Abstract
A defrost control for a heat exchange system initiates a defrost of the evaporator coil when a predetermined count of compressor cycles occurs and other sensed conditions indicate that defrost should be initiated. The sensed conditions include a sensed temperature of a condenser coil in the heat exchange system having dropped below a threshold temperature computed as a function of the number of compressor cycles that have occurred since the last defrost of the evaporator coil.
