Abstract
Electrical appliances have been suspected to contribute harmful pollutants to the atmosphere hence reducing the quality of outdoor ambient air, this suspicion has given rise to environmentalists carrying out research to determine whether these appliances are pollutant free or not. In the course of this research, carbon monoxide and hydrogen sulfide emissions were assessed from the outdoor part of window air-conditioners. Eight window air-conditioners of four prominent brands labeled as A1, A2, A3 and A4 were identified. The air from the outdoor part of the window air-conditioner was monitored for one hour with readings taken at two minutes intervals using the MSA Altair Xcell 5X Gas Sensor. Raw data of results were obtained for the eight window air-conditioners and they were analysed to obtain the daily, weekly, monthly and yearly contributions of carbon monoxide and hydrogen sulfide to the atmosphere. The yearly contributions of carbon monoxide for each brand was 15360.00 ppm for A1, 15360.00 ppm for A2, 7680.00 ppm for A3 and 5760.00 ppm for A4 while the hydrogen sulfide contributions for each of the brands was 3840.00 ppm for A1, 1920.00 ppm for A2, 0.00 ppm for A3 and 0.00 ppm for A4. From the results obtained, A1window air conditioner had the highest contribution to both carbon monoxide and hydrogen sulfide concentrations in the atmosphere.
