Purpose: As people spend more time indoors, the importance of indoor pollutant management in their homes is increasing. The number of deaths from indoor pollutants has also increased, and interest in indoor pollutants has increased due to the recent COVID-19 virus and fine dust problems. In particular, there is a growing concern about formaldehyde, one of the representative gas pollutants. To overcome the limitations of the mechanical ventilation system, we would like to develop a system that effectively removes formaldehyde from gas-phase pollutants by combining a photocatalytic reactor with a heat transfer exchanger. To this end, we would like to review the performance through experiments in residential studio spaces and contribute to the removal of indoor formaldehyde. Method: This study conducted an experiment to control the concentration of formaldehyde using a heat exchanger combining a photocatalytic reactor to improve indoor air quality. The experiment compared and analyzed the internal circulation mode and photocatalytic mode at three ventilation rates: 0.5ACH, 1.0ACH, and 2.0ACH, and was conducted in an indoor residential studio space. Result: The photocatalytic mode showed significantly better performance than the internal circulation mode in reducing the concentration of formaldehyde. As the number of ventilation increased, photocatalytic modes showed higher formaldehyde concentration reduction rates from 40% to 98%. This has confirmed that the photocatalytic reactor is effective in removing gaseous contaminants.
