METHOD OF AIRCRAFT AIR-CONDITIONING AND SYSTEM FOR CONTROL OF THIS PROCESS Russian patent published in 2006 - IPC B64D13/08 B60H1/00 

FIELD: means for control of aircraft air-conditioning equipment.

SUBSTANCE: proposed method consists in control of ventilation of pressurized crew cabin and thermostatting of equipment in unpressurized compartment. Digital computer is connected with signal digital coding unit and is provided with software for realization of algorithm of constant representation, forming and switching of control commands. Switching unit of power control signals is electrically connected with digital computer and is connected to electric drives of control dampers. Power control signal to electric drive of control damper determining the flow rate of used air evacuated from cabin being ventilated depends on magnitude and sign of error of preset and real magnitudes of air pressure in it. Power control signal to electric drive of control damper determining the flow rate of cold air used for thermostatting of heat-generating equipment depends on magnitudes and sign of air of preset and real magnitudes of flow rates of conditioned air fed to crew cabin. Power control signal to electric drive of control damper determining the flow rate of hot air used for ventilation of crew cabin depends on magnitude and sign of error of preset and real magnitudes of: temperature of air in crew cabin and temperature of conditioned air fed to cabin crew or flow rate of conditioned air. Power control signal to electric drive of control damper determining the flow rate of hot air used for preheating the air subjected to expansion depends on magnitude and sign or error of preset and real magnitudes of air temperature immediately after expansion.

EFFECT: automation of air-conditioning system control.
