Simple Calculation for Design of Solar Water Heating System Based on Excel Sheet
Solar energy,as a kind of renewable green energy source has been widely utilized in solar water heating systems in China.But the design calculation of the solar water heating system is more complicated than the other of water heating systems,especially the calculation of solar collector installation spacing and solar collector area is more cumbersome.According to the engineering practice,the calculation of solar collector installation spacing and solar collector area was analyzed,and a quick and simple calculation method based on Excel sheet was presented,which can save the calculation time and reduce mistakes and omissions for reference to the designers.
