Case study: the effects of a variable flow energy saving strategy on a deep-mine cooling system
Du Plessis, Gideon Edgar; Liebenberg, Leon; Mathews, Edward Henry (Elsevier, 2013)Cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water to the mine as well as cooling for mine ... -
The use of variable speed drives for cost–effective energy savings in South African mine cooling systems
Du Plessis, Gideon Edgar; Liebenberg, Leon; Mathews, Edward Henry (Elsevier, 2013)An industrial energy efficiency improvement through the introduction of modern technology is an important demand-side management initiative. Cooling systems on South African mines have been identified as large electricity ... -
A variable water flow strategy for energy savings in large cooling systems
Du Plessis, Gideon Edgar (North-West University, 2013)Large cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water and cool ventilation air. Improving ... -
A versatile energy management system for large integrated cooling systems
Du Plessis, Gideon Edgar; Liebenberg, Leon; Mathews, Edward Henry; Du Plessis, Johan Nicolaas (Elsevier, 2013)Large, energy intensive cooling systems are found on deep level mines to supply chilled service water and cool ventilation air to the mine. The need exists for a simple, real-time energy management tool for large, integrated ...
