Abstract:
1. A method of generating a thermal flow from at least one thermal module ( 1 ) comprising at least first and second magnetocaloric elements ( 21 , 22 , 23 , 24 ) through which a heat transfer fluid flows and which are exposed to a variable magnetic field alternately creating, in each magnetocaloric element ( 21 , 22 , 23 , 24 ), a different magnetic phase corresponding successively to a heating and a cooling phase, the heat transfer fluid circulating simultaneously through the magnetocaloric elements ( 21 , 22 , 23 , 24 ) in a manner synchronized with the variation of the magnetic field, and elements of the at least first and second magnetocaloric elements ( 21 , 22 , 23 , 24 ) being exposed alternately to an opposite variation of the magnetic field in order to create simultaneously opposite magnetic phases in each of them, the method further comprising the steps of: connecting the at least first and second magnetocaloric elements ( simultaneously circulating the heat transfer fluid in the at least first and second magnetocaloric elements ( storing, between two magnetically opposite phases, the heat transfer fluid between the at least first and second magnetocaloric elements (
