Abstract:
A heat control method for a heat control device, particularly for a vehicle interior, is disclosed. The method involves detecting, delimiting and positioning various parts of the body of an occupant (U), measuring thermal or physiological parameters regarding various parts of the body of the occupant (U) and/or the vehicle interior around the occupant (U), establishing a plurality of thermal comfort indices (In), each thermal comfort index (In) corresponding to one of the parts of the body of the occupant (U) taking into account a feeling of warmth or of cold in the associated body part, and of which the absolute value is at a minimum in a comfortable situation, and regulating the operation of a heat control device (3) to minimize a sum of the absolute values of the comfort indices (Σ|In|) in order to create a regulated thermal environment around the occupant (U).

Abstract:
A hybrid device (80) comprises, in a first zone (91), at least one thermoelectric element (3) allowing an electric current to be generated from a temperature gradient applied between two of its active faces (4a, 4p). The device (80) further comprises a first circuit (1) able to allow the circulation of a first fluid, and a second circuit (2) able to allow the circulation of a second fluid of a temperature lower than that of the first fluid so as to create the gradient. The device (80) also comprises a second zone (92) so as to allow an exchange of heat between the second fluid and the first fluid. The device (80) is designed so that the first fluid passes through it by travelling in a single direction, referred to as first direction (L), wherein the first zone (91) and the second zone (92) are situated in series in the first direction (L).
