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:Total energy consumption and total energy production
The output of the refinery, gasoline, kerosene, diesel oil, fuel oil, liquefied petroleum gas, refinery gas and other petroleum products (naphtha, solvent oil, raw oil, paraffin wax, lubricating oil, asphalt, etc.) gas output is the coke gas and other gas, coke and other coking products (coal tar crude, etc.).
Q:At present, what are the main types of new energy vehicles?
Hybrid electric vehicle:Refers to the use of conventional fuels, while with motor or engine to improve low-speed power output and fuel consumption models. In accordance with the different types of fuel, hybrid vehicles can be divided into two types of gasoline hybrid vehicles and diesel hybrid vehicles. At present, the mainstream of hybrid vehicles in China are mainly gasoline hybrid, while the international development of diesel hybrid models are relatively fast.
Q:What are the contents of bio energy
Many types of biomass specific plants, the main and we often see the wood, crop (straw, rice straw, wheat straw, cotton stalk, bean stalk, rice husk, weed and algae etc.). Among the non plant species, there are mainly animal manure, animal carcasses, organic components in wastewater and organic components in waste.
Q:What is the energy consumption per unit product
Formula: (1) comprehensive energy per unit of product yield comprehensive energy consumption per unit of product yield consumption = production of comprehensive energy consumption of the product (equivalent) / qualified product yield (2) yield of single unit product energy consumption per unit of product yield of single energy consumption = production of the product consumption of a variety of energy the number of qualified products yield (3) than the unit energy consumption of products according to the standard procedure to calculate the energy consumption than the unit energy consumption = comprehensive energy consumption according to the standard calculation of the amount of qualified production process / product yield can be calculated according to the standard energy consumption than single bit = yield statistics method of comprehensive energy consumption volume / year range: standard products report on the production of major products for the annual energy consumption of 5000 tons of standard coal and above the legal unit. The index of the sub item is the production of a product of a number of varieties of the total energy consumption of energy, not including production has nothing to do with the amount of energy for the purpose of life, nor does it include internal recycling energy and enterprise basic construction unit consumption using waste heat and gas; mother is qualified, have procedures for storage products production.
Q:What is new energy science and Engineering
The professional training with the theory of heat and mechanics, machinery, energy science, system engineering and so generous, grasp the solar and wind energy, biomass energy and geothermal energy and other new energy professional knowledge, can be engaged in the production of clean energy, renewable energy development and utilization of energy, environmental protection, new energy development, engineering design, optimal operation and production management, cross discipline of advanced composite talents with comprehensive ability, strong innovation spirit and practical ability. Graduates in energy, construction, transportation, materials, electronics, environmental protection and other industries engaged in new energy and renewable energy products R & D and production, engineering design and construction, as well as teaching, research and management, etc..
Q:What is the cost effectiveness ratio of energy management in energy quality?
I guess what you are saying is the "efficiency" in the international energy standard
Q:What is the comprehensive calculation of energy production?
In order to comprehensively reflect the total energy production, various energy products must be calculated according to the different calorific value of the common conversion standards. In China, the standard coal is calculated, and the calorific value per kilogram of standard coal is 7 million.
Q:Trademark registration of energy and environmental protection is the first category
There are 45 categories of trademark classification in China. Firstly, it is necessary to choose the categories corresponding to the enterprises, and the trade mark should belong to the 11 category:Article 01: used in industry, science and photography, agriculture, horticulture and forestry chemicals, unprocessed artificial resins, unprocessed plastics material, fertilizer, fire extinguishing compositions, tempering and soldering preparations, preservation of food chemicals, tanning, industrial adhesives
Q:There are several forms of energyWhat are they called? What is the use?
They become the basis of global energy; in addition, solar energy, wind energy, geothermal energy, ocean energy, biomass energy, nuclear energy and other renewable energy is also included in the scope of primary energy; two energy refers to the primary energy directly or indirectly into other types and forms of energy resources, for example electric power, gas, gasoline, diesel, coke, clean coal, gas and other energy laser and belong to two energy.
