Abstract
A device for the climate control of the passenger compartment of an automobile, including an electric fan group, an air distribution conduit in the passenger compartment which has at its entrance an air mixing shutter for diverting a variable amount of the air flow from the fan to a heating radiator, followed by a distribution shutter which sends air either to a defrosting conduit or to an conduit with outlets at the floor of the passenger compartment, electronic probes for measuring the temperature inside and outside the passenger compartment and which are connected to a microcalculator whose memory contains a formula for the interior temperature ordered as well as a law for determining flow from the fan group, both as a function of the outside temperature, the calculator being programmed for receiving temperature measurement data and processing them so as to give off output signals which depend on the temperature ordered and the measured interior temperature, signals to which respond devices for adjusting the position of the micromotors controlling the mixing and distribution shutters mentioned above, as well as means of sending command to supply the heating radiator and signals …
