- Carbon dioxide capturing is necessary to prevent the change in climatic conditions and global warming. This study includes the capturing of carbon dioxide and the conversion of the captured carbon dioxide into useful commercial products. The study has been conducted in the exhaust gases of the highly used 1 ton split air conditioner in domestic applications. The equipment includes the carbon dioxide measuring device at the inlet and outlet. The exhaust gases coming out of the air conditioner are being measured by a digital flow meter and this ensures the mass flow rate of the gases into the unit. The processing unit has been enclosed with a polyvinyl chloride sheet to prevent exposure to the outside environment. In the presence of water two electrodes has been deployed for the conversion of carbon dioxide to carbonic acid and formic acid. For this a protective experimental container has been placed in the vicinity of the air conditioner outlet. The flow rates of the gases into the equipment are measured by orifice plate and manometer. The equipment delivers the two acids with respect to the flow of carbon dioxide. For 1 ton air-conditioning unit 5478kg of carbon dioxide has been produced for eight hours. The study has been conducted with various temperatures in the air conditioner from 20 to 27 °C in increments of 1°C during the morning, afternoon and night time. The processing unit is capable of capturing 65 to 75% of the carbon dioxide exhausted during the operation of the air conditioner. The quality and the cost of the products obtained after the conversion of the captured carbon dioxide are evaluated and listed.
