Presented at: Heat Powered Cycles Conference 2009, Berlin, Germany, 7-9 september 2009.

-A prototype adsorption cooling system was developed for the purpose of on-board test of mobile air conditioning driven by waste heat from the engine. The system was designed, constructed and first tested in the laboratory of ECN. The performance under various static operating conditions was determined in the laboratory. The system can produce 2 kW of chilling power with a COP of 0.4. The prototype was afterward installed in the Fiat Grande Punto demonstration car by CRF. The system was connected to the heating and cooling systems of the car and tested. The performance in the car was comparable to the performance in the lab, indicating that system integration was successful. A waste heat driven adsorption cooling system can be applied for comfort cooling purposes in a car. The amount of waste heat that is freely available in the engine coolant circuit as well as its temperature level is sufficient to drive the adsorption cooling system and to produce enough cold to keep comfortable interior temperatures.
