Component carrier for CO2 Heatpump System
As part of the further development of the topic management of an electric bus, a specially designed component carrier was implemented as an integral part of the EmCO2s system. EmCO2s-Systems is a climate network for temperature control of all areas in an electric bus: both in the driver's area, the passenger zones and the temperature-sensitive bus components, such as the battery or electrical components.
The component carrier includes energy carrier modules for hot and cold water, a compressor, a booster and a sophisticated battery temperature management system.
The two energy carrier modules of the EmCO2S system collects the heat that is not required in the bus and store it. When required, the heat is given back into the system, directly to the places in the bus interior where it is currently needed. This means the system can heat and cool simultaneously: e.g. cooling the batteries and heating the passenger compartment.
Advantages
- Energy Collect - waste heat generated in the vehicle (e.g. from the axles or the battery) is used to heat the vehicle interior
- Clever-Control - avoidance of unnecessary energy loss
- With 0 emissions, annual energy consumption for cooling and heating is reduced by over 50 %
- Up to 70 % potential service cost savings
- CO2 is a natural, nontoxic and incombustible refrigerant
- 100 % fresh air supply
- Entirely recyclable system and therefore ecologically valuable
