The invention relates to a method for determining a relative humidity of the air in a motor vehicle passenger compartment, comprising the following steps: —determining a parameter reflecting a specific humidity of the air from a relative humidity (HR) of the air and a temperature (T) of the air in a sensor integrating at least one temperature sensor and one relative humidity sensor, —calculating the relative humidity (HR) of the air in said passenger compartment of the motor vehicle from said parameter and a temperature (T) of the air in the passenger compartment.

Method for determining a relative humidity of the air in a motor vehicle passenger compartment

Heat exchanger, for example for a motor vehicle air-conditioning circuit, comprising a plurality of tubes () for circulating a heat-transfer fluid, the ends of said tubes () opening into manifolds and reservoirs () of thermal storage material in contact with the tubes () so that the storage material and the heat-transfer fluid exchange heat with one another. The exchanger comprises a plurality of heat-exchange elements () each housing at least one reservoir () and at least one tube () which are nested.

Heat exchanger with heat storage

The invention relates to a heat exchanger, in particular for an air conditioning, ventilation and/or heating device of a motor vehicle, said heat exchanger comprising a plurality of stacked modules () which define two series of distinct channels for circulation of first and second heat transfer fluids and are connected to inlet and outlet ducts () for both heat transfer fluids.
