White over black why restrict escape energy constraints – white, black, energy efficiency standards – Network Appliance Industry-hc360 HC
2006 12 14, well-known scientists, Professor of Tsinghua Mao Yu interviewed said that with the economic development and improvement of living standards, computer, TV, stereo, home theater as the representative black appliances power consumption is rapidly rising, and the resulting alarming number of resource consumption. Related departments should take precautions, as soon as possible to develop energy efficiency standards for black and restricts black huge consumption of resources, to build a conservation-oriented society and make due efforts.
Recent years, refrigerators, air conditioners, washing machines and other white attaches great importance to energy conservation by industry, and the standard norms, the market is teeming vitality. However, computer, TV, stereo, home theater, represented by black appliances energy situation is very regrettable, neither industry standards, and lack of industry advocacy.
Black energy saving potential
Black energy saving potential, is already receiving worldwide attention.
90s of last century, the U.S. Department of Energy, Environmental Protection Agency, manufacturers, retailers, consumers and local governments jointly called the “Energy Star” energy-saving identification system, computers and appliances bear the brunt of black and white.
According to statistics, the United States, “Energy Star” program greatly reduces the resource consumption, only on the power-saving 80 billion kwh in 2001.
It is understood that EU countries will be required in 2000 TV standby power consumption of 6 watts to be below requirements in 2009, even down to 3 watts less.
In black energy efficiency in China has done a lot of work. According to the introduction of color TV to develop new energy efficiency standards, starting in March of this year, where more than 9 watts standby power consumption, energy efficiency index higher than 1.5, color TV, all can not enter the market.
Electric appliances, according to Shanghai Commercial Bank Association submitted the latest statistics, the current color TV social possession beyond 400 million units, and 15%% annual rate in the increase, the total energy consumption of TV has occupied the total power consumption of Chinese residents 10%%, but so far the market in sales of color TV, there are still more than 10%% of the products more than 9 watts standby power consumption.
According to reports, from March 1, 2005, China production, sale and import of household air conditioning and refrigerator paste these two appliances will be the first with the “China energy-efficiency labeling” on the label, to indicate their energy efficiency degree. So far, there is no black appliances labeled “China energy-efficiency labeling.”
Industry believes that energy conservation is not as black by the relevant standard of effective control, black energy problem is not enough of national and social importance. In fact, in recent years the rapid expansion of black markets, in 2000, China’s 800 million PC sales in 2006 reached 23 million units; In addition, the flat-panel TVs and home theater is also in every household. As the base of a huge, black electric energy savings must not be underestimated.
Mao Professor Yu Hai, said the one hand, fear of increased production costs as companies are unwilling to take in black electrical equipment energy saving technology; the other hand, there is no mandatory national standards require enterprises to be in the black products energy conservation measures .
Urgent popular
mature technology
Professor Mao said Technically, the black energy from Control audio and video output to proceed. Compared with white, black electric energy has become mature in technology, some developed countries, appliance manufacturers have been widely used black electrical energy-saving technologies. China, the world’s largest household appliance manufacturing, consumer, energy saving in the field of black consciousness in advance. This is for the improvement of household appliances market competitiveness of enterprises is also very beneficial.
Experts believe that use of Class D amplifiers and the LED backlight is the key to saving the black appliances. The main features black appliances is audio and video output. In fact, black appliances in the audio and video signal processing part of the power consumption low, while the power consumption is the highest part of the audio and video output section. Audio output is used for speaker audio power amplifier to provide sufficient brightness for the video display is backlit display. The two parts of the power saved, you can save a lot of energy.
