Xiamen wall-mounted solar water heaters

The third stage of Xiamen hotels Solar water heaters school project, solar thermal and photovoltaic conversion to yellow will have more room for development, solar energy has become one of the major energy sources. Solar thermal have a broader and deeper development of the solar industry in the national economy has occupied a pivotal position. Technically, both concentrating collector or concentrator power generation has a extensive application. Of cold and cold areas including the northeast, north and northwest regions (referred to as the three northern regions), the annual average temperature is less than or equal to 5 ℃ half the number of days in more than 90 days, the longest Manzhouli up to 211 days, these areas habit the heating area is called, an area accounting for 70% of China's land area. In the residential building in the West Region, on the whole still accounts for the majority of bungalows and low-rise buildings, especially in rural areas, towns and small cities is also true. Bungalows and low-rise building envelope insulation levels in much the same conditions, the heat consumption indicators than the 10% -30% higher multi-storey buildings, some even higher. Wall-mounted solar water heaters Xiamen Xiamen wall-mounted solar water heaters in the heating zone, suburbs, small towns and rural construction in the whole society building in the proportion exceeds 70%, the annual hot water and heating in winter accounts for about 70 percent of the entire annual energy consumption According to the survey, Beijing rural households average three tons of coal, coal for heating in winter only reached 2.5 tons, 78% of households believe that heating burdens. According to current trends, by 2020 China's building energy consumption will reach 10.9 tons of standard memory. This is equivalent to 400 times the Beijing five reasonable power plant coal stocks. It is estimated that China's coal per ton according to the cost of electricity equivalent to approximately equal to 2700 ° electricity, so that by 2020 China's building energy consumption will reach 29430 ° electrical memory, even more than the Three Gorges power station generating capacity of 34 years combined. Providing green, clean, environmentally friendly, high-parity solar heating is the solution to our energy problems and to change the basic way energy mix. Xiamen wall-mounted solar water heaters
