The German manufacturer’s R744 heat pump provides energy-efficient air-conditioning and heating for electric double-decker buses.
Thanks to using this natural refrigerant for its mobile heating and cooling needs, the ID.5 achieves increased efficiency and range, according to the manufacturer.
The ‘eco2jet’ research project tested Liebherr’s system for three years onboard a long-distance rail vehicle.
The German OEM specializes in CO2 heat pumps for mobile applications like buses and rail.
The Italian manufacturer offers a controller platform with compressor drivers and other components suitable for CO2 mobile air-conditioning units.
Electric heaters require five to six times more battery power than CO2 heat pumps to produce 1kW of heat, says Konvekta.
The CO2 heat pumps can increase the driving range of electric buses compared to electric buses with regular AC units and electric heaters.
The BOXÉR series was first presented to the world at 2019’s Busworld exhibition, and has now completed a period of testing and improvement.
Konveskta’s “Augmented Reality” system connects Its technicians with owners of bus or train systems.
The heat pump can reduce the loss of range that climate control causes, especially in winter.
