ABSTRACT:
An air conditioning system is disclosed for cooling a cabin of a vehicle. The vehicle has combustion chambers and a cooling system which circulates vehicle coolant. The cooling system also includes a radiator and an intake manifold. The air conditioning system includes a source of a liquid gas which is connected to the combustion chambers with a first heat exchanger positioned between the source and the combustion chambers. A coolant line also extends through the first heat exchanger whereby a coolant passing therethrough is cooled via vaporization of the liquid fuel. A pump is connected to the coolant line and circulates the coolant through the air conditioning system. The coolant line is also connected to a second heat exchanger whereby coolant passing through the second heat exchanger is heated and thereby cools the air. The now heated coolant circulates back to the first heat exchanger.
