Abstract
A distribution box for a heating and/or air conditioning apparatus, particularly for an automotive vehicle, includes at least one fresh air inlet duct, air outlet ducts, regulating means for regulating the distribution and the temperature of the air leaving via the outlet ducts, the inlet duct (or each inlet duct) including an entry section connectable to the outlet section of a feed duct for supplying fresh air in a flow direction substantially tangential to the direction of flow of the air in the inlet duct. The distribution box further includes a distribution grid extending across the inlet section of the or each air inlet duct, the distribution grid comprising a multiplicity of vanes placed in a configuration such as to set up air flows which are differentiated from each other in a controlled manner.
