Abstract
An air-cycle machine (ACM) air conditioning system and method, uses a turbocharger to cool cabin air through expansion. The ACM utilizes an unused, excess, compressed air output from another compressor. A compressor provides compressed air to the intake of an internal combustion engine. The unused, excess, compressed air output from another compressor is diverted to and compressed in an ACM compressor. The output of the ACM compressor is cooled in a heat exchanger and then input to an ACM turbine. The ACM turbine expands the output of the heat exchanger to produce expanded, cooled, cabin air. At least a portion of the expanded, cooled, cabin air can be used to cool an intake charge for the internal combustion engine and/or to cool a passenger cabin and/or other enclosed, refrigerated space.
