Das ist die Präsentation In Englisch. Falls das notwendig sein sollte, kann ich sie auch auf Deutsch noch beilegen. Da ich die Präsentation natürlich mit Poweroint mache, sind die Beschreibungen eventuell etwas unklar da keine Fotos vorhanden sind. naja, schauts auch einfach mal an wenn ihr Lust und Zeit habt
Introduction
Hello together. Everyone of you already heard something about solar energy. In my short presentation I would like to deepen and strengthen this knowledge still somewhat.
Overview
1. First I would like to speak briefly about the different kinds of the solar energy use and the different systems.
2. Secondly we look the principle and the structure of a collector
3. Thirdly I would like to speak about function modes and the different systems
4. At last I will give you a small review of the whole again.
Main body
1. The solar technology concerns itself with the use of the solar power. The Potential of the energy source sun is enormous. In only 20 minutes so much solar energy arrives on earth, as the mankind uses in a whole year. The solar power is used in Switzerland mainly in two different kinds.
On the one hand the solar power is converted with the help of the Photovoltaic into electricity. Meanwhile it is used for generation of electricity in the whole world. It is used by automats, on the roof age or on open spaces.
In my presentation I deal however mainly with thermal solar systems and their use. Thermal solar system use solar warmth to the support or covering of the warm water need and the heating. The central construction unit is the solar collector also here.
2. The principal item of a solar system is the black absorber in the collector, which warms up under the sun isolation. Inside there is a pipe system, so that the won warmth with a special medium can be dissipated. So that the largest part of the produced warmth as possible can be used, collectors are thermal insulated on the back and at the side panels. The liquid warmed up in the absorber delivers the entire warmth over a heat exchanger at the warm water and heating system.
The structure of the collectors is relatively simple. At first the solar glass comes. On the second view the black absorber, which is to absorb the jets and convert into warmth. Among them comes the copper tube distribution with the special medium. Under it and at the sides the whole collector is thermal insulated directly.
3. Mainly there are two different system. With the first system only warm water is produced.
As you can see here, the collector is placed on the roof. Over the lines the warmed up medium arrives into the heating element in the hot water tank and by means of the pump again back into the collector. Additionally an additional heat production is inserted. Over the hot water tank the warm water can be distributed.
With the second system by means of the collector also the heater water is warmed up. Here the custom hot water tank is integrated into the hot water tank of the heating.
The user of solar systems can smile about the high prices of oil and gas. The sun does not send a calculation. Solar systems are future-oriented and lasting.
Review
4. There are two different systems for the use of the solar energy. On the one hand the solar power is converted with the help of the Photovoltaic into electricity and on the other hand the solar warms used. The most important components of a collector are the collector glass, the absorber, the copper lines and the thermal insulation. The warmth produced by the collectors can be used for the production by custom warm water and for the heating up of the heater water.
Closing
Solar energy is energy with future. It is a simple system with large effect. We as future building technology engineers are obligate to sell and build such systems. Our descendants will thank it to us.
Na was meint ihr?? Ist das zu gebrauchen oder völliger Schwachsinn
