Abstract
A refrigerator is located in a central island or wall of a vehicle. An air duct extends downwardly from the refrigerator through a floor of the vehicle. A fan is installed in the duct to aid air circulation. The fan is controlled by a temperature switch located on a condenser of the refrigerator. Air for cooling the condenser and an absorber are drawn up the duct from outside the vehicle and exhausted outside the vehicle through an upper duct and vent in a roof of the vehicle.
