    Large Capacity Electric Compressor for Air Conditioning System of Hybrid Electric Vehicles

    Mitsubishi Heavy Industries Thermal
    Systems, Ltd.

    Mitsubishi Heavy Industries Thermal Systems, Ltd. has marketed electric compressors for air conditioning systems of hybrid electric vehicles since 2007, and achieved the industry's top class of small, light, and more efficient compressors featuring its unique scroll technology, inverter control system and optimized internal structure. We have developed a new series of large-capacity electric compressors to meet the needs of electric vehicles such as the promotion of battery cooling during rapid charging and the expansion of heating capacity for application to heat pumps. The developed product has achieved a significant increase in cooling capacity while minimizing the increase in body size by optimizing the internal specifications in comparison with the current product.
