AC-powered underground mining equipment AC refers to mining machinery driven by alternating-current motors and electrical control systems, differing from DC-driven and diesel-powered counterparts.
1. Cooling performance of qualified standard models
- Working conditionsUnder open field direct sunlight, the body surface temperature can exceed 50℃. The harvester cab has poor airtightness and large heat-absorbing glass, making it harder to cool than ordinary truck cabs.
- Actual cooling effect
- Outdoor temperature 35–38℃: Turn on the maximum wind speed, the cab temperature stabilizes at 24–28℃ in about 10 minutes with comfortable cooling.
- High temperature of 40℃ at noon under direct sun: It can maintain 28–30℃, keeping the cab non-stuffy and sweat-free, fully suitable for field operation.
- Harvester HVAC provide stronger and more even cooling without direct wind blowing compared to wall-mounted split types.
2. underground mining equipment AC Key factors affecting cooling performance
- Voltage & PowerChoose 24V high-power models. 12V low-displacement units have weak cooling and cannot cool down effectively at noon.
- Dustproof & Heat DissipationThere is plenty of straw and dust in farmland. Once the condenser is blocked, the cooling capacity will be reduced by half significantly, and the cab cannot cool down for a long time.
- Cab Sealing PerformanceAir leakage from doors and windows or aging sealing strips causes cold air loss, even high-power air conditioners cannot work well.
- Installation & RefrigerantUninsulated pipelines or improper refrigerant filling amount will lead to poor cooling and unstable temperature.
3. Common unsatisfactory situations
- Only slight cool wind with temperature unable to drop for a long time: Mostly 12V low-power model, blocked condenser or refrigerant shortage.
- Cool at the beginning, then weaker cooling: Poor heat dissipation, condenser covered by dust and straw debris.
- Wind blowing but no cooling: Compressor not working or belt slipping.
