This paper is the first one of a series of research work where will be identified an optimal topology, from a lifetime, cost and thermodynamic point of view, for a device with a principal role of a heat pump. The device itself has a construction similar to hydraulics cylinders. In this paper is presented the general design of the sytem, a work cycle and the first stage of designing, optimising and verifying the integrity of the piston of the first version of the device. The optimisation is realised in Ansys code and consists in a parametric optimisation. The objective function is the reducing of mass, the restrictions consisting in a minimum lifetime of 36600 cycles and a safety coeficient of stability equal or higher than four.
