The ventilation/refrigeration switch on the central control panel is opened to a refrigeration starting gear, the refrigerant is controlled to enter the compressor by the compressor control box, the compressor greatly pressurizes the refrigerant, high-pressure refrigerant steam is converted into liquid state, the temperature of the refrigerant is increased, then the refrigerant enters the condenser, the refrigerant transfers heat to the outside air flowing through the condenser radiator through the radiator of the condenser, the temperature of the refrigerant is reduced, the outside air is increased in temperature and is discharged in the other direction by the condenser fan, then the refrigerant flows through the liquid collection/dryer, the liquid collection/dryer absorbs water in the refrigerant, the water is prevented from interfering the operation of the refrigeration system, a part of the refrigerant is converted into gas state from the liquid state, and the refrigerant is in a gas-liquid mixed state; then the refrigerant enters an evaporator, the pressure of the refrigerant is reduced in the evaporator, the refrigerant is changed from a liquid state to a gaseous state, the refrigerant is changed from the liquid state to the gaseous state to absorb heat, the refrigerant passes through a radiator of the evaporator and absorbs heat from cabin air flowing through the radiator of the evaporator, the temperature of the cabin air flowing through the radiator of the evaporator is greatly reduced, the cabin air is cooled, then the refrigerant enters a compressor again to form a circulation, and cold air flowing through the radiator of the evaporator is extracted by a blower and injected into an air pipeline to be respectively conveyed to each ventilation opening;
The cabin ventilation module ventilation implementation step comprises:
The ventilation/refrigeration switch on the central control panel is opened to a ventilation opening gear, the ventilation/refrigeration distribution motor opens a ventilation air pipeline, fresh air enters from an air inlet of the air conditioner, and the opened air pipeline conveys the air to the cabin and divides the air and conveys the air to the ventilation openings respectively.
10. The aircraft cabin environment integrated control system of claim 9, wherein when the aircraft fails in power or the warming adjustment motor loses power, the warming adjustment motor is unlocked, the torsion spring following the warming adjustment motor returns to an initial position, and the valve plate seals the firewall to prevent the engine from firing or harmful gases from entering the cabin.
