Future-proof sustainability
Technical development with a focus on energy and resource use - this motto is lived, these are not only words for us and our employees.
Many innovative developments of Konvekta are standard today and are installed in all air conditioning systems.
Some examples:
- Konvekta discoverered the suitability of CO2 as a refrigerant in mobile applications and the developed the first mobile CO2 heat pump for buses and rail vehicles.
- Konvekta was the first air conditioning manufacturer to use reusable metal mesh filters.
- The first fully automatic control system that adjusted power to demand, significantly reducing energy consumption.
- The first components made of aluminum, these were much lighter and saved weight and therefore energy.
- We also developed an ecological housing concept using high-performance materials that help reduce energy consumption while also taking into account weight, material use and recyclability.
CO₂ heat pumps use the natural refrigerant R744. R744 has a Global Warming Potential (GWP) of 1 and contains no PFAS as a refrigerant. Without producing emissions, buses and rail vehicles can be cooled pleasantly for drivers and passengers in summer, and in winter the interior is heated to a comfortable temperature using the ambient air.
With natural CO2 as a refrigerant, considerable energy savings can be achieved in cooling and heating operation, because CO2 has up to 20% higher efficiency than chemical refrigerants, and the target temperature is reached 20% faster.
As a natural component of air, CO2 has a global warming potential of only factor 1 - for comparison: R134a has a GWP of 1,430, while R744 has a GWP of 1.
