Solar Powered Fridge Technical Report - Essay Example However majority of the mankind which lives in the developing or third world countries has just recently woken up to the benefits of refrigeration. As these countries continue to grow rapidly, their people will require refrigeration in some form or other. Refrigeration is required not only for keeping food fresh but is also needed for transportation of perishable products like meat, milk etc (score.uk, 2013). Although the need for refrigeration is huge, third world countries are suffering from immense energy crisis. Most of these countries do not have the resources to provide electricity to the entire population. Where electricity is available, there are problem of irregular supply and voltage problems. A huge amount of capital is also required to set up power plants in order to provide electricity to all. Such huge amounts of capital are rarely available in third world countries. After the Kyoto protocol, there is also a raised concern of environmental sustainability of economic gro wth. The model of growth being followed by developed nation is simply not sustainable. Solar power addresses both these concerns – neither does it require immense investment to ensure electricity supply nor does it harm the environment. Solar powered refrigerators thus provide an ideal solution to the refrigeration needs of the third world countries. This paper discusses the functioning of a solar powered refrigerator. It discusses the 2 prototypes - Evaporative Cooler fridge and absorption based heat driven coolers. Evaporative Cooler Fridge The most amazing thing about an Evaporative cooler fridge is its simplicity. It is very simple to make and can be made with the use of minimal resources in third world countries. The diagram of an evaporative cooler fridge is shown below – Source: (score.uk, 2013) Construction The fridge consists of 2 cylinders. The outer cylinder can be made up of cardboard, plastic or any other material. It should have a lot of holes in it to al low the maximum access to solar energy .The inner cylinder should be made up of a good conductor of heat. Iron or steel are the best possible materials which are easily available and also good conductors of heat. The inner cylinder should not have any holes. The space between the two cylinders needs to be filled up with a material which is a good absorber of water. Sand and wool works best here. Food or any other material which needs to be kept cool should be kept in the inner cylinder. The next section explains the working of this refrigerator. Working This fridge works on the simple principle of evaporation of water and conduction of heat. In order to â€Å"start the fridge†; pour water in the space between the two cylinders. This water will be soaked by the sand. It is important to fill the space with sand in order to allow slow evaporation of water and ensure that minimum refills are required for the successful working of the refrigerator. As solar energy falls on the san d evaporation of water from the sand takes place. As water evaporates, the process of conduction of heat will ensure that heat is extracted from the inner chamber in order to help the water evaporate. This conduction of heat will keep the chamber cold and the products inside fresh. The chamber can attain temperature of up to 6 degrees. In order to ensure that the fridge keeps working, the

Outline and evaluate the negotiating skills you have used Essay

Outline and evaluate the negotiating skills you have used - Essay Example Specified means of negotiations can be utilized in numerous situations, be it in legal systems, industrial disputes, government, or domestic relationships. General negotiation skills are learned and applied in an extensive range of activities to resolve any difference that arise in a work place. I was working in the United Credit Bank in Azerbaijan, during my internship, where I used to deal with the reporting process. On several occasions, I used my negotiation skills to be permitted to make some significant changes in my reports. However, it could have been more successful if I could have identified these issues prior to producing the report, so I wouldn’t need to enquire from my manager to give me permission for making the changes in the reports. As much as the idea was not viewed negatively by my manager, I realized that I could have behaved in a more successful way. Some of the negotiating skills I used include the following: Preparation First, I used to prepare myself fo r the negotiations by deciding on when and where I would meet my manager after writing my reports. At this stage, I also used to limit the time I could use when asking her of any issues to prevent any disagreement and unnecessary conversations between the two of us. I always made sure that I have gone through my reports especially those concerning any monetary records to be fully aware of the facts so that it could be easier for me to clarify my position to the manager. In this context, I specifically went through the rules and regulations of the bank and made sure they were on my fingertips to prove that I had not violated any policy. By this, my boss could not spend much time trying to clarify information that she expected I was familiar with (Nadler, 2003). Analyzing the problem As a bank employee at that time, I had to ensure that my internship become successful, hence I took my time to determine what my manager really expected of me. Before I could approach her, I used to analy ze the issues in my reports, especially in record keeping so that both our interests could not disagree. I often detailed by analysis by identifying the interested parties, such as the manager herself, the auditor, and other executives, and spot out the issues they could have criticized. However, sometimes I could not single out the real issues as required. Active listening during discussions Putting in mind that I often did not spot out the actual issues of concern, I could forward my cases exactly the way I saw them. Major skills used here included questioning, clarifying, and listening to my manager. Sometimes I could take notes as she explained to record important points put forward just in case I needed more clearing up. Nevertheless, it came to my notice that I rarely applied this skill efficiently because I tented to concentrate more on noting than listening. This led to hardships at some points as she could end up talking too much than I expected and that I never got an equa l chance to present my case as she always did. Another impact I noted when I seemed to write much and listen less was that I failed to notice her body language, which could have enabled me to know if she was happy with my questions or if she demonstrated something important. She could at times forbid me from writing and use my pen to illustrate her point by rectifying the issues in my reports, and this is when I often concentrated.
