AI Technical Summary

Technical Problem

Traditional aircraft air conditioning systems in electric aircraft suffer from high energy consumption, low refrigerant cycle efficiency, severe cabin temperature stratification, and isolated thermal management systems, which are particularly evident in high-altitude environments.

Method used

An adaptive heat pump air conditioning system is adopted, which includes closed-loop control of adjustable air inlets, pressure compensation valves, dynamic deflectors and pressure sensors. Combined with a two-stage scroll compressor, external heat exchanger group, cabin airflow module and waste heat recovery module, it achieves stable ram air intake pressure and optimized energy consumption. The system efficiency is improved through high-altitude auxiliary module and waste heat recovery module.

Benefits of technology

Significantly reduces air conditioning system power consumption, improves energy efficiency by more than 40%, ensures cabin temperature uniformity, solves refrigerant circulation anomalies under high-altitude low-pressure environments, and achieves cabin temperature differences of less than 2°C.
