Energy Efficiency Solutions

Energy Efficiency Solutions help operators manage 和 optimize the fleet’s 暖通空调 electricity consumption

  • Our patented RegenAir® allows synchronization of the 暖通空调 function with the train operation phases (acceleration or braking) to benefit from the regenerative braking energy at disposal. When braking, the energy that would otherwise have been wasted is reused for heating 和 cooling. This creates energy savings of up to 20% of 暖通空调 consumption for heating.
  • OptimizAir® is a power converter located directly at the heart of the 暖通空调. This integrated design has positive impacts on the LCC (by reducing the number of starts/stops) 和 saves up to 15% of the 暖通空调 electricity consumption via an optimized frequency adjustment. 暖通空调 reliability is also improved as the need of inrush torque 和 current to drive the compressors 和 fans is reduced. Finally, maintenance is eased as there is only one block instead of two previously.
  • 在冬天, our ReversAir® heat pump makes considerable energy savings from 25% to 45% 和 improves safety. Combined with OptimizAir®, its capacity is adjusted depending on the external thermal conditions while providing a good level of passenger comfort
  • FreshAir® is equipped with CO2 sensors that regulate the quantity of air delivered depending on the number of passengers. It saves up to 30% of the 暖通空调 consumption while ensuring air quality
  • EcoPark® is a plug-和-play patented device allowing railway operators to modulate any 暖通空调 intensity (heating or cooling) at st和still. It automatically introduces a predefined offset to the temperature operating point of the 暖通空调, thus reducing consumption when it is not required. This process saves up to 20% of 暖通空调 consumption while ensuring train availability at all time.
