Performance Analysis of Indoor Smart Environmental Control Factors: Using Temperature to Control the Rate of Formaldehyde Emission

Abstract

Formaldehyde is one of the indoor air quality pollutants produced by indoor decoration. The World Health Organization has listed Formaldehyde as a primary carcinogen. Wood planks for house interior decoration are common sources of formaldehyde. Based on the technology research and development of monitoring and control of the smart home, the air quality should be effectively improved through emission and suppression. This study uses extremely unventilated student renters in Taiwan as simulation spaces. Two classes of wood plank construction materials, F1 and F3, which are classified according to as different concentrations of formaldehyde standard board grades by Taiwanese. Through three different temperature control experiments, each group of experiments use electrochemical formaldehyde detectors to measure at least two consecutive days of data to analyze the influence to which temperature, the control factor, affected formaldehyde emission rate. The results revealed that the F3 class wood planks can increase the rate of formaldehyde emission through heating, which has a significant effect on home environment control, but they need a temperature below 10 °C to barely maintain within the regulations in Taiwan. The F1 class wood planks have an emission rate of nearly zero in a low-temperature environment due to its low formaldehyde emission. The emission rate of the F1 in a high-temperature environment is not as effective as the F3. The addition of experimental data can be used as a reference basis for AI decision making, which is conducive to the establishment of indoor intelligent control systems.
