Summary

The proposal is focused on the development of an Efficient air-conditioning and heating system based on a Magneto Caloric heat pump and a new system architecture to fulfil the thermal comfort and energy requirements of Fully Electric Vehicles (FEVs).

A conventional vehicle uses the engine waste heat to assure the cabin heating and window de-icing and defogging requiring from 5 kW to 10 kW, while a mechanically driven (powered by the engine by means of a conveyor belt and pulley) vapour compression cycle guarantees the cabin cooling and dehumidification, absorbing up to 3 kW and generating up to 5 kW of cooling power.

On a FEV the available heat is limited and at low temperature (e.g.2-3 kW @ 40 °C) and to operate a conventional automotive air-conditioning (A/C) system a relevant amount of energy is required having a significant impact on vehicle autonomy.

For these reasons a specific approach and solution should be identified and adopted to guarantee heating and air conditioning on a FEV.


Within the ICE a new air-conditioning and heat pump system will be developed and prototyped based on a Magneto Caloric heat pump, on the redesign of the cabin air- conditioning and on efficient control strategies offering both high comfort and safety solutions (de-fogging and de-icing).
