refrigerants such as R407C, R410A, R134A, R404A are also available.

11. Baochiyuan air cooler series - workstation air cooler outlet temperature adjustable from 0-25°C.
