Novel aircraft environmental control system using high-pressure dehumidifying membrane component

The invention provides a novel aircraft environmental control system using a high-pressure air dehumidifying membrane component. High-pressure air at the outlet of a compressor of a two-wheeled boost high-pressure water removal system is dehumidified through the membrane component, and the membrane component is used as a dehumidifying / heat exchanging total heat exchanger. Compared with the conventional boost high-pressure water removal aircraft environmental control system, the novel aircraft environmental control system has a simple structure, saves a condenser and a high-pressure water separator in the conventional system so as to greatly reduce the weight; and meanwhile, the dehumidifying process of the membrane component is driven by the partial pressure difference of water vapor and the dew-point temperature of exit gas is low, so that the loss of refrigeration capacity of airflow at the outlet of a turbine caused by the condensation of the water vapor in the condenser of the conventional condensation water removal system is avoided, and the process of separating liquid water from the air is also avoided. Therefore, the pressure at the inlet of the turbine can be high, and the advantages of high expansion ratio and temperature reduction in large temperature difference can be fully exerted. The novel aircraft environmental control system has the advantages of simple structure, light weight, energy conservation and high efficiency.
