In this paper, a prediction method about central heating parameters based on method of least square is proposed. First, according to the theory of heating operation adjustment, the advised heat is determined; then, the method of least square is used to seek the mapping relationship among the outdoor temperature, system flow, supplying and returning water temperature, etc. The method achieved higher prediction accuracy, and energy-saving effect is remarkable.Keywords-heat load; parameter identification; air temperature daily variation; method of least square.
