Description
The detection and assessment of pollutants emitted from electrical appliances has
become a great area of interest to environmentalists as a means of being aware of the
sources which contribute to the outdoor air quality. In this study, carbon monoxide
emission was assessed from the source, which was the outdoor unit of working split
air-conditioners. Five (5) brands (B1, B2, B3, B4 and B5) of twenty-five (25) split airconditioners
prominent in Covenant University were selected, five split airconditioners
per brand. The exhaust air from the outdoor unit was monitored for one
(1) hour at two (2) minute intervals using the GM8805 Benetech carbon monoxide
monitor. The data obtained were analysed and the daily mean, weekly mean, monthly
mean and yearly mean contributions of each brand to the ambient carbon monoxide
emission were determined. The results of individual contributions to ambient carbon
monoxide emission, on yearly basis, obtained were: 35376 ppm for brand 1 (B1),
57552 ppm for brand 2 (B2), 54384 ppm for brand 3 (B3), 115632 ppm brand 4 (B4)
and 672144 ppm for brand 5 (B5). The air conditioner with the highest contribution to
ambient carbon monoxide concentrations was B5 at 672144 ppm on a yearly basis. It
was concluded that split air-conditioners also contribute emissions into ambient air.
