Design and optimisation of a solar thermal powered Aqua-Ammonia diffusion-absorption heat pump cycle under seasonal variance for residential use
(North-West University (South Africa)., 2021)The diffusion-absorption refrigerator was patented by Von Platen and Munters (1926). The conventionally low coefficient of performance and the high driving temperature have been the focus of most research since its ... -
The development of a model for the absorber component of an aqua-ammonia absorption heat pump
(North-West University (South Africa) , Potchefstroom Campus, 2016)In recent years, South Africa as a country has increasingly faced challenges in regards to electricity provision. Modern society is highly dependent on refrigeration technology in order to refrigerate food, not only ... -
An improved baseline model for a mine surface cooling plant DSM project
(North-West University (South Africa) , Potchefstroom Campus, 2017)Several challenges exist for the successful implementation of energy cost reduction projects on industrial systems. Due to the potential large financial impact of these projects, the process of determining and reporting ... -
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
(2014)South Africa’s electricity supply is under pressure. Mining is one of South Africa’s largest electricity consumers with electricity-intensive services such as compressed air, cooling, ventilation, etc. More than 40% of ... -
Modelling and design of an efficient low temperature closed cycle dehydration system
(North-West University (South Africa), 2021)Research indicates that there is a growing interest for the preservation of foods due to an increasing demand as a result of a growing global population. Preservation of food commodities by means of dehydration methods and ... -
Optimising deep-level mine refrigeration control for sustainable cost savings
(North-West University (South Africa) , Potchefstroom Campus, 2017)Declined productivity and increased operational costs have seen South African deep-level gold mines become marginal operations during the past few years. The price of electricity is one of the major contributors to an ...
