Materials technology for the home appliance industry on the development of new ideas

"After the financial crisis period, the home appliance industry should strive to achieve industry transformation and upgrading to the next round of economic growth in developing a solid competitive strength. "Electrical appliances Association President Jiang Feng in 2010 China's home appliance technology so that the General Assembly.

And in the Technical Conference of journalists see, domestic electrical appliance enterprises, scientific research institutes in household appliances related materials technology research and product innovation, never let up. This technology conference presentation materials involved in a wide range, including magnetic refrigeration materials, engineering plastic, copper alloy, environmentally friendly polyurethane foam and; both forward-looking technology development trend, there is already a practical technology maturation, for the household appliance industry technology upgrade, product innovation opens up completely new development ideas.

As global environmental problems of an increasingly grim, as well as the Montreal Protocol and the Kyoto Protocol's dual regulated, global refrigeration industry is trying to find alternative to HCFC substances environmentally friendly refrigerant. While this technology Conference, Beijing University of technology of Prof. Liudan magnetic refrigeration materials described as refrigerant instead of opening a new route.

Magnetic refrigeration is a magnetic material as refrigerants in refrigeration technology. Magnetic refrigerants are magnetized magnetic entropy decreasing heat to the outside world; weakened when the magnetic field, the magnetic entropy increase, magnetic refrigerant heat absorption from the outside world. According to Prof. Liudan, compared with traditional refrigeration technology, magnetic refrigeration with high efficiency, pollution-free, low energy consumption, safety and reliability advantages; refrigeration efficiency can reach the Carnot cycle of 30 ~ 60%, the COP value can reach 10.

At present, magnetic refrigeration is still belongs to the leading-edge technology, suitable for magnetic refrigeration materials for magnetic refrigeration test machine is still under development, but the traditional concept of refrigeration for the refrigeration industry is not only the development of reference, more enterprises to bring the new development space and opportunity.

Xingrong gaoke introduced a savings of 80% copper and performance excellent copper-aluminum composite pipe (ACC) technology. ACC tube outside to the inside of a rust-proof aluminum alloy, as oxygen-free copper, it is a good moment of the copper heat absorption capacity and good heat dissipation of aluminum capacity combined with excellent heat transfer performance. ACC with inner thread pipe manufacturing of air conditioners, energy efficiency ratio than inner-grooved copper tube high 0 ~ 5%; at the same time eliminate the traditional air conditioning copper tubes and aluminum fins of electrochemical corrosion, air-condition life cycle energy efficiency than the slow decay.

According to xingrong gaoke Li Sheng, after a air conditioning company abroad for a year and a half of demanding inspection, its headquarters approval in 4 models with ACC pipe replace inner-grooved copper tubes, and obtained the refrigeration energy efficiency ratio (EER) improve 3.2%, heating energy efficiency ratio (EER) increased 4%, are currently batch quantity purchase stage. To date, more than 100 air conditioning and auxiliary plant is copper-aluminum composite pipe application validation work. June 2010, use the ACC manufacture of all types of a/c number has reached millions of Taiwan and exported to overseas market.

To achieve China's household electrical appliance industry from big to strong changes, this involves the home appliance industry the whole industry chain's adjustment. And home appliance products supporting upstream materials technology innovation and upgrading is an indispensable part of the key.

To this end, the electrical appliances Association Vice President Wang Lei, said, we need to progress through technology to improve product quality level of technology, but also requires the adoption of technical progress to achieve the upgrading of the product; from networking, MEMS technology, new materials development for the household appliance industry provides limitless imagination of innovation and progress in space.
