Since many families have 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, heating effect? Below is a small edition to explain it to you!
What is solar energy?
Solar energy generally refers to the solar radiation energy, it is the use of abundant solar radiation of energy.
Solar radiation energy is inexhaustible, renewable energy, no pollution, human can freely use, such as wind energy, water potential energy, chemical energy and so on.
Since the formation of the Earth, living things mainly live 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 photothermal conversion and viewpoint conversion.
1. The 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 for this, and it cannot function properly without a single solar energy.
2. Solar heating principle
The solar radiation passes through the jacket of the vacuum tube and is absorbed by the collector coating. After that, the water is transferred from the inner wall to the tube.
The temperature of the water in the tube will rise after the absorption of heat, the pressure is large, the formation of a power, the hot water moves up and stays in the upper part of the tank, constantly circulating.
3. How effective is solar heating?
Due to the large area of solar heat collection, focusing on the winter weather reasons, its design is comprehensive, so whether in summer or winter its heat collection effect is very strong.
Outside the solar energy is a metal material, we all know that the heat absorption effect of metal is very good, better help solar heat absorption.
The time of solar energy is very strong, sufficient in the day and zero at night, which is completely opposite to our heating time, but because the building is basically made of brick, stone and cement.
They typically release the heat of the day at night, and combined with certain heat storage equipment, solar energy can take advantage of this to absorb the heat of the building at night.
Using solar energy for heating is very popular and widespread. Everything has two sides, it has many advantages, but also has certain disadvantages.
4. Disadvantages of solar water heater:
A. In winter, the temperature is relatively low. Sometimes, the sun does not shine for several days in a row. Once the original hot water in the solar water heater is used up, it is difficult to reheat, resulting in no hot water;
b. Because of the large area of solar heat collection, the cost is high and the waste of equipment and funds cannot achieve the effect of saving;
c. Solar heating has higher requirements for buildings, which require buildings to face south for better lighting, etc.
Through the introduction of Xiaobian, you do not know more about how to warm the solar energy? Solar heating effect is generally good, mainly also very environmental protection oh!
