Modélisation d'un système à adsorption pour les applications de conditionnement d'air automobile fonctionnant à la chaleur récupérée : premier bilan de la performance.
Modelling of an adsorption system for automotive air-conditioning applications driven by engine waste heat: first assessment of performance.
Auteurs : CORBERÁN J. M., CORTÉS L., MOLA S., et al.
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.
