Working Principle of Air Heater

my prev post about Introduction to Air Heater . Solar air heating is a solar thermal technology in which the energy from the sun, solar insolation, is captured by an absorbing medium and used to heat air. air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications. It is typically the most cost-effective out of all the solar technologies, especially in commercial and industrial applications, and it addresses the largest usage of building energy in heating climates, which is space heating and industrial process heating.
The working principle of Air Heater Using Waste Cool Drink Cans unit is simple one. The rays of the sun contain a large amount of heat energy. This heat energy utilized by cool drink cans when the sun rays fall on this unit, the black coated tins absorbs the solar rays by means of radiations .so that surrounding atmosphere air inside of this unit is also heated.
This design for a solar collector comprises a black painted cool drink cans which absorbs the solar radiation and converts it into heat and a sealed cavity on top to trap the heat within. The heat is extracted from the end cool drink cans and circulated by fans.
Solar energy has the greatest potential of all other renewable sources of energy. The utilization of solar energy in various engineering applications with new technical skills it has attained to maximum important in the present content of energy crisis.

Off cuts of 1800mm x 700mm and a sheet of plywood were used to build a box to tightly hold 8 rows of 10 black-painted aluminum drinks cans. The inside of the box was then sealed using caulk toprevent hot air from escaping. Cold air is drawn in from a hole at the bottom of the box, and the heated air emerges from the top passing through a pipe into the garage to be heated. A plexus-glass sheet was glued to the box to let sunlight in but not let the hot air escape.

Air Heater using Cool Drink Cans

Air heater Intoduction

Energy is expected for the existence of the universe and source of it is the sun. The major problem experienced in all the country is the non-availability of synthetic and fossil fuels. If the country’s which low availability in fuels can prove their economy by following the non conventional energy sources such as solar energy, wind energy, Geothermal energy and etc..,
Solar air heater is a device which is used to produce the hot air for any industrial or farmer level drying application by heat energy received from the sun, without using any conventional fuels like diesel, LPG, coal. Firewood etc.., But it could be coupled with an existing conventional drying system like Tray driers, Tunnel driers, conveyor drier, FBD drier and Bin drier operated by conventional fuels to save fuel consumption.
There are no pollution in this type of systems .There are two main solar thermal systems one is solar water heater and another one is solar air heater. Solar air heating provides a supplementary heating to the air in a room during day times. In this project waste cool drink cans are used. The cans are made up of aluminum. There is the heating material of the air heater.  

Using the sun to heat the water  is a very cost effective way to save energy. Typically payback on even the most expensive systems is under ten years, with diy solar water heaters paying for themselves in just a few months. Similar techniques can be used to make a solar space heater - a device which warms the air inside a room or building
to know more about Air Heater using waste cool drink cans. By using this we almost heat the the garbage without any cost what we have to do is drink lot of soda

What is Search Engine Optimization (SEO)- beginner understanding

Search engine optimization is used to optimize the website.this optimization will help the user who search on the search engines like google,yahoo,bing,etc.the SEO will help to list our webpage into the top level of the page on the search engines.

Now we are live in fast based environment, Around 3 billions users are having internet facility all over the word and this still growing rapidly. We all know the internet users are too quick they want everything to be happen so fast .so if you we own webpage or online store is very helpful to enlarge your business or to exhibit your skills to the world.mostly the users use search engines to accquire what they want . but to attract the internet users to our website is some what difficult. Even though we have the stuff what the user need , still it is diffcult to bring them to the site . this happens because our page is not search engine friendly. if our page is more friendly to the search engine and as well as to the users then our page came font on the search engine results based the user search term or qurrey. so we can except more page visits. for that our webpage must be search engine friendly.

Important Factors to be considered to apply SEO




and some backstage parameters. we will see about those parameters on upcoming posts..
