摘要
太阳能开水器以电作为补充能源进行开水供应。本文利用动态的年计算费用法将这种供应形式与电开水器进行了比较。经计算,在长春地区按7月份平均的太阳辐射强度确定出的集热器面积使太阳能开水器年费用最小,与开水供应量相同的电开水器相比,其回收年限为4.1年。从经济性方面来看,这种开水供应形式在长春地区使用是可行的,经济效益比较可观,在全国大部分地区都有推广价值。
The solar energy boiled water tank supplies boiled water by means of using electricity as supplementary energy source. This paper compares this form of supply with electrical boiled water tank by using dynamic annual computation cost. After computation, we know that the cost of solar energy boiled water tank is the least in Changchun District when we determine the area of collector according to the average intensity of solar radiation in April. Compared with electrical boiled water tank with the same supplying amount of boiled water, its payback period is 4. 1 years. In terms of its economy, this form of supplying boiled water is practical in Changchun District. It can be spread in most areas of our country.
