    Abstract: An air conditioning system for a vehicle includes a first refrigeration cycle, an expander, and a second refrigeration cycle. The first refrigeration cycle includes a first compressor, a first radiator, a first pressure reducer, an evaporator, and a gas/liquid separator. The expander is disposed on a first fluid communication path between the first radiator and the first pressure reducer. The second refrigeration cycle, which is provided as a cascade cycle, includes a second compressor powered by energy harnessed from adiabatic expansion of the refrigerant at the expander, thereby obviating the need for an additional power source for the second refrigeration cycle. A heat exchanger further is provided on a second fluid communication path in the second refrigeration cycle. The heat exchanger is configured to provide a heat exchange between refrigerant disposed within each of the respective first and second fluid communication paths.
