Studies the change law of daily energy consumption of air conditioning systems with the average daily temperature. Introduces the parameterized Sigmoid function as the energy consumption characteristic function of air conditioning systems. Expresses the daily energy consumption characteristics of air conditioning systems by parameters. Defines two characteristic values that affect the energy consumption of air conditioning systems. The Sigmoid function is used to fit the daily air conditioning system energy consumption data, and the fitting effect is good. This function can perfectly express the change law of daily air conditioning system energy consumption with average daily temperature. Proposes a new air conditioning system energy consumption assessment method based on the energy consumption characteristic curve of air conditioning system, and presents an application example. This new energy consumption assessment method can effectively evaluate the energy consumption of building air conditioning systems more objectively and accurately than the traditional assessment method, and is of help in guiding the energy-saving operation of the system and optimization transformation.
