Claim:
1. A charge air cooling system comprising: an internal combustion engine connected to a supercharger; a first heat exchanger for cooling a first refrigerant; a second heat exchanger for cooling a second refrigerant such that the second refrigerant is cooler than the first refrigerant; a high temperature side cooling flow path through which the first refrigerant cooled by the first heat exchanger flows; a low temperature side cooling flow path through which the second refrigerant cooled by the second heat exchanger flows; a charge air cooler connected to the supercharger, the charge air cooler including: a high temperature side heat exchanger that is provided on the high temperature side cooling flow path and cools, by the first refrigerant, supercharged intake air, and a low temperature side heat exchanger that is provided on the low temperature side cooling flow path and cools, by the second refrigerant, intake air cooled by the high temperature side heat exchanger; a bypass pathway, provided on an intake air flow passage downstream of the high temperature side heat exchanger, in parallel with the low temperature side heat exchanger; and a thermostatic regulating valve, for controlling temperature of intake air to be supplied to the internal combustion engine, by regulating: wherein the first refrigerant is refrigerant of an internal combustion engine cooling system, and wherein the second refrigerant is refrigerant of a refrigerant recirculation system of an air-conditioning cycle.
