Abstract:

An optimal design method for an aircraft low-power thermoelectric refrigeration system(TRS)is proposed using an existing experimental model as the research platform under given aircraft flight conditions.The variation curves of the cooling capacities and the refrigeration coefficients of the system running at three flight altitudes are investigated.The performance of the system is evaluated by the minimum-entropy-generation method and the performance penalty is also calculated.The power variation curves of the cooling system are obtained by an electric power experiment.The peak values of these curves are less than the maximal electric power supply of airborne equipment, proving that the use of the low-power TRS for airborne equipment is feasible.The COP, cooling capacity and entropy generation of the system are relative to the flight altitude and the current of the TRS.Through the analyses of these data, the optimal values of the COP are obtained, and the optimization measures are proposed to maximize the use of the advantages of the TRS.
