Abstract
A primary air conditioning system for a vehicle has an engine driven compressor which supplies refrigerant to a cooling subsystem comprising a condenser, and expansion valve, and an evaporator. A precooling system has an absorption type system which supplies refrigerant to the cooling subsystem which it shares with the primary system. A combustion unit fueled by the vehicle fuel supplies heat to the generator of the precooling system. The precooling system is used to at least partially cool the vehicle interior before it is occupied, and the primary system is used when the engine is running.
