Evaluation Of A Multi Objective Design Optimization Strategy For Geothermal Heat Pump

As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.

This project is planning to install 2×300MW units, The configuration of unit is Pulverized coal fired boiler with condensing steam type turbine, and Limestone-gypsum wet Flue Gas Desulphurization system adopted.

The class project for Sustainable Energy is to design a stand-alone power system for a single-family house. The stand-alone power system can either be a photovoltaic (PV) or a fuel cell combined heat and power (CHP) unit. Without connecting to the power grid either of these units will have to supply the 2,500 square foot home with both heat and electricity. In order to properly select the size of the system needed; numerous parameters need to be considered and evaluated. With these values it is then possible to determine

In today's modern industrial society vast amounts of energy are needed to make living more comfortable, productive and enjoyable. The increase in energy consumption not only caused a global spike in energy costs, but also negatively impacted our environment. Climate change, the threat of an unsecured energy supply and rising energy costs have emphasized the need for improved energy efficiency. Efficient energy use is essential as it enables financial savings, preserves fossil fuel resources, and reduces air pollution. Reducing energy consumption and lowering Greenhouse gas emissions are the two most important reasons to improve energy efficiency. Pollution is a major disadvantage of fossil fuels causing air pollution, water pollution, damage to public health, wildlife and habitat loss, and global warming emissions. However renewable energy sources such as wind, solar, geothermal, biomass, and hydropower provides sustainable energy services, of which solar energy is one of the cleanest, abundant and most sustainable ways to generate electricity.

As a homeowner, you're grateful for a roof over your head and the warmth it provides. You're also grateful for your HVAC system. Although this probably sounds weird, it's your HVAC system that works hard and efficiently all year-long making sure you and your family feel comfortable. This is especially true when the temperatures outside are “extreme.”

Over the past decade, energy has brought social, economic and environmental advantages and played a major role in the urbanisation and industrial revolution. However, after the uncontrollably frequent use of these energy sources, depletion of these energy sources also became a major concern which brings about its own economic, social and environmental disadvantages. Of a particular concern is the availability of these energy sources which affects both industry and the lives of the consumers.

Energy is an integral part of our daily lives. While organisms get energy to move from food, non-living appliances such as phones, lights, cars etc. get their energy from other renewable or non-renewable sources. The majority of energy consumed comes from non-renewable energy sources: fossil fuels (oil, gas and coal) and nuclear energy. In the past few decades, the issue of a potential “energy crisis” has arisen. Since people nowadays use such large amounts of fossil fuels, they will run out in the near future. Out of the three fossil fuels, oil and gas are the most widely used. It is predicted that, without taking into account the new reserves that could become accessible with the advancement of technology, oil and gas

Energy is a fundamental factor to the existence of humans on this planet; without it, modern society would be unsustainable. Consequently, the sourcing and production of energy is a critical global issue that must be addressed. Currently, the most common energy sources are fossil fuels: oil, coal, and natural gas. The consumption of fossil fuels is not sustainable in the long run as the resources are not infinite, and as energy consumption increases, the earth’s natural resources (fossil fuels) are depleted. The belief that conventional energy sources are unsustainable prompted the development and use of renewable energy sources such as solar, wind, and hydroelectric. The sustainability of energy is such a demanding issue that Germany

With the help of new technologies and studies, these old energy sources are becoming more popular as time goes on. The growth of sustainable energy, which includes Solar, Wind, Biomass, Biogas, and Geothermal, has become a major factor in the business of supplying

This report shows the differences and the similarities between Dundee University’s heat energy systems and those that are employed by Hillcrest Housing Association. The main technologies used in the university are gas fired engines, whereas the Hillcrest building which has a biomass boiler. As far as models of ownership are concerned, the University has established a wholly owned operating company DUUSCo to undertake the Project. While, although owned by Hillcrest the biomass system is operated and maintained under a 10-year agreement by Angus Biofuels who sell the energy to Hillcrest. Finally, comparing the risks associated with security of energy delivery we can say that they are similar. Even if the two heating systems are different, both of them had the same goal, reducing the energy used and achieve low energy consumption. And move a step closer to sustainable and zero carbon buildings. An explanation of “zero-carbon” meaning is given.

Energy efficiency and renewable energy sources are some of the important features that must be integrated to existing and future buildings in order to reduce their energy consumption and emissions footprint. Energy efficient advances in lighting, Heating, Ventilation and Air Conditioning Systems (HVAC) constitutes some of the opportunities for improvement. Australia owns an important access to renewable energy sources through the entire extension of the country. Solar power and water heating, wind power and geothermal power are some of the technologies been implemented to reduce energy consumption and decouple from conventional sources.

The needs for alternative energy are present today with China and India growing in population and increasing their oil consumption. In addition, the demand and competition for oil in a near future will eventually be too great for the supply; indeed, our lifestyles are currently based on inefficient energy devices. This includes automobiles and electric appliances that

Climate change is an inevitable and evident problem that has been debated on for quite a few decades. The role of energy usage towards increasing or decreasing the rate of change in climate and causing global warming is a very controversial topic in this world which exponential growth of population and economy. The amount of energy used and the type of energy used is also one of the key factors that contribute to this debate. Fossil fuels such as coal, natural gas and oils have been dominating the energy usage in the world and without doubt they create these unavoidable externalities such as pollution. The purpose of this paper is to

ABSTRACT: There is a rising interest on the process of passive design due to the shortage of resources. Earth tube, as known as earth-air-heat exchangers (EAHE), is one of the passive design approach for cooling and heating. Nowadays a plenty of study have been carried out to assess the performance of earth tube. This literature review focus on the aspects, which are pipe material, pipe length and soil condition influence the performance of earth tube. Moreover, to investigate how the cooling and heating potential could be influence. Throughout the literature, the soil

An alternative is to use air as the cooling medium but their performance drops in hot weather conditions. Maximization of overall efficiency is as vital as the cost and availability of water. Therefore there is a need to integrate the technologies of air cooled and water cooled condensers. This paper will focus on parallel condensing where steam from the turbine is ducted in parallel to both air cooled and water cooled condensers. To optimize the parallel condensing capacities of air cooled and water cooled condensers considering parameters such as ambient temperature, pressure, availability of water, fan power, pumping costs.
