Air-Conditioning Unit Microcomputer Air-Conditioning Controller Air-Conditioning Inverter
About 200 years have passed since the world saw the first steam locomotive.
About 50 years have passed since the first air-conditioners were mounted on rail cars in Japan.
With advances in science and technology as well as social and industrial reforms, traffic systems have been evolved and grown in different ways. Operating at the cutting edge, Mitsubishi Electric Corporation calls on its broadly diverse component technologies and systems know-how in its commitment to achieving system integration and meeting the limitless expectations of technologies for next-generation traffic systems.
Compressor Technologies
Mainstream compressors are changing from the reciprocate type to the rotary type and the scrolling type. Mitsubishi Electronic Corporation offers compressors for rail car air-conditioning units with a wide capacity range. It has also developed horizontal compressors for slimmer air-conditioning units. Our compressor lineup supports a wide range of power supply options, from single-phase power to inverter driven power.
ROTARY
Low-capacity compressors for low-power air-conditioners.
The horizontal type for lower-profile air-conditioning units widely mounted on subway cars.•Horizontal type
•Vertical type
Low-vibration low-noise compressors with scrolls used at the compressing component.
Used in high-power air-conditioners among those for rail cars.
The horizontal type is mainly used in rooftop air-conditioning units to reduce height.•Horizontal type

Analysis of Interior Temperature and Air Flow When it comes to rail car air-conditioners, we conduct analyses of the distribution of the interior temperature and of airflow.
Exterior airflow and its analysis model for a ceiling mounted unit for high-speed trains Analysis of airflow from a floor mounted unit for high speed trains and on airflow from a floor mounted unit for the new Shinkansen model Analysis of interior temperature and airflow and on interior temperature and airflow in subway cars 
Presentation Details on Applied Analysis and Structural Analysis We perform analyses on stress or vibration applied to the cover, the frame or piping when an air-conditioning unit is designed.
