The Air Director modified all three velocity components at the condenser exit. Data from hot-wire confirmed the Air Director reduced the radial component while enhancing swirling factor and adding 48.7% volumetric flow rate across the condenser unit. By streamlining the flow, the Air Director led to an improvement of 5% in terms of overall coefficient of performance of the air conditioning unit and 4.5% reduction in compressor power consumption.
