中文摘要:
      为得到直升机机载蒸发循环制冷系统性能动态变化过程,校核是否满足设计要求。以国内某直升机为例,基于AMESim仿真平台搭建了制冷系统及座舱的热模型,并通过试验验证了系统的可靠性。在地面初始温度分别为30、35、40、45、50℃时,计算得到地面与飞行两种状态下,舱内空气的温、湿度,以及系统制冷量及性能系数随时间的动态变化关系。结果表明:地面状态时,制冷系统在开机20min后性能达到稳定,且座舱最终温、湿度分别为27℃、60%,满足舒适性指标。在飞行状态下,系统系能受飞行高度影响较大,且海拔越高,系统性能系数越大。建立的仿真模型可以很好的预测在任务剖面下,直升机制冷系统动态变化,为系统的校核及优化提供借鉴。
英文摘要:
      In order to get the dynamic performance of the helicopter evaporative cycle refrigeration system to check whether it meets the design requirements. Based on the AMESim simulation platform, built the thermal model of refrigeration system and cockpit of a helicopter domestic. The reliability of the system is verified by a test. The temperature and humidity of the cabin air, as well as the cooling capacity and the performance coefficient of the system were calculated in both states of ground and flying at the initial ground temperature of 30, 35, 40, 45, 50℃. The results show that the performance of the refrigeration system is stable in 20min at ground state. The final temperature and humidity of the cockpit are 27 and 60% respectively, which meet the comfort index. The system can be greatly influenced by flight height greatly at flying state. And the higher the altitude, the greater the coefficient of performance of the system. The simulation model can well predict the dynamic changes of the helicopter refrigeration system under the mission profile, and provide reference for the verification and optimization of the system.
