[0037] Embodiment 2: A method for comprehensive control of aircraft cabin environment

[0038] The cabin heating module heating implementation steps include:

[0039] The heating switch on the central control panel 15 is turned to a certain opening position, the heating adjustment motor rotates, and the valve plate inside the heating adjustment box 6 is pulled to the target position through the cable 26, and then the motor stops. Different switch positions correspond to different valve plate movement openings, that is, the adjustment of the cabin heating hot air flow is realized. Fresh air enters from the engine compartment air inlet 22 and is transported to the heat exchanger 5 through the air pipeline. The heat exchanger 5 is in contact with the engine exhaust muffler. The high-temperature exhaust gas in the engine exhaust muffler will transfer the heat to the heat exchanger 5 through the muffler. The fresh air in the heat exchanger 5 is heated and converted into hot air; then the hot air is transported to the heating adjustment box 6 installed on the firewall 25, and the heating adjustment box 6 is connected to the engine compartment air inlet 22 through the cable 2 6 and the torsion spring 4 are mechanically connected with the heating and regulating motor 3, and the heating and regulating box 6 controls whether to continue to let the hot air enter the cabin and whether to exhaust the hot air; the heating switch on the central control panel 15 is turned to a certain opening position, the heating and regulating motor 3 rotates, and the valve plate inside the heating and regulating box is pulled to the target position by the cable 26 and then the motor stops. Different switch positions correspond to different valve plate movement openings, that is, the adjustment of the cabin heating hot air flow is realized. When the aircraft power supply fails or the heating and regulating motor 3 loses power, the heating and regulating motor 3 releases the locking position, and the torsion spring 4 moving with it returns to the initial position. When the power is off, the valve plate blocks the firewall 25 to prevent the engine from catching fire or harmful gases from entering the cabin and endangering the safety of the occupants. The hot air passing through the firewall 25 is divided through the air pipes in the cabin, with one part being delivered to the main driver's air outlet 9, the co-driver's air outlet 10 and the passenger's air outlet 11, and the other part being directed to the defogger ring 8 and sprayed from the air outlet of the defogger ring 8 to the windshield to defog the windshield and prevent the windshield from fogging. A defogger handle 7 is provided at the position of the diversion pipe to adjust the hot air flow distributed to the defogger ring 8;

[0040] The cabin refrigeration module refrigeration implementation steps include:

[0041] The refrigerant is controlled by the compressor control box 16 to enter the compressor 17. The compressor 17 greatly increases the pressure of the refrigerant, and the high-pressure refrigerant vapor is converted into liquid, and the temperature of the refrigerant increases; then the refrigerant enters the condenser 21, and the refrigerant transfers heat to the outside air flowing through the radiator of the condenser 21 through the radiator of the condenser 21, and the temperature of the refrigerant decreases. The temperature of the outside air drawn from the equipment cabin increases and is discharged in another direction by the fan of the condenser 21; then the refrigerant flows through the liquid collector / dryer 20, and the liquid collector / dryer 20 absorbs water in the refrigerant , to prevent water from interfering with the operation of the refrigeration system, and to change part of the refrigerant from liquid to gas, so that the refrigerant becomes a gas-liquid mixed state; then the refrigerant enters the evaporator 19, where the refrigerant is depressurized, and the refrigerant is changed from liquid to gas, and the refrigerant absorbs heat from the liquid to gas, and the refrigerant passes through the radiator of the evaporator 19, and absorbs heat from the cabin air flowing through the radiator of the evaporator 19, and the temperature of the cabin air flowing through the radiator of the evaporator 19 is greatly reduced, cooling the cabin air; then the refrigerant enters the compressor 17 again, forming a cycle. The cold air flowing through the evaporator radiator is extracted by the blower 18 and injected into the air pipeline, and is respectively delivered to the main driver's vent 9, the co-pilot's vent 10 and the passenger vent 11;

[0042] The steps of implementing the ventilation of the cabin ventilation module include:

[0043] The ventilation / cooling switch on the central control panel 15 is turned to the ventilation on position, the ventilation / cooling distribution motor 2 opens the ventilation air pipeline, and fresh air enters from the NACA air inlet 1 installed on the cabin structure. The opened air pipeline transports the air to the cabin and divides it, and transports it to the main driver's vent 9, the co-driver's vent 10 and the passenger vent 11. In this embodiment, the air conditioning air inlet is the NACA air inlet 1.

[0044] When the aircraft power supply fails or the heating and regulating motor 3 loses power, the heating and regulating motor 3 is unlocked, and the torsion spring 4 moving therewith returns to the initial position, and the valve plate blocks the firewall 25 to prevent the engine from catching fire or harmful gases from entering the cabin.

[0045] In summary, the aircraft cabin environment comprehensive control device described in the utility model comprises: a central control panel, a cabin heating module, a cabin cooling module and a cabin ventilation module.
