Hello,
I understand that Dyad provides core capabilities such as a fluid library and built-in HVAC components (e.g., heat exchangers). From an HVAC control perspective, accurately capturing the dynamic behavior of the refrigerant cycle is essential. At the same time, outdoor conditions and indoor thermal loads also vary over time, and integrating these time-varying effects seems equally important from a system-level simulation standpoint.
In the Modelica ecosystem, for example, some projects couple detailed HVAC models with EnergyPlus through FMI/FMU (such as Spawn). Given the maturity and openness of the Modelica Buildings library, this type of co-simulation framework appears to be a very powerful and practical approach.
I was wondering whether anyone has explored a similar workflow using Julia. More specifically, has anyone tried building a refrigerant cycle using a 1D finite-volume formulation at the ModelingToolkit (MTK) level, and then coupling it with EnergyPlus?
