本文提出了一种半经验建模方法，该方法涉及使用物理表示和参数调整，以预测包含多台具有变速风扇的室内机的可变制冷剂流量热泵系统的稳态性能。系统模型基于半经验组件模型，其中参数使用数据进行调整。半经验模型是基于第一性原理建立的，但经过简化以加快计算速度。由于模型简化，模型与实验数据的偏差通过调整传热系数和系统级的电荷与实验数据进行校正。 根据实验观察，对电子膨胀阀的控制算法进行了估算。该模型内置于模块中，可以灵活地添加更多室内机等组件，或轻松更改控制算法，而无需对解算器进行重大更改。利用一个具有两台室内机的无管道热泵系统的数据进行了案例研究，结果表明，该模型能够准确地模拟在不用于调节的条件下的性能。引用:德克萨斯州达拉斯ASHRAE会议论文。

This paper presents a semi-empirical modeling approach that involves the use of physical representations and parameter tuning to enable predictions of steady-state performance for variable refrigerant flow heat pumps systems that incorporate multiple indoor units having variable-speed fans. The system model is based on the use of semi-empirical component models where parameters are tuned using data. The semi-empirical models are built based on first principles but are simplified to speed up the computation. Deviations of the model from experimental data due to model simplification are corrected by tuning the heat transfer coefficients and charge at the system level with the experimental data. Control algorithms for the electronic expansion valve are also estimated based on experimental observation. The model is built in modules to allow the flexibility to add components such as more indoor units or to change the control algorithms easily without a significant change in the solver. A case study was carried out using data from a ductless heat pump system having two indoor units and results show that the model can accurately simulate performance at conditions not used for tuning.
