Embodiment Construction

[0031] The technical solution of the present invention is as figure 1 shown.

[0032] An electric environment control system for a multi-electric aircraft, including an electric pressurized air source subsystem, an evaporative cycle refrigeration subsystem, and a liquid cycle cooling subsystem;

[0033] Among them, the electric pressurized air source subsystem includes a ram air intake device 1, an electric compressor 3, a motor 4, a heating / anti-breathing valve 5, a reverse flow cut-off valve 6, an ozone converter 7, a radiator 8, a temperature control valve 9 and electric fan13. The main function of the electric booster air source subsystem is to suck in external ambient air and pressurize it. Among them, the ram air intake device 1 absorbs the external ambient air from the outside, and prevents external foreign matter from entering the air intake of the aircraft with the external ambient air; The external ambient air is pressurized to obtain a high-pressure air source, a...

Description

technical field [0001] The invention belongs to the field of environment control for multi-electric aircraft, and in particular relates to an electric environment control system for multi-electric aircraft. Background technique [0002] The multi-electric aircraft uses electricity as the main secondary energy source of the aircraft, which has the advantages of high energy utilization rate, low pollutant emission, good system maintainability, and low operating cost. Traditional aircraft use multiple secondary energy systems such as hydraulic pressure, air pressure, and machinery to ensure flight. The coexistence of multiple energy sources has led to problems such as complex structures of aircraft and engines, low energy efficiency, and poor reliability. The multi-electric aircraft introduces the advanced technology of non-bleed air and electric drive, adopts non-bleed air engine, non-bleed air APU, starter / generator, electric environment control and other systems to replace t...
