Engine Exhaust Heat in a New Vapor Absorption Air Conditioning System Development

Abstract

The growing global population has exacerbated the energy crisis, making the need for waste heat recovery more urgent. This paper explores the development of a single-effect ammonia absorption air-conditioning system (1.5 TR) utilizing waste heat from an internal combustion (IC) engine exhaust. The engine exhaust is used as the heat source for the system's generator. The system's performance is evaluated based on trials run over a daily period of 2 hours, with variations in performance plotted. The exhaust system is designed with an automobile exhaust pipe, with heat supplied via a gas cylinder. By heating the system to engine temperatures and conducting trials, the system produces the desired effect, and performance data is analyzed. The aim is to create a sustainable air-conditioning model that reduces energy consumption and avoids ozone-depleting refrigerants. If implemented properly, this research could lead to significant advancements in waste heat utilization and energy-efficient air-conditioning systems.
