Since many families entered a well-off society, solar energy has also been widely used and is an indispensable part of the family.
The main function of solar energy is heating, so how does it heat and what is the heating effect? Let me explain it to you below!
What is solar energy?
Solar energy generally refers to solar radiation energy, which is the energy radiated from the sun.
Solar radiation energy is inexhaustible, renewable energy, non-polluting, and can be used freely by human beings, such as wind energy, potential energy of water, chemical energy and so on.
Since the formation of the earth, organisms have mainly lived on the heat and light provided by the sun. Solar energy has been widely used by people. There are two forms of solar energy, namely light-to-heat conversion and viewpoint conversion.
1. Composition of solar energy
It is composed of automatic exhaust valve, vacuum-free superconducting radiator, air valve, water tank and so on. Every structure is essential to this, and without a solar energy it cannot function properly.
2. The principle of solar heating
The solar radiation passes through the jacket of the vacuum tube, is absorbed by the collector coating, and then transfers from the inner wall to the water in the tube.
After absorbing heat, the temperature of the water in the pipe will rise, and the pressure will be high, forming a power, and the hot water will move up and stay on the upper part of the water tank, continuously reciprocating.
3. How effective is solar heating?
Due to the large area of solar heat collection, the design is comprehensive in consideration of winter weather, so its heat collection effect is extremely strong no matter in summer or winter.
There is a metal substance outside the solar energy. We all know that the heat absorption effect of metal is very good, which better helps the solar energy absorb heat.
Solar energy is very time-sensitive, it is sufficient during the day and zero at night, which is completely opposite to our heating time, but because buildings are basically made of bricks, stones, and cement.
They generally release the heat absorbed during the day at night, and with certain heat storage equipment, solar energy can use this to absorb the heat released by buildings at night.
Solar heating is very popular and widespread. Everything has two sides. Although it has many advantages, it also has certain disadvantages.
4. Disadvantages of solar water heaters:
a. The temperature in winter is relatively low, and the sun will not come out for several days in a row, and it will not be out for more than ten days. Once the original hot water in the solar water heater is used up, it will be difficult for it to heat again, resulting in no hot water;
b. Because of the large area of solar heat collection, the cost is high, equipment and funds are wasted, and the effect of saving cannot be achieved;
c. Solar heating has higher requirements on buildings, and buildings need to face south to get better sunlight.
Through the introduction of the editor, do you know more about how solar energy is used for heating? Generally speaking, the effect of solar heating is good, and the main thing is that it is very environmentally friendly!
