Core Tip: one to the winter, they nervous, tired, "Every company is difficult to see, almost all went to the site maintenance."
"Flat Solar Energy Collector is optimized for pressure systems and solar collectors secondary circulatory system, while integrating with the building, with easy to integrate with the building facade, ease of installation operation and maintenance, long life and other advantages, vigorously promote the practical Flat solar water heater is narrowing the gap with the international advanced level in an important way. "
? "Renewable Energy Technology and Industrial Development "Reader, the Chinese Government / World Bank / GEF China Renewable Energy Scale-up Program (CRESP) Project published the results published in the editorial board in April 2009
A Guangdong government officials in Beijing after the meeting to end, brought back a "renewable energy technology and industrial development," Reader, then he turn donated to the Hu Guangliang.
As chairman of the Guangdong Fivestar Solar Energy Co., Hu Guangliang treasured, he insisted the 20-year career?? The development of China's flat panel solar water heater, finally got through in this way the recognition and certain third-party authority.
Many friends more than once Huguang Liang said: If you do other industries, certainly got a bad hair than now.
Strange "water heaters in China phenomenon"
Present, China's solar water heaters are mainly two types: vacuum tube solar water heaters and flat-type water heater. Which, vacuum tube-type water heaters account for over 90% market share.
This, the international peer-nicknamed the "water heaters in China phenomenon." Because, in the global context with a vacuum-type based only our country. France, Italy, Germany, Spain and other European countries are dominated by flat-panel, Japan is. Portugal, Israel, Greece, Brazil and other countries is close to 100% of flat products.
With urban development process have mushroomed in the multi-and high-rise building, on the vacuum tube solar water heater installation and use of a challenge. As the multi-storey buildings and high-rise buildings is not enough roof area, terrace-style should be adopted or the south wall of the solar water heater. Easily broken vacuum tube, Sealing Ring aging easily leak, to terrace or a large wall installation of security risks. In Beijing, a leading solar energy company's management had already complained to reporters in private, one to the winter, they nervous, tired, "Every company is difficult to see, almost all went to the site maintenance."
The flow with copper pipe, cover with glass plate produced by solar collectors, can load 1500 kg, the whole system safe and reliable components, combined with a higher degree of construction, especially suitable for installation on balconies and external wall construction, so that "breaches" of solar water heater to enter a "safe" era. System is designed for flat-panel solar water heater pressure, constant pressure, water pressure, water large bath give people more happy, and the resistance to corrosion, no scale, clean and cater to the urban living style, will Yu Lai The more loved by consumers, thereby promoting the solar energy industry, the process of urbanization.
China Rural Energy Industry Association Professional Committee Luo Zhentao solar energy utilization in the analysis of the foreign application to flat panel solar water heater, said the main reason: flat plate solar water heater under pressure, long life, easy to form secondary loop system; In addition, it easily and Architecture combination, easy to install, easy to design architect; 3 is the system secure.
Luozhen Tao said, the last two years, China's flat panel solar water heater with an increase of 46% of the development speed increase. "Flat water heater is particularly suitable for Project Use, many provinces and cities nationwide are now preparing for more than 10,000 square meters of engineering, there is a 40 000 square meters of Shandong, and are ready to choose to use flat solar water heaters. "
New Flat-round performance to win Since the flat-type solar water heater
better, then why only our vacuum products as well as absolutely mainstream?
"In contrast, vacuum tube solar water heater manufacturers now there is no threshold." One who deeply understands the industry, "in some places, some people buy vacuum tube solar water heater parts, an assembly of the Na Qu sell, but how the quality of follow-up technical support, equipment maintenance how, depends on the purchaser's luck. "He believes that the market does have" chaos. "
The regular large-scale solar water heater with vacuum tube products manufacturer based products, it is caused by historical reasons. 80-90 years of last century, when China's first use of natural circulation type solar water heater plate temperature required more than 0 , compared with tube-type minus about 10 in the work, did some limitations. Although performance is concerned, there are many advantages of flat, but the fatal wound makes it impossible to enter the country, so that a larger vacuum tube-based development. Then further reduce the cost of vacuum tube-based, consumer demand is not high, making manufacturers more willing to produce and promote the products.
"But the feeling from the actual use, the vacuum tube type is always 'Can' areas not yet reached 'useful'." There are not to be named told reporters the industry, because of its vacuum tube type For cost reasons, generally a non-bearing water tank, so when hot and cold, the phenomenon of flow instability, and general water quality of water for the second category.
"Once the flat-type solar water heater and antifreeze using the secondary circulatory system, a good solution to the problem of low temperature operation after the completion of its advantages is exhaustive." Huguang Liang told reporters, five-star director of research and development R & D in winter in person with The new efficient flat plate solar water heaters, and vacuum tube solar water heater do contrast the northern tip of China Mohe went to extreme low temperature environment test, at minus 40 , the plate product is still working well and stable output of hot water, and even members of the local experimental admired. The vacuum tube type has burst.
's Hand with a flat plate and vacuum tube-based comparative table full range of product performance. Total includes safe, durable, and architecture combine performance, collector efficiency, health and comfort, product life, cost and other major items of 6 ~ 16 items, flat panel product is a comprehensive win. For instance, flat products "machine no wearing parts, service life of up to 25 years," tube-type products, "the average life of 8 years or so," and so on. Government became the largest salesman
When the star has invested heavily in flat products in the core technology research and development, ultimately made significant technological breakthrough, I am China Manufacturers writer, reports some information about clarion marine audio , nostalgic record player.
