ELECTRICAL ADDITIONAL HEATING DEVICE AND HEATING, VENTILATION AND / OR AIR CONDITIONING INSTALLATION INCLUDING 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) having: a first end (51) comprising at least one aperture (52) for inserting the heating module; and a second closed end (53) disposed opposite the first end (51) and • at least two crosspieces (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 as the longitudinal axis crosspieces (55) and the first (51) and the second (53) ends, and • a second plane of symmetry (P2) perpendicular to the first plane of symmetry (P1), the section line forming the longitudinal axis of the housing (5).
