The energy performances of an elastocaloric device for air conditioning through numerical investigation

•A rotary prototype for air conditioning based on elastocaloric effect is introduced.•A 2D rotative numerical model has been used to design the prototype.•A map of the energy performances under variable operating conditions is presented.•28.5 K and 5400 W kg−1 are the achievable peaks of temperature span and cooling power.•6.22 is the maximum coefficient of performance weighted as 60% of II law efficiency.
