Energy Efficiency And Economic Feasibility Of An Absorption Air-Conditioning System Using Wet, Dry And Hybrid Heat Rejection Methods, Julia Aman, Paul Henshaw, David S-K Ting

Mechanical, Automotive & Materials Engineering Publications

In tropical and sub-tropical regions, air-conditioning systems account for the greatest electricity consumption and high water use. Solar-driven absorption cooling systems can conveniently reduce electricity consumption at need. The performance of this cooling system depends on the system’s heat rejection. A simulation was performed for a 15 kW single effect ammonia-water absorption cooling system driven by low temperature thermal energy and with three different heat rejection methods (wet cooling, dry cooling, and hybrid cooling). This hybrid cooling system uses wet cooling on the absorber and dry cooling on the condenser. The system performance and economics of the chiller with these …
