Obama cited China\\ s solar technology research attention

      U.S. President Barack Obama Beijing at 10:00 on January 26 State of the Union in Congress. Throughout his speech, Obama mentioned four times in China, India and other rapidly developing controls, that the crisis facing the United States competitive. Obama said: \"Some countries, such as China and India, they have realized that only by change order in the world, invincible, so they began working as soon as possible to educate the children, and extended education time, more emphasis on math and science. Just recently, China has the world\\ s largest private solar energy research institute. \"

In recent years, rapid development of China\\ s solar industry, solar energy production are taking advantage of scale in the world. In 2010, domestic production of vacuum coating machines with 2,000 units, more than 400 million sticks vacuum tube production, the actual use of 368 million, the annual total production of water heaters, 49 million square meters, an increase of 16.7%. Solar collectors in 2009, ownership is 1.45 million square meters, the actual usage in 2010 is 168 million square meters, an increase of 15.9%; value of 73.5 billion, an increase of 22.5%, ranking first in the world scale. At the same time, with Norit, Wong Ming business investment in R & D continued to increase domestic solar technology research also began to cut outcrop angle, and gradually catch up with international advanced level. Especially led Norit and building integrated solar technologies and solar energy in high temperature technology, has reached the world\\ s leading technology, Norit 2010, only to get five major national invention patent. Over the years, Norit active with the University of Stuttgart, Germany, Tsinghua University, Shanghai Jiaotong University, Shandong University and other famous universities building cooperative technical research. Norit which established cooperation with Tsinghua University, Institute of Optoelectronics, developed into a total and the temperature and the collector, the collector temperature of 150 ?, to fill the international blank, the success of the and refrigeration, desalination , dyeing, textile and other industrial and agricultural production to provide technical support for solar applications.

is not a clean small country?

Recently, the area who lives overseas Greentown area Jianxi Ms. Yang and Ms. Wang said, his home water heater, Sheung Shui, time is getting short, a smaller amount of water, the water does not look clean, it is Editor\\ s Note ?

Hot days, and gradually increase the frequency of use, along with some of the problems can also enable the public to worry about endless. Recently, the area who lives overseas Greentown area Jianxi Ms. Yang and Ms. Wang said, his home water heater, Sheung Shui, time is getting short, a smaller amount of water, the water does not look clean, it is Editor\\ s Note ?

Clean out a lot of scale

Reporters follow a solar water heater repair company managers and Master Huang Ping Yingjie to go see. Feng Yingjie in the roof, after some checking, smiled and said: \"The solar water heater in your house \\ bath\\ it!\"

Water heaters as well as \"bath\"? Ms. Yang, Wang revealed the surprising look.

Master Huang smiled and said nothing. I saw one by one, he carefully put down the vacuum tube removed, the inside of the water poured out, and washed repeatedly with water. Glass cleaned, turn the water tank. Fengjing Li and yellow together to hold the master tank, so rocking back and forth, inside the water from the nozzle flow. This reporter saw tanks from inside the glass tube and the water muddy bear out, mingled with large scale.

Finally, clear out a full scale can hold more than half of washbasin. \"Is the scale occupied the position of the tank, water tank filled with water less, and sometimes not on the full.\" Master Huang said. Slowly, over clear scale, the water inside the tank has become clear the.

Usually have to wash with 3 years

How is there so much water heater inside the scale it?

Feng Yingjie has been engaged in solar water heater repair five years, he said, the water is relatively hard Luoyang (the city\\ s main drinking water is groundwater, mineral content), a long time, the natural scale inside the tank piled up. Scale than the two things occur:

First, plug the vent. Feng Yingjie said vent in the bottom or top of the tank, the role is to balance the pressure difference between inside and outside the tank, once blocked, the internal heat can not be discharged, will be increasing pressure, the tank will be broken up. \"For almost a tank around $ 600, better and more expensive, we replaced this year has given dozens of tanks up.\" Ping Yingjie said.

Second, more scale, the less water it. \"Originally basin of water can hold 5, now only hold 3 basin of water. The shower water naturally smaller.\" Ping Yingjie said.

Feng Yingjie said that in general the solar water heater with 3 years, you need to clean the scale, and this can also extend the life of water heaters. Cleaning prices, according to the size of the solar water heater is slightly different, for 60 yuan to 90 yuan.

    Since November 2010, the domestic leader in the first to open a \"technical innovation-driven product upgrades,\" the new industrial revolution. Four Seasons Mu-song set off from the domestic market penetration of solar water heater automatic big behind the scenes, re-leveraging \"of things\" intelligent sensor control technology, introduced a new solar water heater things. Meanwhile, Sang Le, brilliant, Hua Yang and other companies also have automatic force of solar water heaters.

    Marino, Emperor Ming, Sun Yu and other enterprises in the overall layout of the high-temperature solar water heaters. Compared with ordinary water heater, the temperature control products for industrial production. At present, the first solar thermal power generation projects have been landing in Beijing, the Ming emperor to become an important technology partner. The Marino\\ s high temperature pipe technology and technological achievements in the completion of project identification, the successful sale. Sun Bao health technology is the solar force, launched China\\ s first solar UV sterilization of health products, is expected to set off in 2011 domestic solar thermal industry, the health revolution.

    In addition, there are many companies in order to promote industrial upgrading of space, but also to the main solar thermal, heat pump auxiliary air support for multi-product integration of energy technology products. Tongji sun, Haier, especially steven, Manpower and other enterprises have the layout of the air heat pump water heater, in order to achieve the integration of industry-style development.

    In this regard, Lessons also believes that \"In the past two years, many companies compete for market share around the development is very impulsive, the expense of investment in product innovation this year has been a large number of leading companies have turned to product innovation, intended to upgrade the product generation to promote and stimulate new markets which will benefit the industry\\ s future development and growth. \"
