Abstract

The invention relates to an airborne combined cooling and heating system used for combining a mixed auxiliary power generation device on a multi-electric aircraft and an ammonia absorption-type refrigeration device. The airborne combined cooling and heating system comprises the mixed auxiliary power generation device and the ammonia absorption-type refrigeration device; the mixed auxiliary power generation device mainly comprises a minitype gas turbine, a high-temperature oxide fuel cell, a compressor and the like; the high-temperature oxide fuel cell is used for generating electric energy; the minitype gas turbine utilizes the residual heat waste gas generated by the high-temperature oxide fuel cell to not only be capable of providing the power for the compressor, but also be capable of generating the electric energy; the ammonia absorption-type refrigeration device mainly comprises a generator, a condensation generation device, a condenser, an evaporator and the like; the ammonia absorption-type refrigeration device utilizes the waste heat exhausted by the minitype gas turbine to carry out refrigeration, thus achieving the object of cooling avionic devices; and the refrigeration device sufficiently utilizes the residual heat waste gas for a series of treatment and cools a part of the electronic equipment. The airborne combined cooling and heating system saves both the electric and the energy.

Description

technical field [0001] The device relates to an airborne combined cooling, heating and power generation system which combines a hybrid auxiliary power generation device and an absorption refrigeration device for refrigeration and electric power of a multi-electric aircraft. Background technique [0002] The multi-electric aircraft is one of the important trends in the development of modern aircraft technology. The multi-electric aircraft replaces the traditional hydraulic, pneumatic and mechanical actuation devices with a unified electric device, so that the structure and layout of the secondary energy system teach traditional aircraft. It is greatly simplified, which not only improves the control flexibility and reliability of the aircraft, but also reduces the weight and flight compensation loss of the aircraft's secondary energy system to a large extent. It is increasingly used in large civil aviation aircraft and military aircraft. Wide range of applications, such as the...
