ABSTRACT:
A motor vehicle air conditioning installation has a cold loop, a hot loop, a sensor for measuring cabin temperature, a manual setting unit for setting demand values of cabin air parameters, and a control unit for defining the resulting required adjustments to be made to the various components of the cold and hot loops. The control unit includes a temperature estimating module which generates an estimated value of the outside temperature, either from (a) the measured value of cabin temperature (in stabilized operation of the installation), or (b) a temperature value stored in a sub-memory of the control unit (when the installation is converging towards its stabilized mode).
