The inverted Brayton cycle was reconsidered experimentally and analytically in this paper. The cycle can be operated in the flow passing through the turbine, heat exchanger and compressor by using the exhaust hot gas with near atmospheric pressure. It is noted that the direction of working fluid is reversed in comparison with gas turbines. To confirm the operation of idling and power extracted, the experiment on the various turbine inlet temperature was carried out by a test rig of 30 mm diameter turbocharger. Further calculations, based on experimental data, show that the exhaust energy recovery of 20% can be possible under the conditions of 90% turbomachinery adiabatic efficiency and 1150 K turbine inlet temperature.
