A vehicle temperature control unit includes an annular temperature control body (12) of magnetocaloric material over and/or around which heat transfer medium flows and a magnetic field arrangement (24), rotatable about an axis of rotation (A), providing magnetic field heating areas (36) and cooling areas (38) between the heating areas (36). A plurality of heat transfer medium flow zones (40), following one another in the circumferential direction are provided with the temperature control body (12), include two heat transfer medium flow zones (40) adjacent to one another that are associated with a heat transfer medium circulation sector (S). Heat input fluid flows through and/or around at least one heat transfer medium flow zone (50) for feeding heat into this heat transfer medium flow zone (50), or/and heat discharge fluid flows through and/or around at least one heat transfer medium flow zone (52) for discharging heat from the flow zone (52).
