Résumé

This paper presents the main characteristics of an innovative cooling system for automotive applications as well as a first assessment of results obtained with a specifically developed overall model. The system consists of a water- silica-gel adsorption-desorption system, which employs the waste heat from the engine to produce the cooling of the vehicle cabin. The developed global model is completely dynamic and is able to: reproduce the operation of the engine through a standard driving cycle; evaluate the waste heat available at the engine hydraulic loop and at the exhaust gases; calculate the sequential operation of a two-reactors adsorption-desorption system, calculate the condensed water per cycle; the cooling effect produced at the evaporator; and finally, the temperature and humidity evolution of the air inside the cabin. The first assessment of results shows that the system could be able to provide for a significant amount of the required cooling.
