In winter, solar water heater industry is also used to regulate.
In winter, the most comfortable thing is to have a hot shower, but many solar water heaters have been hit by water heaters. Solar water heater using the Chinese consumer society groups according to the survey: 40.87% of the solar water heater will not be able to use one to winter, about 60% of the solar energy water heater heat enough water or water shortage in winter.
"Winter is good" is becoming the "threshold" for solar water heater industry. How to promote the industry to standardize, how to innovate the technology application to meet the consumer demand, become the common problem in the industry.
Every link can become the bottleneck of solar water heater in winter. The vacuum tubes produced by some small manufacturers are of poor quality and small specifications, leading to low thermal efficiency of hot water production system. Or the whole machine anti-freeze ability is poor, such as the water tank insulation effect is poor, the hot water cannot keep warm, the pipeline is frozen, the hot water circulation is not smooth; Or partial solar water heater installation is not standard.
Himin solar energy co., LTD. Technology research and development center director Zhang Lifeng thinks, solar water heater is a systems engineering, "" winter with" should have a good host, more want to have a series of accessories and the good match the system installation. In this sense, solar water heater is not accurate, should be called "solar water system."
"Winter is not hot" also reflects the lack of standard constraints on the development of the solar industry, and the state has taken note of this situation. According to China's agricultural energy solar energy heat utilization industry association, director of the professional committee Luo Zhentao revealed that 2009 project was developed jointly by the state department of sixteen of the solar energy water heater efficiency levels of national standard has passed the examination and approval. "If implemented, it would be a binding standard that the industry must follow."
The first solar water heater was born in China in 1978, and in 2004, our country's vacuum tube solar products went abroad. After more than 20 years of efforts, China's solar industry get rapid development, gradually formed Beijing, eastern, taian, yangzhou, haining five industrial base, and the surrounding radiation, capacity increase rapidly. Luo Zhentao live to our reporter listed a set of data: in 2010, China's solar water heater production has reached 49 million square meters, the whole industry 2010 annual output value reached 73.5 billion yuan, increased by 22.5% than in 2009.
Although it belongs to the high-tech and new energy industry, the state also emphasizes the elimination of backward and industrial upgrading in the 12th five-year plan of solar energy industry. "" twelfth five-year" period, we should strive to develop three types of enterprises, the first is to cultivate 5 to 10 with independent intellectual property rights, with international competitiveness, the annual output of about 4 million square meters of large-scale backbone enterprises; The second category is excellent supporting enterprises; The third category is engineering implementation enterprises, including construction, sales and after-sales service, a total of a dozen large enterprises. "Said luo.
As the leading brand of solar energy industry, huang Ming has completely eliminated 180cm and the following specifications of the heat pipe water heater. They are now applying the 400 degree solar thermal power generation technology at the highest level in the world to the ordinary domestic hot water system, and developed the "gold product hot water machine" series products. "We did a test, taking the Beijing winter as an example, using the newly developed solar hot water system, using only 2 percent of the auxiliary energy for the winter. It is not impossible to use solar water heater in winter, but it must solve the problems such as heat collection, heat preservation, pipeline transmission and anti-freeze of the whole machine. "Zhang said.
