Abstract
An electronic controller receives an evaporator inlet (or outlet) temperature sensor signal and measures the time required for the evaporator to be heated from compressor clutch cut-out to compressor clutch 'ON'. Depending upon the elapsed time, the controller selects from a predetermined schedule, a new value CLHOFF of the evaporator inlet temperature at which the compressor is next cut-out, raising CLHOFF for lighter thermal loading to prevent evaporator icing and freeze-up and lowering CLHOFF for heavy thermal loading to prevent unwanted compressor cycling.
