Aeronautical Electrical Environmental Control System

This individual analysis project assessed an electrical environmental control system as an alternative to conventional bleed-air systems for helicopters, with possible adaptation to fixed-wing aircraft. The proposed R-134a refrigeration cycle used a compressor, condenser, expansion valve and evaporator with compact plate-fin heat exchangers. Python and CoolProp calculations predicted approximately 103 kW compressor work, 1052 kW condenser heating and 48 percent exergetic efficiency, increasing to about 57 percent after cycle optimisation.
