The adaptive predictive control of an energy efficient central water heating system applied in the South African commercial sector
(North-West University (South Africa), Potchefstroom Campus, 2016)Since the introduction of load shedding in the latter part of 2007, Eskom, the electrical utility of South Africa, have been forced to implement energy efficient and energy management measures to ensure the stability of ... -
The conceptual design of an integrated energy efficient ore reduction plant
(2014)This study explores ways to determine the energy efficiency of a pyrometallurgical ore reduction plant and measures to improve it. The feasibility of building a commercial plant - that is more energy efficient, has a low ... -
Developing a dynamic operational energy management strategy for energy intensive industries
(North-West University (South Africa) , Potchefstroom Campus, 2017)Fossil fuels are likely to supply most human energy needs for the 21st century. However, these fuels are exhaustible and have adverse environmental effects when combusted. To reduce the negative environmental effects, the ... -
The effect of controlling main ventilation fan inlet guide vanes for a deep level platinum mine to reduce electrical costs
(North-West University (South Africa) , Potchefstroom Campus, 2017)Because of the annual electricity increases from Eskom that are above inflation, and the mining industry that is struggling to survive due to continuous increase in operating cost, the low selling price of precious ... -
Energy efficiency opportunities in mine compressed air systems
(North-West University, 2009)Demand Side Management (DSM) is one of the most viable and sustainable short term methods to address the shortfall in electricity generation in South Africa. This is because DSM projects can be implemented relatively ... -
Energy efficiency through variable speed drive control on a cascading mine cooling system
(2014)An ever-expanding global industry focuses attention on energy supply and use. Cost-effective electrical energy production and reduced consumption pave the way for this expansion. Eskom’s demand-side management (DSM) ... -
An energy efficient mass transportation model for Gauteng
(North-West University, 2011)Public transportation in South Africa is characterized by little or no consideration for energy efficiency and use of cleaner fuels. In the case of transport planning in South African cities, no assessment of the economic ... -
Energy management for improved profitability of small manufacturing enterprises
(North-West University (South Africa) , Potchefstroom Campus, 2015)Approximately 75% of small, medium and micro enterprises (SMMEs) created in South Africa (SA) fail in the first year. This is a serious socio-economic problem as SMMEs in South Africa employ over 60% of the workforce and ... -
Expanding compressed air management through cross cut isolation
(North-West University (South Africa)., 2022)Compressed air on deep-level mines is regarded as an important source of energy for underground mining operations, as the compressed air network forms the backbone of several mining processes over a 24-hour mining cycle. ... -
A game theoretic approach to improve energy efficiency of wireless sensor nodes
(2015)Wireless sensor networks (WSNs) are becoming increasingly pervasive in a number of applications. Due to the nature of WSNs, one of their biggest constraints is limited node energy. As WSNs grow in popularity, the prevalent ...
