Refrigerators equations
WebThe Modelica language offers an innovative way to model systems by using equations instead of assignment statements. Due to this acausality, the same model can have multiple purposes.The technologies modelled are a refrigerator, a combined refrigerator/heat pump and a latent heat storage with spherical phase-change material (PCM) capsules.
