METHOD FOR GENERATING A HEAT FLOW FROM A MAGNETOCALORIC ELEMENT, AND MAGNETOCALORIC HEAT GENERATOR

摘要

The present invention relates to a method for generating a heat flow from a magnetocaloric element (1) consisting of at least one magnetocaloric material (2) comprising a hot end (3) associated with a hot chamber (4) and a cold end (5) associated with a cold chamber (6), wherein said method comprises magnetically and alternately activating and deactivating the magnetocaloric element (1), and circulating a coolant through said magnetocaloric element (1) alternately towards the hot chamber (4) and the cold chamber (5) in synchronisation with the magnetic activation and deactivation phases. Said method is characterised in that it comprises inverting the circulation direction of the coolant during said magnetic activation and deactivation phases. The invention also relates to a magnetocaloric heat generator implementing said method.
