Solar water heater technology to expand the heating area
[REVIEW] the beginning of the solar water heater industry concern. In 2009, after successful participation in activities of home appliances, industry ushered in a great development, but we also see that many manufacturers of product homogeneity, low barriers to entry, low-technology, has constrained the development of the industry to engage in healthy the bottleneck. Recently, the China Rural Energy Industry Association Professional Committee of solar thermal and Professor Luo Zhentao Professional Committee of China Energy Conservation Association, solar Secretary Huozhi Chen, Professor, reporters interviewed, as we explain in detail the solar thermal industry development, the industry concerned by the current status of development of the industry will have a clearer understanding.

Reporter: solar water heater in the \"home appliances\" in two bid, please tell us about the development of solar water heater?
Luo Zhentao: Recently, we have 36 solar water heaters for the first half of the marketing conditions were investigated. 36 enterprises surveyed can be divided into two categories: 12 key enterprises, compared to last year, two flat, but quantities are increased; remaining 20% ??growth 10 to 60%; 12 average an increase of 32.6%. The second category of medium-sized enterprises, a total of 24 survey, distributed in eight provinces. There are two negative growth (-20% ~ -30%), a flat, two less than 6% growth, and the remaining 19 increased 20% to 70%, which increased 100% in Sichuan over two, 24 average an increase of 37.25%.
The survey results indicate that the overall economic development impact of solar water heater industry was sustained and stable development trend. This is why we write the country\\ s new energy industry development, \"second five\" and long-term planning proposals the basic starting point.
At present, solar water heater is facing a major adjustment of industrial structure, its one of the adjustment is to develop large enterprise, improve industrial concentration, the promotion of famous brands. 2000 years ago, twenty strong corporate concentration less than 20.5%, up to 45% today, a few years to reach 60% to 70%. This is the normal law, but also a sign of the industry toward standardization. Number of low-level small business lies in restructuring or turning, can not always stay in the primitive stage, we must upgrade, or must be eliminated.
Reporter: Solar water heaters are low-temperature solar thermal utilization, production is now out in the temperature vacuum tube collector, solar water heater is not a description of industrial upgrading?
Huozhi Chen: Yes, solar water heater in the early stages of industrial upgrading. Achieve industrial upgrading and technological progress and a few marked expansion of application fields, solar water heaters are now several companies have launched their own R & D results, marking the area of ??solar water heater industry forward extended heating applications. Among them, the all-glass vacuum solar collectors in the temperature has passed appraisal and acceptance, Norit 150 ? vacuum collector tube efficiency as high as 45% or more; Emperor Ming in the temperature of 128 ? tube also through project acceptance. The development of medium-temperature collectors for air conditioning, desalination, industrial use of technology and equipment to provide efficient collector.
400 ~ 450 ? high temperature solar collector and solar collector technology application and development of thermal power generation will provide key technologies and products, Wong Ming Marino new materials company and the company\\ s 400 ?, 4-meter-long vacuum tube samples have been successfully developed, will the formation of production capacity; Pete\\ s 350 ?, 2-meter-long vacuum tube has 260 kilowatts of thermal power plant applications. China\\ s first 50 kilowatts of thermal power station argument.
Expansion of the field of solar thermal development of the major trends. Some companies have enjoyed applications development results. Industrial and agricultural production, such as with hot water is an important area of ??application, Shaoxing, Zhejiang, Xiaoshan dyeing of 50,000 square meters 16,000 square meters of flat-plate collector hot water works; Jiangsu Changshu Qaeda and dyeing of 15000 East square meters of vacuum tube solar hot water project, the initial implementation of heat metering and energy contract management; Inner Mongolia Yili company also produced in the use of . Vacuum is the efficient electrical auxiliary energy, 24×7 intelligent control hot water system development, the proportion of products in 2010 reached 40%.
