Design and testing of an automobile waste heat adsorption cooling system

This paper describes an experimental adsorption cooling system driven by the waste heat of a diesel engine. Zeolite 13×–water is used as the working pair and a finned double-tube heat exchanger is used as the adsorber. To evaluate the performance of the system, some control and instrumentation facilities are also designed. The time evolutions of the fluids and bed temperature are measured. The coefficient of performance and the specific cooling power of the prototype are obtained. Some challenges facing the commercialization of the automobile waste heat driven adsorption cooling system are discussed.
