Mine Cooling Air Conditioner (Underground Mining Cooling Machine)

Mine Mining Area Cooling Air-Cooled Unit

Introduction

Based on the design and usage experience of mining-type mine mining area cooling air-cooled units, this unit adopts an optimized design for easy installation in mines, simple operation, and convenient use. It provides a comfortable environment for underground mining operations, effectively enhancing production efficiency.

For the mining industry, whether it's gold, iron, fluorite, copper, nickel, gemstone, mica, asbestos, tungsten-zinc, silicon, rare earth, or other mines, since ores are located in underground rock layers, mining areas are generally high-temperature environments. Using ordinary fans to supply fresh air into mines for cooling is very limited and cannot effectively reduce temperatures, which is an urgent issue the industry needs to solve. Therefore, it is necessary to configure a mine mining area cooling air-cooled unit for localized cooling of the work area. Only by reducing the temperature in the mining area to below 30°C can workers have a suitable environment for mining operations. When selecting a unit, it is essential to consider mining environmental factors, such as the presence of combustible gases in mines. If the unit has a circuit fault, it could cause open flames and potential losses. Hence, standard air coolers commonly used are not suitable for this industry and cannot pass environmental inspections by relevant authorities. In 2016, our company developed a mining-type mine mining area cooling air-cooled unit product, which has proven feasible after use in Hebei iron mining areas and Shandong gold mining areas, meeting all mining requirements.

Unit Advantages

1. The unit utilizes compressor-based evaporative cooling, is water-free, has a long air supply distance, high air volume, and adjustable temperature from 5°C to 30°C ± 3°C (adjusted based on actual working conditions), ensuring uniform temperature distribution in enclosed spaces and featuring filtration functionality. The environment remains fresh with high oxygen levels and clean air. During normal operation, when the reduced temperature meets the required space temperature, the unit automatically shuts off and restarts only when the temperature exceeds the required level.

2. Features rapid cooling, ventilation, air exchange, dehumidification, dust prevention, and heatstroke prevention. Improves mining work efficiency, saves electricity, reduces costs, enables quick installation, and facilitates maintenance.

3. Compared to standard water-cooled units: Our company's mining-type units can save 30% to 50% of investment costs, require no water connection, and feature an integrated design for easy mobility. In contrast, ordinary mine cooling units involve a host machine sending cold water to the mine entrance for heat exchange, then supplying cold air to the mining work area. This approach results in higher procurement and operational costs compared to our products—procurement costs are 30% higher, and operational costs are 50% higher. In terms of cooling effectiveness, ordinary mine cooling units are also inferior to our mining-type units.

4. In terms of refrigeration: Ninewells brand mining-type mine mining area cooling air-cooled units offer fast cooling. Within 30 minutes of startup, the mining work area shows noticeable cooling effects.

Working Principle

A suitable location in the mine is selected to place the mining-type mine mining area cooling air-cooled unit. Based on the refrigeration principle of the scroll compressor, air from the mine is extracted, cooled, and used as a cold source. The cold air is then delivered to the mining work area via a blower.

Unit Features:

1. Scientifically designed, meticulously manufactured, with an attractive appearance, excellent performance, and reliable quality.

2. Equipped with a centrifugal fan for high air volume, long-distance air supply, and low noise. The fan bearings use lithium-based grease, requiring no additional lubrication during long-term operation.

3. Utilizes an air-cooled condenser: hydrophilic aluminum fins, copper heat exchange, cross-arranged copper tubes, double-curved corrugated aluminum fins, and double-flanged tube holes. Mechanical tube expansion ensures tight contact between copper tubes and fins, providing excellent heat transfer, low air resistance, and easy cleaning.

4. Features a combined sheet metal structure for easy maintenance and internal cleaning. Includes thickened sheet metal and 6 to 8-inch large rubber wheels. The unit structure can be customized based on the user’s mine entrance dimensions.

5. Fully optimized technical parameters meet all standards. Customized designs and products with tailored performance indicators are available based on user requirements.

After-Sales Service

1. Equipment produced by our company comes with a one-year warranty and lifelong maintenance (excluding human factors and wear parts).

2. Upon receiving a written equipment repair notice from the customer, we respond within 36 hours for repairs within Guangdong Province and 72 hours for repairs outside Guangdong Province.
