据有关资料统计,我国建筑使用期耗能占全国耗能的17.66%,其中主要能耗是生活用煤,包括采暖、厨房炊事等。近几年来,城乡建筑的大量兴建,用于采暖的燃料猛增,供应不足。因此,节约采暖常规燃料,开发利用新能源非常必要。我国地处北纬4°～52°32′,有丰富的太阳能资源。如北京市,年太阳辐射量为130千卡/厘米~2,年日照时数2600～2800小时。利用太阳能采暖,即通过各种途径使建筑物尽可能多吸收并储存太阳热能,保持和提高室内所需要的温度,是一种现实而有效的方法。所谓太阳能 According to related statistics, China’s building energy consumption during the period of use accounted for 17.66% of the country’s energy consumption, of which the main energy consumption is the life of coal, including heating, kitchen cooking and so on. In recent years, a large number of urban and rural buildings have been constructed, fuel for heating has soared, and supply is insufficient. Therefore, it is necessary to save heating conventional fuels and develop new energy sources. Our country is located at 4° to 52°32’ north latitude and is rich in solar energy resources. Such as Beijing, the annual solar radiation is 130 kcal/cm~2, and the annual sunshine hours are 2600~2800 hours. The use of solar heating, which means that buildings absorb and store solar energy as much as possible through various means, is a practical and effective method to maintain and increase the required temperature in the room.
