1.7 PROBLEM IDENTIFICATION
The solar energy is backbone for human beings. So with use of solar energy we can reduce the pollution and all global worming problems which is major issue for any countries in now a days. By using solar energy we can reduce the consumption of electricity and fossil fuels. But the major problem with these solar technologies having low COP, High initial cost, Availability of Sun.
Now a days, many Solar based refrigeration s system are Available. In Simple Solar based Vapour absorption Refrigeration system the heat is required in generator for supplying heat to the strong solution (mixture of Refrigerant and absorber). But problem with these type of s system is that it cannot be used in the absence of sun and at the time of night. Though major problem with these system cannot use at the time of night and absence of sunlight. So we are trying to find out the material which can store the solar energy at the time of day and this store energy can be used at the time of night.
1.8 ADVANTAGE & DISADVANTAGE
Advantages:-
• India is the among the world leaders in agriculture production however much of our produce goes waste due to absence of storage facilities. Refrigeration is thus vitally important for our country.
• Milk produce is also adversely affected due to lack of refrigeration.
• Cool drinking water is unavailable to people of non-electrified villages.
• Medical facilities are also affected due to break in cold chain as

Article 1 David Nelson Crosthwait Jr was born in Nashville, Tennessee on May 27th in 1898. He is and african american pioneer in the field of heating and air conditioning. He is best known for heating up Radio City Music City in New York City. Crosthwait grew up in Kansas City,Missouri, where he attended all-black school. His parents were very encouraging and challenged him to do experiments and to make designs.
Many of our dry vans include temperature control systems so we can keep your valuable produce from freezing even when the temperature is below zero
Globally, tackling this problem will take some serious reform in the way we use fossil fuels for energy. Therefore, I have a few proposals involving the use of albedo and solar panels that should they be adopted in
Customers may buy alternative food products. Expands its market share in other countries such as China. The better global economy would increase the target market. Legal and regulatory
Once the practice of keeping foods like milk sanitary, it will spread to the other foods like the meat packing industry and create a chain reaction of safety that helped to improve the lives of everyone with their experience of food and their health in
He uses his advocacy for air conditioning to gently approach the uncomfortable topic of our wrong-doings saying, “I’m hardly against air conditioning… it can save the lives of sick, elderly, and frail… [it] can enhance productivity and make factories safer for workers.” Gaining trust from the audience he continues to tackle the issue by suggesting that instead of complying with our expectation of having our thermostats set to “Igloo, arctic and frigid” we should use our air conditioning responsibly, such as reducing indoor temperatures to the mid-70s and no farther. However he is not convinced our culture would ever readily agree to limitations of this nature, therefore, Klinenberg suggests that there be new rules and regulations instituted concerning the use of air
Climate change has been a problem in the world since the industrial revolution and has been denied by major corporations and the government for centuries. This is because most non-renewable resources are major industries (i.e. oil, electricity, water, etc.) and the world 's economy profits from these resources. The bulk of corporations prioritize their wealth over the condition of the Earth beneath them. Economic growth is important for the people, yes; it is how we develop as a society, but at what cost? The Earth takes the brunt of society 's success, and denying the inevitable will not stop it from occurring.
• Remote Areas – Solar Panels can help to provide electricity to areas which may be far from another electrical source. Cons: • Initial Cost – Solar Panels are quite expensive to buy. • Access – Solar Panels can only work to their full potential if they have many hours of access to the sun per day. The longer the access, the greater energy
Global climate change is a very serious problem that we must pay close attention to. The main reason that causes climate change is that there are too many carbon dioxide in the atmosphere. If the temperature keeps getting higher and higher, there will be many problems that can cause great damage to us and the environment. If we don’t replace fossil fuels with other clean energy, our Co2 level will be as many as the time of the dinosaurs and we don’t know what will our lives be if this really happened. The best way to solve this is by using solar energy.
What is global warming? Global Warming is the increase of Earth 's normal surface temperature due to impact of greenhouse gases such as carbon dioxide radiations from lighting fossil fuels or from the removal of trees which lure heat that would otherwise get away from Earth. This is a kind of greenhouse impact. Global warming is the determined and relieved increases in the mean temperature of Earth atmosphere and oceans.
Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.
“Renewable energy resources that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun or from other natural movement and mechanisms of the environment. Renewable energy does not include energy resources derived from fossil fuels, waste product from fossil sources, or waste products from inorganic sources.” There are a few types of renewable energy sources. 1) Wind Energy 2) Biomass 3)
Introduction. One of the crucial problems that world facing is energy use and energy efficiency is the main solution for this issue. As Juodis (2009) mentioned, term energy efficiency has two meaning, namely minimal consumption of energy and cost-effective energy use which is smallest amount of energy consumption to keep convenient hygiene conditions in a building. Energy efficient construction should be compulsory in Kazakhstan.
As mentioned by Casper (2007), ‘Cold Chain Logistics deals with the production, processing, packaging station, cold storage warehouses, transportation, distribution centres, retailer, end consumer and in the user household refrigerators of products from the manufacture to the customer that are temperature sensitive.’ In this thesis, we are mainly concerned
