Solar Powered Refrigerator Refrigertion Systems That Use Environment Friendly Refrigerants

Both water and homes have been heated by passive solar energy since 1882. Passive solar energy technology can best be described as thermal windows and orientation of buildings to receive the maximum amount of sunlight during the course of a day. Active heating, which utilizes solar panels, is largely a development of the 20th century. Although heating homes is a necessity during winter months, Texas needs to develop a way to cool buildings during much of the year due to high humidity and scorching temperatures. Cooling using solar energy is possible but complex since it requires an indirect technique to extract heat. The solar cooling technology was first displayed on a large scale at Trinity University in San Antonio during 1977. Texas Tech University was the first institution to develop a moderately sized solar-electric power plant in the United States. The solar-electric power plant developed by Texas Tech replaced the diesel-fueled generators used to power the City of Crosbyton. The device used to harness solar energy and convert solar radiation into electricity has been modified for usage at the Johnson and Johnson plant in Sherman, Texas as an economical electricity generating alternative (Wilder, 2013).

Solar energy is clean, eco-friendly and also sustainable. Due to the fact that the energy produced from the

Renewable energy has the ability to play a major role in the energy industry of the twenty-first century. Shell and other big oil companies are ironically investing in renewable energy sources. Environmental experts realize that renewable energy helps reduce emissions of greenhouse gases. They also predict that by the year 2050, renewable power may grow to supply half the world’s energy. It may seem unreachable, but generating electricity by using the constant power of the sun and wind is already a reality. Solar power relies on the energy produced by the sun, storing energy for nighttime as well. “This energy can be converted in many ways, such as simple water heating or by the direct conversion of sunlight to energy using mirrors or boilers” (Riley).

Refrigertion systems that use environment-friendly refrigerants provide a property advantage when put next to other refrigerant alternatives. However, the energy use associated with cooling operation and therefore the environmental impacts associated with its genration and distribution usually outweigh the choice of refrigerant. to attenuate environmental impacts associated with cooling operation, it 's affordable to guage the prospects of a clean supply of energy. Research has incontestable that solar power is a perfect supply for low-temperature heating applications like area and domestic hot water heating. From a property perspective, directly victimization star as a primary energy source is engaging as a result of its universal availability, low environmental impact, and low or no in progress fuel cost.

Three weeks later, the vice presidents presented the sales and cost forecasts shown in the exhibits. The information presented contains the cost of production, financing information, and warranty cost estimates. In addition, there were two options for the compressor in the refrigerators. The MC – 004 is more expensive to install, but has a lower warranty cost. The TS – L12 is cheaper to install, but has a higher warranty cost. Which compressor should be used?

It is one of the cleanest sources without any emission of harmful gases and is in a great demand today. When these are converted to electricity for commercial as well as residential uses, there are no effects on the environment, no air pollution, noise pollution or any wastes. These can play a very important role in reducing greenhouse gas emissions by replacing coal-powered energy sources with clean, renewable solar technologies which improve air quality and lessen the harmful impacts that contribute to climate change. Residential solar gives the advantage of energy independence, fuel diversity, improved power reliability, increased price stability and reduced need to build more expensive and polluting electric power generation plants. The benefits of this are energy independence, protection against rising electrical rates, sound financial investment, reduce pollution and dependence on foreign oil. These benefits extend well and eliminate exposure to increasing energy costs and Solar power provides energy security. Photovoltaic (PV) power systems convert sunlight directly into electricity and enables homeowner to generate some or all of their daily electrical energy demand on their own roof, exchanging daytime excess power for future energy needs. It can plan an important role in providing an alternative source of electricity, energy, and back-up power for homes, offices, commercial and industrial buildings. Those who are putting solar on their homes, businesses or other buildings are making a

In the basic process of conversion of solar into heat energy, an incident solar irradiance is collected and concentrated by concentrating solar collectors or mirrors, and generated heat is used to heat the thermic fluids such as heat transfer oils, air or water/steam, depending on the plant design, acts as heat carrier and/or as storage media. The hot thermic fluid is used to generated steam or hot gases, which are then used to operate a heat engine. In these systems, the efficiency of the collector reduces marginally as its operating

In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.

Most consumers use heat, cooling, and other appliances in their homes. But have you ever thought the cost of running these appliances, or the way the fossil fuels that are produced effect the environment. Alternative energies (-- removed HTML --) are a possible solution to the issues of cost and damage to our environment. You, as a consumer of energy, can benefit from these financially through small scale photovoltaic solar and wind turbines. They both use "free fuel" to create clean energy. When you harness this energy and reduce the amount of carbon dioxide (CO2) in the atmosphere you actually save money in the long run. Throughout this lesson you will learn more about the ways photovoltaic solar and wind turbines could benefit you as a consumer!

Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.

Earth’s average temperature is projected to be roughly 1.1-5.4°C warmer in 2100 than it was in 2012 [1]. The increase might seem small in proportion to the amount of years it will take, but it will be very noticeable when the change occurs. Temperature becomes more evident inside of small buildings, or when they are crowded with people. People have counteracted the heat by inventing appliances and making advancements such as air conditioners, or fans; these cooling systems have done their purpose without error, but as prices of resources continue to incline, money may be a future problem. One of multiple ways to efficiently and effectively attack this problem is with passive cooling. It utilizes renewable energy sources like the sun and

Solar power is one of the most environmentally benign energy sources available. Just 20 days of sunshine produces the same amount of energy as everything stored in Earth’s reserves of oil, coal, and natural gas—yet does not come close to producing the same amount of environmental damage as even one of those options (Greentips, 2005). Solar farms are a clean renewable source that can meet high energy demands and can creates thousands of jobs in the future. It is also used during peak demand for electricity. During the hottest days, the panels are absorbing more energy while homeowners have the a.c. on full blast. They can be installed anywhere

* High efficiency refrigerators consume about100 kwh/year - this is 10 times less than the average in the U.S., and four times less than the EU average.

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.
