中文摘要：

为降低空调系统的运行成本，提高其运行的经济性，提出了一种新的用于空调系统热经济性分析的评价模型。该模型是在热力学的煅分析和经济学等理论的基础上形成的，并以能量费用和非能量费用计算的单位热经济学成本作为分析评价的依据。通过2因素3位级9个工况的正交实验，得到用该模型计算的单位热经济学成本曲线，并同热经济学矩阵模式分析方法的计算结果进行了比较，结果表明该模型是合理的，可为空调系统的经济运行状态诊断提供决策依据。

英文摘要：

The operation cost of air conditioning systems can be reduced to increase their economy. By analyzing all the components of an air conditioning system, a novel evaluation model of thermoeconomic analysis in the air conditioning system is presented. The model is based on thermoeconomic analysis, i.e. thermodynamics and .economics, etc. All the unit thermoeconomic costs can be obtained by using the model with fuel, product and non-energy cost. Through crisscross experiment, which concludes 9 conditions at operation according to the 2-factor and 3-level table, the comparison curves of the unit thermoeconomic costs between the model and thermoeconomic matrix mode are obtained. It shows that the evaluation model based on the unit thermoeconomic costs is reasonable, which can provide the decision-making direction in economy operation diagnosis of air conditioning systems.
