Résumé

Virtual product design (VPD) of the refrigeration cycle has long been a major subject of many of engineers and manufacturers. Issues should be the question of how simulation gets close to the real world by virtual ways. It is especially true when we consider variable refrigerant flow (VRF) heat pumps, having various types of indoor unit
combinations, long and complicated piping configuration, simultaneous cooling and heating functions under extreme weather conditions. The present study deals with the virtual model development for heat recovery VRF heat pumps aiming at reproducing the dynamic behavior of the product in both qualitative and quantitative ways and, thus, saving time and cost caused by the experimental validation during the model development and validation. Toward this end, we used Modelica, an open platform, object oriented modeling language as the backbone of the virtual model. Dymola, a commercial Modelica compiler, is adopted in order to use specialized HVAC libraries. The incorporation of control algorithm and inverter models is done in the form of FMU (Functional Mock-up Units). Testing and validation of control HW/SW is done in ANSYS Twin-builder, where heat pump Dymola model is exported to be FMU in this case.
The choice of open platform SW enhanced synergetic effect among various teams responsible for the components of VRF heat pump system, including cycle model, control algorithm and inverter, and motor models. In the study, the authors share their experience in the virtual design for a VRF heat pump system including the architecture, multiple physics, and the connection with the control SW. Developed virtual model is validated against measured data, showing it can reproduces all the essential physics of interest both in qualitative and quantitative ways.
