Embodiment Construction

[0015] An air refrigeration cycle device with a small ram air flow rate, including a flow control valve 1, a primary radiator 2, a compressor 3, a secondary radiator 4, a regenerator 5, a condenser 6, a water separator 7, a turbine 8, Cockpit 9, fan 10, second turbine 11, second fan 12, motor 13;

[0016] The engine bleed air regulated by the flow control valve 1 is cooled by the hot side of the primary radiator 2, then compressed by the compressor 3 into high-temperature and high-pressure gas, and then passes through the hot side of the secondary radiator 4, the hot side of the regenerator 5, and the condenser in sequence 6 The hot side and the water separator 7 further reduce the temperature and separate the water, and finally enter the turbine 8 to expand and cool down, and then pass through the cold side of the condenser 6 and supply it to the cabin 9;

[0017] The water separated by the water separator 7 is sprayed into the cold side of the secondary radiator 4 and the co...

Abstract

The invention relates to an air refrigeration circulating device with a small ram air flow. The air refrigeration circulating device comprises a flow controlling valve 1, a primary radiator 2, an air compressor 3, a secondary radiator 4, a recuperator 5, a condenser 6, a water separator 7, a turbine 8, a cabin 9, a fan 10, a second turbine 11, a second fan 12 and a motor 13. Engine bleed air which is adjusted by the flow controlling valve 1 is cooled by a hot edge of the primary radiator 2, and the cooled engine bleed air is compressed into high-temperature high-pressure air by the air compressor 3; then sequentially through the hot edge of the secondary radiator 4, the hot edge of the recuperator 5, the hot edge of the condenser 6, and the water separator 7, the high-temperature high-pressure air is further reduced in temperature, the moisture is further separated, finally, the high-temperature high-pressure air without moisture enters the turbine 8 for swelling and temperature reduction, and through the cold edge of the condenser 6, the high-temperature high-pressure air is supplied to the cabin 9. The air refrigeration circulating device disclosed by the invention consists of air turbine refrigeration assemblies and small ram air flow control assemblies. Compared with conventional air refrigeration devices, the air refrigeration circulating device disclosed by the invention has the advantages of being large in refrigerating capacity, small in size, and high in reliability, and the stealth requirements of a high-performance operational aircraft are met.

Description

Technical field [0001] The invention relates to an aircraft environment control technology. Background technique [0002] The main advantages of the air cycle refrigeration technology are: the quality of the equipment is small; the cost is low; the adjustment and control are convenient; the workload of overhaul and maintenance is small; the arrangement of accessories on the aircraft has no special requirements; For pressurization purposes, cabin ventilation, pressurization and cooling can be done by the same system. [0003] The traditional air cooling device uses ram air as the cold side of the system, which has the problem of large performance compensation loss and is not conducive to the stealth of the aircraft. Contents of the invention [0004] purpose of invention [0005] The invention is composed of an air turbine cooling assembly and a small ram air flow control assembly, and has the advantages of large cooling capacity, small volume and high reliability compare...
