Solar water heaters school Zaozhuang hotel project

Zaozhuang hotels heaters Solar Engineering School of the cold and cold regions include the Northeast, North and Northwest (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 up to Manzhouli 211 days, these areas are customarily referred to heating area, 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 buildings in the building envelope insulation levels in much the same hotel Zaozhuang solar water heater school project conditions, the heat consumption indicators than the multi-story building is 10% -30%, some even higher. Solar water heaters school Zaozhuang hotel projects in heating area, suburbs, small towns and rural buildings occupied buildings in the whole society accounted for more than 70% of 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 warm 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.
