In order to analyze the relationship between meteorological elements and heating, the daily average air temperature, relative humidity, the wind speed and total daily solar radiation during the 2009 heating season in Beijing Meteorological Observatory are selected as the meteorological elements; the supply water temperature, return water temperature and difference between supply and return water temperature in the Beijing Haiyuan Heating Department are regarded as the heating temperature; and these factors are correlatively analyzed. The results show that the daily average temperatures and supplyreturn water temperatures have an obvious negative correlation. Their correlation coefficients are -0.75 and -0.62, respectively. The correlation coefficients between the daily average relative humidity and supplyreturn water temperatures are smaller, they are -0.41 and -0.47, respectively. and the correlation coefficients between the daily average wind speed and the above supplyreturn water temperatures are the least. In addition, the relationships between the various meteorological elements and supply water temperature, return water temperature and the difference between supply and return water temperature are analyzed. A table about the relationships between various meteorological elements and supply water temperature, return water temperature and difference between supply and return water temperature is set up. Based on the table of supplyreturn water temperature of daily average meteorological elements, the heating departments can directly control the supply heating under the different weather conditions and adjust supplyreturn water temperatures.
