The Overview Of The Development Of Flat Plate Solar Collectors At Home And Abroadpart Two
Early in 1970s, we had witnessed the development and the utilization of solar energy. Our country also had a huge impact in 1975. The first national solar energy utilization experience communication meeting held in Anyang, Henan Province, further promote the development of solar energy industry. The second session of the National Solar Energy Conference focused on the promotion and application of solar energy product in 1979. The World Conference on Environment and Development, in 1992, formulated the "China Agenda 21", which further defined in order to focus on the development of solar energy projects.
A "new energy and renewable energy development program" (1996-2010), developed by the State Planning Commission, the State Science and Technology Commission and the State Economic and Trade Commission, clearly showed us, during 1996 to 2010, the new energy and renewable energy development goals, tasks and countermeasures. However, the first Chinese shower room heating water by solar was built in 1958.
After 20 years of research and scientific and technological achievements, China's solar water heating technology has matured. With its safety, energy conservation, environmental protection and practical advantages, the solar water heater is loved by the majority of users. The solar water heater industry has become a new economic growth point in some areas.
According to the different types of heat transfer working fluid, the flat-plate solar collectors can be divided into air collector and liquid collectors. According to the operating rule of the absorber plate core, the material of the flat-plate can be divided into the iron pipe, copper, aluminum, mixing up by the copper and aluminum composite, stainless steel, plastic board and other non-metal collectors, etc. The type of pressing cover can be divided into single- or multi-layer glass, glass, steel or polymer transparent material, transparent cover plate collectors and other insulation materials. At present, the domestic market commonly used flat-plate collector and copper aluminum composite collector. The combination of copper and brass wings abroad generally use in high-frequency welding. China has also successfully developed a high-frequency welding copper collectors in 1995. From the mid-1980s, China and Canada introduced the aluminum composite production line. After a long-term digestion and absorption, it has now completed more than ten domestic aluminum composite production lines.
In order to improve the absorption of solar energy, the scientists reduce the loss of the collector heat and improve the overall efficiency of the collector. Solar collectors pieces (commonly known as the board core), especially board core, are used with selective solar absorber coatings last for many years, which has achieved very good results. Now, China has been able to produce high-performance TiNO series of selective photothermolysis absorbing coating that is made of a special plastic materials as raw material. In addition, in order to overcome the common flat-plate solar collector shortcomings, it is important to utilize the heat pipe flat plate solar collectors and water heaters. The test results show that the heat from the one-way heat pipe transfered to different characteristics of the system greatly reduces the heat loss through the collector. It has the practical value of the heat pipe flat plate solar collector on large-scale centralized heating, which is very meaningful.
In efficient coating, with the high transmittance cover, seal insulation and other high-tech support, a large number of excellent flat-plate collector products such as modular solar collector, heat pipe solar collector and water heaters, etc. are produced, which flat plate solar collector and its further development played a great role in promoting.
