An Experimental Evaluation On Air Conditioning Performance With Vairtex Air Director Applied On Residential Condenser Unit

Abstract

Thermodynamic performance measurements of a 1.5 ton residential air conditioning system and fluid flow hot-wire velocity measurements at the outlet of the condenser were performed with and without an add-on device (VairTEX Air Director added on top of the condenser unit). 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.
