It is a project that aims to energy saving, to limit environmental impact, to contain costs and to guarantee high reliability by achieving the following objectives:

1. To identify a beneficial energy solution for heating / cooling: heat pump system is an optimal solution, since it guarantees a substantial reduction in electricity consumption;
2. Ottemperare al regolamento vigente in materia di Gas Serra (Regolamento UE n. 573/2024): tale regolamento impone la sostituzione di gas refrigeranti con elevato GWP orientando le scelte verso i refrigeranti naturali (HC e CO₂);
3. To overcome regulatory and safety constraints: in the railway field, there are constraints on the use of flammable or partially flammable refrigerants (HFO and HC);
4. To identify an economically and technically sustainable solution: the technical complexity related to the reversibility of the operation in units with cycle inversion on the refrigeration circuit, involves high costs, as well as limits of reliability and availability of components.
