Internal combustion engine waste heat potential for an automotive absorption system of air conditioning Part 2: The automotive absorption system

Abstract

An automotive air conditioning system based on absorption cycles has been studied. Such a system uses the recovered heat available in the engine exhaust gas. The lithium bromide-water pair is recommended as the working mixture owing to its present technological application level. A possible arrangement of the absorption system for this purpose is proposed. The suitability of such a system has been investigated, taking operating conditions and other standard requirements into account. Finally, the particular features of the proposed scheme are pointed out, and a borderline (at least in stationary conditions) is located in the power-velocity diagram.
