Mine Cooling and Refrigeration Fan (Underground Mining Cooling Machine)

Mine Mining Area Cooling and Refrigeration Air Unit

Introduction

Based on the design and usage experience of mining-type mine mining area cooling and refrigeration air units, this unit adopts an optimized design, can be easily installed underground in mines, is simple to operate and convenient to use, providing a comfortable environment for mining operations and effectively ensuring improved production efficiency.

For the mining industry, whether it's gold mines, iron mines, fluorite mines, copper mines, nickel mines, gem mines, mica mines, asbestos mines, tungsten-zinc mines, silicon mines, rare earth mines, or other types of mines, since ores are located within underground rock layers, mining areas are generally high-temperature environments. Using ordinary fans to send fresh air into mines for cooling is very limited and cannot effectively reduce temperatures. This is an urgent problem the industry needs to solve. Therefore, it is necessary to configure a mine mining area cooling and refrigeration air unit to locally cool the operational area. Only by reducing the temperature in the mining area to below 30℃ can workers have a suitable environment for mining operations. When selecting the unit, it is essential to consider relevant mining environmental factors. Mines contain combustible gases, and if the unit has a circuit fault, it could cause open flames and potential losses. Hence, standard commercial air coolers are not suitable for this industry and also fail to meet environmental regulations. In 2016, our company developed a mining-type mine mining area cooling and refrigeration air unit product specifically for the mining industry. After being used in Hebei iron mining areas and Shandong gold mining areas, it has proven feasible, with all indicators meeting mining requirements.

Unit Advantages

1. The unit utilizes compressor-based evaporative cooling, is water-free, has a long air delivery distance, high air volume, and adjustable temperature from 5℃ to 30℃ ± 3℃ (adjusted according to actual working conditions), ensuring uniform temperature distribution in enclosed spaces and featuring filtration functionality. The environment is 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 rises above the required level.

2. Features rapid cooling, ventilation, air exchange, dehumidification, dust prevention, and heatstroke prevention. Improves mining 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% in investment costs, require no water connection, and feature an integrated design for easy mobility. In contrast, ordinary mine cooling systems involve a host unit sending cold water to the mine entrance for heat exchange, then delivering cold air to the mining area. This method results in higher procurement and operational costs compared to our product—procurement costs are 30% higher, and operational costs are 50% higher. In terms of cooling effectiveness, ordinary mine cooling systems are also inferior to our mining-type units.

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

Working Principle

A suitable location in the mine is selected to place the mining-type mine mining area cooling and refrigeration air unit. Based on the refrigeration principle of the scroll compressor, air from the mine is drawn in, refrigerated, and used as a cold source. The cold air is then delivered to the mining operational 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 delivery, and low noise. The fan bearings use lithium-based grease, requiring no additional lubrication during long-term operation.

3. Uses an air-cooled condenser: hydrophilic aluminum foil, copper heat exchange, cross-arranged copper tubes, double-curved corrugated aluminum fins, and tube holes with secondary flanging. Mechanical tube expansion ensures tight contact between copper tubes and fins, resulting in effective heat transfer, low air resistance, and easy cleaning.

4. Features a combined sheet metal structure for easy maintenance and internal cleaning, thickened sheet metal, 6 to 8-inch large rubber wheels, and a unit structure customizable according to the user’s mine entrance dimensions.

5. Fully optimized technical parameters with all indicators meeting standards. Customizable design based on user requirements, providing products tailored to specific performance indicators.

After-Sales Service

1. Equipment produced by our company: one-year warranty, lifetime maintenance (excluding human factors and consumables).

2. Upon receiving a written equipment repair request from a customer, response and on-site repair within 36 hours for locations within Guangdong Province, and 72 hours for locations outside Guangdong Province.
