Overview

Advanced Air Conditioning for Aircraft

The Air Cycling Machine (ACM) is a specialized product developed by Neuros Co., Ltd., designed to provide an efficient air conditioning solution for aircraft. Utilizing open air or engine fan air, the ACM raises air pressure by leveraging the compressor driven by turbine power to supply ventilation air. This system is crucial in maintaining a comfortable and controlled environment within aircraft cabins.

Working Principle
The ACM operates on the principles of the reverse Brayton or Joule cycle, a process fundamental to air cycle refrigeration. In this cycle:
  • Compression: Air is compressed using a high-efficiency centrifugal compressor. The compression raises the air’s temperature and pressure.
  • Heat Removal: The compressed air then passes through a heat exchanger where its heat is removed, resulting in a decrease in temperature.
  • Expansion: The cooled air is expanded in a radial turbine to a lower temperature than before it was compressed, providing the necessary cooling effect.
  • Energy Extraction: Work is extracted from the air during expansion, preventing an increase in entropy and allowing the system to achieve efficient cooling.
  • This cycle effectively manages the temperature and airflow within the aircraft, ensuring optimal comfort and efficiency.
