Solar water heater in the end belongs to what industry, which belongs to the specific interpretation of the industry
Due to the existence of low efficiency, fast heat dissipation, less water, winter can not be used, and other shortcomings, has now withdrawn from the market. Twentieth Century 80 - 90s, under the support and leadership of the relevant departments of the State Council, the Beijing Solar Energy Research Institute began to engage in the study of solar thermal utilization, the early development of flat solar water heaters. In 1984, the Tsinghua University invented "magnetron sputtering aluminum / aluminum nitrogen gradient solar selective absorbing coating, the solar mass production and commercialization of applications possible, directly spawned by Chinese solar thermal industry, the vacuum tube type solar water heater is suitable for Chinese situation of main products. Since twenty-first Century, China's solar water heater has entered a mature stage, output and market share has maintained rapid growth. According to the "solar thermal utilization Chinese Industry Development Research Report (2008-2010)", in 2009 the water heater annual output of 42 million square meters, an increase of 35.5%, of which 40 million square meters for the vacuum tube collector, accounting for about 95% of the social population reached 145 million square meters, an increase of 16%, energy saving of about 21 million 750 thousand tons of standard coal, carbon dioxide emissions about 60 million tons
Name: solar water heater English Name: solar water heater definition 1: the conversion of solar energy into heat energy to achieve the purpose of heating water. Applied disciplines: power (Level 1); renewable energy (level two) definition 2: devices that absorb solar radiation to heat water. Subject: application of science and technology resources (a subject); energy resources (two subjects) 70-80 in twentieth Century, due to the national economic development is backward, people's life level is low, many residents use stuffy type water heater (gasoline bucket type and tank type automobile etc.)
Water heater 2009 annual output of 42 million square meters, an increase of 35.5%, of which 40 million square meters for the vacuum tube collector, accounting for about 95% of the social population reached 145 million square meters, an increase of 16%, energy saving of about 21 million 750 thousand tons of standard coal, carbon dioxide emissions of about 60 million tons. 2009 solar water heater production accounted for 78% of the world, accounting for the world's total of 54%. The total output of 2010 Chinese solar water heater industry reached 49 million square meters. In China more than 95% of the products for all glass vacuum tube solar water heater. The solar water heater industry is a specialized industry, has been basically formed from the technical research and development, product design, raw material processing, equipment manufacturing, production, testing and certification, engineering design and marketing services to the industrial system, led to the development of glass, metal, insulation materials, machinery manufacturing, logistics and other related industries.
