German manufacturer Konvekta’s new CO2 (R744) heat pump thermal management system for electric double-decker buses has been nominated for the Innovation Award at the Busworld Europe 2023 trade show, which is due to take place in Brussels from October 7–12.
The manufacturer will also be exhibiting at the trade show in Hall 5 at stand 508.
According to Konvekta, its heat pump can provide both air-conditioning and heating using a fraction of the energy required by traditional mobile HVAC systems or electric heaters.
“At a time when comfort, efficiency and sustainability are becoming increasingly important, the standards for mobile air-conditioning and heating solutions need to be redefined,” said Konvekta. “Our CO2 heat pump thermal management system for electric double-decker buses is a milestone in the development of sustainable technologies in the public transport sector.”

In addition to Konvekta’s R744-based heat pump system, the “all-in-one” Athenia ENVI CO2 heat pump from Thermo King, a brand of Trane Technologies, has also been nominated for the Busworld Innovation Award 2023.
After being shortlisted by an international jury, the winner of this year’s award will be decided by a vote among Busworld attendees.
Previous winners of the award include GEA Bock’s StarCO2mpressor in 2019.
Improved efficiency and range
Konvekta will also be showcasing a number of its other products at Busworld Europe 2023, including its roof-mounted ultralight (UL) 700 CO2 heat pump, which has been found to increase the range of an electric bus by up to 60% and reduce service costs by up to 70%.
The manufacturer will also be presenting its patented “refrigerant charge balancing” system, Additional Energy Storage (AES) software, Energy Collect module and its module for battery temperature control. All of these technologies are designed to improve the efficiency of an electric bus’s heating and cooling systems, as well as improving its range.
