An adsorption air conditioning system to integrate with the recent development of emission control for heavy-duty vehicles

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 18 May 2011brYongfang, Zhong , Tiegang, Fang , Kevin L., WertbrThe recent development to control the emissions of large diesel engines has provided opportunities for heat-driven cooling methods in vehicles. An adsorption air conditioning system is therefore proposed in this work for heavy-duty truck application. This system is powered by engine waste heat when the engine of a truck is running. When the engine is off, it can be operated by fuel fired heaters, a newly implemented technology to reduce truck idling. Hence, this system can not only reduce engine emissions but also improve the overall energy efficiency. A lumped parameter model of the system using zeolite-water as its working…br Highlights: ► The recent development to control the emissions of diesel engines has provided opportunities for heat-driven cooling methods in vehicles. ► An adsorption air conditioning system to integrate with the recent emission control devices is studied for heavy-duty truck applications. ► The emission control components applicable to the adsorption system are reviewed and a modular design of the system is presented. ► A model of the system using zeolite and water as its working pair is developed to study the dynamic performance and parametric effects. ► Alternative working pairs and the potential to commercialize the system are also discussed.
