An auxiliary refrigerated air system includes first and second tandemly-arranged auxiliary turbine components, air dividing and mixing valves, an air bypass loop, an auxiliary air compressor, and a heat exchanger. The air dividing valve is connectable to a suitable input air source for receiving and dividing input air into first and second portions. The air mixing valve is connected in communication between an exit side of the first auxiliary turbine component and an entrance side of the second auxiliary turbine component for mixing the first portion of the input air with energy-depleted air exiting from the first auxiliary turbine component. The air bypass loop is connected in communication between the dividing and mixing valves for bypassing to the mixing valve the first portion of the input air diverted from the dividing valve. The auxiliary compressor is drivingly connected to the auxiliary turbine components, connected in communication with the dividing valve, and operable for receiving the second portion of the input air diverted from the dividing valve and producing compressed air upon operation of the first and second auxiliary turbine components. The heat exchanger uses the turbine engine fuel to cool compressed air routed from the auxiliary compressor to the entrance side of the first auxiliary turbine component.

Auxiliary refrigerated air system employing input air from turbine

An auxiliary refrigerated air system includes first and second tandemly-arranged auxiliary turbine components, air mixing and dividing valves, an air recirculation loop, an auxiliary air compressor, and a heat exchanger. The air mixing valve is connectable to a suitable input air source for receiving and mixing input air with dilution air and producing an air mixture. The air dividing valve is connected in communication between an exit side of the first auxiliary turbine component and an entrance side of the second auxiliary turbine component for diverting a portion of the energy-depleted air exiting from the first auxiliary turbine component. The air recirculation loop is connected in communication between the mixing and dividing valves for recirculating to the mixing valve the portion of the air diverted by the dividing valve to provide the dilution air to the mixing valve. The auxiliary compressor is drivingly connected to the auxiliary turbine components, connected in communication with the mixing valve, and operable for receiving the air mixture from the mixing valve and producing compressed air upon operation of the first and second auxiliary turbine components. The heat exchanger uses the turbine engine fuel to cool compressed air routed from the auxiliary compressor to the entrance side of the first auxiliary turbine component.
