Abstract:

In this present world order of growing information, communication and technological advancement, it is primordial that climate change adaptation and mitigation efforts seeks to make people resilient to inevitable climate inconsistency through the exploitation and development of renewable energy sources. Though climate impacts are global, the population most at risk is predominantly from developing countries, particularly poor communities who have experienced multi-layered threats from floods, droughts and energy supply, just to mention a few. This explains why sustainable development is at the

Abstract:

Today, thermosyphon solar water heaters are the most popular type of solar water heaters for providing households with the required hot water for domestic purposes. However, sizing and designing these systems is still based on experience or on trial and errors methods, which are based more on intuition rather than scientific methods. The present study is aimed at addressing this problem (sizing thermosyphon systems) through the development of a design tool that can be used by engineers and manufacturers to arrive at optimised systems designed according to the weather and operating conditions o

A detailed analysis of the heat transfers and fluid flows within a direct thermosyphonic solar-energy water-heater has been undertaken. The collector energy equations when cast in a two-dimensional form enabled heat transfer and thermal capacitance effects to be simulated accurately at the small flow rates encountered commonly in such systems. An investigation of thermocline relaxation processes within the store indicated negligible mixing at the store inlet over a wide range of Richardsons numbers (43,608 < Ri < 729,016).

In a period of rapidly growing deployment of sustainable energy sources the exploitation of solar energy systems is imperative. Colder climates like those experienced in Scotland show a good potential in addressing the thermal energy requirement of buildings; particularly for hot water derived from solar energy. The result of many years of global research on solar water heating systems has outlined the promising approach of integrated collector storage solar water heaters (ICS-SWH) in cold climates. This calls for a need to estimate the potential of ICS-SWH for the Scottish climate. This resea

The utility of a solar thermal energy system increases if the hot temperature source is available when it is needed most. This is realized by the thermal storage of the solar energy. Thermal storage gives greater versatility to a solar energy system by decoupling the heat source from the heat sink. A large quantity of energy may be stored during the melting process in a phase change material (PCM) within a small temperature range. This molten PC

Proprietary evacuated tube solar water heaters (ETSWH) have superior thennal perfonnance in Northern Maritime climates compared with proprietary flat plate solar water heaters (FPSWHs). ETSWHs with heat pipe absorbers are especially suited for use in Northern Maritime climates due to their freeze tolerance and self-regulating heat transfer characteristics and ability to act as thennal diodes. Typically delivering 5-15% more thermal energy per annum, than FPSWHs, this is, however, achieved with higher capital costs.

Abstract:

Includes abstract.<br>Includes bibliographical references (leaves 58-63).<br>Solar energy is abundantly available in South Africa, but it is a highly under-utilised resource. One way of efficiently using the resource is solar water heating (swh), a natural process whereby hot water for domestic and/or industrial use is heated by the sun. In 2009, a national swh strategy was drafted by the Department of Energy, which specifies a target to install 1 million heaters in households by 2015. Provincial and local governments have also developed their own swh strategies and the roll out of swhs has st

Abstract:

Includes abstract.<br>Includes bibliographical references.<br>This paper reviews how incentive mechanisms impact solar water heater (SWH) technology adoption under both monthly payment scheme (MPS) and non-monthly payment scheme (non-MPS) conditions. The key research problem is to try understand why consumers1 have not installed SWHs under non-MPS conditions and whether a MPS can generate better installation rates. SWHs generate clean energy by using the heat of the sun instead of electricity to heat household water. On average, SWHs displace 30 % of household electricity usage, decreasing bot

Thesis (MPhil)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: South Africa faces an energy crisis which presents itself in two forms; electricity generation dominated by coal fired power stations and current electricity supply capacity being unable to meet growth in demand. South Africa urgently requires new generation capacity: however, power stations take time to plan, construct and commission, meaning that South Africa has to consider other options to meet electricity demand. This necessitates quick and innovative ways of meeting future demand. Energy efficiency has been identified a

Thesis (MPhil)--Stellenbosch University, 2010.<br>ENGLISH ABSTRACT: Low-income households in the Western Cape primarily use small electrical kettles to heat water for bathing and cleaning. This energy usage pattern is problematic in that; • It is based on unsustainable energy sources that cause environmental degradation, • Electricity is becoming more expensive in South Africa which strains the limited income of poorer households and • The national utility, Eskom, is struggling to meet the demand for electricity. If energy-intensive development paths are followed these problems will esca

Abstract:

The ICSSWH (Integrated Collector Storage Solar Water Heater), apart from being the oldest is also the most economical means of solar water heating. The effect of modifications in the collector geometry has frequently appeared in the literature, and over the time, has resulted in different designs. These designs differ mainly on the site of installation as well as the target application. A novel design created by Professor T Muneer at Napier University, utilizes fins inside the storage tank to improve the heat transfer. The reported field tests of the fin type ICSSWH have indicated a 10 % impro
