Abstract

The model for calculating the water-mass-to-collector-area ratio (the ratio is abbreviated as MAR) was developed based on the useful energy output model of a flat-plate solar collector. The MARs were calculated by using the typical meteorological data of seven cities in Yunnan Province. The final water temperature of the water tank is assumed to be 60 during the calculation. The ranges of MARs have been given for seasonal or year-round running of the flat-plate solar water heating system. For convenient engineering applications, the quadratic fit equations between MARs and tilt angles have been obtained with high correlations (R2>0.999). Further discussions found that the optimal tilt angles and the corresponding MARs for spring, summer, autumn, winter or year-round operation of the solar water heating system are respectively in 10 ~ 15o, 0 ~ 0o, 32 ~ 38o, 45 ~ 50o, 24 ~ 30o, 50 ~ 60 kg/m2, 44 ~ 51 kg/m2, 43 ~ 56 kg/m2, 44 ~ 58 kg/m2 and 46 ~ 52kg/m2.
