This research article represents a study that aims to identify an optimal topology for a heat pump device, considering factors as lifetime, cost and thermodynamics reliability. The device in question is constructed similarly to hydraulic cylinders. Within this paper the overall design of the system, a working cycle and the initial stage of the designing, parametric optimization and validation of the first device’s piston integrity are presented. The first parametric optimization is realized using Ansys direct optimization module, The second one is represented by manuals, iteratives improvements of the model based on post-processing the results obtained from the direct optimization module. The objective function of the optimizations is reducing of mass while the restrictions consisting in a minimum lifetime of 36000 cycles and a safety coefficient of stability equal or higher than four.
