The automotive industry is facing major challenges: globally increasing consumption and emission requirements are causing the technological transition to electromobility. Adsorption cooling is an ideal solution for reducing the actual consumption of combustion engines. The use of waste heat from the exhaust line and from the cooling water makes it possible to air-condition the interior of cars and trucks – not only while driving, but also when stationary, if configured accordingly.
For trucks, for example, night-time rest periods in hot parking lots can be completely bridged by an adsorption-driven cold storage system without the engine running or imposing an additional load on it while driving. In addition, adsorption cooling uses environmentally friendly and non-toxic refrigerants, so that F-gases regulations and expensive refrigerant alternatives become obsolete.
In contrast to CO2 cooling systems, adsorption cooling has a maximum pressure difference of 1 bar.
The fuel savings for a middle class passenger car in real driving operation was determined to be over 10 g CO2/km.
