Das Projekt "Thermally OPerated Mobile Air Conditioning Systems (TOPMACS)" wird vom Umweltbundesamt gefördert und von Centro Ricerche Fiat Societa Consortile per Azioni, Thermal Systems, Cabin & HMI, Vehicle Department durchgeführt. Objective: The goal of this project is to develop mobile air conditioning systems with a reduced impact on the environment, both direct and indirect.Two new technologies will be explored:Metal Hydride, either powered by waste heat or by electric energySorption Cooling, powered by waste heatNeither of these technologies uses HCFCs, and so they do not have a direct impact on GWP. The key point is to develop systems that will have also lower indirect impact with respect to state of the art of mobile air conditioning systems. Both technologies has the potential for pre-cooling and pre-warming of the vehicle cabin. In addition to that, the advantages arising from the integration of a near zero Auxiliary Power Unit (APU) based on a Rankine cycle and able to provide electric power and heat (that can be modulated independently) will be evaluated so to study innovative architecture for the energy management of the overall vehicle.Two applications will be considered: Passenger carsLight and heavy trucksThe objective is to set up at least two prototypes: a truck and a car. Benefits for the environment will be quantified by means of calculations and tests in a climatic chamber and on the road. A methodology to evaluate at the same time thermal comfort and the associated energy performance will be developed.
