Modelling, Development and Study of Fin Type Solar Air Heater. Renewable Technology

      Аннотация: It is well known that solar energy is an unlimited resource of heat on the earth. The sun produces an enormous amount of energy which can convert into heat and electricity. The amount of energy incident upon earth surface in one hour is more than mankind use in one year. The amount of solar radiation incident on the earth surface per year is about 3.9?1026 W. Some part of the incident solar energy is reflected back to space. That part of the radiation is called the albedo. The solar air heater is the foremost component of the solar energy utilization systems. The solar air heater is a device which heats the air by using solar energy. The solar air heaters are used, where the temperature requirements are less than 65?C. The solar air heater is mainly used in space heating, drying agriculture and industrial purpose.
