  • Patent number: 6668917
    Abstract: An energy-saving method for operating a climate control system includes reporting an ambient outside temperature from a first temperature sensor to a controller unit and reporting a climate control air temperature from a second temperature sensor to the controller unit. The control unit performs an algorithm to define a control criterion value in response to the ambient outside temperature. A non-refrigeration cycle based heating element is activated to provide heated air to an interior surface of a windshield if the climate control air temperature is above the control criterion value. Moreover, a refrigeration cycle based cooling element and the non-refrigeration cycle based heating element are activated to provide the heated air to the interior surface of the windshield if the climate control air temperature is at or below the control criterion.
