What is the principle of solar water heater? Solar water heater components

Water heaters are one of the indispensable items in every family. When we choose, we pay attention to its practicality. There are many types of water heaters now, and we don't know what is suitable for our own home when we choose. So everyone knows what is the principle of solar water heaters? Today, Xiaobian will take a look at the principle of solar water heaters and the components of solar water heaters!

Solar water heater principle:

1. Solar water heater is a major industry in the application of solar energy. It has won the favor of consumers with its advantages of environmental protection, safety, energy saving and sanitation. China is an energy-consuming country with annual energy consumption. The world's total energy consumption is 1∕3, and one-third of the country's total energy consumption comes from building energy consumption. "To the roof to energy", solar water heaters are the radiant heat energy that absorbs the sun, heating cold water to provide energy-saving equipment for people to use in life and production.

2. Solar water heaters are safe, energy efficient, environmentally friendly and economical. In particular, solar water heaters with auxiliary electric heating function, which is based on solar energy and supplemented by electric energy, enables solar water heaters to be used throughout the year. The solar collector does not have a gap like a vacuum tube. It is a continuous plane. When illuminated by sunlight, the entire collector surface can accept sunlight. Therefore, under the same lighting area and sunshine intensity, the average daily efficiency of solar water heaters is 6% higher than that of vacuum tubes. The heat absorbing plate of the solar collector is made of metal material, and the connection between the collector and the water storage tank is also made of metal parts, so it can withstand from

The pressure of tap water and circulation pump.

Solar water heater components:

1. Solar energy is also an electrical product consisting of multiple components, among which collectors, insulated water tanks, and brackets are among the main components of solar energy.

2. Collector: The collector is the collector element in the system, and its function is equivalent to the electric heating tube in the electric hot water pipe. The solar collector mainly uses the radiant heat of the sun, so its heating time can only be carried out when the sun illuminance reaches a certain value during work.

3. Insulation water tank: The heat preservation water tank is a kind of container capable of storing hot water. The hot water collected by the heat collecting tube must be stored in a water tank capable of keeping warm to prevent the loss of hot water heat. In a solar water heater, its capacity refers to the amount of water that can be used in a water heater, but does not include the capacity in a vacuum tube. In the insulated water tank, its inner tank is an important part of the water tank. Therefore, the strength and corrosion resistance of the inner tank material is very important. Nowadays, the better heat preservation method is the polyurethane foaming process for heat preservation.

4. Bracket: The bracket is a shelf for supporting the water heater and the heat preservation water tank. The bracket used by the solar water heater needs to ensure the firm structure and the stabilizer is also high. Under normal circumstances, the solar water heater is made of stainless steel.

5, control components: solar energy to run, its control system is indispensable, usually its controller in the solar water heater is automatically water, water or water and shows the water temperature and water level, with auxiliary electric heating The solar water heater also has the function of leakage protection and anti-drying.

The problem we need to understand when we choose a solar water heater is how it works and what its accessories are. Only in this way can we purchase it. The above is the principle of solar water heaters introduced by Xiaobian today and the components of solar water heaters are here. I want to know more information, please continue to pay attention to the decoration home.
