HEAT-EXCHANGE MODULE OF AIR CONDITIONING SYSTEM OF AIRPLANE Russian patent published in 2016 - IPC F02K3/115 

FIELD: heating.

SUBSTANCE: heat-exchange module of an airplane air conditioning system comprises an air-air heat exchanger, connected by pipelines at inlet with a stop and control device and with one of stages of a high-pressure compressor in a motor, and at the outlet connected by a pipeline to the air conditioning system. The heat exchanger is installed as capable of air supply to its inlet from the external motor circuit. For an airplane with a double-circuit turbojet engine, comprising an external circuit and an internal circuit with low and high pressure compressors installed in it, a combustion chamber with a heat tube, high and low pressure turbines and cooling systems of high and low pressure turbines, made in the form of separate sections of heat exchanges to cool the high pressure turbine and sections of heat exchangers to cool the low pressure turbine, the air-air heat exchanger is made in the form of sections of heat exchangers installed in the external circuit. Sections are connected to the air conditioning system of the airplane and are installed as capable of supplying air that passed through them into the engine nozzle. Inlets of separate sections of the air-air heat exchanger are communicated to the high pressure compressor stage, nominally providing for the air conditioning system. Sections of cooling systems of high and low pressure turbines and sections of air-air heat exchangers are located in one plane along circumference of the external circuit of the engine.

EFFECT: invention makes it possible to increase engine thrust, to reduce engine mass, provides for highest efficiency of heat exchanger operation with minimum increase of their mass.
