Nano Sized Air Cooler
The performance of heat transfer is one of the most important research areas in the field of thermal engineering. There are a large number of refrigerants, which are used to transfer heat from low-temperature reservoir to high-temperature reservoir by using vapor compression refrigeration system. There are various obstacles faced in working of different refrigerants due to their environmental impact, toxicity, flammability and high pressure; which makes them more hazardous than other working fluids according to safety and environmental issues. Researchers observed the performance of different environmental friendly refrigerants and their mixtures in different proportions. They also observed the effect of working parameters like dimensions of the capillary tube, working pressures and working temperatures, which affect the coefficient of performance of vapor compression refrigeration system. From the literature, there seems to be need of new efficient, minimum global warming potential, minimum ozone depletion potential and environmentally friendly refrigerants. The air conditioner and air cooler are widely used in the world. These electrical devices consumed more electrical power and it does not benefit for the poor people. In practice, power shortage also occurs. These problems are rectified by modification of ordinary table fan. In the summer season, the ordinary table fan gives the small amount of cold air in the room. So the table fan is modified by using the copper tube with fins and special design Cooling Chamber. In this project the cooling of air by using cold water or any other refrigerant which is circulated in the copper tube for the purpose of reducing the heat in the surrounding environment, where it is of great importance in widely distributed villages with little or no rural electrification and also in the urban areas where power shortage is often in practice. Air cooling is a method of dissipating heat. It works by expanding the surface area of or increasing the flow of air over the object to be cooled, or both. An example of the former is to add cooling fins to the surface of the object, either by making them integral or by attaching them tightly to the object's surface. In the case of the latter, it is done by using a fan blowing air into or onto the object one wants to cool. The addition of fins to a heat sink increases its total surface area, resulting in greater cooling effectiveness.
