我们开发了一个可变制冷剂流量（VRF）蒸汽压缩系统模型，它有五台室内机、一台室外机和一台热水器。VRF系统可以同时运行空间调节（冷却或加热）和水加热。室内机和室外机使用翅片管盘管式热交换器，热水器使用管中管式热交换器。翅片管盘管换热器采用逐段法建模，而管内式热水器采用逐段法建模。所使用的压缩机为变速旋转设计。我们根据制造商的产品资料校准了模型。基于蒸汽压缩系统模型，我们研究了生成VRF设备性能图的方法，该图可用于TRNSYS和EnergyPlus等的能量模拟。在研究中，确定了映射的主要自变量，并量化了简化性能图与实际设备系统模拟之间的偏差。 引文:伊利诺伊州芝加哥ASHRAE会议论文

We developed a variable refrigerant flow (VRF), vapor compression, system model, which has five indoor units, one outdoor unit and one water heater. The VRF system can run simultaneous space conditioning (cooling or heating) and water heating. The indoor units and outdoor unit use fin-&-tube coil heat exchangers, and the water heater uses a tube-in-tube heat exchanger. The fin-&-tube coil heat exchangers are modeled using a segment-by-segment approach, and the tube-in-tube water heater is modeled using a phase-by-phase approach. The compressor used is a variable-speed rotary design. We calibrated our model against a manufacturer's product literature. Based on the vapor compression system model, we investigated the methodology for generating VRF equipment performance maps, which can be used for energy simulations in TRNSYS and EnergyPlus, etc. In the study, the major independent variables for mapping are identified, and the deviationsbetween the simplified performance map and the actual equipment system simulation are quantified.
