Simulation of absorption refrigeration system for automobile application

Abstract

An automotive air-conditioning system based on absorption refrigeration cycle has been simulated. This waste heat driven va porabsorption refrigeration system is one alternate to the currently used vapour compression refrigeration system for automotive airconditioning. Performance analysis of vapor absorption refrigeration system has been done by developing a steady-state simulation model to find the limitation of the proposed system. The water-lithium bromide pair is used as a working mixture for its favor able thermodynamic and transport properties compared to the conventional refrigerants utilized in vapor compression refrigeration applications. The pump power required for the proposed vapor absorption refrigeration system was found lesser than the power required to operate the compressor used in the conventional vapor compression refrigeration system. A possible arrangement of the absorption system for automobile application is proposed.
