Energy saving review about which professional does the embodiment of solar energy

Solar energy supporting projects include a lot, such as solar hot water, solar heating, solar air conditioning, solar photovoltaic power generation and so on (and a lot) of technology, many manufacturers but the technology is uneven, can do very little, can have fewer application cases, the choice of manufacturers must be cautious.

<> a variety of examples of the combination of solar energy and buildings.

Trina Solar. Hanergy Solar.

Canadian Solar.

It's all about solar power generation, and the technology is fine.

The uses of solar energy are mainly reflected in the utilization of solar heat, power generation, actinization and fuel.

1. Utilization of light and heat.

Solar radiation energy is collected and converted into heat energy through interaction with matter. At present, there are four most widely used solar energy collection devices: flat plate collectors, vacuum tube collectors, ceramic solar collectors and focused collectors.

2. Power generation and utilization.

Solar power generation is widely used in solar street lights, solar insecticidal lamps, solar portable systems, solar power supplies, solar application products, communication power supplies, solar lamps, solar buildings and other fields.

3. Actinic utilization.

This is a photochemical conversion method that uses solar radiation energy to directly split water to produce hydrogen. It includes photosynthesis, photoelectrochemistry, photosensitive chemistry and photodecomposition reactions. Actinic conversion is the process of converting into chemical energy due to the absorption of light radiation resulting in a chemical reaction.

Its basic forms are photosynthesis of plants and photochemical reactions that use chemical changes in substances to store solar energy.

4. Fuel utilization.

Using the high-temperature energy generated by the concentrated concentration of sunlight, supplemented by metal oxide material additives, water and carbon dioxide are converted into syngas in a self-designed and developed solar high-temperature reactor. The waste heat of high-temperature syngas is converted into a finished "solar" fuel product that can be commercialized in the market.

Recently, I often see an Internet celebrity solar artifact on the Internet, called a solar barbecue grill, which uses solar energy to cook, and the weight is very light about 4 catties, and it is said that it can roast 2 catties -5 catties of meat. It's all available online.

Not to mention the micro-use of solar energy, such as photovoltaic panels, water heaters, and barbecue grills.

Let's talk about science fiction: the sun is an inexhaustible energy pile, how to use it?

Like a beacon, a series of satellites are launched infinitely closer to the Sun, absorbing energy and then teleporting back to Earth. The premise is to overcome the technology of wireless transmission of this energy (including electrical energy), the earth is rotary, and several receiving devices can be installed at the equator, and Tesla's current wireless high-frequency transmission is unfortunately lost.

Engage in giant batteries + UFOs to absorb energy near the sun and send it to the earth for 10 or 20 years.

To create a small sun on Earth, the best energy source is to produce quantum fission and fusion from seawater, which is enough for humans to drink a few pots.

Solar water heater! It is water that can be used for people's daily life and industry after heating! Commonly used in home showers, hair salon shampoos, industrial equipment hot water**, etc.!

Solar water heater has the advantages of energy saving, environmental protection, low carbon, etc., relying on sunlight for heating, and can also use electric heating, with strong applicability!

Solar energy does not account for any coefficient in the energy-saving calculation, only accounts for the proportion in the judgment of green building, energy-saving calculation refers to the energy-saving measures made by the project in the exterior walls, doors and windows, roofs and other parts, and solar energy has nothing to do with it.

Because it has the following advantages:

1) It can effectively use solar energy, which can achieve low cost and high efficiency, reduce the consumption of commodity energy, and alleviate the contradiction between supply and demand of energy sources, which is an important way to save energy in buildings;

2) The use function of the building is organically combined with the solar energy facilities to form a multi-functional building component, which makes clever and efficient use of the building space;

3) The construction at the same time of design can reduce the building load, reduce the cost, and prevent the inconvenience to the user's life and the damage to the building structure caused by the later installation;

4) Form a unified and coordinated architectural form, the solar energy facilities are integrated into one with the building, the structure is reasonable, and a complete and unified building appearance is formed;

5) China's solar energy resources are very abundant, and the integration of solar energy and building has opened up and laid a broad application prospect for the development and development of the solar energy utilization industry.

China's expansion in the field of solar thermal utilization, especially the comprehensive introduction of solar energy into the field of construction, is a major feature of the world, which is in line with the national conditions of China's urbanization development. At present, nearly 2 billion square meters of buildings are completed in China every year, about 70 are residential buildings, and among the existing buildings, 99 are high-energy buildings, and the power consumption during the peak period is equivalent to the full load output of 10 Three Gorges hydropower stations. Therefore, it is feasible to vigorously promote energy conservation and emission reduction starting with buildings.

According to the People's Republic of China.

DU National Standard (GB T 2589-2008) Comprehensive ZHI Energy Consumption Calculation General Principles, calculated and filled in by the project DAO construction unit, and added the official seal of the internal reform to report to the * Energy types include: raw coal, natural gas, hydropower, wind power, solar energy, biomass energy, refined coal, other coal washing, briquette, coke, coke oven gas, other gas, gasoline, kerosene, diesel, fuel oil, liquefied petroleum gas, refinery dry gas, other petroleum products, other coking products, heat, electricity, etc.

The types of energy-consuming working fluids include: fresh water, demineralized water, compressed air, oxygen, nitrogen, helium, acetylene, calcium carbide, etc. To calculate the annual physical demand, the annual energy consumption can be calculated by referring to the standard coal coefficient in Appendix A and Appendix B in the General Principles for Calculation of Comprehensive Energy Consumption.

Hepai energy-saving equipment, this company has more than ten years of experience in hot water engineering, quality and service are very good.

To do solar water heating projects, choose Four Seasons Muge, clean heating, indispensable!

Where is the project, the first choice for solar water heating is Huangming solar water heating project, specializing in hot water for 24 years, and the quality is guaranteed.
