· Spot coolers come in a range of capacities. They are rated based on their BTU. You might see spot coolers listed as being between 1 ton and 5 tons. They don’t weigh that much, though. The unit “ton” refers to the BTU, which is the heat load it is rated for. A 1 ton spot cooler, or 12,000 BTU, will sufficiently cool up to two people in

Ice is colder than water or air conditioning and has a much higher potential for mass cooling (latent melting heat of 333 kJ/kg). It descends through the PVC pipe at a higher speed (2 km in 90 seconds) and still reaches the different levels of the mine at 0°C, with minimal heat loss. These unique properties make ice an attractive and energy

· That will help you determine the cooling capacity (measured in BTUs) you need. A small spot cooler can cool a space up to 250 square feet, while a larger one can cool up to 1,000 square feet. If you only need to cool a small space, a personal spot cooler might be all you need. These are perfect for cooling down single rooms or small areas.

· Ice systems and spot coolers The cooling capacity of 1.0 l/s of chilled water supplied underground is 100 to 120 kWR. On mines where large amounts of refrigeration are required underground at depths greater than 2,500 m, the costs of circulating the chilled water can justify replacing it with ice.

· Ice is pure cooling energy. Thanks to its unique latent heat of fusion, (capacity to absorb heat as it melts), a given mass of ice provides much more cooling than the same water quantity. Whilst one litre of water absorbs 4kj/kg, 1 kg of ice absorbs 333kj as it melts (from -0°C to +0°C). Introducing ice in the mine shaft, thus enables to
