This paper presents a concept how a hybrid DAE of a vapor compression cycle can be initialized in steady state using the homotopy method.A simplified equation system for a vapor compression cycle is described and its computational causality explained.It is discussed how additional boundary conditions can be applied to the simplified equation system, which do not apply to the actual equation system.The robustness and CPU time for different cases is examined and discussed based on transition plots.
