摘　　要：以逆布雷顿回冷循环为实验流程,对实验工况下的空气制冷机非稳态降温特性进行了实验研究。建立了回冷空气制冷机非稳态数学模型,经与实验结果对比,验证了所建数学模型的合理性及实用性。研究结果为以后小型空气制冷机系统的开发和应用奠定了良好的基础。A small air refrigerator based on reverse Brayton cycle is developed and the dynamic temperature decrease performance of the air fefrigerator is tested. A mathematical model is established to simulate the air refrigerator temperature decrease process. By comparing with experimental data, the model is proved reasonable and effective. By the test research and mathematical simulation, the base for further development and application of small flow rate air refrigerator is provided.
