Solaris, a Polish bus manufacturer, has recently secured several orders from public transportation operators across the country.
The German manufacturer’s R744 heat pump provides energy-efficient air-conditioning and heating for electric double-decker buses.
The R744-based heat pump reduces operation costs and energy consumption as well as the need to invest in additional charging points or larger fleets, says the German manufacturer.
German manufacturer Konvekta has developed a new software module for its R744 heat pumps that eliminates the need for an electric heater in electric buses, reducing costs and energy consumption.
The German OEM specializes in CO2 heat pumps for mobile applications like buses and rail.
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.
Konveskta’s “Augmented Reality” system connects Its technicians with owners of bus or train systems.
Articulated bus in Nuremburg features two CO2 heat pumps, in the front and rear section.
Regie des transport de Marseille (RTM) is moving to phase out R134a in its mobile air conditioning, running tests using CO2 on two of its new buses in 2015. German manufacturer Konvekta is now bringing its proven MAC technology from the domestic market and Poland, to France.
