Q:Energy consumption classification of electronic products in China
At present, more than and 100 countries have implemented energy efficiency labeling system. For the blue and white background color identification, divided into 1, 2, 3, 4, 5 a total of 5 grades,Level 1 indicates that the product has reached the international advanced level, the most energy saving, the lowest energy consumption;
Q:Trademark registration of energy and environmental protection is the first category
Article 06: common metals and their alloys, metal building materials, transportable buildings of metal, metal rails, non electrical cables wires, five metal fittings, officer, safe, general metal products not included in other classes, oreClass 07: machines and machine tools, motors and engines (except for land vehicles), machine transmission couplings and transmission parts (except for land vehicles), non manual agricultural tools, incubatorsArticle 08: hand tools and implements (manual), cutlery, knives, razorArticle 09: Science, navigation, surveying, electrical, photography, film, optical, weighing, measuring, signal, inspection (supervision), ambulance (rescue) and teaching apparatus and instruments, apparatus recording, transmission or reproduction of sound and image, magnetic data carriers, recording discs, since the mechanical structure dynamic sales device and coin operated devices, cash register, computer and data processing device, fire extinguishing apparatus
Q:Metro energy feedback products which good?
Before the subway brake is to use the electricity directly with the resistance to let go, so that it will cause a waste of electricity, as well as investment in two refrigeration equipment, this is very environmentally friendly. Shenzhen Sheng Hong electric for this problem has developed a product called UESS, to solve this problem, but also to solve the UESS Metro Traction voltage problem.
Q:What is the comprehensive calculation of energy production?
Energy production is not equal to the sum of all kinds of energy into standard coal, because the two energy is generated by the primary energy conversion, so the total energy production can only be a variety of primary energy production and the standard coal
Q:Energy Star certified product range
Upstairs to answer the news, is the United States energy saving certification, a lot of IT, TV/AV products have to do energy star; but the United States has a California CEC certification, but also energy-saving certification, but different from the energy star
Q:China's new energy marketing plan
Two, the determination of research methodsThree, work planFour, pending buyers survey quotaIn five, the second-hand inquiry collectionSix, cost budget and detailSeven, research quality control
Q:Firewood (dry) is what type of energy
biomass energyBiomass refers to the use of air, water, land, etc. through photosynthesis and the production of a variety of organisms, that is, all living organisms can grow organic matter known as biomass.
Q:What is the difference between primary and secondary energy sources two
The primary energy obtained by processing the converted energy products, known as the two energy, such as electricity, steam, gas, gasoline, diesel oil, heavy oil, liquefied petroleum gas, ethanol, methane, hydrogen and coke etc..
Q:What are the new energy sources?
Microbial fermentation: many countries rich in sugar cane, sugar beet, cassava and other world, the use of microbial fermentation, can be made into alcohol, alcohol has complete combustion, high efficiency, no pollution, can be obtained by the "ethanol gasoline" diluted gasoline and alcohol rich raw materials, low cost. According to reports, Brazil has modified ethanol gasoline or alcohol fueled cars up to hundreds of thousands of vehicles, reducing the air pollution. In addition, the use of microorganisms to produce hydrogen, in order to open up new ways of energy.
Q:What is a one-time energy
Primary energy, also known as natural energy, refers to the use of natural resources that have not been changed or changed. Such as coal, crude oil, natural gas, water, wind energy, solar energy, ocean energy, tidal energy, geothermal energy, natural uranium, etc.. Primary energy is divided into renewable energy and non renewable energy, the former refers to the repeated generation of natural energy, the latter with a little less, mainly all kinds of fossil fuels, nuclear fuel.
