The standby power consumption of such LCD TVs adopting the new light perception and frequency conversion technology can be decreased below 0.1W; the wear rate of a washing machine with the function of "stop as soon as cleaning is over" can be reduced about 25 percent than that of common washing machines, and can save 30 percent water and electricity respectively; the multi-door frequency conversion refrigerator adopting the advanced dual refrigerating cycle system can realize refrigeration directly through a refrigerating evaporators or a freezing evaporator, effectively reducing the power consumption and realizing super energy conservation...
In the household appliance zone in various supermarkets and shopping mall, we can see these energy-conservation household appliances with various types. Nowadays, people's living standard is increasingly improved, and household appliances have been the necessities in people's daily life. As people have experienced such energy crises as "switch off to restrict electricity use", "gas oil shortage" and "soaring petroleum gas price", energy conservation and environmental protection has become people's first demand on the function of household appliances.
In August 2004, National Development and Reform Commission and General Administration of Quality Supervision, Inspection and Quarantine of P.R.C. issued Regulation on Energy Efficiency Mark Management to conduct unified energy efficiency mark system on such energy consumption products with a large energy consumption potential and wide use. Starting from March 1st, 2005, the government began to implement compulsive energy efficiency mark system on such two products as refrigerators and air conditioners. In September 2006, the second batch product content about energy efficiency mark implementation was issued, where the electric washing machine and unitary air conditioners are listed. Starting from June 1st, 2008, the new energy conservation standards on such five-type house appliances as gas water heaters, electrical storage water heaters, induction cookers, multi-connected air conditioning (heat pump) units and frequency conversion air conditioners had been implemented successively.
However, the fundamental key to solve the energy conservation issue of household appliances is to innovate and make breakthrough on the energy conservation technology of household appliances. With the extruding problem of product homogeneity and increasingly fierce market competition, many household appliance manufacturers realized that only to establish the core competitiveness based on the investment and development of new technologies and new products, can they find the market breakthrough and realize enterprises' sustainable development. Consumers realize that to purchase such energy conservation household appliances with new technologies cannot only generate economic benefit, but also nurture a healthy and environment-friendly living style.
In order to put household appliance energy conservation into place, manufacturers invest more energy and scientific research on developing such products with energy conservation, power saving and low consumption, and turn their eyes on the new technology application to improve energy conservation effect. Through technology innovation, they can find a new market on the layer a little higher than the current market, innovate in the market-demanded products, culture and create such a potential future market, and increasingly develop such forward-looking products with high-tech content. For the moment, the energy conservation products have made new breakthroughs in various fields of the household appliance industry. In terms of air conditioners, such a type with direct current and frequency conversion is becoming the mainstream in the market step by step; in terms of refrigerators, consumers do not only require frequency conversion, their requirements on the compressor efficiency has also been enhanced rapidly; in terms of washing machines, with the performance of energy conservation and water saving, rolling washing machines have caught higher and higher market shares; in terms of water heaters, some products with new technologies, such as solar water heaters and heat pump water heaters, are being favored by consumers increasingly.
Through persistent technological innovation, various large household appliance manufacturers developed novel products with higher energy efficiency continuously. It has not only made profits for these manufacturers, but also helped consumers save energy expenditure and reduce the energy consumption of the household appliances. The hot selling of energy conservation household appliances has created a new development space and injected new vigor into household appliance industry after the over-10-year rapid development of the industry.
