Abstract
An air cooling system for a vehicle engine includes an air intake configured to receive intake air for delivery to the engine, a first coolant loop thermally coupled to the air intake to provide cooling to the intake air, and a pump for circulating coolant through the first coolant loop. A second coolant loop is thermally coupled to the air intake to provide further cooling to the intake air, and undergoes a vapor compression cycle. A compressor circulates coolant through the second coolant loop. The first and second coolant loops are separate loops using a common condenser. A passive variable charge enabler assembly is configured to remove coolant circulating in the system when the compressor is on.
