  • Method for regulating an air-conditioning device having a fresh air and a circulating air supply
    Patent number: 6735966
    Abstract: A method for automatically controlling an air conditioning device includes determining vehicle interior and exterior temperatures, and supplying a mixture of fresh air and circulating air to the air conditioning device in a hot start when the interior temperature exceeds the exterior temperature. An air conditioning device for a motor vehicle includes a hot start mode and a normal mode. In the hot start mode when the vehicle interior temperature exceeds the vehicle exterior temperature, a mixture of fresh air and circulating air is supplied to the air conditioning device. The air conditioning device operates in the normal mode when the vehicle exterior temperature exceeds the vehicle interior temperature.
