Vapor absorption based heating, ventilation, and air-conditioning (HVAC) systems can utilize low-grade waste heat streams to provide heating and cooling. These thermally driven absorption systems use environmentally benign working fluids but require more heat and mass exchangers than conventional vapor compression systems. The implementation of these systems in residential and light commercial market has not been practical for several reasons, including the lack of compact and economically viable heat and mass exchangers. Furthermore, indirect coupling of the condenser in an absorption system to the ambient through an intermediate fluid loop requires additional electrical input for pumping and lowers coefficient of performance (COP) of the system. This study considers the development of condensers directly coupled to the ambient and aims at improving the understanding of heat and mass transfer processes in heat exchangers used in absorption systems.
