Hello, solar energy is more energy efficient when it comes to factory heating, because its heating surface is relatively large. A heating area of 1000 square meters requires a collector area of 250 square meters. The black porcelain old man is very suitable for solar energy projects. The heat absorber does not decompose, resists exposure to air, has a long collector life, is antifreeze and prevents overheating.
How do solar power plants work?
Solar water heater is a type of water heater that we often use in our daily life, and it has gradually begun to be used in industrial production. Industrial solar water heaters are used in industry and can provide hot water in many areas, such as brewing and fermentation, product drying, production preheating, active and passive heating, etc.
In many food factories, air is needed to dry food. The required air temperature is 60 degrees. Some companies will use solar water heaters to do this. When the water temperature in the buffer water tank reaches or exceeds 60 degrees, an air heat exchanger is used to directly heat the production line. When the water temperature in the buffer water tank is lower than 60 degrees, a water source heat pump is used to extract heat from the buffer water tank. After conversion by the compressor, it becomes high temperature heat and is used to heat the buffer water tank. production line through the finned condenser.
Boiler preheating installations can use solar water heaters. Plate heat exchangers are connected in series to the boiler return pipeline. LWhen the water temperature in the buffer water tank is 15 degrees higher than the water temperature in the return water pipe, the system automatically starts the circulation pump between the plate heat exchanger and the water tank to transfer heat from the water tank to the return. boiler water pipe. It is estimated that this project will be able to recover all the investments in only about 3 to 4 years.
For example, in a soy sauce fermentation tank, water is needed to maintain the temperature and avoid the loss of condensed water generated by daily steam heating. In the design, a solar water heater is used to sense the temperature. water bath temperature regularly every day. If the temperature is low According to the required temperature of the water bath and the water temperature of the solar buffer water tank is 5 degrees higher than that of the water bath, the systemteme heats the water. bath water through the plate heat exchanger. If the temperature is insufficient, an alarm will automatically sound to remind the service personnel to start steam heating. to ensure continuity of production.
The use of solar water heaters in industry can make full use of this cheap low-temperature heat source, making more full use of energy and reducing production costs for many companies. Today, they have gained favor in the market and have played a huge role in many industrial productions. I believe that as people's understanding continues to deepen, industrial solar water heaters will provide greater assistance to industrial production.
A solar power plant is a factory that uses renewable energy - solar energy to produce electricity. It works using thePhotovoltaic technology that converts solar energy into electrical energy. Currently, Germany uses solar energy to generate electricity capable of meeting the electricity needs of 550,000 homes. It is the world champion in the use of solar energy to produce electricity.
Currently, there are three main types of solar cells: monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells have the highest conversion efficiency, reaching over 20%, but they are also the most expensive. Amorphous silicon solar cells have the lowest conversion efficiency. But it is the cheapest and most promising battery for general power generation in the future. Once the photoelectric conversion efficiency of its large-area components reaches 10% and the price ofpower generation equipment will fall to 1 to 2 US dollars per watt, this will be enough to compete with current electricity generation methods.
