Abstract
A temperature sensor is disposed to sense refrigerant temperature discharging from the evaporator of a vehicle air conditioning system. The temperature is averaged over the sampling interval and is inputted to an electronic controller. The controller computes the temperature set points from a lookup table based upon blower speed and blend door settings and cycles the compressor if the averaged temperature is outside the set points.
