摘　　要：涡旋压缩机是空调行业的常用设备,通过变频驱动运转,可在部分负荷下更安全节能地运行。为得到适用于空调节能运行的智能控制数学模型,基于稳态工况假设得到简化的一次线性、三次多项式和二次指数等模型。在三种工况下进行了压缩机的变负荷实验研究,利用实验数据对三种数学模型进行了回归分析,平均相对误差分别是2.0%、1.7%和1.8%。对于空调用涡旋压缩机的数学模型,考虑复杂性和精确度两个因素,一次线性模型的平均相对误差≤2%,满足空调节能运行智能控制的精度要求。The scroll compressors are widely used in the air-conditioning industry. Driven by frequency converters under the partial load, the compressor will work in a safer and more energy-savingway. In order to get the mathematical model suitable for energy conservation in air-conditioning intelligent operation, the linear model, cubic polynomial model and quadratic exponential model were simplified based on the steady conditions. Three conditions of the variable load were experimentally studied. The experimental data of the three models were regressive analyzed. The average relative errors are 2.0%, 1.7% and 1.8% respectively. The average relative error of the linear model is no more than 2.0%, and it can meet the accuracy requirements of energy conservation in air-conditioning intelligent operation when the complexity and accuracy of the mathematical model of the scroll compressor are considered simultaneously.
