摘　　要：Abstract This paper conducts a simulation study of a novel aircraft environmental control system based on membrane dehumidification （MD-ECS）, and compares the system with the up-to-date four-wheel high pressure de-water system （4WHPDW-ECS）. Mathematical models for the two sys- tems are established, and a system simulation using a numerical technique is performed to analyze and compare the cooling performance of the two systems. Simulation results show that the cooling capacity of MD-ECS is much higher than that of 4WHPDW-ECS under the same working conditions, indicating that the novel system is theoretically feasible and promising. The effects of the sweep ratio of the membrane dehumidifier on the dehumidification and cooling performance of the system is also investigated.Abstract This paper conducts a simulation study of a novel aircraft environmental control system based on membrane dehumidification （MD-ECS）, and compares the system with the up-to-date four-wheel high pressure de-water system （4WHPDW-ECS）.
