The award-winning system was recognized for its energy efficiency and CO2 reduction. Compared to conventional refrigeration trucks, the TEJ35AM and ELF EV combination reduces annual average energy consumption by 21.3% and CO2 emissions by 46.1%. The system integrates power control between the refrigeration unit and the electric truck, prioritizing temperature stability inside the cargo room while maximizing energy efficiency.
ECCJ’s Energy Conservation Grand Prize Awards highlight outstanding energy-saving technologies and initiatives that serve as models for other industries. MHI Thermal Systems previously won an ECCJ award in 2019 for its TE20/TE30 Series of electric-driven refrigeration units.
The TEJ35AM, launched in 2023, is designed exclusively for EVs and features a heat-pump heating function that enables simultaneous heating and cooling operations. This feature supports multi-temperature transport, making the unit suitable for applications such as convenience store deliveries. The refrigeration unit can operate in all vehicle conditions—including running, idling, parked, or charging—ensuring stable cargo temperatures without requiring constant driver monitoring.
By integrating with the ELF EV, the system also reduces annual energy costs by 42.2% compared to conventional trucks.
With this latest recognition, MHI Thermal Systems reaffirms its commitment to CO2 reduction and energy savings. The company plans to continue developing advanced thermal solutions across various sectors, including refrigerated transport, industrial energy efficiency, large-scale cooling systems, and automotive air-conditioning.
By leveraging its expertise across multiple fields, MHI Thermal Systems aims to deliver innovative technologies that support a more sustainable and energy-efficient future.
