Comprehensive environmental control/liquid cold and heat energy management system for non-stamping air inlet duct

Abstract

The invention relates to a comprehensive environmental control / liquid cold and heat energy management system for a non-stamping air inlet duct, belonging to the field of aircraft-mounted equipment and in particular relating to an improved comprehensive environmental control / liquid cold and heat energy management system for the non-stamping air inlet duct. The system is composed of four parts of a two-wheel type high pressure water-removing refrigerating assembly, a liquid cooling system 1, a liquid cooling system 2 and a fuel oil system, wherein the high pressure water-removing refrigerating assembly and the liquid cooling system 1 are coupled through an air-liquid heat exchanger; and the air-liquid heat exchanger is located at the downstream of an air compressor outlet in the two-wheel type high pressure water-removing refrigerating assembly and is located between a fuel oil-liquid heat exchanger and a liquid pump in the liquid cooling system. The system reduces the compensation loss of the refrigerating system property, improves the water-removing and refrigerating efficiency of the refrigerating assembly, effectively reduces the influence on the flight performance of an aircraft, enhances the fuel oil efficiency of the aircraft and has good aircraft economy.

Description

technical field [0001] The invention belongs to the field of aircraft airborne equipment, and in particular relates to the improvement of a comprehensive environment control / liquid cooling thermal energy management system for a non-ramming air inlet. Background technique [0002] The shortcomings of current technology are mainly manifested in the following aspects: [0003] On the one hand, the refrigeration systems currently used on aircraft mainly include air circulation-based environmental control systems and liquid circulation-based liquid cooling systems. The former is generally used for ventilation and cooling of cockpits and electronic equipment, while the latter is mainly used for electronic equipment with large thermal loads. cooling. These two refrigeration systems both use air-to-air heat exchangers or air-to-liquid heat exchangers to transfer the heat load of the cockpit or electronic equipment to the outside atmosphere, which will lead to an increase in the com...

AI Technical Summary

Problems solved by technology

These two refrigeration systems both use air-to-air heat exchangers or air-to-liquid heat exchangers to transfer the heat load of the cockpit or electronic equipment to the outside atmosphere, which will lead to an increase in the compensatory loss of the performance of the refrigeration system and an increase in the flight resistance of the aircraft. and reduced flight performance

[0004] On the other hand, as the flight altitude increases, the cooling load of the environmental control system becomes smaller and the heating load becomes larger, and the thermal load of large electronic equipment is in a full-power working state at high altitude, which requires the largest cooling capacity. The explanation is simple The 1+1 has the problem of insufficient utilization of the cooling capacity of the refrigeration system, indicating that the current system design does not consider the feasibility of using part of the cooling capacity of the liquid cooling system to cool the air of the environmental control system as the flight altitude increases
