ADDITIONAL ELECTRICAL HEATING DEVICE AND HEATING, VENTILATING AND/OR AIR-CONDITIONING SYSTEM COMPRISING SUCH AN ADDITIONAL HEATING DEVICE

摘要

The present invention relates to an additional electric heating device for heating an air flow, the device comprising a housing (5) comprising a heating compartment (7) intended to house at least one heating module, the housing (5) presenting:A first end (51) comprising at least one opening (52) intended to allow the insertion of the heating module,A closed second end (53) disposed opposite the first end (51), andAt least two sleepers (55) connecting the first end (51) and the closed second end (53),the housing (5) having:A first plane of symmetry (P1) along a plane defined by the longitudinal axis of the sleepers (55) and by the first (51) and second (53) ends, andA second plane of symmetry (P2) perpendicular to the first plane of symmetry (P1), the section line forming the longitudinal axis of the housing (5).
