摘　　要：针对制冷和制热两种情况,建立了以稳态仿真为基础的空调数字化仿真系统。首先运用新的制冷剂显式快速计算模型,对制冷剂物性计算程序进行完善。然后采用集中参数法建立了压缩机模型,对压缩机的性能参数进行二元十项的拟合回归。对毛细管建立了均相流分布参数模型,并且针对该计算模型提出了新的无量纲关联式。在部件模型基础上,建立了家用空调系统仿真计算模型,并且对以往的迭代算法进行了改进,提高了系统稳态仿真算法的稳定性。在系统数值模型的基础上,完成了完全面向对象方式的空调器数字化仿真软件。该仿真结果与实验数据吻合较好,软件可有效预测空调器的性能参数。For both refrigeration and heating cases, proposes an air - conditioning digital analysis system which is based on steady simulation. Firstly, the explicit and fast - calculation method has been presented, which improves the calculation program for the refrigerant thermal properties. Secondly, the compressor model is established on lumped parameter method performance parameters of compressors is fitting regressed through binary decathlon form. A numerical model of capillary is proposed based on the homogeneous flow distributed parameters model, then a new dimensionless correlation formula for the capillary simulation is proposed. Based on the component model, an air - conditioning simulation system is proposed, and improve the previous iterative algorithm to improve the stability of system simulation algorithm. Based on the system numerical model, an air - conditioning digital analysis software which is object- oriented is established. The simulation results anastomose with the experimental data, the software can predict the performance parameters of air conditioner.
