Konvekta with Heat2Go
This year Konvekta AG will be presenting at Busworld the modular heat storage concept Heat2Go for electric city buses. Konvekta promises more than an hour of uninterrupted heat with a capacity of 10 kWh available for electric buses without relying on the batteries.
The Heat2Go research project - a joint venture development with the Fraunhofer Institute for Traffic and Infrastructure systems - is a fast-acting, modular heat storage system for electric city buses. This heat storage system absorbs thermal energy that can be added to the system in a short period of time to be used for heating.
At Busworld, several versions of the Konvekta CO2 heat pump range can be found. In urban traffic, energy consumption plays an important role in heating and cooling, as it can have a significant impact on the range and thus on the operation of buses. By using heat from the ambient air, these thermal systems reduce the energy consumption required for cooling and heating by more than 50%.
Moreover, CO2 is 20% more efficient than conventional refrigerants; in other words, according to Konvekta, approximately 25% less fuel is needed to achieve the same cooling power.
Konvekta also presents a new additional module to save energy costs: "Energy Collect". Waste heat from the axles or the battery is used to heat the vehicle's passenger cabin. According to the initial measurements, approximately 15 to 20% of the required heating energy can be saved in one year. (Hall 5, stand 516a)
