空调系统能耗特征曲线研究及应用
Research and application of energy consumption characteristic curve of air conditioning systems
摘要：
对空调系统逐日能耗随日均温度的变化规律进行了研究，引入参数化的Sigmoid函数，将其定义为空调系统能耗特征函数，对逐日空调系统能耗规律特征进行了参数表达，定义了2个影响空调系统能耗的特征值。使用Sigmoid函数对逐日空调系统能耗数据进行了拟合，拟合效果较好，该函数可对逐日空调系统能耗随日均温度的变化规律进行较精准的表达。提出了一种基于空调系统能耗特征曲线的新型空调系统能耗评估方法，并给出了应用举例。该能耗评估方法比传统能耗评估方法可以更客观、更准确地对建筑空调系统能耗进行有效评估，可用于指导系统节能运行、优化改造。
Abstract：
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.
